1

3.0 Main Content The art of obtaining an accurate history expeditiously can be acquired and developed with practice.

In history taking, the first task is to listen and observe, not only to obtain information about the current problem but also to understand the patient as a person and his life situation.

Amadi (1996) defined “history taking as an act of obtaining relevant information from a patient which is aimed at making provisional diagnoses of the patient's health status”.

When the history has been obtained, the first step has been taken towards diagnosis. The information must be appraised, taking into account the reliability of the patient as a witness. The relevant facts must be separated from irrelevant ones and evaluated objectively.

When the basic technique has been acquired, skill will improve with experience until an efficient method has been developed.

4.0 Conclusion

In this unit you have learned what history taking is all about.

You should at this point be able to define history taking in your own understanding.

1.0 Introduction

In this unit we shall discuss the concept of interviewing a patient, it will also consider the various questioning technique and types of questions to ask. We shall equally discuss materials required to conduct interview and principles and procedures involved in interview.

4

2.0 Objective

At the end of this unit, the student should be able to:

Define the concepts of interview

Understand the term structured and unstructured

interview (Types)

• Materials for conducting interview

• Principles and procedure involved in interview.

3.0 Main Content An interview is a process whereby someone (interviewer) asks

another, in this context a patient (interviewee) ask series of

questions and records the information supplied. (Eguavoen,

Omorogbe and Omohan 2006).

In a typical interview situation, there is a interviewer and the

interviewee. An interviewer is that individual who formulates and ask

the question(s) while the interviewee is that individual that responds

to questions asked.

3.1 Types of Interview There are several types of interview. These includes structural,

semi- structural and unstructured interview. Interview can be

5

structured or unstructured if the interview is in the form of a well-

prepared list of questions and is carried out in a fairly controlled

environment, then, it is said to be structured. In some cases, the

interaction may be a little bit informal and the interview conducted in

a casual manner, such is an example of unstructed interview.

3.2 Materials for Conducting Interview The materials for conducting interview includes:

Memo pad and pen

Audio Tape Recorder

Questionnaire

Memo pad and pen is very essential tool in conducting interview, because it helps in jotting down the facts of interview by the interviewer.

Electronic device like audio tape recorder is another important material because this aids a replay of recorded version, by so doing eliminates forgetfulness.

Questionnaire is yet another important material for conducting interview, and it comes handy in structured interview.

3.3 Principles and Procedure Involved in Interview

The general principle guiding the conduct of interview is such that the interviewer chooses and arranges an appropriate venue,

6

ensures everything is in place, ensures there is no interruption or disturbance during the interview session, and is also responsible for jotting down of facts or the audio recording. A simple procedure is such that the interviewer introduces the topic, such introduction could/begin from the general to the I specific. He does the asking of the questions, in the process shows flexibility and sensitivity and fact; probes for details or explanation.

And at the end articulates the facts and sum them up.

4.0 Conclusion

In this unit, you have learnt about the concept of interview, and should be able to define it. You have also learnt about the various types of interview and materials you require to conduct an interview. You have equally learnt about the principle and procedures involved in interview. It is hoped that you should be able to now define interview, state the various types of interview, list the materials required for conducting and interview as well as the procedure for interview.

1.0 Introduction

In this unit, we shall discuss approaches to history taking. We will also discuss establishment of appropriate rapport as well as the use of appropriate language and assurance of confidentiality in history taking.

9

2.0 Objective

At the end of this unit, the student should be able to:

Understand how to approach the patient courteously, which

will enhance the patient's co-operation.

• To establish appropriate rapport with a patient

Design a way of building confidentiality on the patient

3.0 Main Content It has been observed over time that patients often find it difficult

to give appropriate information or perhaps suppress vital information

of their health condition, often, these information are information that

the consultant will need in his diagnosis, so in order to ensure that a

patient gives an exact information; it becomes necessary to design a

form of approach that will ultimately encourage the patient to open-

up and give the necessary information without reservation: This can

be achieved by.

3.1 Establishment of Appropriate Rapport To establish an appropriate rapport on a patient involves creating of a friendly relationship with the patient, by simply greeting,

10

smiling, being sympathetic etc. All these will make the patient to respond accordingly and give appropriate information.

3.2 Use of Appropriate Language

The use of language is very important in communication

especially in history taking. This is why a patients language

background is sought before history commences so that if the patient

is not lettered, and the consultant does not understand the patient

language, an interpreter could be assigned to relate the information,

otherwise the patient goes with grudges of not been understood, and

therefore feels inadequate in whatever remedy that will be applied

toward solving the health problems.

3.3 Assurance of confidentiality

The issue of confidentiality in clinical practice is not over- emphasized, no patient wants to be exposed. One of the ethics of medical and health profession is to ensure confidentiality of any patient, to this end, some documents especially the folders are inscribed confidential as a constant reminder not to divulge the health status of the patient.

11

In order to achieve this goal, the consulting room where the information is obtained from the patient is organized in such a way as to aid obtaining this information without necessarily exposing the patient to other workers in a clinical set-up. The process of history taking is one-on-one basis. By so doing confidentiality is built because it is only the consultant that knows the actual health problem of the patient.

4.0 Conclusion In this unit, you have learnt about the approaches to history taking. You have also learnt about the use of appropriate language and how it can enhance understanding in history taking.

The importance of assurance of confidentiality in history taking has also been highlighted to your understanding.

5.0 Summary This unit examined approaches to history taking. It also

focused on establishment of appropriate rapport, the use of

appropriate language and assurance of confidentiality in history

taking.

12

6.0 Tutor Marked Assignment 1. Enumerate three reasons why a patient can suppress vital information.

2. What measures will you put in place to enhance co- operation from your patient in approaches to history taking.

2.0 Objectives

3.0 Main content 3.1 Types of essential clinical history

4.0 Conclusion

5.0 Summary

6.0 Tutor Marked Assignment

7.0 References/Further Reading

1.0 Introduction

In this unit, the focus shall essential clinical history. We will

also discus the types of essential clinical history.

2.0 At the end of this unit, the student should be able to:

Understand the meaning of essential clinical history

Know the categories of essential clinical history

Differentiate between essential and nonessential clinical

history.

14

3.0 Main Content An essential clinical history could be. described as those

important information supplied by the patient, that could assist the

consultant to gain insight into the patient's health problems.

It is called essential history because over time/ patients had

gone out of their way to give information which is not necessary and

therefore not essential. It has been observed that patients instead of

giving a direct information concerning their health status, prefers to

give information about their life style/ family background or social

status. In this process, if the consultant is not patient enough to

listen attentively to the patient's story "he may not be able to gather

essential information that will assist him in diagnosis. Often time

patients had gotten angry with the consultant, because he tried to

stop them from giving irrelevant information which were not

necessary, and had been called names from the patient.

