,QUESTION 1.
A 72-year-old patient with chronic kidney disease (eGFR 28 mL/min/1.73 m²) is
prescribed a medication that is primarily eliminated unchanged through the
kidneys. Which prescribing action best minimizes the risk of drug accumulation
while maintaining therapeutic efficacy?
A. Adjust the dose or dosing interval based on renal function.
B. Double the loading dose while maintaining the maintenance dose.
C. Continue the standard dosage because hepatic metabolism compensates.
D. Reduce protein intake before modifying therapy.
🔴 Correct Answer: A. Adjust the dose or dosing interval based on renal
function.
🔵 Explanation: Drugs primarily eliminated by the kidneys may accumulate in
patients with significantly reduced renal function, increasing the risk of toxicity.
Adjusting either the dose or dosing interval is the standard pharmacokinetic
approach. A larger loading dose is generally unnecessary, hepatic metabolism
does not automatically compensate for reduced renal clearance, and dietary
protein changes do not correct impaired drug elimination.
QUESTION 2.
A patient taking warfarin begins trimethoprim-sulfamethoxazole therapy for a
urinary tract infection. Which outcome is most likely?
A. Reduced anticoagulant activity requiring dosage escalation.
B. Increased anticoagulant effect with elevated bleeding risk.
C. Complete elimination of INR variability.
D. Enhanced vitamin K synthesis by intestinal bacteria.
🔴 Correct Answer: B. Increased anticoagulant effect with elevated bleeding
risk.
🔵 Explanation: Trimethoprim-sulfamethoxazole inhibits warfarin metabolism and
alters intestinal flora, increasing INR and bleeding risk. Close INR monitoring and
,dose adjustment are often required. The remaining options contradict the
well-established interaction between these medications.
QUESTION 3.
A patient with hypertension, type 2 diabetes mellitus, and microalbuminuria
requires antihypertensive therapy. Which medication class offers the greatest
additional renal protective benefit?
A. Calcium channel blockers
B. Loop diuretics
C. ACE inhibitors
D. Alpha-1 blockers
🔴 Correct Answer: C. ACE inhibitors
🔵 Explanation: ACE inhibitors reduce intraglomerular pressure and slow
progression of diabetic kidney disease by decreasing proteinuria. While other
antihypertensive agents lower blood pressure, they generally do not provide the
same degree of nephroprotection demonstrated by ACE inhibitors in diabetic
patients with albuminuria.
QUESTION 4.
A patient develops persistent cough shortly after beginning lisinopril therapy.
Which mechanism best explains this adverse effect?
A. Increased prostaglandin synthesis
B. Enhanced norepinephrine release
C. Bradykinin accumulation
D. Histamine receptor stimulation
🔴 Correct Answer: C. Bradykinin accumulation
🔵 Explanation: ACE inhibition decreases the degradation of bradykinin, allowing
accumulation that contributes to the characteristic dry cough. Histamine release is
not the primary mechanism, and prostaglandin or norepinephrine changes do not
adequately explain this adverse effect.
, QUESTION 5.
A patient receiving insulin therapy experiences diaphoresis, tremors, tachycardia,
and confusion before lunch. What is the priority intervention?
A. Administer intravenous sodium bicarbonate.
B. Confirm hypoglycemia and administer rapid-acting carbohydrate if the patient
can safely swallow.
C. Delay treatment until laboratory confirmation is available.
D. Administer long-acting insulin immediately.
🔴 Correct Answer: B. Confirm hypoglycemia and administer rapid-acting
carbohydrate if the patient can safely swallow.
🔵 Explanation: Symptomatic hypoglycemia requires immediate recognition and
treatment to prevent neurologic injury. Rapid-acting carbohydrates are
appropriate for conscious patients who can swallow safely. Delaying treatment or
administering additional insulin would worsen hypoglycemia.
QUESTION 6.
A patient receiving long-term systemic corticosteroid therapy abruptly discontinues
the medication. Which complication is most concerning?
A. Hyperthyroidism
B. Acute adrenal insufficiency
C. Hyperparathyroidism
D. Increased endogenous cortisol production
🔴 Correct Answer: B. Acute adrenal insufficiency
🔵 Explanation: Chronic corticosteroid therapy suppresses the
hypothalamic-pituitary-adrenal axis. Abrupt discontinuation may precipitate
adrenal crisis because endogenous cortisol production remains suppressed.
Gradual tapering allows recovery of adrenal function.
