Topical Outline and Schedule
DATE WEEK 1 SPECIFIC Describe the course. OBJECTIVES Discuss the library and library resources. Define these four basic terms: drug, pharmacology, clinical pharmacology, and therapeutics. List the three most important properties of an ideal drug as well as several other important properties, and explain why many drugs do not have these traits. Differentiate between therapeutic effect and maximum benefit with minimum harm. Identify factors in determining the intensity of drug responses. Utilize mobile applications to access information about medications. Relate the five steps of the nursing process to the administration of medications. List the Five Rights of Drug Administration and the patient’s rights regarding medications administered by healthcare providers. Discuss the purpose of preadministration assessment. Discuss the analysis of the data and development of nursing diagnoses to (1) judge the appropriateness of the prescribed regimen, (2) identify health problems the drug might cause, and (3) determine the patient’s capacity for self-care. Develop a plan of care that does the following: (1) defines the goal of drug therapy; (2) is prioritized based on the drug under consideration 3 | P a g e NURSING DEPARTMENT
and the patient’s unique characteristics; (3) identifies nursing interventions based on [a] drug administration, [b] interventions to enhance therapeutic effects, [c] interventions to minimize adverse effects and interactions, and [d] patient education; and (4) establishes objective criteria for evaluation. Discuss implementation of the care plan in drug therapy. Understand how to record nursing interventions and observations of the patient’s responses to drug therapy. Describe the five diverse and important topics in pharmacology: (1) landmark drug legislation in the United States that reflects the evolution in our national viewpoint on regulation of the pharmaceutical industry; (2) new drug development (e.g., the cost of more than $800 million to develop a new drug); (3) the nuances of formulating drug names; (4) over-the-counter drugs; and (5) sources of drug information. All of these topics have significant implications for pharmacology and nursing care. Such information requires the profession of nursing and individual nurses to participate in continuing education in pharmacology and its administration. Discuss Phases I, II, III, and IV of the clinical testing of new drugs. Discuss the ethical and legal implications for the different phases of clinical testing. Phase I studies involve the use of healthy human volunteers to test the drugs. In Phases II and III, drugs are tested in patients. Upon completion of Phase III, the drug manufacturer applies to the FDA for conditional approval. Explain the purpose of Phase IV clinical studies after regulatory (i.e., FDA) approval. Discuss the important information that can be gained from Phase IV (postmarketing surveillance) of clinical drug testing and explain the roles and responsibilities of the nurse, nurse practitioner, and physician in gathering and reporting new data. Discuss chemical, generic, and proprietary (trade or brand) names of drugs and explain the benefits, if any, of generic drugs over brand- name drugs. Identify appropriate resources for pharmacology information and patient care and discuss why, in particular, some may be more suitable than others for a specific purpose (e.g., a specific type of information that is sought). Perform basic arithmetic calculations, including addition, subtraction, multiplication, and division with positive and negative numbers. Perform calculations incorporating rules for rounding numbers to achieve the correct result. Convert among fractions, decimal form, and percentage form. Convert between metric units. Convert between metric and nonmetric units. Perform ration and proportion calculations.