3.1 Types of Essential Clinical History Essential clinical history are grouped into nine broad

categories, as can be seen below.

15

3.1.1 Demographic History

Demographic history includes personal particulars e.g name,

address, sex, age, occupation, next of kin, height, weight, religion

etc.

3.1.2 Present Health History (Current Illness)

This has to do with the immediate complaints of the patient, e.g the current illness that brought the patient to the health facility for treatment. In this regard information required is about the present illness, e.g what is the problems, how serious is the problems, when did it begin, what had been applied for the problems etc.

3.1.3 Past This history is about whether or not the patent has had similar problems before, if yes, was the patient hospitalized, where and for how long, what form of treatment was given.

It should be borne in mind, however, that the diagnosis supplied by patient may not be correct. If medical records are not available the examiner may have to decide about past episodes on the patient description of symptoms and the circumstance at that time.

16

3.1.4 Ante-Natal and Birth History This history is centred around the pregnancy, and child birth. If the woman is pregnant, determine if she is primigravida, multigravida or multipara. Get to know if there is any history of twin delivery, cesarean section, or possible during child birth in the family.

This information helps to ensure that a more adequate attention is given in that regard.

3.1.5 Mental and Developmental History Obtain information on the developmental growth of the patient, because some early childhood impairments tends to re-surface in adulthood. In infants and children in particular, check the rate of their mental and physical development in relation to their age and in comparism to other children within their age bracket.

3.1.6 Immunization History Obtain adequate information on immunization, get to know if

the child completed the schedule of immunization.

3.1.7 Nutritional History

Information about nutrition has to do with the feeding habits, patterns and frequency of feeding, as well as its dietary

17

components required for the individual. Ask if there were situations that gave rise to a patient being kept on special diet, review the implication of such diets, if found hazardous to health, encourage the patient to adopt a possible alternative. We have discovered that most malnourished patients are victims/of personal beliefs, anchored mostly on religion e.g vegetarians.

3.1.8 Family History The state of family income, low, medium or high determines the state of the well being of the individual. If patient's parents are dead, obtain information on the cause of their death. It is a well known fact that certain hereditary conditions play a predominant role in destabilization of most families. Such factor accounts for a possible presence of such a condition in a patient.

3.1.9 Social History

Individual's personal relationship with peer groups, if on the negative side, has an unquestionable potential influence on patient.

Patient's occupation and social environment may, like family influence, have profound repercussion on their health. Therefore

18

inquiry should be made about home, occupation, personal interest and habits.

Patient's leisure pursuits, such as the amount of physical exercise undertaken, and intellectual activities should not be over-looked, as such positive indulgence promotes mental and physical well-being.

Some habits acquired may have disastrous negative implications on health e.g food, tobacco, alcohol etc. most lung diseases and psychological instability have over a long period of time been attributed to tobacco smoking.

4.0 Conclusion

This unit has highlighted the basic understanding of essential clinical history, which you ought to know. You have also learnt about the differences between the essential and non-essential clinical history.

From this unit you have also been informed that essential clinical history are grouped into nine categories, as seen in the main text.

19

5.0 Summary This unit focused on essential clinical history. It also dealt with the types of essential clinical history and the differences between the essential and non-essential clinical history.

1.0 Introduction

In this unit, we shall discuss the principle involved in history taking, the reasons for obtaining correct history and problems associated with incorrect history.

The basic medical or health history of a patient is taking generally with a view to assisting in proper understanding of the patient's present health status.

Certain principles must guide the individual who is obtaining the history of a patient, in order to ensure that an erroneous history is not

21

obtained which can lead to wrong diagnosis and wrong prescription and subsequent treatment.

2.0 Objective

At the end of this unit, the student should be able to

understand the under listed objectives

The basic principle involved in history taking

Reasons why correct history must be obtained

Problems associated with incorrect history

3.0 Main Content

The principles involved in history taking are as follows:

• You don't obtain history from a patient that is under the influence of alcohol. Obtain information from a relative or friend when the patient is unable to supply it because of immaturity, severe illness, senility or mental disturbance (insanity). Obtain an account from an eye-witness in a case of a patient who is unconscious. • Don't try to obtain information from a patient where there is a suspicion that such a patient might surpress vital information, as a result of the environment or exposure eg in the presence of other patients.

22

Timidity, guilt or fear of the disease may cause a patient to surpress vital information.

3.1 Reasons why correct history must be obtained

Correct history must be obtained, because it has been observed that some patient's tend to exaggerate symptoms in an attempt to secure the attention and sympathy of the consultant. On the other hand, most patients with some imperfect medical knowledge tend to give a diagnosis rather than an account of symptoms; such statements must not be accepted without reviewing their bases.

3.2 Problems Associated with Incorrect History

Incorrect history are misleading, often time it leads to wrong diagnosis and wrong treatment. Wrong application of treatment leads to wastage of drugs and eventual death.

4.0 Conclusion In this unit you have learnt about the principle involved in history taking, and should be able to outline them. You have also learnt

23

about the reasons why correct history should obtained, as well as the problems associated with incorrect history.

5.0 Summary

In this unit we were able to see the interplay between the principles of "dos" and "donts" in history taking.

The reasons why correct vital history must be obtained are also highlighted as well as problems associated with incorrect history.

6.0 Tutor Marked Assignment 1. What do you consider as the basic problems associated

with incorrect history.

Procedures or techniques involved in history taking happens to be one of them.

2.0 Objective

On completion of this unit, the student should be able to:

• Understand the procedures in history taking

25

3.0 Main Content

It has been emphasized in the earlier units that it is essential that the patient is put at ease through a courteous and friendly relationship to enable the patient give adequate vital information.

Therefore the first procedure in history taking is to establish an appropriate rapport (friendly relationship) with your patient.

It is also very important to let your patient express how he feels concerning his health without restriction. It is even encouraging to assist your patient in areas of difficulty in explanation of certain health feelings. Show sympathy and re-assure patients in distress condition.

Macleod and Munro (1986) advised that it is essential that record be made without delay basic facts about the history should be written down as it is given. This can be done as quickly as possible with little or ho interruption of the patient. Alternatively the consultant can jot down the main issues, especially in complicated cases, and later do the sequencing and elaborating of the fact.

