Unit 4: Medication Administration Fundamental of Nursing Unit 4: Medication Administration Fundamental of Nursing Unit 4: Medication Administration: Medication: Is a substance administered for the diagnosis, cure, treatment, relief, or prevention of disease. Six Rights of Medication Administration After paramedics have received the medication or fluid order, they should then administer the drug in question. In performing drug administration, pre-hospital care providers adhere to the six rights of medication administration: 1. Right patient 2. Right medication 3. Right dose 4. Right route 5. Right time 6. Right documentation Basic principle of nurse on drugs administration 1. The nurse must know the drug's prescribed dose, method of administration, actions, expected therapeutic effect, possible interactions with other drugs, and adverse effects. 2. The nurse must know the institution's administration procedures for the client's welfare and the nurse's legal protection. 3. The nurse must Review physician's order for completeness the client's name, date of the order, name of the drug, dose, rout, time of administration, and the physician's signature. 1 Unit 4: Medication Administration Fundamental of Nursing 4. The nurse discusses the medication and its actions with the client; recheck the medication order if the client disagrees with the dose or the physician's order. 5. The nurse must check the physician's order against the client's medication administration record for accuracy. 6. The nurse gives the patient the right to know about the medication he is receiving and the right to refuse it. Routes of Administration A: Enteral Tract Routes The common enteral routes of administration used in general medical practice are as follows: 1. Oral: The best, and most convenient, way of administering drugs is by mouth. The effects of oral administration are often not seen until 30 to 45 minutes after administration. 2. Orogastric/nasogstric tube (OG/NG): This route is generally used for oral medications when the patient already has the tube in place for other reasons. 3. Sublingual (SL): Some drugs can be administered sublingually, the drug is placed under the tongue, where it quickly dissolves. The drug is then absorbed into the vast capillary network present in the mucous membranes. 4. Buccal: Absorption through this route between the cheek and gum is similar to sublingual absorption. 5. Rectal (PR): Rectal administration may have both local and systemic effects. It may be necessary to administer some medications rectally, especially if the patient is nauseated. The rectal route is frequently used in infants and children, who may not be able to swallow oral medications. 2 Unit 4: Medication Administration Fundamental of Nursing Absorption of rectally administered drugs is generally somewhat slower than by the oral route. B: Parenteral Routes Any method of administration that does not involve passage through the digestive tract is termed parenteral. Parenteral routes include the following: 1. Topical: Certain drugs can be placed on the skin, where they are slowly absorbed into the capillary network underneath the skin. 2. Intradermal: Drugs can be injected into the dermal layer of the skin. 3. Intranasal: The drug is aerosolized and instilled in the nose, whereby the drug is rapidly absorbed through the massive vascular network in the nasal tissues. 4. Subcutaneous:. With subcutaneous administration, medications are injected into fatty, subcutaneous tissue under the skin and overlying the muscle. 5. Intramuscular:. The most commonly used route of parenteral medication administration is the intramuscular route. 6. Intravenous. Most medications used in emergency medicine are designed to be administered intravenously. 7. Endotracheal: Sometimes it is possible to administer emergency medications down an endotracheal tube, which permits absorption into the capillaries of the lungs. 8. Sublingual injection: Certain drugs can be injected into the vast capillary network immediately under the tongue. Lidocaine is the agent most frequently given by this route. 3 Unit 4: Medication Administration Fundamental of Nursing 9. Intracardiac: Injection of a medication directly into the ventricle of the heart is referred to as intracardiac administration. 10. Intraosseous: When an IV line cannot be started in children under 6 years of age, many emergency medications can be administered intraosseously. A needle can be placed in the anterior aspect of the proximal tibia, through which medications and fluids can be administered. 11. Inhalational: Medications can be administered directly into the respiratory tree in cases of respiratory distress resulting from reversible airway disease including asthma and certain types of chronic obstructive pulmonary disease. These medications are usually nebulized into a water vapor and breathed with normal respiration. 12. Umbilical: Both the umbilical vein and umbilical artery can provide an alternative to IV administration in newborns. 13. Vaginal: Medications can be placed into the vagina, where they are absorbed into surrounding tissues. Most vaginal medications are supplied in creams or vaginal suppositories. The onset of action is slow, and the effects are generally limited to the lower female genital tract. Non-parenteral Rout Medication Administration Oral medication administration Definition: is the most common and convenient type for most clients by which the drug is swallowed to the stomach, or administrated under the tongue for slow action. Purpose 1. To provide safe, effective drug therapy with minimal complications and discomfort. 2. To provide a convenient route for drug therapy. 4 Unit 4: Medication Administration Fundamental of Nursing Advantages 1. It's the easiest, least expensive, safe, and most desirable type of drug to administration. 2. Has the slowest onset of action because it is absorbed through the gastric mucosa into the bloodstream for a systemic effect. 3. Can have a local effect (for example, anti-acids) 4. Is supplied in the form of tablets, capsules, enteric-coated tablets, liquids, syrups, and suspensions Disadvantage 1. Unpleasant taste of the drugs. 2. Irritation of the gastric mucosa. 3. Irregular absorption from the gastrointestinal tract. 4. Slow absorption. 5. Harm to the client's teeth. 6. Is contraindicated in a client who is vomiting or cannot swallow food or fluids, who is having gastric suctioning, or who lacks mental awareness. Topical Administering Skin Application Definition: is the applied of substance to a circumscribed surface area of the body. Purpose 1. To facilitate absorption through the skin or mucous membranes. 2. Provide local anesthetic effect 3. To stop slow, or prevent microbial growth. 5 Unit 4: Medication Administration Fundamental of Nursing Advantages 1. Is applied externally to the skin or mucous membranes. 2. The pharmaceuticals forms used in topical and skin administration are including (lotions, liniments, ointments, pastes, powders, patches, creams, gels, jellies, foams, Aerosol spray). 3. It requires use of sterile supplies and sterile techniques when applied on open skin lesion such as sterile applicators. 4. Can create systemic and local effects if absorbed through the skin. 5. Can be applied into body cavities or orifices, such as the urinary bladder, eyes, ear, nose, rectum, or vagina. 6. Can be administered by inhalation into the respiratory tract by a nebulizer. Disadvantage: Not absorbed well (completely) Administration of vaginal and rectal instillations Purpose 1. To provide an alternative route of administration. 2. To promote bowel elimination. 3. To treat vaginal infection, pain, or itching (local effect). 4. To treat rectal hemorrhoid and fissure (local effect). Characteristics 1. It's a safe, alternative method of medication administration. 6 Unit 4: Medication Administration Fundamental of Nursing 2. It's usually supplied as a solid cone- or oval shaped mass of medication dissolved in a wax like substance; body heat melts the wax and release the medication to be absorbed. 3. Provide a local or systemic effect. 4. Rectal suppository is contraindicated with cases of rectal surgery or active rectal bleeding. Administration of Eye(ophthalmic) medication. Definition: medications that instilled in the form of liquid or ointment and indicated for ophthalmic use. Purpose 1. To provide local anesthetic effect. 2. To decrease intraocular pressure. 3. To dilate the pupil for eye examination. 4. To treat ophthalmic infection. Characteristics of Eye medication administration: 1. It's instilled the medication as a sterile liquid, drops, or an ointment. 2. Sterile preparation and sterile technique are indicated. Administration of Ear (otic) medication. Purpose 1. To relive ear pain. 2. To provide local therapy to reduce inflammation by otic antibiotic medication. 3. To soften ear wax for removed at later time. 7 Unit 4: Medication Administration Fundamental of Nursing Characteristics of Ear medication administration 1. It's supplied as drops in plastic or glass container with dropper. 2. Requires a sterile technique to instill medication special if tympanic membrane is damaged. Administration of nasal medication Definition: medications that instilled for shrink swollen mucous membranes, loosen secretion and facilitate drainage or to treat infection of sinuses. Characteristics of nasal medication administration: 1. Nasal drops are used to treat sinus infection. 2. Small doses are needed. 3. Nebulizer bronchodilator medication can be administrated in emergency cases. Parenteral Rout Medication Administration:

