NURS 6521 Week 1 Discussion: Pharmacokinetics and Pharmacodynamics

As an advanced practice nurse assisting physicians in the diagnosis and treatment of disorders, it is important to not only understand the impact of disorders on the body, but also the impact of drug treatments on the body. The relationships between drugs and the body can be described by pharmacokinetics and pharmacodynamics. Pharmacokinetics describes what the body does to the drug through absorption, distribution, metabolism, and excretion, whereas pharmacodynamics describes what the drug does to the body. When selecting drugs and determining dosages for patients, it is essential to consider individual patient factors that might impact the patient’s pharmacokinetic and pharamcodynamic processes. These patient factors include genetics, gender, ethnicity, age, behavior (i.e., diet, nutrition, smoking, alcohol, illicit drug abuse), and/or pathophysiological changes due to disease. In this Discussion, you reflect on a case from your past clinical experiences and consider how a particular patient’s pharmacokinetic and pharmacodynamic processes altered his or her response to a drug.

To prepare for NURS 6521 Week 1 Discussion: Pharmacokinetics and Pharmacodynamics:

Review this week’s media presentation with Dr. Terry Buttaro, as well as Chapter 2 of the Arcangelo and Peterson text, and the Scott article in the Learning Resources. Consider the principles of pharmacokinetics and pharmacodynamics.

Reflect on your experiences, observations, and/or clinical practices from the last five years. Select a case from the last five years that involves a patient whose individual differences in pharmacokinetic and pharmacodynamic factors altered his or her anticipated response to a drug. When referring to your patient, make sure to use a pseudonym or other false form of identification. This is to ensure the privacy and protection of the patient.

Consider factors that might have influenced the patient’s pharmacokinetic and pharmacodynamic processes such as genetics (including pharmacogenetics), gender, ethnicity, age, behavior, and/or possible pathophysiological changes due to disease.

Think about a personalized plan of care based on these influencing factors and patient history in your case study.

With these thoughts in mind:

By Day 3

Post a description of the case you selected. Then, describe factors that might have influenced pharmacokinetic and pharmacodynamic processes of the patient from the case you selected. Finally, explain details of the personalized plan of care that you would develop based on influencing factors and patient history in your case.

By Day 6

Read a selection of your colleagues’ responses and respond to at least two of your colleagues on two different days by suggesting additional patient factors that might have interfered with the pharmacokinetic and pharmadynamic processes of the patients in their case studies. In addition, suggest how the personal care plan might change if the age of the patient were different and if the patient had a comorbid condition such as renal failure, heart failure, or liver failure.

Assignment: Ethical and Legal Implications of Prescribing Drugs

What type of drug should you prescribe based on your patient’s diagnosis? How much of the drug should the patient receive? How often should the drug be administered? When should the drug not be prescribed? Are there individual patient factors that could create complications when taking the drug? Should you be prescribing drugs to this patient?

These are some of the questions you might consider when selecting a treatment plan for a patient. As an advanced practice nurse prescribing drugs, you are held accountable for people’s lives on a daily basis. Patients and their families will often place trust in you because of your position. With this trust comes power and responsibility, as well as an ethical and legal obligation to “do no harm.” It is important that you are aware of current professional, legal, and ethical standards for advanced practice nurses with prescriptive authority. In this Discussion, you explore ethical and legal implications of scenarios and consider how to appropriately respond.

Scenario 1:

As a nurse practitioner, you prescribe medications for your patients. You make an error when prescribing medication to a 5-year-old patient. Rather than dosing him appropriately, you prescribe a dose suitable for an adult.

Scenario 2:

A friend calls and asks you to prescribe a medication for her. You have this autonomy, but you don’t have your friend’s medical history. You write the prescription anyway.

Scenario 3:

You see another nurse practitioner writing a prescription for her husband who is not a patient of the nurse practitioner. The prescription is for a narcotic. You can’t decide whether or not to report the incident.

Scenario 4:

During your lunch break at the hospital, you read a journal article on pharmacoeconomics. You think of a couple of patients who have recently mentioned their financial difficulties. You wonder if some of the expensive drugs you have prescribed are sufficiently managing the patients’ health conditions and improving their quality of life.

To Prepare

Review the Resources for this module and consider the legal and ethical implications of prescribing prescription drugs, disclosure, and nondisclosure.
Review the scenario assigned by your Instructor for this Assignment.
Search specific laws and standards for prescribing prescription drugs and for addressing medication errors for your state or region, and reflect on these as you review the scenario assigned by your Instructor.
Consider the ethical and legal implications of the scenario for all stakeholders involved, such as the prescriber, pharmacist, patient, and patient’s family.
Think about two strategies that you, as an advanced practice nurse, would use to guide your ethically and legally responsible decision-making in this scenario, including whether you would disclose any medication errors.

By Day 7 of Week 1

Write a 2- to 3-page paper that addresses the following:

Explain the ethical and legal implications of the scenario you selected on all stakeholders involved, such as the prescriber, pharmacist, patient, and patient’s family.
Describe strategies to address disclosure and nondisclosure as identified in the scenario you selected. Be sure to reference laws specific to your state.
Explain two strategies that you, as an advanced practice nurse, would use to guide your decision making in this scenario, including whether you would disclose your error. Be sure to justify your explanation.
Explain the process of writing prescriptions, including strategies to minimize medication errors.

Reminder: The College of Nursing requires that all papers submitted include a title page, introduction, summary, and references. The College of Nursing Writing Template with Instructions provided at the Walden Writing Center offers an example of those required elements (available at https://academicguides.waldenu.edu/writingcenter/templates/general#s-lg-box-20293632). All papers submitted must use this formatting.

In the next module, you will examine the impact of changes in pharmacokinetic and pharmacodynamic processes on patient drug therapy for cardiovascular disorders and the types of drugs prescribed to patients with respiratory disorders.

Looking Ahead: Week 2 Assignment

In Week 2, your Instructor will assign you a case study related to Assignment 1 by Day 1 of the week. Please make sure to review the “Course Announcements” area of the course to verify your assigned case study. Please plan ahead to ensure you have time to review your case study and Learning Resources in order to complete your Assignment on time.