When the history has been obtained satisfactorily, the first essential step towards diagnosis has been taken. The information must be appraised, taking into account the reliability of the patient as a witness. The relevant facts must be evaluated objectively; the logical analysis and interpretation of the evidence will usually lead to provisional diagnosis.

26

10. Introduction

In this unit, we shall discuss the basic definition of physical examination, and the reasons for conducting physical examination.

The concept of physical examination basically is anchored on the fact that not all diseases or ailments are internal, very many diseases are found externally, and even the ones found internally has clinical manifestation on the physical body. Therefore it becomes necessary to look out for them.

28

2.0 Objective At the end of this unit, the student should be able to understand

the following objectives.

• The basic definition of physical examination

• The reasons for conducting physical examination

3.0 Main Content

Physical examination is defined as an act or a process of

screening for features of diseases in a patient from head to toe.

For an examiner to accurately diagnose an ailment, it is pertinent that the fellow should be familiar with the range of normal signs before abnormalities can be confidently recognized. This is why

Merril C. Sosman in Boston, summarized physical examination as

"seeing only what you look for, and recognizing only what you know"

The individual carrying out a physical examination is entirely and solely responsible for seeking out the features of disease and must not expect the patient to draw attention to them. Occasionally and for a variety of motives according to Macleod and Munro (1996) patients will not reveal what they regard as stigmata of disease, but as a rule failure to recognize these signs are due to careless or inadequate examination.

29

4.0 Conclusion

In this unit, you have learnt the definition of physical

examination, you should by now formulate your own definition base

on your understanding of the passage. You have also learnt why

physical examination is conducted on a patient.

5.0 Summary This unit focused on the definition and concept of physical examination, it also discussed why physical examination is necessary and why it should be carried out in a patient.

1.0 Introduction

This unit shall discuss basically the qualities of a good examiner. Certain qualities must be possessed by a good examiner, according to Oruamabo (1995), an examiner must exhibit a true exemplary qualities, which must be identified in him, to enhance the patient to have confident in making himself available to the examiner for examination.

2.0 Objectives

At the end of this unit, the student should be able to understand such qualities which must be possessed by the examiner'.

31

3.0 Main Content It has been observed that most patients find it difficult to expose their bodies for examination. Part of this problem stems from the way and manner some examiners appear. No patient wants his body to be unnecessarily perused and touched by an un-organized examiner.

An examiners appearance, utterances, reactions etc. is a true reflection of whom the examiner is, and therefore if on the negative side, does not encourage a patient to submit for examination.

a) To this end, therefore, a good examiner must be in a right

mood (happy).

b) Look composed, calm and competent.

c) Must be neat, show love and understanding.

d) Must avoid expressions of disgust, alarm, de-taste or any

other negative reactions resulting from coming in contact with

filthy things etc.

e) Ensure a strict adherence to privacy as most patients will not

co-operate if they are unnecessarily exposed.

4.0 Conclusion

In this unit you have learnt about the qualities of a good examiner and should be able to adopt them. It is a known fact that

32 quality attributes of an examiner accounts for co-operation on the part of the patient. And this can be identified in him by the way and manner he handles issues in relations to physical examination.

5.0 Summary

This unit examined the qualities of a good examiner which is essential in physical examination. It equally outlined the qualities one after the other to enhance understanding.

1.0 Introduction

In this unit, we shall examine the principles and rules involved in physical examination. Physical examination is one such examination that borders on the integrity of both the examiner and the patient. And it is because of these that certain principles and rules must be adhered to in its conduct.

2.0 Objective At the end of studying this unit, the learner would be able to

know the principles and rules involved in physical examination.

38

3.0 Main Content

Ideally in physical examination there is the principle of ensuring

your patient is made to be very comfortable before commencement.

It is salutary to start from one region especially the head region

in general physical examination. Then in a sequential order examine

the other areas.

The general rule of I.P.P.A is to be adopted in physical examination. I.P.P.A. means

I - Inspection: (observation by sight): This rule says carry out physical examination by mere close perusual of the patient; this method will highlight congenital abnormalities, colour, posture, spontaneous movement etc.

P - : (observation by Touch): This method will afford the examiner the opportunity to feel a hard mass under the skin/ which might possibly be a tumour. As a result of palpation the patient may complain of on touching an area of the body.

P - : (observation by sound): In this case tapping with the finger over a cavity will indicate the density of the under laying tissues e.g. posterior chest wall in a pneumonic patient can indicate the localized area of lung involved.

39

A - : (observation by sound): This rule involves

the use of using a stethoscope, the heart/breath sounds

can be heard, as well as abnormalities associated with the

cardiovascular and respiratory region.

4.0 Conclusion

In this unit you have learnt about the principles and rules involved in physical examination. From the understanding in this unit, it's been observed that the patient's comfort is absolutely necessary.

It is also favoured to start general examination from one region and sequentially progress, than haphazardly.

5.0 Summary

This unit focused on the principles and rules involved in physical examination.

Physical examination requires some level of integrity. Its principles and rules must be followed strictly, as outlined in the course of the study.

1.0 Introduction

In this unit, we shall discuss the procedures involved in physical examination. It will also emphasize the issue of compromise in physical examination because It would not be practicable for even the most professional to carry out examination in a patient with some degree of compromise.

42

2.0 Objective

At the end of this unit, the student should be able to:

• Understand the procedure involved in physical examination

• Not compromise with any patient at the expense of the profession.

3.0 Main Content

Before discussing the basic procedures, consideration has to be given to the condition under which the physical examination is conducted.

Privacy is essential and this usually constitutes no problem in the home or the consulting room.

In some families, relatives may feel it is their duty to be present in numbers which may embarrass the patients and the examiner. The tactful dismissal of all, or all but one, is desirable. In a ward, screens must be drawn round the bed before the examination begins.

When necessary, steps should be provided for easy access to a high couch in the consulting room. Comfort is important and encourages adequate relaxation.

Positioning of the examiner counts so much in any examination, as any awkward position impairs perception; therefore you can adjust

43

your examining couch to any reasonable height to ensure the comfort of the patient. Illumination must be good, exposure of the area to be examined must be adequate but not to an extent that might unnecessarily embarrass the patient.

While privacy is important, the presence of a relative or nurse is often desirable and is essential when a rectal or vaginal examination is performed by a male examiner to avoid embarrassment.

Let your patient be well-informed as you progress, remember to relate your findings to the patient appropriately, and if you have missed any portion, kindly explain and politely seek for permission to examine the portion.

Other aspects of procedure include.

• Preparation e.g. Hand washing

• Explanation of purpose to the patient, this may be advisable

mostly if examination commences at a point remote from the

site of complaint.

