QUESTION 1.
A 62-year-old patient with hypertension and type 2 diabetes has an estimated
glomerular filtration rate (eGFR) of 42 mL/min/1.73 m². The patient requires initiation
of a medication primarily eliminated by the kidneys. Which prescribing approach best
minimizes the risk of drug accumulation while maintaining therapeutic efficacy?
,A. Prescribe the standard adult dose because age is a greater predictor of clearance
than renal function.
B. Adjust the initial dose or dosing interval according to renal function and continue
monitoring response.
C. Avoid prescribing all renally eliminated medications regardless of indication.
D. Double the loading dose to achieve therapeutic concentrations before reducing
maintenance dosing.
🔴 Correct Answer: B. Adjust the initial dose or dosing interval according to renal
function and continue monitoring response.
🔵 Explanation: Renal impairment reduces drug clearance for medications eliminated
through the kidneys, making dosage adjustment essential to reduce toxicity while
preserving efficacy. Therapeutic monitoring and reassessment are important as renal
function may change over time. The other options either overgeneralize, ignore renal
function, or increase toxicity risk.
QUESTION 2.
A patient with newly diagnosed hypertension also has diabetic kidney disease with
albuminuria. Which initial antihypertensive therapy provides both blood pressure
reduction and renal protection?
A. Thiazide diuretic
B. Calcium channel blocker
C. ACE inhibitor
D. Alpha-1 blocker
🔴 Correct Answer: C. ACE inhibitor
🔵 Explanation: ACE inhibitors are recommended because they lower blood pressure
while reducing intraglomerular pressure and slowing progression of diabetic kidney
disease. Thiazides and calcium channel blockers effectively lower blood pressure but do
not provide the same degree of renal protection in albuminuric disease. Alpha blockers
are not considered first-line therapy.
QUESTION 3.
A patient taking warfarin develops a urinary tract infection requiring antibiotic
,therapy. Which prescribing consideration is most appropriate?
A. Antibiotic therapy never affects anticoagulation.
B. Warfarin should always be discontinued during antibiotic treatment.
C. Increase the warfarin dose to prevent thrombosis.
D. Assess for clinically significant drug interactions and increase INR monitoring.
🔴 Correct Answer: D. Assess for clinically significant drug interactions and
increase INR monitoring.
🔵 Explanation: Many antibiotics alter warfarin metabolism or vitamin K production by
gut flora, increasing bleeding risk. Enhanced INR monitoring allows timely dose
adjustment. Automatically stopping or increasing warfarin is inappropriate without
clinical assessment.
QUESTION 4.
A patient with persistent asthma reports increasing use of a short-acting beta-
agonist inhaler several times daily. Which intervention best reflects evidence-based
pharmacologic management?
A. Increase reliance on the rescue inhaler alone.
B. Add an inhaled corticosteroid-containing controller regimen.
C. Discontinue bronchodilator therapy completely.
D. Replace the inhaler with an oral antibiotic.
🔴 Correct Answer: B. Add an inhaled corticosteroid-containing controller
regimen.
🔵 Explanation: Frequent rescue inhaler use suggests inadequate asthma control and
persistent airway inflammation. Inhaled corticosteroids are the foundation of long-term
controller therapy. The remaining options fail to address the underlying inflammatory
process.
QUESTION 5.
A patient receiving chronic opioid therapy presents for follow-up. Which assessment
most directly supports safe long-term prescribing?
, A. Evaluate pain severity only.
B. Refill medication without reassessment because chronic therapy has already been
established.
C. Assess pain control, functional improvement, adverse effects, and evidence of
misuse.
D. Increase the opioid dose at every follow-up visit.
🔴 Correct Answer: C. Assess pain control, functional improvement, adverse
effects, and evidence of misuse.
🔵 Explanation: Chronic opioid management requires balancing analgesia, functional
outcomes, safety, and misuse risk. Decisions should be individualized based on
comprehensive reassessment rather than pain intensity alone. Automatic refills or dose
escalation increase the likelihood of adverse outcomes.
QUESTION 6.
A patient with hypothyroidism begins levothyroxine therapy. Which instruction is
most appropriate to optimize medication absorption?
A. Take with calcium supplements every morning.
B. Take with breakfast containing dairy products.
C. Take immediately before bedtime with iron tablets.
D. Take on an empty stomach with water, separated from calcium and iron products.
🔴 Correct Answer: D. Take on an empty stomach with water, separated from
calcium and iron products.
🔵 Explanation: Levothyroxine absorption is reduced by calcium, iron, and certain
foods. Taking it on an empty stomach with water promotes consistent bioavailability.
The alternative options increase the likelihood of reduced therapeutic effectiveness.
QUESTION 7.
A patient with type 2 diabetes has established cardiovascular disease. Which factor
should strongly influence selection of glucose-lowering therapy?
A. Medication color preference.
B. Availability of once-yearly dosing.
