Introduction:
This comprehensive practice examination is designed to prepare nursing students for the NURS 5663
Pharmacology weekly quizzes covering Weeks 1 through 6. It assesses foundational and applied knowledge of
pharmacokinetics, pharmacodynamics, autonomic and cardiovascular pharmacology, central nervous system
agents, pain management, antimicrobial therapy, and endocrine pharmacology. The exam employs multiple-
choice and scenario-based questions that challenge students to apply critical thinking, interpret medication orders,
and make sound pharmacological decisions. Emphasis is placed on real-world clinical application, drug safety,
,patient education, and the integration of core pharmacological principles necessary for successful quiz
performance and competent nursing practice.
Section One: Questions 1–100
1. A patient is prescribed a medication that undergoes extensive first-pass metabolism in the liver. Which
route of administration would MOST effectively bypass this effect?
A. Oral
B. Sublingual
C. Intravenous
D. Subcutaneous
🟢 C. Intravenous
🔴 RATIONALE: Intravenous administration bypasses first-pass metabolism because the drug enters the
systemic circulation directly, avoiding the liver's metabolic effects. Oral drugs are absorbed through the GI tract
and then pass through the liver via the portal circulation before reaching systemic circulation.
2. A drug with a half-life of 4 hours is administered intravenously. Approximately how long will it take for the
drug to reach 94% steady-state concentration?
,A. 8 hours
B. 12 hours
C. 16 hours
D. 24 hours
🟢 C. 16 hours
🔴 RATIONALE: Steady-state is reached after approximately four to five half-lives. With a half-life of 4 hours,
steady-state is reached in approximately 16-20 hours. At 4 half-lives (16 hours), the drug concentration reaches
94% of steady-state.
3. A nurse is preparing to administer a medication that is an agonist at beta-1 adrenergic receptors. Which
effect would the nurse expect to observe?
A. Bronchodilation
B. Increased heart rate and contractility
C. Peripheral vasodilation
D. Decreased blood pressure
🟢 B. Increased heart rate and contractility
🔴 RATIONALE: Beta-1 adrenergic receptors are primarily located in the heart. Activation of beta-1 receptors
results in increased heart rate (positive chronotropic effect) and increased myocardial contractility (positive
inotropic effect). Beta-2 receptors mediate bronchodilation and vasodilation.
, 4. A patient with hypertension is prescribed a beta-blocker that is cardioselective (beta-1 selective). Which
adverse effect is LEAST likely to occur with this medication compared to non-selective beta-blockers?
A. Bradycardia
B. Bronchospasm
C. Hypotension
D. Fatigue
🟢 B. Bronchospasm
🔴 RATIONALE: Cardioselective beta-1 blockers (e.g., metoprolol, atenolol) primarily block beta-1 receptors in
the heart, with less effect on beta-2 receptors in the lungs. Non-selective beta-blockers (e.g., propranolol) block
both beta-1 and beta-2 receptors, increasing the risk of bronchospasm in patients with asthma or COPD.
5. A patient prescribed warfarin (Coumadin) for atrial fibrillation is started on a new antibiotic. The nurse
should be most concerned about which potential drug interaction?
A. Increased risk of bleeding due to antibiotic interference with warfarin metabolism
B. Decreased effectiveness of warfarin
C. Increased risk of antibiotic resistance
D. No significant interaction
🟢 A. Increased risk of bleeding due to antibiotic interference with warfarin metabolism
