Principles of Pharmacotherapeutics & Prescribing
1. Which term describes the study of how the body affects a drug, including absorption, distribution, metabolism, and
excretion?
A. Pharmacokinetics
B. Pharmacodynamics
C. Pharmacogenomics
D. Pharmacoeconomics
Correct Answer: A. Pharmacokinetics
Rationale: Pharmacokinetics describes what the body does to a drug — its absorption, distribution, metabolism, and
excretion (ADME).
2. Which term describes the study of how a drug affects the body, including its mechanism of action and effects at the
receptor level?
A. Pharmacodynamics
B. Pharmacokinetics
C. Pharmacogenomics
D. Pharmacovigilance
Correct Answer: A. Pharmacodynamics
Rationale: Pharmacodynamics describes what the drug does to the body, including its mechanism of action and the
relationship between drug concentration and effect.
3. Pharmacogenomics is best defined as the study of:
A. How an individual's genetic makeup affects their response to medications
B. Only the economic cost-effectiveness of medications
C. Drug interactions with food exclusively
D. The physical properties of a drug formulation
Correct Answer: A. How an individual's genetic makeup affects their response to medications
Rationale: Pharmacogenomics examines how genetic variation among individuals influences drug metabolism, efficacy,
and risk of adverse effects, informing personalized prescribing decisions.
4. A patient who is a CYP2D6 "poor metabolizer" would be expected to have which effect when prescribed a medication
primarily metabolized by this enzyme?
A. Higher than expected serum drug levels and increased risk of toxicity at standard doses
B. Lower than expected serum drug levels and reduced efficacy at standard doses
C. No clinically significant effect on drug metabolism
D. Enhanced drug absorption in the gastrointestinal tract
Correct Answer: A. Higher than expected serum drug levels and increased risk of toxicity at standard doses
Rationale: Poor metabolizers have reduced enzymatic activity, leading to slower drug clearance, higher serum
concentrations, and increased risk of toxicity at standard doses for drugs metabolized by that pathway.
5. Which factor is most likely to significantly increase the free (unbound) fraction of a highly protein-bound medication?
A. Hypoalbuminemia
B. Elevated serum albumin
C. Increased renal clearance with no change in protein binding
D. Decreased hepatic blood flow alone
Correct Answer: A. Hypoalbuminemia
Rationale: Low albumin levels reduce available protein binding sites, increasing the free, pharmacologically active
fraction of highly protein-bound drugs and raising the risk of toxicity.
6. The nurse practitioner is prescribing a medication with a narrow therapeutic index. This requires which special
consideration?
A. Close monitoring of serum drug levels and clinical response
3
, NR565 Test Bank — Style Review (1st Ed., Demler) Practice
B. No monitoring is needed since dosing is standardized for all patients
C. Once-yearly monitoring only, regardless of dose changes
D. Discontinuation after the first dose regardless of response
Correct Answer: A. Close monitoring of serum drug levels and clinical response
Rationale: Narrow therapeutic index medications (e.g., warfarin, digoxin, lithium, phenytoin) require close monitoring
due to the small margin between therapeutic and toxic serum concentrations.
7. Which term describes an adverse reaction that occurs due to an interaction between two or more concurrently administered
medications?
A. Drug-drug interaction
B. Idiosyncratic reaction
C. Anaphylactoid reaction
D. Therapeutic index
Correct Answer: A. Drug-drug interaction
Rationale: A drug-drug interaction occurs when the effect of one medication is altered by the presence of another,
potentially increasing or decreasing efficacy or toxicity.
8. A patient taking a CYP450 3A4 inhibitor concurrently with a CYP3A4 substrate medication is at risk for:
A. Increased serum levels and potential toxicity of the substrate medication
B. Decreased serum levels and reduced efficacy of the substrate medication
C. No clinically significant interaction
D. Enhanced renal clearance of the substrate medication
Correct Answer: A. Increased serum levels and potential toxicity of the substrate medication
Rationale: CYP3A4 inhibitors slow the metabolism of substrate drugs, leading to increased serum concentrations and
potential toxicity.
9. Which prescribing principle reflects appropriate application of evidence-based practice in advanced practice nursing?
A. Integrating the best available research evidence, clinical expertise, and patient preferences into prescribing decisions
B. Prescribing based solely on personal past experience with no attention to current guidelines
C. Following pharmaceutical representative recommendations without independent evaluation
D. Prescribing the same regimen for all patients with a given diagnosis regardless of individual factors
Correct Answer: A. Integrating the best available research evidence, clinical expertise, and patient preferences
into prescribing decisions
Rationale: Evidence-based prescribing combines the best current research evidence, clinical expertise, and individual
patient preferences and circumstances to guide medication decisions.
10. The nurse practitioner is considering starting a new medication in an older adult patient. Which resource is specifically
designed to identify potentially inappropriate medications in this population?
A. The Beers Criteria
B. The Bishop Score
C. The Apgar Score
D. The CHA2DS2-VASc Score
Correct Answer: A. The Beers Criteria
Rationale: The Beers Criteria is an evidence-based, widely used list identifying medications that are potentially
inappropriate for use in older adults due to increased risk of adverse effects.
11. Which pregnancy-related prescribing consideration reflects current best practice, given the retirement of the FDA's letter
category system?
A. Reviewing detailed narrative risk summaries under the Pregnancy and Lactation Labeling Rule (PLLR) rather than
relying on a letter category alone
B. Continuing to rely exclusively on the FDA pregnancy letter categories (A, B, C, D, X)
C. Assuming all medications are safe in pregnancy unless specifically labeled otherwise
D. Avoiding all medication use during pregnancy regardless of maternal risk
