1. Which receptor is primarily targeted by beta-2 agonists?
A. Cardiac muscle
B. Smooth muscle of bronchi
C. Central nervous system
D. Renal tubules
Answer: B
Rationale: Beta-2 receptors are mainly located in bronchial
smooth muscle and mediate bronchodilation.
2. Which drug is a selective COX-2 inhibitor?
A. Ibuprofen
B. Aspirin
C. Celecoxib
D. Naproxen
Answer: C
,Rationale: Celecoxib selectively inhibits COX-2, reducing
inflammation with fewer GI side effects.
3. What is the antidote for heparin overdose?
A. Vitamin K
B. Protamine sulfate
C. Naloxone
D. Atropine
Answer: B
Rationale: Protamine sulfate binds and inactivates heparin.
4. Which phase of pharmacokinetics involves drug
metabolism?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Answer: C
Rationale: Metabolism primarily occurs in the liver via
cytochrome P450 enzymes.
5. Which opioid antagonist is used in overdose
emergencies?
A. Morphine
B. Fentanyl
C. Naloxone
D. Methadone
,Answer: C
Rationale: Naloxone rapidly reverses opioid effects by
competitive receptor antagonism.
6. Which organ is the primary site of drug excretion?
A. Liver
B. Kidney
C. Pancreas
D. Spleen
Answer: B
Rationale: The kidneys eliminate most drugs via urine.
7. What is the mechanism of ACE inhibitors?
A. Block angiotensin II receptors
B. Inhibit angiotensin-converting enzyme
C. Increase aldosterone secretion
D. Stimulate renin release
Answer: B
Rationale: ACE inhibitors block conversion of angiotensin I to
angiotensin II.
8. Which insulin is long-acting?
A. Lispro
B. Regular insulin
C. Glargine
D. NPH
Answer: C
, Rationale: Insulin glargine provides a steady basal insulin
level.
9. What is the mechanism of metformin?
A. Stimulates insulin secretion
B. Inhibits hepatic gluconeogenesis
C. Increases glucagon release
D. Blocks glucose absorption in intestines
Answer: B
Rationale: Metformin decreases hepatic glucose production.
10. Which antibiotic inhibits bacterial cell wall synthesis?
A. Tetracycline
B. Ciprofloxacin
C. Penicillin
D. Erythromycin
Answer: C
Rationale: Penicillins inhibit peptidoglycan cross-linking.
11. Which adverse effect is associated with
aminoglycosides?
A. Hepatotoxicity
B. Nephrotoxicity
C. Hypoglycemia
D. Constipation
Answer: B
