,Question 1
A 68-year-old man with hypertension, type 2 diabetes, chronic kidney disease (eGFR 48
mL/min/1.73 m²), and persistent albuminuria is taking amlodipine 10 mg daily. His blood
pressure remains 148/88 mmHg despite adherence. Which medication is the most appropriate
addition?

A. Hydrochlorothiazide

B. Lisinopril

C. Metoprolol tartrate

D. Clonidine

Correct Answer: B. Lisinopril

Rationale: ACE inhibitors are first-line therapy for patients with diabetes, hypertension, and
albuminuric chronic kidney disease because they reduce intraglomerular pressure, slow CKD
progression, and improve cardiovascular outcomes. Hydrochlorothiazide lowers blood pressure
but offers less renal protection. Metoprolol is not preferred as initial add-on therapy without
another indication such as coronary artery disease or heart failure. Clonidine is generally
reserved for resistant hypertension because of sedation, rebound hypertension, and limited long-
term outcome data.




Question 2
A 56-year-old woman develops diffuse muscle pain three weeks after starting high-intensity
atorvastatin therapy. Her CK level is mildly elevated. What is the most appropriate next step?

A. Continue the same dose and reassure the patient

B. Discontinue atorvastatin temporarily and evaluate for statin-associated muscle
symptoms

C. Switch immediately to gemfibrozil

D. Begin prednisone therapy

Correct Answer: B. Discontinue atorvastatin temporarily and evaluate for statin-associated
muscle symptoms

,Rationale: Temporary discontinuation helps determine whether symptoms are statin-related
before considering rechallenge or an alternative statin. Continuing therapy may worsen
symptoms. Gemfibrozil increases the risk of statin-associated myopathy and is not the preferred
substitute. Corticosteroids are not indicated for uncomplicated statin-associated muscle
symptoms.




Question 3
A patient with newly diagnosed atrial fibrillation has a CHA₂DS₂-VASc score of 4 and no
contraindications to anticoagulation. Which therapy best reduces the risk of ischemic stroke?

A. Aspirin alone

B. Clopidogrel alone

C. Apixaban

D. Dual antiplatelet therapy

Correct Answer: C. Apixaban

Rationale: Direct oral anticoagulants such as apixaban are preferred for most patients with
nonvalvular atrial fibrillation because they effectively reduce stroke risk with a favorable
bleeding profile compared with warfarin in many patients. Aspirin and clopidogrel alone provide
substantially less protection. Dual antiplatelet therapy is not an adequate substitute for
anticoagulation in this setting.




Question 4
A 25-year-old patient with moderate persistent asthma reports daily symptoms despite regular
low-dose inhaled corticosteroid therapy. Which management strategy is most appropriate?

A. Continue current therapy

B. Replace the inhaled corticosteroid with montelukast

C. Add a long-acting beta₂-agonist in combination with the inhaled corticosteroid

D. Start oral prednisone indefinitely

, Correct Answer: C. Add a long-acting beta₂-agonist in combination with the inhaled
corticosteroid

Rationale: For moderate persistent asthma that remains uncontrolled on low-dose inhaled
corticosteroids, guideline-directed step-up therapy includes adding a LABA while continuing
inhaled corticosteroids. Montelukast alone is generally less effective. Chronic oral prednisone
carries substantial long-term toxicity and is reserved for severe disease.




Question 5
A hospitalized patient develops profuse watery diarrhea after completing broad-spectrum
antibiotics. Which pharmacologic intervention is most appropriate after diagnostic confirmation?

A. Loperamide alone

B. Ciprofloxacin

C. Oral vancomycin

D. Amoxicillin-clavulanate

Correct Answer: C. Oral vancomycin

Rationale: Oral vancomycin is a recommended first-line treatment for many initial episodes of
Clostridioides difficile infection. Loperamide may worsen disease by delaying toxin clearance.
Ciprofloxacin and amoxicillin-clavulanate are not recommended therapies and may contribute to
further disruption of the gut microbiome.




Question 6
A patient with heart failure with reduced ejection fraction (LVEF 30%) remains symptomatic
despite optimal ACE inhibitor and beta-blocker therapy. Which medication has demonstrated
additional mortality benefit?

A. Digoxin

B. Verapamil

C. Spironolactone

D. Diltiazem
