Question 1
A nurse is reviewing the phases of pharmacokinetics. Which of the following is the correct order?
A. Absorption, Distribution, Metabolism, Excretion
B. Distribution, Absorption, Metabolism, Excretion
C. Metabolism, Absorption, Distribution, Excretion
D. Excretion, Metabolism, Distribution, Absorption
Correct Answer: A
Rationale: The four phases in order are: Absorption, Distribution, Metabolism, Excretion (ADME).
Question 2
A nurse is reviewing the concept of bioavailability. Which route has 100% bioavailability?
A. Oral
B. Intravenous
C. Subcutaneous
D. Intramuscular
Correct Answer: B
Rationale: IV administration has 100% bioavailability because the drug is delivered directly into the
bloodstream.
Question 3
A nurse is reviewing the concept of first-pass metabolism. Which route bypasses first-pass
metabolism?
A. Oral
B. Sublingual
C. Rectal
D. B and C
Correct Answer: D
Rationale: Sublingual and rectal bypass first-pass metabolism.

Question 4
A nurse is reviewing the concept of drug half-life. A drug has a half-life of 4 hours. How long to reach
steady state (4-5 half-lives)?
A. 8 hours
B. 12 hours
C. 16-20 hours
D. 24 hours
Correct Answer: C
Rationale: Steady state in 4-5 half-lives: 16-20 hours.
Question 5
A nurse is reviewing the concept of therapeutic index. Which drug has a narrow therapeutic index?
A. Penicillin
B. Warfarin
C. Metformin
D. Lisinopril
Correct Answer: B
Rationale: Warfarin has a narrow therapeutic index requiring close monitoring.
Question 6
A nurse is reviewing cytochrome P450 enzymes. Which drug is an enzyme inducer?
A. Cimetidine
B. Rifampin
C. Fluconazole
D. Ketoconazole
Correct Answer: B
Rationale: Rifampin is an enzyme inducer. Cimetidine, fluconazole, and ketoconazole are inhibitors.
Question 7
A nurse is reviewing cytochrome P450 enzymes. Which drug is an enzyme inhibitor?
A. Rifampin
B. Phenobarbital
C. Cimetidine
D. Carbamazepine
Correct Answer: C
, 3
Rationale: Cimetidine is an enzyme inhibitor. Rifampin, phenobarbital, and carbamazepine are
inducers.
Question 8
A nurse is reviewing the mechanism of action of beta-2 agonists. Which of the following is the
primary effect?
A. Vasoconstriction
B. Bronchodilation
C. Increased heart rate
D. Decreased renin release
Correct Answer: B
Rationale: Beta-2 receptor stimulation causes bronchodilation.
Question 9
A nurse is reviewing the mechanism of action of alpha-1 blockers. Which of the following is the
primary effect?
A. Bronchodilation
B. Vasodilation
C. Increased heart rate
D. Increased renin release
Correct Answer: B
Rationale: Alpha-1 blockade causes vasodilation.
Question 10
A nurse is reviewing the mechanism of action of muscarinic antagonists. Which of the following is a
common side effect?
A. Diarrhea
B. Dry mouth
C. Bradycardia
D. Bronchoconstriction
Correct Answer: B
Rationale: Muscarinic antagonists cause dry mouth, constipation, and urinary retention.
Question 11
A nurse is reviewing the mechanism of action of proton pump inhibitors. Which of the following is
the primary mechanism?