• General observations for:

i. State of alertness and temperament

ii. Signs of physical or mental disability

44

iii. Signs of chronic illness

iv. State of cleanliness

4.0 Conclusion

In this unit, you have learnt that it is absolutely clear that physical examination follows a procedural approach; which can not be compromised. Anything short of that is unethical

5.0 Summary

This unit examined exclusively the procedure in physical examination. It also dealt with the issue of compromise which is seen as a human factor.

1.0 Introduction

In this unit, we shall discuss the measurement of ital signs. It will also highlight the meaning of vital signs and how to estimate vital sings in a patient. We will equally consider the abnormalities associated with various vital signs.

2.0 Objectives

At the end of this unit, the student should be able to;

• Understand the meaning of vital signs

• How to measure vital signs

3.0 Main Content

Vital signs could be described as the necessary indication in a patient which helps to determine the health aspects of the patient.

Vital signs in a patient consist of measurement of temperature, pulse, respiration (TPR) and estimation of blood pressure.

47

3.1 Temperature Taking

Combs (1976) defined temperature as the degree of intensity of heat especially as measured with a thermometer. According to

Akinpelu, temperature is a degree of hotness or coldness within a substance which can be measured against a standard scale. She further says regulation of body temperature is accomplished principally through thermo regulatory centre located in the hypothalamus of the brain.

3.1.1 Temperature Sites An individual's body temperature can be obtained either from

the:

a. Month b. Rectum

c. Groin

d. Axilla

The normal body temperature is 37°c, but any readin g which ranges between 36.5°c and 37.5°c (97.7° F. to 99.5 °F) is considered to be normal. Amadi (2003).

Surface temperature is 1/4 °c less in intensity th en internal temperature e.g Axilla and Rectum.

48

The highest temperature is found mostly between the hours of

5-8 pm and the lowest between 2 and 6 am, as observed by Ross and Wilson (1970).

Temperatures are classified according to their intensity from collapse to hyper pyrexia.

3.2 Pulse Rate

The mechanism of pulse is the wave of expansion and

contraction of the left ventricle which forces a volume of blood

through the arterial wall into the aorta.

Pulse can be felt at any point where an artery can be pressed

gently against a bone (Pressure point). The most convenient point to

take the pulse is the anterior surface of the wrist. However, other

points include temporal, facial, groin, carotid, femoral etc.

Werner (1979) believes that the best time to take an individual's pulse and arrive at a fairly accurate result is when the fellow is at rest; otherwise a few alterations may be noticed. Conditions that may give rise to such alterations are namely positioning, sex, age etc.

However the normal pulse rate is said to be within the under listed range

49

* Adults 60 - 80 beats per minute

* Children 80 - 100 Beats per minute

* Infants 100 - 140 beats per minute

* Neonates 140 and above

3.3 Respiratory Rate

Respiration is described as the inspiration and expiration of air

brought about by a collection of nerve cells in the respiratory centre

of the medulla oblongata.

Normal respiration should be quiet regular and rhythmical.

There are situations where there can be normal increment in respiratory rate. This occurs during exercise, excitement, emotional out burst or decrease in atmospheric pressure. Normal decrease occurs in sleep, rest or fatigue.

3.3.1 Normal respiratory Rate

* Adults 14 - 20 breaths per minute

* Children 20 - 30 breaths per minute

* Infants 30 - 40 breaths per minute

* Neonates 40 and above

50

3.3.2 Abnormalities Associated with Respiration

Excessive rapidity in respiration may be brought about by disease of the lungs and air passage, febrile conductions, heart diseases, hemorrhage and cranial pressure, coma due to toxaemia, as well as administration of respiratory depressive drugs e.g. morphia and barbiturate overdose.

3.4 Estimation of blood pressure

Blood pressure is that pressure which is exerted on the arterial wall as a result of the total out-put of blood from the heart into circulation.

The brain cells and other vital organs in the body are constantly fed with oxygen which is brought about by this pressure. When the pressure is low, the brain cells suffer from lack of oxygen. Excessive high pressure can result in the rupture of the blood vessels in the brain, as is often the case in cerebral hemorrhage. It is therefore essential that a regular check should be observed to ensure that it is maintained at a normal limit.

51

3.4.1 Factors Responsible for High Blood Pressure.

In the recent years, a number of factors have been identified as pre- disposing causes of high B.P some of them are:

* Environmental factors This consists of day-to-d ay interactions of an individual which brings stress, thinking as well as other parameters encountered in a place of abode, e.g. poverty, broken home unemployment etc., all these can lead to high blood pressure.

* Elasticity of Arterial walls

The constriction of the artery walls inhibits blood pressure. This situation eventually leads to high blood pressure as is often found with patents with severe rheumatoid arthritis and severe varicose veins.

* Arteriosclerosis: This is a state where the arteries or veins are

either thickened or hardened as to reduce the normal pressure in

them. A reduction in pressure, leads to an accreted blood pressure.

3.5 Normal blood pressure

The normal blood pressure is given as 120/80 mmHg (systolic/

diastolic).

52

4.0 Conclusion

In this unit, you have learnt about the measurement of vital signs, and should be able to define it. You have also learnt about the estimation of vital signs and various aspects of vital signs.

It is hoped that you should be able to state the various aspects of vital signs, viz: Temperature, pulse and respiration and to estimate blood pressure, as well as enumerate the normal and abnormal factors associated with vital signs.

5.0 Summary

This unit focused on measurement of vital sings. It also dealt with the various aspect of vital signs and outlined the normal and abnormal factors associated with vital signs.

2 units.

Most clinical thermometers are, however, of dual scale which means they are graduated both in °C and °F. O ne remarkable feature of the rectal thermometer is the blue or red dot at the tip of the bulb.

3.2 Blood Pressure Apparatus

According to Bur-ton (1976), there are two main clinical instruments which are used to determine blood pressure,

* Sphygmomanometer Aneroid

Mercurial

* Stethoscope Dual = Diaphragm with bell

Single = bell or diaphragm only

4.0 Conclusion In this unit you have learnt about the materials required for measurement of vital signs. Measurement of vital signs requires clinical materials, however we have just discussed two out of a lot other materials in use for vital signs.

3.0 Main Content

Tepid sponging is simply defined as an act or a process of the application of tepid (Luke Worm) water to the body of an individual with high pyrexia from head to toe.

3.1 Reasons for Tepid Sponging

Fever or pyrexia is a medical condition that calls for emergency. If this condition is not carefully handled, it could result to some complications or even death. Therefore once fever is noticed, especially high grade fever, efforts should be made to bring it under control to prevent further damage, more so when children are involved. High fever, if not controlled results to convulsion, shock, anorexia, brain damage etc.

