DESCRIPTION
This comprehensive practice examination is designed to help graduate nursing students
prepare for the NR 546 Midterm by reviewing major pharmacology concepts commonly
emphasized throughout advanced nursing curricula. The questions emphasize clinical
reasoning, medication safety, pharmacotherapeutic decision-making, interpretation of
patient scenarios, adverse drug reactions, evidence-based prescribing, and professional
judgment. Rather than focusing on memorization, the practice questions require
application of pharmacokinetic and pharmacodynamic principles to realistic patient
cases. This resource serves as a structured study aid based on widely taught graduate
pharmacology topics and commonly covered learning objectives. It is intended solely
for educational review and self-assessment and does not reproduce, represent, or
predict any actual examination content.
,QUESTION 1.
A 72-year-old patient with chronic kidney disease (eGFR 28 mL/min/1.73 m²)
develops a serious bacterial infection requiring antibiotic therapy. Which prescribing
approach best minimizes the risk of drug accumulation while maintaining therapeutic
efficacy?
A. Prescribe the standard adult dose regardless of renal function.
B. Select a renally eliminated medication and increase dosing frequency.
C. Adjust the dose or dosing interval based on renal function and therapeutic goals.
D. Delay antibiotic therapy until renal function improves.
🔴 Correct Answer: C. Adjust the dose or dosing interval based on renal function
and therapeutic goals.
🔵 Explanation: Renal impairment significantly alters elimination of many
medications, making individualized dose adjustment essential to balance efficacy and
toxicity. Standard dosing may lead to accumulation, whereas delaying treatment may
worsen infection. Increasing dosing frequency generally increases exposure rather than
reducing toxicity.
QUESTION 2.
A patient taking warfarin is prescribed a newly initiated medication known to inhibit
CYP2C9. Which outcome is most likely?
A. Reduced anticoagulant effect requiring higher warfarin doses.
B. Increased anticoagulant effect with elevated bleeding risk.
C. Complete loss of warfarin activity.
D. No clinically significant interaction.
🔴 Correct Answer: B. Increased anticoagulant effect with elevated bleeding risk.
🔵 Explanation: CYP2C9 inhibition decreases warfarin metabolism, increasing plasma
concentrations and enhancing anticoagulant activity. This raises the risk of bleeding
and typically necessitates closer INR monitoring. The interaction does not completely
eliminate or negate warfarin's effects.
,QUESTION 3.
An advanced practice nurse evaluates a patient whose blood pressure remains
uncontrolled despite adherence to therapy. Before intensifying treatment, which
action best reflects evidence-based prescribing?
A. Double all current medication doses.
B. Discontinue therapy and restart with another class.
C. Assess medication adherence, lifestyle factors, secondary causes, and
measurement accuracy.
D. Add two additional antihypertensive agents immediately.
🔴 Correct Answer: C. Assess medication adherence, lifestyle factors, secondary
causes, and measurement accuracy.
🔵 Explanation: Clinical guidelines recommend evaluating adherence, blood pressure
measurement technique, lifestyle contributors, and possible secondary hypertension
before escalating therapy. Immediate medication intensification without reassessment
may expose patients to unnecessary adverse effects.
QUESTION 4.
An older adult taking multiple medications presents with dizziness and recent falls.
Which prescribing principle should receive the highest priority?
A. Increase all medication doses gradually.
B. Continue therapy because chronic medications should never be discontinued.
C. Replace every medication with an over-the-counter alternative.
D. Conduct a comprehensive medication review to identify potentially inappropriate
medications.
🔴 Correct Answer: D. Conduct a comprehensive medication review to identify
potentially inappropriate medications.
🔵 Explanation: Polypharmacy substantially increases the risk of adverse drug events,
particularly among older adults. A systematic medication review helps identify
, medications contributing to falls and allows safer optimization of therapy.
Automatically increasing or substituting medications may worsen outcomes.
QUESTION 5.
A patient receiving an ACE inhibitor develops facial swelling and difficulty breathing
shortly after taking the medication. What is the most appropriate immediate
response?
A. Discontinue the medication immediately and treat as a medical emergency.
B. Reduce the dose and continue therapy.
C. Substitute another ACE inhibitor.
D. Continue therapy because symptoms usually resolve spontaneously.
🔴 Correct Answer: A. Discontinue the medication immediately and treat as a
medical emergency.
🔵 Explanation: Angioedema associated with ACE inhibitors is a potentially life-
threatening adverse reaction requiring immediate discontinuation and emergency
evaluation. Dose reduction or substitution within the same drug class is inappropriate
because recurrence may be severe.
QUESTION 6.
Which pharmacokinetic parameter most directly reflects the proportion of an
administered drug reaching systemic circulation unchanged?
A. Clearance.
B. Volume of distribution.
C. Bioavailability.
D. Half-life.
🔴 Correct Answer: C. Bioavailability.
🔵 Explanation: Bioavailability represents the fraction of an administered dose that
reaches the systemic circulation in active form. Clearance describes elimination, volume
