D116 prepares nurse practitioner students to prescribe and monitor medication safely, building directly on the disease mechanisms studied in D115.
WGU's MSN Family Nurse Practitioner program guide says the course develops competencies for prescribing and monitoring medication safely and effectively, applying pharmacotherapeutics in primary care on the basis of pharmacokinetics and pharmacodynamics.
Students learn to select the correct medication, explain the rationale to patients, families and other providers, and monitor patients to promote positive drug outcomes.
The challenge is volume and precision. Grouping drugs by class and mechanism is far more effective than memorizing individual names.

Key Concepts Explained
Pharmacokinetics
Pharmacokinetics is what the body does to a drug: absorption, distribution, metabolism and excretion. Changes in any step, such as reduced kidney function, alter drug levels and may require dose adjustment.
Example: A drug with a half-life of 6 hours, given regularly, reaches steady state after about four to five half-lives, roughly 24 to 30 hours. That explains why its full effect is not judged on day one, and why a loading dose is sometimes used when a faster effect is needed.
Pharmacodynamics
Pharmacodynamics is what the drug does to the body: receptor binding, mechanism of action and dose-response. Agonists activate receptors; antagonists block them.
Drug Interactions
Interactions may be pharmacokinetic (one drug changes another's levels, often through liver enzymes such as cytochrome P450) or pharmacodynamic (two drugs with additive or opposing effects).
Example: A patient taking warfarin is prescribed an antibiotic known to raise INR. A safe plan considers an alternative antibiotic or closer INR monitoring, and the rationale is explained to the patient: "This antibiotic can make your blood thinner work more strongly, so we will check your blood test sooner."
Medication Safety in Transitions of Care
One competency focuses on pharmacological changes as patients move between hospital, home, rehabilitation and primary care. These moments carry a high risk of errors.
- Medication reconciliation: compare the full list before and after the transition, including over-the-counter products and supplements.
- Clarify changes: note which drugs were started, stopped or changed, and why.
- Educate: give the patient and family a clear, updated list in plain language.
- Follow up: plan monitoring for new drugs with narrow therapeutic ranges.
Older adults with multiple conditions are especially at risk, which links this competency to geriatric care in D120.
Typical Tasks and How to Approach Them
| Task type | What it tests | How to approach it |
|---|---|---|
| Drug-class questions | Mechanism, uses, adverse effects | Learn the class pattern, then the exceptions |
| Case-based prescribing | Selecting and justifying therapy | Consider diagnosis, patient factors, interactions and guidelines |
| Patient explanation | Communicating rationale | State purpose, key side effects and monitoring simply |
A Prescribing Decision in Five Questions
WGU's description stresses selecting the correct medication and explaining the rationale. A short, repeatable checklist keeps case answers complete:
- What is the diagnosis and goal? Cure, symptom control or prevention.
- What does current guidance recommend first-line? Name the class and the reason.
- Is this patient different? Age, pregnancy, kidney or liver function, allergies and other medications.
- How will you monitor it? Labs, symptoms, side effects and a review date.
- How will you explain it? Purpose, how to take it and when to seek help.
Example: For uncomplicated cystitis in a non-pregnant adult, a strong answer names a guideline-recommended first-line option, checks allergy history and kidney function, notes local resistance patterns, and tells the patient to return if fever or flank pain develops.
Where Students Get Stuck
- Memorizing names. Learn suffixes and classes: -olol for beta blockers, -pril for ACE inhibitors, -statin for HMG-CoA reductase inhibitors.
- Special populations. Pregnancy, children, older adults and renal impairment change choices and doses.
- Monitoring. Know which drugs need lab checks and why.
- Linking to pathophysiology. Ask which mechanism from D115 each drug targets.
Study Tips for D116
- Build a table per system: class, mechanism, indications, key adverse effects, monitoring.
- Use reputable, current references and guidelines rather than memory alone.
- Practice explaining one drug a day in patient-friendly language.
- Review interactions for commonly prescribed primary care drugs.
How We Help with D116
Tell us which drug classes or competencies are difficult and send task instructions or practice material. A nursing tutor with graduate-level knowledge can prepare drug-class summaries, explain mechanisms and review written work for accuracy. Our material is educational and is not clinical prescribing advice.

Frequently Asked Questions
Evidence-based prescribing principles and pharmacology across the nervous, pulmonary, cardiovascular, gastrointestinal, endocrine and musculoskeletal systems, plus wellness, women's and men's health, infectious disease, allergy and transitions of care.
The FNP program guide we checked lists it at 4 competency units in the second term.
Pharmacokinetics is how the body handles a drug; pharmacodynamics is how the drug affects the body.
Yes. Understanding disease mechanisms makes drug mechanisms and choices much easier to follow.