Discuss the advantages and disadvantages of the various techniques of drug administration as they relate to pharmacokinetics, noting especially any barriers to absorption associated with intravenous, intramuscular, and oral administration. Also compare oral 5 | P a g e NURSING DEPARTMENT
administration with parenteral administration. Describe blood flow to tissues, the ability of a drug to exit the vascular system, and the ability of a drug to enter cells, and then discuss the characteristics of drug molecules that can alter these processes. Describe the ultimate “goal” of drug metabolism, also known as biotransformation. Discuss the general processes involved in drug metabolism and identify the major or vital organs in which most drug metabolism occurs. Discuss special considerations in drug metabolism. Discuss the importance of excretion of a drug from the body and some of the routes by which the drug may be excreted. Discuss the importance of understanding the time course of drug responses (plasma drug levels, single-dose time course, drug half-life, and drug levels produced with repeated doses). Explain why clinicians often monitor plasma drug levels, and describe how these levels are regulated to prevent drug toxicity. Identify the two factors that largely determine the duration of a single-dose time course, and compare drugs with short half-lives versus those with long half-lives. Discuss the negative effects of repeated drug doses. Discuss the consequences of drug blood levels that fluctuate considerably or erratically between doses, and describe how nurses identify such fluctuations. Discuss measures that traditionally have been taken to minimize fluctuation. Define pharmacodynamics and its relationship to the action of drugs on the body. Discuss dose-response relationships (e.g., basic features of the dose- response relationships, maximal efficacy, and relative potency), the effects drugs can produce, and the amount of drug needed to elicit an effect. Discuss properties of drug-receptor interactions (e.g., drug receptors, four primary receptor families, receptors and selectivity for drug action, theories of drug-receptor interaction, agonists, antagonists, partial agonists, and regulation of receptor sensitivity). Describe how receptors function in the responses to many drugs and physiologic processes, such as the activity of the respiratory and gastrointestinal systems. Differentiate drugs that are agonists, partial agonists, or antagonists. List the four primary families of receptors. Discuss “receptorless drugs” (e.g., antacids, antiseptics, saline laxatives, chelating agents, and so on). Discuss interpatient variability in drug responses and describe how to measure variability. Define the ED50 and the LD50. Discuss the concept of a drug’s therapeutic index and its application and benefits to clinical practice, such as the relationships between the doses of a drug and whether its effects are subtherapeutic (inadequate response), therapeutic (desired response), or toxic (adverse effects 6 | P a g e NURSING DEPARTMENT
related to excessive dosage). Discuss the role of the nurse in achieving therapeutic responses of selected medications. Implement effective communication tools to advocate for patients in the clinical setting. Identify electronic resources available for determining action, side effects, therapeutic index, and anticipated effects of drugs. Discuss the consequences of drug-drug interactions, the basic mechanisms of drug-drug interactions, and the critical steps in minimizing adverse drug-drug interactions. Focus on the liver as an example of a drug-metabolizing system and explain why it is such a crucial organ in many drug-drug interactions. Discuss the effect of food on drug absorption, on drug metabolism (e.g., grapefruit juice), and on drug toxicity and action, as well as the timing of drug administration with respect to meals. Give examples of inhibitory interaction of drugs that can produce dangerous effects and those that are beneficial. Discuss the mechanisms and clinical consequences of drug-herb interactions and drug-food interactions. Focus on ways to minimize adverse drug-drug interactions and drug-food interactions. Include in the discussion the effect of food on drug absorption and metabolism, drug toxicity, drug action, and the timing of drug administration with respect to meals. Discuss the dilemma that increased consumption of herbal supplements has created in the pharmaceutical environment because of these supplements’ potential for common and significant interactions with prescription and over-the-counter drugs. Design a plan of care for patients who are prescribed medications that have known drug-drug or drug-food interactions. Identify electronic resources available for determining action, side effects, therapeutic index, and anticipated effects of drugs. Discuss the scope of the problem of adverse drug reactions. Discuss definitions for adverse drug reactions (e.g., side effect, toxicity, allergic reaction, idiosyncratic effect, iatrogenic disease, physical dependence, carcinogenic effect, and teratogenic effect). Discuss organ-specific toxicity. Focus on the liver as a drug- metabolizing system and explain why it is such a crucial participant in organ-specific toxicity with drugs. Discuss how and why adverse drug reactions occur, given that for a prescription drug to be approved for use, it must have demonstrated and been documented for safety, and also given the explicit printed information provided about such facts as doses, routes, interactions, and so on. Discuss adverse reactions to new drugs and the importance of being alert for unusual responses when giving new drugs. Also point out the
7 | P a g e NURSING DEPARTMENT
importance of informing other nurses where to report unknown adverse effects of a new drug and of accessing a website where information on adverse effects can be reported. Discuss measures that can be used to minimize adverse drug events. Define medication errors and explain what constitutes an error, as well as who makes errors. Discuss types of medication errors, causes of medication errors, ways to reduce medication errors, and ways to report medication errors. Discuss the significance of body weight and composition, focusing on the effect of weight and the requirement for larger doses of a drug to obtain a therapeutic effect because of an increase in tissues to perfuse (percentage of body fat) and an increase in receptor sites in some reactive tissue. Discuss age as a factor in medication administration, noting that drug sensitivity varies with age and that infants are especially sensitive to drugs, as are the elderly. Discuss the effects of kidney disease, liver disease, acid-base imbalance, and altered electrolyte status on drug responses. Discuss the three categories of drug tolerance: pharmacodynamic tolerance, metabolic tolerance, and tachyphylaxis. Define placebo effects and explain the beneficial and negative effects. Discuss bioavailability and other causes of variable absorption. Explain why differences in bioavailability are a significant concern with drugs that have a narrow therapeutic index. Discuss common mechanisms by which genetic differences modify drug responses (for example, altered drug-metabolizing enzymes, altered drug targets). Discuss three gender-related differences that can occur in response to administration of the same drug. Discuss two primary determinants of race-related drug responses. Discuss factors that may result in the patient’s failure to take medications as prescribed. Discuss drug interaction as a source of variability. Discuss the effects of diet on drug responses.