The basic reasons for tepid sponging are:

To reduce the intensity of fever in a patient

60

To resuscitate the patient

To prevent complication

To ensure the patient is brought to a level where he

could undertake treatment without reaction

To prevent death.

Conclusion

In this unit, you have learnt about the concept and the reasons for tepid sponging. The skill of Tepid sponging even though very simple has proved to be the very first step in the management of grade fever.

Therefore every individual should strive to undertake simple skill, during the onset of high grade fever.

1.0 Introduction.

In this unit we shall study the instruments and sterilization process. We shall also consider the physical and chemical sterilizing agents used in the health facilities.

2.0 Objective

At the end of this unit, the student should be able to;

• Understand the instruments use in sterilization

• Understand the process of sterilization.

73

3.0 Main Content.

Sterilization is defined as the process of rendering all articles free

from all living micro - organisms. Sterilizing agents can be grouped

into two.

• Physical sterilizing agents.

• Chemical sterilizing agents.

Physical sterilizing agents can further be sub - divided into sunlight, wind, heat etc.

Heat can either be dry or moist. An example of dry heat is hot air oven.

3.1 Hot Air Oven

This method consists of enclosed oven where the articles to be sterilized are subjected to the heated air.

Time of exposure and temperature depends on article to be sterilized. Hot air oven is best for glassware eg glass syringes, but should in no way be recommended for plastics/ Rubber or textile, as an attempt will seriously damage them.

74

3.1.1 Moist Heat.

(a) Boiling. This method is often the practice in the and health center where large scale sterilization is not required. It ensures a complete immersion of items to be sterilized in water e.g. Kidney dishes, forceps, gallipots etc.

It is timed from the point of boiling about 100°c. It is often advisable that sodium carbonate (washing soda) be added to help prevent rusting of metallic instruments.

( b) Steam pressure

The examples of steam pressure apparatus s are autoclave

I steam sterilizer.

The underlying principle of steam sterilization generally, is that an increase in pressure of steam brings about a rise in temperature.

Therefore, the length of time required to sterilized ides at whatever temperature depends on the pressure applied.

3.2 Chemical Sterilizing Agents.

There are a good number of chemical agents available in the drug and chemical manufacturing companies, all over the world.

Some of them are as follows

75

Hibitane

Dettol

Cetalon

Formalin gas

Milton

Savlon Acriflavin

Methylated spirit

Articles to be sterilized in chemical fluids must be rinsed in cold water, washed in hot soapy water and scrubbed with brush to remove all organic materials. It has to be rinsed again in cold water, complicated instruments should be dismantled to ensure a thorough penetration to all parts, then all should be immersed in the fluid which must be an inch above all instrument. Removal of instrument should be by the use of sterile forceps.

4.0 Conclusion

In this unit you have learned what sterilization island that of definition of sterilization, as a process of rendering all articles free n

76

all living micro - organisms; you have also realized that sterilization involves the use of physical and chemical sterilizing agents.

You should at this point define sterilization in your own words and be able to classify the sterilizing agents into the physical and

2.0 Objective

At the end of studying this unit, the learner would be able to understand;

The preparation of salt, sugar solution

78

How to administer salt, sugar solution.

3.0 Main Content

When there is an on -set of passage of watery stool, more frequently than normal, about 2- 5 times a day, and usually, lasting for one to four days, what readily comes to mind, before any other form treatment is the administration of salt, solution (SSS). This is aimed at preventing dehydration and replacement of fluids end electrolyte already lost.

Oral Rehydration therapy (ORT) which is a form of treatment of plain diarrhea from the mixture of salt, sugar solution is based on the scientific knowledge that when the gut is infected, some absorption still takes place. When a solution of salt and sugar prepared in the right proportion is given, the sugar aids the re-absorption of salt and water back into the body, therefore preventing dehydration. This application has proved to be very safe and highly effective in all ages according to Nigerian Medical Association booklet entitled

“Acute Diarrhea /ORT (1995).

3.I Requirements for Preparation of Salt, Sugar Solution SSS)

1.0 Introduction

In this unit we shall discuss the preparation and administration of intravenous fluid. It will also consider the types of intravenous infusion as well as the materials for administration of intravenous infusion. We shall equally discuss the procedure involved in the administration of intravenous infusion, and finally we will take a look at the complications or dangers of intravenous infusion.

83

2.0 Objective

At the end of this unit, the student should be able to:

• Define intravenous infusion.

• Understand the types of intravenous infusion.

• Understand the complications or dangers involved in intravenous

infusion.

3.0 Main Content

Fluid lost from the body occurs in very many ways, and each time it occurs, efforts are made to quickly replace them, or implications will set in. This process of quick replacement resuscitates the patient.

Intravenous infusion is defined as an act of introducing fluids, through the vein into the circulatory system of the body.

Essentially the aim of administering an infusion is to combat dehydration, and maintain the body's electrolyte and water balance.

Burton (1976) emphasizes the use of infusion as that of the replacement of abnormal loses of body fluids and the correction of electrolyte depletion. However, he warned that patients with renal or cardiac disease require special care.

84

Houghton and Parnell (1969) described, intravenous infusion as the quickest and most controlled method of replacing serious loss of water and correcting electrolyte imbalance. Fluid lost may be due to a number of factors, namely, excessive vomiting, diarrhea, choiera, excessive sweating, bleeding, burns, pre and post- operative conditions etc.

3.1 Types of Intravenous Infusion

There are good numbers of intravenous infusion commercially available in our drug stores. The fluid to be administered depends on the condition of the patient, as specific fluids are more tolerable in certain conditions. However it must be on doctor's prescription.

Notable amongst the infusions are:

• Physiological (Normal) Saline

• Dextrose saline

• Ringer's solution

• Hartman's solution

• Antibiotic infusion

• Darrow's solution

85

• Dextran I.V Saline

3.2 Materials for Administration of Intravenous

Infusion

A complete intravenous infusion tray must contain.

• 1 sterile kidney dish with cover

• sterile gdlipots with cover

• pack of adhesive stripping

• Intravenous infusion set/ which must contain hypodermic or

scalp vein needle and a drop counter.

• Sterile piece of toniquette

• In addition, a drip stand is required,

3.3 Procedure for Administration of an Intravenous

Infusion.

The following steps should be followed in administering an infusion.

• Explanation of purpose to the patient

• Washing and drying of hands with soap and water

• Setting of the tray.

86

• Obtain an intravenous fluid set, which is most often

accompanied with half strength solution needle/ a drop counter,

and pieces of adhesive strip.