  • Nerve Block of Lateral Femoral Cutaneous Nerve of the Thigh
    18VTLLAA 1 Nerve block of lateral femoral cutaneous nerve of the thigh. Dr. Robert M Raw (MD) . MBChB, MFGP, MPraxMed, DA, FCA. Professor of Anesthesia retired Editor of Regional-Anesthesia.Com INDEX. 1. Introduction 2. Anatomy 3. Choice of local anesthetic 4. General indications 5. Complications and side effects 6. Conclusion ------------------------------------------------------------------------------------ 1. INTRODUCTION The lateral femoral cutaneous nerve of the thigh (LFCN) is the single human nerve most subject to anatomic variations. Figure #1shows the dermatome of LFCN. The nerve is small and mostly invisible under ultrasound scanning. For nerve block success, drug must be injected into four fascial compartments, each of which a variant nerve type may pass through in different individuals. 2. ANATOMY The lateral femoral cutaneous nerve is a sensory nerve supplying the skin on the lateral aspect of the thigh. That sensory area nearly reaches the thigh posterior midline and the thigh anterior midline. Its superior limit passes over the greater trochanter and its inferior limit nearly reaches the height of the patella. The typical LCNT, in 60% of patients, is a branch of the lumbar plexus deriving from the dorsal divisions of nerve roots L2 and L3. The LFCN forms within the psoas muscle, and exits the pelvis medial to the anterior superior iliac spine (ASIS) and under the inguinal ligament. It then passes over the sartorius muscle, under fascia lata, before branching into its final Figure 1. Classic dermatomal distribution of the divisions. In forty percent of patients the LFCN lateral femoral cutaneous nerve (LFCN), derived has completely different anatomy, but from Sobotta. fortunately the nerve always passes in proximity to the proximal sartorius muscle.

