1. Which pharmacokinetic process is most affected by decreased hepatic function?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Correct Answer: C
Explanation: The liver is the primary site of drug metabolism. Impaired hepatic function
reduces metabolism, prolonging drug half-life and increasing toxicity risk.
2. A patient with renal failure requires dosage adjustments for which type of medication?
A. Drugs excreted unchanged by the kidneys
B. Drugs metabolized by the liver
C. Topical corticosteroids
D. Sublingual nitroglycerin
Correct Answer: A
Explanation: Drugs primarily cleared unchanged through the kidneys accumulate
when renal function declines, requiring dosage reduction.
3. Which receptor type is primarily targeted by beta-blockers?
A. Alpha-1 adrenergic
B. Beta-adrenergic
C. Muscarinic
,D. Dopaminergic
Correct Answer: B
Explanation: Beta-blockers block beta-adrenergic receptors in the heart, reducing
heart rate, myocardial contractility, and blood pressure.
4. Select all that apply: Common side effects of ACE inhibitors include:
A. Dry cough
B. Hyperkalemia
C. Hypoglycemia
D. Bradycardia
Correct Answers: A, B
Explanation: ACE inhibitors cause dry cough from bradykinin accumulation and can
increase potassium retention.
5. Which of the following best describes a partial agonist?
A. Produces no effect when binding to a receptor
B. Produces the same maximal effect as a full agonist
C. Produces a smaller maximal response, even when all receptors are occupied
D. Blocks receptor activation
Correct Answer: C
Explanation: Partial agonists bind to receptors but produce less than maximal
activation, even at high doses.
, 6. Which adverse effect is most associated with aminoglycoside antibiotics?
A. Hepatotoxicity
B. Ototoxicity and nephrotoxicity
C. Hypoglycemia
D. Hypotension
Correct Answer: B
Explanation: Aminoglycosides (e.g., gentamicin) can cause renal tubular damage and
hearing loss due to toxicity.
7. Which of the following best defines first-pass metabolism?
A. Drug metabolism occurring in the kidney before systemic circulation
B. Degradation of oral drugs in the liver before reaching systemic circulation
C. Distribution of the drug in fatty tissues
D. The rate of absorption in the intestine
Correct Answer: B
Explanation: First-pass metabolism occurs in the liver, reducing bioavailability of oral
medications.
8. Which medication is contraindicated in pregnancy due to teratogenicity?
A. Acetaminophen
B. ACE inhibitors
C. Penicillin
D. Heparin
