Q1.
A novel oral anticoagulant is a direct factor Xa inhibitor with a bioavailability of 50% that is
primarily eliminated renally. In a patient with moderate hepatic impairment (Child-Pugh B),
which pharmacokinetic parameter is most likely to be significantly altered, requiring dose
adjustment?
A. Absorption B. Distribution
C. Metabolism D. Excretion
Correct: C - Metabolism
Rationale:Hepatic impairment affects drug metabolism, particularly for drugs metabolized by
CYP enzymes. Direct factor Xa inhibitors like rivaroxaban are metabolized in the liver, so
Child-Pugh B cirrhosis can increase systemic exposure. Absorption is less affected,
distribution changes are minimal, and renal excretion is not directly impacted by hepatic
function.
Q2.
A patient on a stable dose of warfarin is started on a short course of a broad-spectrum
antibiotic for pneumonia. The INR rises from 2.3 to 4.8 within 48 hours. Which mechanism
best explains this interaction?
A. Displacement of warfarin from protein B. Inhibition of CYP2C9-mediated warfarin
binding metabolism
C. Reduction of gut flora vitamin K synthesis D. Increased warfarin absorption due to
antibiotic-induced gut changes
Correct: C - Reduction of gut flora vitamin K synthesis
Rationale:Broad-spectrum antibiotics reduce gut flora that produce vitamin K, leading to
decreased vitamin K availability and enhanced warfarin effect. While some antibiotics inhibit
CYP2C9, the rapid onset and typical pattern support the vitamin K mechanism. Protein
binding displacement is minor and transient, and absorption changes are not significant.

Q3.
A patient with chronic heart failure is prescribed digoxin. Which concurrent medication is
most likely to increase the risk of digoxin toxicity by reducing its renal clearance?
A. Furosemide B. Amiodarone
C. Metformin D. Lisinopril
Correct: B - Amiodarone
Rationale:Amiodarone inhibits P-glycoprotein-mediated renal tubular secretion of digoxin,
increasing digoxin levels and toxicity risk. Furosemide may cause hypokalemia, which
potentiates digoxin toxicity but does not reduce clearance. Metformin and lisinopril do not
significantly affect digoxin clearance.
Q4.
Which pharmacodynamic principle best explains the observation that a drug's effect
reaches a plateau despite increasing the dose beyond a certain point?
A. Receptor desensitization B. Saturation of drug transporters
C. Maximal efficacy of the drug-receptor D. Competitive antagonism
system
Correct: C - Maximal efficacy of the drug-receptor system
Rationale:Maximal efficacy is the ceiling effect of a drug, determined by the number of
receptors and the efficiency of signal transduction. Once all receptors are occupied, additional
drug produces no further effect. Receptor desensitization reduces response over time, not
with dose. Transporters and competitive antagonism affect potency, not maximal efficacy.
Q5.
A patient with a history of peptic ulcer disease requires long-term NSAID therapy for
osteoarthritis. Which co-therapy is most evidence-based for reducing the risk of
NSAID-induced gastric ulcers?
A. Misoprostol B. Histamine-2 receptor antagonist
C. Antacid D. Sucralfate
Correct: A - Misoprostol
Rationale:Misoprostol is the only agent shown to significantly reduce serious NSAID-induced
ulcer complications, including perforation and bleeding. H2 receptor antagonists reduce
duodenal but not gastric ulcers. Antacids and sucralfate are not effective for prevention.
