QUESTIONS | VERIFIED ANSWERS | COMPLETE TEST BANK
1. A patient with type 2 diabetes is started on metformin. Which of the
following is the primary mechanism of action of metformin?
A. Stimulates insulin secretion from pancreatic beta cells
B. Inhibits alpha-glucosidase enzymes in the gut
C. Increases insulin sensitivity in peripheral tissues
D. Decreases hepatic glucose production
E. Promotes glucose excretion through the kidneys
Correct Answer: D. Decreases hepatic glucose production
EXPERT RATIONALE: Metformin primarily works by inhibiting hepatic
gluconeogenesis, thereby reducing fasting blood glucose levels. It also improves
insulin sensitivity but its primary mechanism is reducing glucose output from the
liver.
,2. A nurse practitioner is prescribing a thiazide diuretic. Which electrolyte
imbalance is most commonly associated with this class of medication?
A. Hyperkalemia
B. Hypernatremia
C. Hypercalcemia
D. Hypokalemia
E. Hypermagnesemia
Correct Answer: D. Hypokalemia
EXPERT RATIONALE: Thiazide diuretics promote potassium excretion at the
distal tubule, leading to hypokalemia. Patients on long-term thiazide therapy
require monitoring of serum potassium levels.
3. Which of the following antibiotics works by inhibiting cell wall synthesis?
A. Azithromycin
B. Ciprofloxacin
C. Amoxicillin
D. Doxycycline
E. Gentamicin
Correct Answer: C. Amoxicillin
EXPERT RATIONALE: Amoxicillin is a penicillin-class antibiotic that inhibits
bacterial cell wall synthesis by binding to penicillin-binding proteins, preventing
cross-linking of peptidoglycan chains.
4. A patient is prescribed warfarin. Which vitamin directly antagonizes
warfarin's mechanism of action?
A. Vitamin A
,B. Vitamin B12
C. Vitamin C
D. Vitamin K
E. Vitamin D
Correct Answer: D. Vitamin K
EXPERT RATIONALE: Warfarin inhibits vitamin K-dependent clotting factors (II,
VII, IX, X). Vitamin K supplementation or foods rich in vitamin K can reverse the
anticoagulant effect of warfarin.
5. Which of the following beta-blockers is considered cardioselective?
A. Carvedilol
B. Propranolol
C. Labetalol
D. Metoprolol
E. Nadolol
Correct Answer: D. Metoprolol
EXPERT RATIONALE: Metoprolol is a beta-1 selective (cardioselective) blocker,
primarily affecting the heart with less effect on bronchial beta-2 receptors, making
it safer in patients with mild asthma or COPD.
6. A patient taking an ACE inhibitor develops a persistent dry cough. What is
the most appropriate next step?
A. Add an antihistamine to suppress the cough
B. Reduce the dose of the ACE inhibitor
C. Switch to a beta-blocker
, D. Switch to an angiotensin receptor blocker (ARB)
E. Discontinue all antihypertensives
Correct Answer: D. Switch to an angiotensin receptor blocker (ARB)
EXPERT RATIONALE: ACE inhibitors cause bradykinin accumulation, which leads
to a dry cough. ARBs block the angiotensin II receptor without affecting bradykinin
levels and are an appropriate alternative without this side effect.
7. Which of the following is the first-line treatment for Helicobacter pylori
eradication?
A. Omeprazole alone
B. Amoxicillin and metronidazole only
C. Bismuth and tetracycline only
D. Triple therapy: PPI + clarithromycin + amoxicillin
E. Ciprofloxacin and omeprazole
Correct Answer: D. Triple therapy: PPI + clarithromycin + amoxicillin
EXPERT RATIONALE: The standard first-line H. pylori eradication regimen is a
PPI combined with clarithromycin and amoxicillin for 10–14 days, achieving high
eradication rates.
8. A patient with gout is prescribed allopurinol. What is the mechanism of
action of allopurinol?
A. Promotes renal excretion of uric acid
B. Blocks prostaglandin synthesis
C. Inhibits uric acid reabsorption in the renal tubules
D. Inhibits xanthine oxidase, reducing uric acid production
E. Dissolves urate crystals in joints