Discuss renal excretion and compare the drug-excreting capacity of a newborn with that of a 1-year-old infant. Discuss the pharmacokinetics of children 1 year old or older. Discuss reasons pediatric patients are subject to adverse drug reactions when drug levels rise too high. Discuss dosage determination, noting that pediatric doses have been established for some drugs but not for others and, therefore, for drugs that do not have established pediatric doses, the doses can be extrapolated from adult doses. Discuss methods that are effective at and critical to promoting parent and guardian adherence to pediatric drug regimens. Summarize some of the main reasons a very young patient may be considered “highly” sensitive to drugs, considering both pharmacokinetic factors (absorption, distribution, and elimination) and pharmacodynamic factors that affect this apparent sensitivity.

Homework: Chapter readings: Chapters 12, 13, 14, 15, DATE WEEK 4 SPECIFIC At the end of this lesson, you will be able to: OBJECTIVES Discuss the reason most neuropharmacologic agents act by altering synaptic transmission instead of altering axonal conduction. Describe the general steps involved in neurotransmission (synaptic transmission) and axonal conduction. State the elements or processes that need to occur, regardless of the site in the nervous system, for synaptic transmission to work. Discuss specific ways in which drugs can alter the steps of synaptic transmission. Discuss the relationship between multiple receptor types and selective drug action. Identify the two major divisions of the peripheral nervous system. Differentiate between the somatic (motor) nervous system and the sympathetic and parasympathetic branches of the autonomic nervous system in terms of (1) overall anatomic organization (numbers, types of nerves); (2) neurotransmitters made and released by the nerves; and (3) the targets (effectors) of the neurotransmitters’ actions, whether those structures are innervated by one or both branches of the autonomic nervous system, and the effects of activating those structures. Describe the differences distinguishing the four main subtypes of adrenergic receptors – alpha1, alpha2, beta1, and beta2 – in terms of
11 | P a g e NURSING DEPARTMENT
where (on what structures) they are found and the responses their activation causes. Describe the differences between the two main subtypes of cholinergic receptors – nicotinic (both nicotinicN and nicotinicM) and muscarinic – in terms of where (on what structures) they are found and the responses their activation causes. Identify the basic processes by which the main autonomic nervous system neurotransmitters are terminated physiologically. State the responses that a muscarinic agonist would be expected to cause through direct activation of muscarinic cholinergic receptors (consider bethanechol). The student should focus on the main “targets” of parasympathetic nervous system activity: eyes, respiratory system, heart and blood vessels, gastrointestinal (GI) and urinary tracts, and the secretory activity of exocrine glands (for example, lacrimal, mucous, and so on). List cholinergic responses not normally caused when the usual therapeutic doses of a muscarinic agonist are administered and explain why these effects do not occur. State the main side effects of a muscarinic agonist (for example, bethanechol) and related precautions or contraindications to its use. Give several reasons why acetylcholine itself is not used to produce selective muscarinic-activating effects and why other drugs generally are chosen. Describe the signs and symptoms of muscarinic antagonist (for example, atropine) “poisoning,” how it is managed, and how and where such a syndrome can occur without the patient receiving any therapeutic product. Describe the main effects of cholinesterase inhibitors on structures controlled by the autonomic nervous system and on skeletal muscle, and state the general mechanism by which these effects occur. Compare and contrast the effects of the cholinesterase inhibitors with those of bethanechol, which was described as the most representative muscarinic agonist (see Chapter 14). State the main clinical uses of cholinesterase inhibitors and precautions for and contraindications to their use. Recognize the meaning and importance of the term quaternary when applied to the structure of a drug; compare and contrast the actions of neostigmine and physostigmine in the context of whether they are quaternary compounds. Compare and contrast the cholinergic crisis and the myasthenic crisis in a hypothetical patient with myasthenia gravis; describe simple assessments that would help distinguish the two conditions; and state the rationale for using cholinesterase inhibitors to help confirm the diagnosis. Describe the signs and symptoms associated with cholinesterase inhibitor overdose and the general approaches to managing it.