  • Study Protocol and Statistical Analysis Plan
    The University of Texas Southwestern Medical Center at Dallas Institutional Review Board PROJECT SUMMARY Study Title: Ultrasound-guided fascia iliaca compartment block versus periarticular infiltration for pain management after total hip arthroplasty: a randomized controlled trial Principal Investigator: Irina Gasanova, MD Sponsor/Funding Source: Department of Anesthesiology and Pain Management, UT Southwestern Medical School IRB Number: STU 122015-022 NCT Number: NCT02658240 Date of Document: 01 April 2016 Page 1 of 7 Purpose: In this randomized, controlled, observer-blinded study we plan to evaluate ultrasound-guided fascia iliaca compartment block with ropivacaine and periarticular infiltration with ropivacaine for postoperative pain management after total hip arthroplasty (THA). Background: Despite substantial advances in our understanding of the pathophysiology of pain and availability of newer analgesic techniques, postoperative pain is not always effectively treated (1). Optimal pain management technique balances pain relief with concerns about safety and adverse effects associated with analgesic techniques. Currently, postoperative pain is commonly treated with systemic opioids, which are associated with numerous adverse effects including nausea and vomiting, dizziness, drowsiness, pruritus, urinary retention, and respiratory depression (2). Use of regional and local anesthesia has been shown to reduce opioid requirements and opioid-related side effects. Therefore, their use has been emphasized (3, 4, 5, 6). Fascia Iliaca compartment block (FICB) is a field block that blocks the nerves from the lumbar plexus supplying the thigh (i.e., lateral femoral cutaneous femoral and obturator nerves). The obturator nerve is sometimes involved in the FICB but probably plays little role in postoperative pain relief for most surgeries of the hip and proximal femur.

Patel Nibha1 and SS. Pancholi2* 1Department of Pharmaceutics, BITS Institute of Pharmacy, Gujarat Technological university, Varnama, Vadodara, Gujarat, India 2BITS Institute of Pharmacy, Gujarat Technological University, Varnama, Vadodara, Gujarat, India. __________________________________________________________________________________ ABSTRACT Oral mucosal drug delivery is an alternative and promising method of systemic drug delivery which offers several advantages. Sublingual literally meaning is ''under the tongue'', administrating substance via mouth in such a way that the substance is rapidly absorbed via blood vessels under tongue. Sublingual route offers advantages such as bypasses hepatic first pass metabolic process which gives better bioavailability, rapid onset of action, patient compliance , self-medicated. Dysphagia (difficulty in swallowing) is common among in all ages of people and more in pediatric, geriatric, psychiatric patients. In terms of permeability, sublingual area of oral cavity is more permeable than buccal area which is in turn is more permeable than palatal area. Different techniques are used to formulate the sublingual dosage forms. Sublingual drug administration is applied in field of cardiovascular drugs, steroids, enzymes and some barbiturates. This review highlights advantages, disadvantages, different sublingual formulation such as tablets and films, evaluation. Key Words: Sublingual delivery, techniques, improved bioavailability, evaluation. INTRODUCTION and direct access to systemic circulation, the oral Drugs have been applied to the mucosa for topical mucosal route is suitable for drugs, which are application for many years. However, recently susceptible to acid hydrolysis in the stomach or there has been interest in exploiting the oral cavity which are extensively metabolized in the liver.

  • Vaccine Administration Joellen Wolicki, BSN, RN and Elaine Miller, RN, BSN, MPH
    Vaccine Administration JoEllen Wolicki, BSN, RN and Elaine Miller, RN, BSN, MPH This chapter summarizes best practices related to vaccine administration, a key factor in ensuring vaccination is as safe NOTES and effective as possible. Administration involves a series of actions: assessing patient vaccination status and determining needed vaccines, screening for contraindications and precautions, educating patients, preparing and administering vaccines properly, and documenting the vaccines administered. Professional standards for medication administration, manufacturer instructions, and organizational policies and procedures should always be followed when applicable. 6 Staff Training and Education Policies should be in place to validate health care professionals’ knowledge of, and skills in, vaccine administration. All health care professionals should receive comprehensive, competency- based training before administering vaccines. Training, including an observation component, should be integrated into health care professionals’ education programs including orientation for new staff and annual continuing education requirements for all staff. In addition, health care professionals should receive educational updates as needed, such as when vaccine administration recommendations are updated or when new vaccines are added to the facility’s inventory. Training should also be offered to temporary staff who may be filling in on days when the facility is short-staffed or helping during peak periods of vaccine administration such as influenza season. Once initial training has been completed, accountability checks should be in place to ensure staff follow all vaccine administration policies and procedures. Before Administering Vaccine Health care professionals should be knowledgeable about appropriate techniques to prepare and care for patients when administering vaccines. Assess for Needed Vaccines The patient’s immunization status should be reviewed at every health care visit.