• Position a drip stand to give at least 45 centimetres (18 inches)

height for the bag above the couch or vein site, this secures a

good rate of flow.

• Tie the toniquette around the site of choice and let the patient

make a fist to ensure the bulging of views for visibility.

• Clean the site on the skin, where the vein will be pierced.

• Expel the air from the tubing by running a few drops of the fluid

out.

• Pierce the skin obliquely until the needle has gone in about one

inch (1 inch) and is in the vein, this occurs when there is a slow,

but free movement of blood back into the tube attached to the

needle, then ask patient to release the fist made.

• Check regularly to see that it is dripping and the fluid is going into

the vein properly, and the punctured site is not tissued.

• Observe for any possible reaction before you discharge the

patient.

87

3.4 Complications or Dangers of Intravenous

Infusion.

A number of complications have been recorded due to careless administration of intravenous infusion, or perhaps situations which do not call for intravenous infusion.

Jumbo (1989) highlighted the dangers of intravenous infusion as that of:

• Air embolism

• Thrombophlebitis

• Septicemia

• Shock

• Gangrene

4.0 Conclusion

This unit has provided sufficient information for the student on the preparation and administration of intravenous infusion. By now the student should be able to define intravenous infusion.

It is from this unit that the student understands the motive behind the administration of intravenous infusion.

88

5.0 Summary

This unit teaches the student that fluid lost is quickly replaced to prevent complication. Fluid lost occurs from various sources, as we were meant to understand.

Many types of intravenous infusion exists, the on e to administer depends on the condition and the prescription of the doctor, the materials for administration are highlighted, and the complications that could possibly arise following the administration of intravenous infusion are also noted.

2.0 Objective

At the end of this unit the student should be able to:

• Understand the principles involved in aseptic techniques.

• Understand the procedures in aseptic technique.

90

3.0 Main Content

The health facility is one institution where all manners of diseases and ailments are treated. In the course of treating them, people get contaminated even without their knowledge. A number of health providers had died while trying to assist patient recover from their illnesses, as a result of contacting infection from either the patient or instruments used in treating patients.

Therefore, in other to reduce the risk of contacting infection, certain principles of aseptic techniques had been developed to solve these problems.

3.1 The Principle of Non-touch Technique

It is a general practice in all health facilities, that all health care providers should not touch fluids or other bodily substances with their bare hands without a glove.

It is equally a principle that you don't touch or administer drug

brought by the patient that had been opened and administered by

some one else.

All instruments for treatment e.g. forceps cannot be touched

with bare hands, no matter how clean the hands are. It is a principle

that all health care providers must appear in uniform and cover - all

91

to perform specific assignment, for instance during a surgical section

all doctors and nurses must wear apron in addition to the usual

uniform.

It is a principle to discard all disposable items immediately, as soon as a specific assignment had been concluded.

3.2 Procedure Involved in Aseptic Technique

In aseptic technique, the procedure is to undertake the "first thing first". All procedures must be top - bottom approach.

4.0 Conclusion

In this unit you have learnt about the principles of aseptic techniques in clinical skills. The student should by now understand the principles guiding aseptic techniques.

5.0 Summary

This unit focused on the principles of aseptic techniques in clinical skills. It also considered the principle of non-touch technique,

92

which is designed to ensure that pathogenic micro-organisms are not introduced in the course of carrying out skills.

All bodily fluids, substance, and instruments should not be touched without a protective device.

All disposables and non disposable are to be adequately taken care of accordingly.

5.0 Tutor Marked Assignment

Name three basic principles of aseptic techniques.

Introduction

Clinical skills are a core component of the study of B. Sc. Community Health.

Clinical skills expose students to techniques and clinical procedures that are necessary in achieving minimum standards for patient care, treatment and management. It is a three- credit unit course for second year students.

Over the years, clinical skills have been counted among the subjects necessary for the study of Nursing Science and Medicine. However, it has different approaches, limitations and applications in the study of B. Sc. Community Health.

That is why it is normally divided into three parts (clinical skills I, II and III) in the study of B.Sc. Community Health.

What you will Learn in this Course

The course consists of Modules, Units and a Course Guide. The course guide tells you briefly what the course is about and what course materials you will be using.

There will be regular tutorials for the course. It is advisable that you attend these tutorial sessions. The course will prepare you for the challenges you will meet in the field in terms of skills acquisition and applications in the management of patients in hospitals and community setting.

Course Aims

The course aims to provide you with an understanding of clinical skills focusing on the approaches and techniques needed to manage patients condition.

Course Objectives

The course has set objectives. Each unit has specific objectives which are mentioned at the beginning of the unit.

You should read these objectives before you study the unit and you may wish to refer to them during your study to check on your progress. You should always look at the unit objectives after the completion of each unit. On completion of this course, you should be able to:

PHS 422 CLINICAL SKILLS II

explain clinical procedures in managing patients’ condition. apply techniques and use of sterile materials in the management. of patients manage patients’ condition and minimise further complication.

Working through this Course

To complete this course, you are to read each study unit, text books and other materials which may be provided by the National Open University of Nigeria. You would also be required to do hospital attachment for practicals.

Modules and Study Units

The course has 20 study units arranged in four modules as follows:

Module 1 Simple Clinical Procedures

Unit 1 Administration of Injection Unit 2 Drip-Setting Unit 3 Use of Diagnostic Set Unit 4 Catheterisation Unit 5 Oral Hygiene

Module 2 Assessment for Clinical Diagnosis

Unit 1 Female Breast Self- Examination Unit 2 Body –Assessment of Dehydration Unit 3 Measurement of Weight to Assess Nutritional Status of Individuals Unit 4 Measurement of Height and Length of a Child Unit 5 Mid-Arm Circumference Measurement Unit 6 Eye – Visual Acuity Test

7 PHS 422 CLINICAL SKILLS II

Unit 1 Collection of Urine Specimen Unit 2 Urine Test for Sugar and Protein Unit 3 Sahli Method of Haemoglobin Estimation Unit 4 Tallquist Method of Haemoglobin Estimation

Module 1 Units 1-5 focus on the application of simple clinical procedures for Administration of Injection, Drip Setting, Use of Diagnostic Set, Catheterisation and Oral Hygiene.

Module 2 Units 1-6 deal with the assessment for clinical diagnosis in areas of Nutritional Assessment, Visual Acuity, Breast Self- Examination and Assessment of Dehydration.

Module 3 Units 1- 5, explain the procedures for simple minor surgery in areas of Wound- Dressing, Suturing of Wound, Male Circumcision, Ear- Piercing and Episiotomy.