Describe the anatomy of the somatic nervous system, the key transmitter and receptor type involved in skeletal muscle activation, and the physiologic consequences of activating those cell receptors. Compare and contrast the mechanisms of action of nondepolarizing and depolarizing neuromuscular blocking agents and state how these 13 | P a g e NURSING DEPARTMENT
actions influence the use of one class rather than the other in specified clinical situations. Identify three specific uses for neuromuscular blocking agents and describe the monitoring and other measures necessary with their use. Discuss the main risks and main cause of death with neuromuscular blocking agents and describe steps to manage potentially fatal responses. Identify the class of drugs used to reverse the effects of nondepolarizing neuromuscular blockers and describe the mechanism by which they cause that reversal. Also explain why pharmacologic reversal is not used when succinylcholine is the neuromuscular blocker. Describe the etiology, signs, and symptoms of malignant hyperthermia; the drugs associated with a high risk for that condition; and interventions to be implemented should it develop. Discuss the rationale for the limited applications of mecamylamine. Recall (for example, from Chapter 13) the sites (effectors) of alpha1-, beta1-, and beta2-adrenergic receptors and state the expected responses from their activation by a suitable agonist. Classify the following agonists in terms of the adrenergic receptors they activate and the responses they cause as a result of direct receptor activation: (1) epinephrine, (2) norepinephrine, (3) phenylephrine, (4) isoproterenol, (5) terbutaline, (6) dobutamine. Explain the difference between direct cardiac (beta1) effects of adrenergic agonists and reflex (baroreceptor reflex–mediated) effects of those same drugs, using norepinephrine, phenylephrine, and isoproterenol as examples. Explain how each of the following affects structures controlled by the sympathetic nervous system, comparing how they work with how a direct-acting agonist such as epinephrine works, and state one or more clinical uses for each: (1) ephedrine, (2) amphetamines, (3) cocaine, (4) monoamine oxidase (MAO) inhibitors Identify the desired effects when a therapeutic dose of epinephrine is given for anaphylaxis and explain the actions of the drug that earn it the label “drug of choice” for anaphylaxis. Identify individuals who should carry an EpiPen, when they should use it, how dosage should be calculated, and how it should be stored and replaced. Explain the self-injection procedure for the EpiPen. Summarize the main adrenergic receptor subtypes that mediate the ocular, cardiovascular, pulmonary, and uterine responses to sympathetic nervous system activation. Describe the main direct and indirect effects of alpha- and beta- adrenergic blockers (antagonists) on the structures listed in the preceding objective and on stated sympathetic/adrenergic responses. For each effect, the student should be able to state any applicable
14 | P a g e NURSING DEPARTMENT
precautions or contraindications to the use of such antagonists and explain the potential outcome if a stated blocker is administered to a patient for whom the antagonist ought not to be used. Describe the adverse effects of alpha blockade and compare them with the adverse effects of beta blockade. Describe the physiologic changes that affect blood pressure and other aspects of cardiovascular function as the patient goes from the supine to the standing position; also, explain the impact of alpha- and beta- adrenergic blockers on those compensatory processes. Explain the practical clinical implications of classifying some adrenergic blockers as “cardioselective” and others as having intrinsic sympathomimetic activity. Describe when and why they may be suitable (or potentially better) alternatives to nonselective beta blockers (for example, propranolol) overall, particularly for patients who may experience adverse responses to the nonselective blockers. Summarize the main mechanisms of action of reserpine, guanethidine, and methyldopa (or clonidine). Compare and contrast the general sites and mechanisms of action of reserpine, clonidine, and methyldopa with those of drugs that block adrenergic receptors (for example, propranolol and phentolamine). Explain the factors that lead to and the characteristics of the “rebound” phenomenon associated with sudden discontinuation of clonidine. Use the effects of the drugs described in this chapter to predict how responses to the main classes of adrenergic agonists (see Chapter 17) would be affected.

