1. A patient taking an angiotensin-converting enzyme (ACE) inhibitor
develops a persistent dry cough. Which mechanism most directly
explains this adverse effect?
A. Increased aldosterone secretion
B. Accumulation of bradykinin
C. Increased sodium retention
D. Blockade of beta-2 receptors
Answer: B. Accumulation of bradykinin
Rationale: ACE normally contributes to the breakdown of bradykinin.
ACE inhibition therefore increases bradykinin concentrations, which can
produce a persistent dry cough. Angiotensin II and aldosterone
production are also reduced, but neither directly explains the
characteristic cough.
, 2. Which medication class is generally considered first-line
pharmacologic therapy for uncomplicated hypertension in many
adult patients?
A. Thrombolytics
B. Alpha-1 agonists
C. Thiazide-type diuretics
D. Class I antiarrhythmics
Answer: C. Thiazide-type diuretics
Rationale: Thiazide-type diuretics are established first-line
antihypertensive agents for many patients. They lower blood pressure
initially by promoting sodium and water excretion and, with continued
therapy, contribute to reduced peripheral vascular resistance.
3. A patient receiving warfarin has an international normalized ratio
(INR) substantially above the therapeutic range. What is the
primary concern?
A. Increased risk of thrombosis
B. Increased risk of bleeding
,C. Development of hypertension
D. Reduced anticoagulant activity
Answer: B. Increased risk of bleeding
Rationale: Warfarin reduces the synthesis of vitamin K-dependent
clotting factors. Excessive anticoagulation, reflected by an excessively
elevated INR, increases the patient's risk of clinically significant
bleeding.
4. Which laboratory test is most directly used to monitor the
therapeutic effect of unfractionated heparin?
A. INR
B. aPTT
C. Hemoglobin A1c
D. Serum creatinine only
Answer: B. aPTT
Rationale: The activated partial thromboplastin time (aPTT) is
commonly used to monitor unfractionated heparin therapy. INR is
primarily associated with warfarin monitoring. Anti-Xa testing may also
be used in selected circumstances.
, 5. Which adverse effect is particularly associated with
aminoglycoside antibiotics?
A. Nephrotoxicity and ototoxicity
B. Severe constipation and urinary retention
C. Hyperthyroidism
D. Gingival hyperplasia
Answer: A. Nephrotoxicity and ototoxicity
Rationale: Aminoglycosides such as gentamicin and amikacin can cause
kidney injury and damage to the auditory or vestibular systems. Because
toxicity can be dose- and exposure-related, appropriate monitoring is
important during therapy.
6. Which pharmacokinetic process describes the movement of a
drug from the gastrointestinal tract into systemic circulation?
A. Distribution
B. Metabolism
C. Absorption
D. Elimination
Answer: C. Absorption