Module 4 Units 1- 4 focus on the simple techniques to apply and conduct in routine laboratory investigation of blood and urine specimen. It covers investigation on samples of blood for haemoglobin estimation and samples of urine for protein and sugar test.

This course entails that you spend a lot of time to read and practise skills. I would advise that after the study of each unit, you visit a health facility/hospital to acquaint yourself with the requisite skills.

The course should take you about 20 weeks to complete. At the end, there would be an examination.

However, each study unit consist of one or two weeks work, the session plans include an introduction, objectives, content and reading materials, self assessment exercise, conclusion, summary, tutor- marked assignments, references and further reading. The unit directs you to work through/reading and practice the exercises related to the required content. In general, these are meant to test you on the material content you have just covered and require you to apply it in the most practical way and thereby assist you to evaluate your progress and your comprehension of the course. Together with tutor-marked assignments, these exercises will help you to achieve the stated learning objectives of the individual units and of the course as a whole.

Presentation Schedule

7 PHS 422 CLINICAL SKILLS II

It is important to note that, every study unit has stipulated date and period of tutorials, practical attachment and submission of tutor- marked assignment. You should work and study within the stipulated time frame and guard against falling behind in your work.

Assignment File

There are three aspects to the assessment of the course. The first is made up of self assessment /practice exercises. Second, Tutor -Marked Assignment and third, is the written examination/end of course examination.

At the end of each study unit, you should visit a hospital nearby for practicals, your facilitators will introduce you to the study materials useful for self assessment and regular practicals to enable you acquire basic knowledge and techniques in this course.

Tutor-Marked Assignment

The TMA is a continuous assessment component of your course. It accounts for 30% of the total score. You will be given four (4) TMAs to answer. Three of these must be answered before you are allowed to sit for the end of course examination. The TMAs would be given to you by your facilitator and returned after you have done the assignment. Assignment questions for the units in this course are contained in the assignment file. You will be able to complete your assignment from the information and material contained in your reading, references and study units. However, it is desirable in all degree level of education to demonstrate that you read and researched more into your references, which will give you a wider view point and may provide you with a deeper understanding of the subject.

Make sure that each assignment reaches your facilitators on or before the deadline given in the presentation schedule and assignment file. If for any reason you cannot complete your work on time, contact your facilitator before the assignment is due to discuss the possibility of an extension. Extension will not be granted after the due date unless there are exceptional circumstances.

Final Examination and Grading

The end of course examination for Clinical Skills II will be for about 3 hours and it has a value of 70% of the total course work. The examination will consist of questions, which will reflect the exercise and tutor-marked assignment problems you have previously encountered. All areas of the course will be assessed.

4 PHS 422 CLINICAL SKILLS II

Use your time between finishing the last unit and sitting for the examination to revise the whole course. You might find it useful to review your practicals, TMAs and comment on them before the examination. The end of course examination covers information from all parts of the course.

Course Marking Scheme

Assignment Marks Assignment 1 – 4 Four assignments, best three marks of the four count at 10% each – 30% of course marks. End of course examination 70% of overall marks. Total 100% of course materials.

Facilitation/Tutors and Tutorials

There are 24 hours of tutorials provided in support of this course. You will be notified of the dates, time and location for these tutorials as well as the name and phone number of your facilitator, as soon as you are allocated a tutorial group.

Your facilitator will mark and comment on your assignments and practicals. Keep a close watch on your progress and any difficulties you might face and provide assistance to you during the course. You are expected to mail your Tutor-Marked Assignment to your facilitator before the scheduled date (at least two working days are required). They will be marked by your facilitator and returned to you as soon as possible.

Do not delay to contact your facilitator by telephone or e-mail if you need any assistance.

The following might be circumstances in which you would find assistance necessary, you would have to contact your facilitator if:

You do not understand any part of the study of the assigned readings. You have difficulty with the self tests (Practice Exercise). You have a question or problem with an assignment or with the grading of an assignment. Summary

You should endeavour to attend the tutorials. This would afford you an opportunity to have face to face contact with your course facilitators and

5 PHS 422 CLINICAL SKILLS II

to ask questions which are answered instantly. You can raise any problem encountered in the course of your study.

This course is a study unit of clinical skills. But tutorials and practical clinical skills – will be covered only by a practical attachment in hospital.

To gain more benefits from the course tutorials, please prepare a list of questions before attending them. You will learn a lot from participating actively in discussions.

I wish you success in the course and I hope that you will find it both interesting and useful.

By the end of this unit, you should be able to:

mention the routes of injection set tray for injection select sites for injection.

3.0 MAIN CONTENT

3.1 Overview of Administration of Injection

This gives an insight into the administration of injection as a simple clinical procedure for introducing drugs into to the body by the use of

1

syringe and needle. It is usually done manually by a medical practitioner in a hospital setting, /centre and health units.

The standard route for giving injection and technique to apply in the process involved are as stated below;

3.2 Routes of Injection

Intramuscular – injection through the muscles, at angle of 90(degrees) deeply. Intravenous – injection through the blood vein Subcutaneous – injection through the subcut layer at angle of 45(degrees)

3.3 Sites for Injection

Buttocks - upper outer quadrate Thigh – upper outer muscle Vein-inside the vessel Arm-upper outer muscle

F ig.1.1: Diagram of Injection Sites (Modified from CHO Training Curriculum)

3.4 Injection Tray

Before you start the procedure of injection, all the items needed should be assembled in a tray or trolley and these should include:

Kidney dish with lid, containing sterile needle and syringes. A Galli pot with swabs Methylated spirit

3

Kidney dish for used swabs Kidney dish with a pair of forceps Container with drugs / injection vials and ampoules

3.5 Procedures for Injection

These are steps you should follow in giving injection:

explain procedure to the patient / client select and clean the site which can be the arm, thigh, buttock or vein read the label on the drugs for the expiry date before using it. use a syringe to draw drugs to the correct amount and expel the air bubbles insert the needle at an angle of 45 if its subcut routes at angle 90 deeply into the muscle’s intra muscular route. draw the plunger to make sure you are not in a blood vessel (artery or vein) insert your drug remove your needle and wipe the site with the swab. for subcutaneous injection repeat the same procedure above except for intravenous injection, then you do the following:

- pierce the skin obliquely until the needle has gone in about a half to one inch and blood can be seen at the tip of the syringe - draw blood a little and inject the prescribed drug - apply puncture with little pressure to the site until bleeding stops.