Homework: Chapter readings: Chapters 20, 21, 22, 23, 24, 25 DATE WEEK 6 SPECIFIC At the end of this lesson, you will be able to: OBJECTIVES Identify the main neurotransmitters of the central nervous system (CNS) and summarize some of their main physiologic effects. Discuss the significance of the blood-brain barrier in allowing or preventing the effects of drugs in general. Describe how, in many cases, control of key activities in the CNS involves more than one neural pathway, each with its own neurotransmitter and set of receptors. This is generally important for understanding much of the specific information presented in later chapters in this unit. Explain the interrelationships between the central nervous system (CNS) activities of dopamine and acetylcholine as they affect the signs and symptoms of Parkinsonism and as they relate to the general biochemical approach to correcting neurotransmitter imbalances with anti-Parkinsonian drugs. Discuss the drug treatment for Parkinson’s disease (PD), and discuss the current consensus on which agent or agents are recommended for initiating therapy in most patients with PD. Succinctly summarize the main anti-Parkinsonian mechanisms of action of levodopa, carbidopa, pramipexole, ropinirole, apomorphine, bromocriptine, amantadine, entacapone, tolcapone, and selegiline. Also, summarize the main adverse responses elicited by each of these drugs. Summarize the main neural pathologic changes involved in the etiology of Alzheimer’s disease (AD) (for example, define neuritic plaques and neurofibrillary tangles and explain how they form) and describe the main neurotransmitter “deficiency” that seems to account for most of the signs and symptoms. Summarize the main signs and symptoms of AD and the main risk factors for its development. Identify acetylcholinesterase inhibitors as the current main class of drugs for managing AD. State the main mechanism by which these drugs seem to confer some symptom relief in AD and summarize whether they seem to have short- or long-term benefit, providing symptomatic relief or a true cure. Donepezil should be used as the example drug. 16 | P a g e NURSING DEPARTMENT
State the main properties of donepezil that make it a good first-choice agent for AD in most cases. Also, summarize one or two key reasons tacrine is not a preferred agent. Describe the therapeutic effects and mechanism of action of memantine [Namenda]. Comment on the status of vitamin E and selegiline, nonsteroidal antiinflammatory drugs (NSAIDs), estrogen, and ginkgo biloba as agents that might relieve, delay the progression of, or protect against AD. Identify the primary pathology of multiple sclerosis (MS), including how inflammation occurs, what initiates the autoimmune process, what happens when an acute attack is over, and whether MS injures the myelin sheath of peripheral neurons. Describe the signs and symptoms of MS, including a description of the diagnostic criteria and the diagnostic tools that can help confirm a suspected diagnosis of MS. Describe the four subtypes of MS (relapsing-remitting, secondary progressive, primary progressive, and progressive-relapsing) and comment on the symptom patterns that characterize each subtype. Describe the mechanism of action, therapeutic use, and adverse effects of immunomodulators and immunosuppressants. Discuss medications available for symptom management of bladder and bowel dysfunction, depression, fatigue, spasticity, sexual dysfunction, neuropathic pain, ataxia and tremor, and cognitive dysfunction. Differentiate between seizure and convulsion and between partial (focal) and generalized seizures. Describe how seizures are initiated and generated. State and describe three cellular mechanisms by which antiepileptic drugs act. Describe the general goals of the treatment of epilepsy and some of the problems commonly encountered in reaching them. While considering the problems, articulate social and occupational factors, not just the pharmacologic factors. Discuss important considerations related to selecting an antiepileptic drug, monitoring its effectiveness (or lack thereof), and recognizing side effects and how to deal with them. State the most common reason for “therapeutic failure” of anticonvulsant drugs and describe steps that might be taken to reduce the problem. Summarize the likely problems for which the patient must be assessed and treated when the decision is made to discontinue one anticonvulsant drug and switch to another. Summarize the likely problems for which the patient must be assessed and treated when a second agent must be added to a treatment plan that