  • The Development of an Intramuscular Injection Simulation for Nursing Students
    Open Access Technical Report DOI: 10.7759/cureus.12366 The Development of an Intramuscular Injection Simulation for Nursing Students Julia Micallef 1 , Artur Arutiunian 1 , Adam Dubrowski 1 1. Health Sciences, Ontario Tech University, Oshawa, CAN Corresponding author: Adam Dubrowski, [email protected] Abstract Intramuscular (IM) injections are preferred over subcutaneous injections for administering medicine such as epinephrine and vaccines as the muscle tissue contains an increased vascular supply that provides ideal absorption of the drug being administered. However, administering an IM injection requires clinical judgment when choosing the injection site, understanding the relevant anatomy and physiology as well as the principles and techniques for administering an IM injection. Therefore, it is essential to learn and perform IM injections using injection simulators to practice the skill before administering to a real patient. Current IM injection simulators either favor realism at the expense of standardization or are expensive but do not provide a realistic experience. Therefore, it is imperative to develop an inexpensive but realistic intramuscular injection simulator that can be used to train nursing students so that they can be prepared for when they enter the clinical setting. This technical report aims to provide an overview of the development of an inexpensive and realistic deltoid simulator geared to teach nursing students the skill of IM injections. After development, the IM simulators were tested and validated by practicing nurses. An 18-item survey was administered to the nurses, and results indicated positive feedback about the realism of the simulator, in comparison to previous models used, such as the Wallcur® PRACTI-Injecta Pads (Wallcur LLC, San Diego, CA).

Pylypiv Thesis Approved: Accepted: Advisor Dean of the College of Engineering Dr. Rebecca Kuntz Willits Dr. Donald Visco Committee Member Executive Dean of the Graduate School Dr. Matthew Becker Dr. Chand Midha Committee Member Date Dr. Ge Zhang Biomedical Engineering Department Chair Dr. Brian Davis ii ABSTRACT Electrical stimulation (ES) has previously demonstrated promising effects on peripheral nerve repair through enhanced neurite growth in vitro and shortened recovery time in vivo. In this study, we aimed to evaluate the effect of intraoperative short term ES on a clinically relevant isograft-repair model of a rodent peripheral nerve. In our model, an isograft was used to repair a 13 mm sciatic nerve gap-defect in adult male rats. Intraoperative ES was applied for 10 min at 24 V/m-DC to the experimental group and no stimulation was applied to the control group. We evaluated biweekly functional recovery over 12 weeks for motor function, using the sciatic functional index and external postural thrust. Sensory function was evaluated using a thermal stimulus. Motor nerves are more heavily myelinated and regenerate more quickly, while sensory nerves are less myelinated and have a slower recovery time. Structural repair outcomes were evaluated through histological examination of the sciatic nerves and gastrocnemius muscles at 6 and 12-week time points.

  • The Digestive System
    69 chapter four THE DIGESTIVE SYSTEM THE DIGESTIVE SYSTEM The digestive system is structurally divided into two main parts: a long, winding tube that carries food through its length, and a series of supportive organs outside of the tube. The long tube is called the gastrointestinal (GI) tract. The GI tract extends from the mouth to the anus, and consists of the mouth, or oral cavity, the pharynx, the esophagus, the stomach, the small intestine, and the large intes- tine. It is here that the functions of mechanical digestion, chemical digestion, absorption of nutrients and water, and release of solid waste material take place. The supportive organs that lie outside the GI tract are known as accessory organs, and include the teeth, salivary glands, liver, gallbladder, and pancreas. Because most organs of the digestive system lie within body cavities, you will perform a dissection procedure that exposes the cavities before you begin identifying individual organs. You will also observe the cavities and their associated membranes before proceeding with your study of the digestive system. EXPOSING THE BODY CAVITIES should feel like the wall of a stretched balloon. With your skinned cat on its dorsal side, examine the cutting lines shown in Figure 4.1 and plan 2.
