ANSWERS 2026/2027


1. Which pharmacokinetic process is most affected by decreased hepatic function?
xc xc xc xc xc xc xc xc xc




A. Absorption

B. Distribution

C. Metabolism

D. Excretion

Correct Answer: C xc xc




Explanation: The liver is the primary site of drug metabolism. Impaired hepatic function reduces m

etabolism, prolonging drug half-life and increasing toxicity risk.

D. Sublingual nitroglycerin xc




Correct Answer: A xc xc




Explanation: Drugs primarily cleared unchanged through the kidneys accumulate when renal funct

3. Which receptor type is primarily targeted by beta-blockers?
xc xc xc xc xc xc xc




A. Alpha-1 adrenergic xc




B. Beta-adrenergic

C. Muscarinic

,D. Dopaminergic

Correct Answer: B xc xc




Explanation: Beta-blockers block beta- xc xc xc




adrenergic receptors in the heart, reducing heart rate, myocardial contractility, and blood pressure.
