Question 1
A patient taking warfarin begins therapy with trimethoprim-
sulfamethoxazole. What is the most likely outcome?
A. Decreased INR
B. No change in anticoagulation
C. Increased INR and bleeding risk
D. Reduced drug absorption
Answer: C. Increased INR and bleeding risk
Rationale: Trimethoprim-sulfamethoxazole inhibits warfarin
metabolism, increasing anticoagulant effects and significantly
raising the risk of bleeding.
Question 2
,Which receptor is primarily responsible for bronchodilation
when stimulated by beta-agonists?
A. Alpha-1
B. Beta-1
C. Beta-2
D. Muscarinic
Answer: C. Beta-2
Rationale: Beta-2 receptor stimulation relaxes bronchial smooth
muscle, producing bronchodilation and improving airflow in
obstructive airway diseases.
Question 3
Which laboratory value should be monitored most closely in a
patient receiving unfractionated heparin?
A. INR
B. aPTT
C. Platelet count only
D. Hemoglobin A1c
Answer: B. aPTT
Rationale: Activated partial thromboplastin time (aPTT) is used
to monitor the therapeutic effectiveness and safety of
unfractionated heparin therapy.
Question 4
A patient develops a persistent dry cough while taking lisinopril.
The most appropriate action is to:
,A. Increase the dose
B. Continue therapy without evaluation
C. Switch to an ARB if appropriate
D. Add a beta blocker
Answer: C. Switch to an ARB if appropriate
Rationale: ACE inhibitors can cause a dry cough due to
bradykinin accumulation. Angiotensin receptor blockers provide
similar benefits with a lower incidence of cough.
Question 5
Which medication class is considered first-line treatment for
hyperlipidemia due to its LDL-lowering effect?
A. Fibrates
B. Statins
C. Niacin
D. Bile acid sequestrants
Answer: B. Statins
Rationale: Statins inhibit HMG-CoA reductase, significantly
reducing LDL cholesterol and lowering cardiovascular risk.
Question 6
Which adverse effect is most commonly associated with long-
term corticosteroid therapy?
A. Hypoglycemia
B. Osteoporosis
, C. Bradycardia
D. Hearing loss
Answer: B. Osteoporosis
Rationale: Chronic corticosteroid use decreases bone formation
and increases bone resorption, placing patients at risk for
osteoporosis and fractures.
Question 7
A patient taking digoxin presents with nausea, visual
disturbances, and confusion. What should the clinician suspect?
A. Therapeutic response
B. Digoxin toxicity
C. Allergic reaction
D. Serotonin syndrome
Answer: B. Digoxin toxicity
Rationale: Gastrointestinal symptoms, confusion, and visual
disturbances are classic signs of digoxin toxicity and require
immediate evaluation.
Question 8
Which pharmacokinetic process describes the movement of a
drug from systemic circulation into tissues?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