The following strategies may be used in this class: 42 | P a g e NURSING DEPARTMENT
1. Threaded Discussions 2. Case studies 3. Quizzes 4. Readings 5. Exams
Academic Honesty: When learners fail to complete their own work, they are cheating themselves out of their education and are committing plagiarism. Plagiarism, or failing to meet the academic honesty policy, will result in disciplinary actions by the institution.
Plagiarism is dishonest behavior that will not be tolerated. A student will not receive credit if found to have plagiarized his/her work and may result in suspension or dismissal from the school. Follow the link for examples of plagiarism: http://examples.yourdictionary.com/examples/examples-of-plagiarism.html APA Format: All of your writing must be done following APA format. For more information regarding this format, go to Purdue Owl or follow this link:https://owl.english.purdue.edu/owl/resource/560/01/
Late work & Educational Responsibility: All assignments must be completed by the last day of the schedule unless an alternate due date has been previously approved by your instructor or documentation has been provided regarding extreme circumstances. It is the learner's responsibility to communicate with the instructor about extreme circumstances or ask questions concerning the assignment and their due dates.
Threaded discussions: Students are to respond to the instructor’s weekly discussion post by Wednesday at 1159 PM (EST). The responses must be substantial (at least 125 words in length using correct grammar).
These are intended to stimulate discussion and re-enforce course content. The student must also respond to two other student posts by Friday at 11:59 PM (EST). Please refer to the assignment calendar for assignment due dates.
ASSESSMENT TESTING FOR NURSING PROGRAM REQUIREMENT: As part of certain nursing courses, students are required to take third-party computerized assessments, These assessments are intended to provide students with the tools they need to be successful in the Nursing program and on the NCLEX; as well as. Increase confidence and familiarity with computerized testing, The assessments typically include various types of formats, including multiple choice items, multiple response items, fill-in-the-blank items, drag- and drop items, hot spots items, chart/exhibit items, and other items,. The assessments help identify deficit areas and provide students opportunities to practice and learn. Each assessment can represent up to the percent (10%) of a student’s course grade. Failure to achieve the minimum assessment score may result in a loss of points on an examination, or required remediation or retesting (as outlined in the course syllabus). Students who do not successfully complete the remediation or retest associated with an assessment examination (as outlined in the course syllabus) may receive an incomplete in a course and may be required to repeat the course
43 | P a g e NURSING DEPARTMENT
in its entirety. An incomplete due to failure to successfully complete the assessment testing remediation or successfully retest is considered a failure for the course.

Assessment Criteria and Methods of Evaluating Students
90 – 100% A 80 – 89% B 75 – 79% C < 75% F
Do not count on a curve!
Generally, the grades “A” through “C-” are considered passing grades. Grades "W" and "I" indicate that no grades were earned for the course. A "W" grade indicates that the student withdrew from the course. An "I" grade indicates that the student was passing the course, but failed to complete all the required course work. The instructor, in his/her discretion may grant an "I" grade instead of an "F", pending completion of the course work by the student within a specified time arranged by the instructor and told to the student. It is the student's responsibility to follow-up with the instructor to complete the course work. If the course work is not completed by the arranged time, the “I” grade becomes an “F".