4.0 CONCLUSION

In this unit, you read that administration of injection is done manually using syringe and needle. You are to visit a hospital and apply the procedure of injection under the supervision of a qualified personnel or medical practitioner.

1.0 INTRODUCTION

In the previous unit, the administration of injection was covered and this unit is an aspect of it, because setting of drip is a line of intravenous infusion of fluid or drugs which has similar procedures with giving injection. However, it differs only in principle and instructions.

2.0 OBJECTIVES

By the end of this unit, you should be able to:

assemble the materials needed for setting drips set drips.

3.0 MAIN CONTENT

3.1 Overview of Drip -Setting

Drip -setting is a simple clinical procedure for the administration of fluid, water and electrolyte, including drugs (injectable via veins) into human body to modify action. The setting of drips involves three sequential processes. These are: fixing of electrolyte fluid to the given set tube, then attaching the set to the human body through blood vessel, timing and setting of flow rate of the fluid in the drip.

3.2 Materials for Drip -Setting

Tray Kidney dish containing sterile needles and syringes Galli pot with spirit swabs

6

Kidney dish for used swabs Tourniquet

NB: An intravenous given set containing needle tubing and a drop counter (is supplied in a complete set).

Plaster or adhesive strapping A drip stand

3.3 Procedures for Setting a Drip (Intravenous line of infusion)

Set a tray containing all the materials needed for drip –setting. Obtain a drip stand and place it closer to the patient/client (stand should be at least 45cm (18inches) in height (Above the veins, site- patient’s bed) Select the site/vein with the swab Assemble the tubing solution according to the manufacturer’s instruction Let out the air from the tubing by letting some of the fluids run down the tubing. Tie a tourniquet tight above the site where the veins will be pierced or hold the skin above the site tight to make the veins prominent/visible Pierce the skin obliquely until the needle has gone about one inch, and is in the veins (this occurs when there is a slow, but free movement of blood back into the tube attached to the needle) Release the tourniquet Fix the needle in place with adhesion strapping Hang the bag at the correct height so that the fluid is dropping according to the prescribed rate per minute. Check regularly to see that the fluid is dropping and that fluid is going in to the vein properly and that the puncture site is not swollen.

4.0 CONCLUSION

This unit has elaborated on the steps to follow in setting drips, you are required to assemble the materials needed and applied in setting the line process.

5.0 SUMMARY

You recall the steps, procedures and materials needed for setting of drip were extensively discussed in this unit. However, regular application of

7

these procedures in a hospital setting will not only make you to acquire the skills, but to have adequate experience in setting infusion line.

1.0 INTRODUCTION

In the previous unit, weight of a child was described as a method of assessing nutritional status. Similarly, this unit will discuss measurement of child length and height as another method of assessing nutritional status of a child.

2.0 OBJECTIVES

By the end of this unit, you should be able to:

measure height and length of a child identify the equipment needed for measurement of height and length.

3.0 MAIN CONTENT

3.1 Overview of Measurement of Child Height and Length

A child’s height and length in centimetres or inches is measured in order to assess his nutritional status. This determines how tall a child is, when the child is standing upright. Also, length measurement will be able to show how tall or long a child is, but this is done when the child is lying down. While, height is not necessarily dependent on the age of the child.

25

Height measurement is used for children 2 years and above while length measurement is used for children below 2 years of age because of their inability to stand upright.

The average length or height of a child at birth is 50 cm and this doubles after a year.

3.2 Equipment Needed for Measurement of Height and Length

Adult weighing scale which has graduated height indices Measuring tape calibrated in centimetres and inches A long plank or wall, graduated in centimetre from ground/ floor level which is zero(0) point

3.3 Measuring of Height and Length

(Adult and older children)

Ask subject (Adult and older children) to remove heavy objects, materials and clothes from their body e.g. shoe, head tie, cap, hat, bangles, handset. Adjust scale –by forwarding headpiece up right to the graduated measurement wall scale or long plank his/her feet parallel, with heels, buttocks, and back of head touching the graduated measurement board /mark Allow his/her arms to hang freely in a natural standing manner Adjust scale to down ward, lower the head piece gently to make contact with the top of the head of the client If subject is standing against wall or plank use any flat object to represent the head piece with the top of the head With the head piece at the correct graduation point Take reading and remove the lead piece Allow subject to get down

Infant and Children Below 2 Years of Age

Explain procedure to child or mother Get the Child’s co-operation Remove heavy materials, shoes, bangles, head tie, hat , cap from the child Solicit for help from two trained persons to assist in getting the child into appropriate position, since most children become upset and struggle when measurement is being taken

26

Place the child in recumbent or lying down position on flat surface/board so that the child is looking straight up, Place the foot piece firmly against the child’s feet and make sure the knees are straight Read and record the length to the nearest 0.1cm

4.0 CONCLUSION

Measurement of height and length provides a basis to compare and relate the weight of a child with his height and length. It is an unbiased measurement that can ensure that even a child’s degree of thinness and stunted growth can be obtained.

5.0 SUMMARY

Use of relevant scale for measurement of length and height can provide accurate reading while the use of relevant scale and wrong positioning of client/subject on the measurement scale can yield wrong reading/result.

Board/scale can be used in the hospital set up. In the community or any place where there is no measurement board/scale, a graduated wall/plank can be used to assess length and height of an individual.

6.0 TUTOR-MARKED ASSIGNMENT

State three (3) possible reasons for wrong reading of individuals’ height and length

3.2 Procedures for Measuring Vision Using E-Chart

Identify a place to conduct the test such as a room or Hall that has good light, not too bright or dark. Stand or Sit Patient 6 meters from the eye test chart (use ruler or tape to measure the distance). Hang or paste E-Chart on the wall or pillar 6 metres distance to the patient. Test both eyes one after the other. If patient wears glasses, test only with the glasses on. Explain and tell patient to indicate with hands which direction the 3arms of E. are pointing. Starting from top line of the test E-Chart, carefully point to the “E”s. Patient is to cover one eye with palm of hand or cardboard and read the chart with the one uncovered. The test line that is seen correctly is the visual acuity in that eye

32

Record visual acuity as fraction e.g. . Where the numerator

(6) indicates the distance of the patient from the E-chart and is the distance at which a normal eye can read the E- Chart:

Thus: V = Visual R = Right Eye L = Left Eye

VR VL

Both eyes are to be tested but one at a time.

Common Signs of Visual Defect during E-Chart Test

- Exclusive eye-blinking - Thrusting head forward - Tearing or red of eye - Head felting - Eye squinting

4.0 CONCLUSION

Visual acuity test using E-chart is not only a skill to measure eye vision, but to identify common eye defects.
