1. A 62-year-old patient with heart failure with reduced
ejection fraction (HFrEF, EF 30%) presents with NYHA class III
symptoms. Current medications include lisinopril 20 mg daily,
carvedilol 25 mg twice daily, and furosemide 40 mg daily.
Which addition is most beneficial for reducing mortality based
on current guidelines?
A. Hydralazine 75 mg four times daily
B. Digoxin 0.125 mg daily
C. Spironolactone 25 mg daily
D. Metolazone 5 mg daily
1
,Answer: C
Rationale: Spironolactone, an aldosterone antagonist, reduces
mortality and hospitalizations in patients with NYHA class II-IV
HFrEF when added to ACE inhibitors and beta-blockers .
Hydralazine/nitrates are beneficial primarily in African
American patients. Digoxin reduces hospitalizations but not
mortality.
2. A 55-year-old male with hypertension is currently on
lisinopril 20 mg daily, but his BP remains 152/94 mmHg. His
serum creatinine is 1.8 mg/dL (baseline 0.9 mg/dL). What is
the most appropriate next step?
A. Add hydrochlorothiazide 25 mg daily
B. Increase lisinopril to 40 mg daily
C. Add amlodipine 5 mg daily
D. Discontinue lisinopril and start losartan
Answer: C
2
,Rationale: The rise in creatinine (up to 30% from baseline is
acceptable) suggests the patient is dependent on angiotensin II
for renal perfusion. Adding a dihydropyridine calcium channel
blocker (amlodipine) is effective and safe. Increasing the ACE
inhibitor further may worsen renal function.
3. Which of the following medication pairs should be
AVOIDED together due to a significant interaction?
A. Lisinopril and amlodipine
B. Clopidogrel and omeprazole
C. Atorvastatin and ezetimibe
D. Metoprolol and hydralazine
Answer: B
Rationale: Omeprazole (a proton pump inhibitor) is a potent
inhibitor of CYP2C19, the enzyme required to convert
clopidogrel to its active metabolite. This interaction reduces
3
, antiplatelet efficacy and increases the risk of thrombotic events.
Pantoprazole or famotidine are preferred alternatives.
Domain 1A.2: Critical Care
4. An 80-kg patient with septic shock requires norepinephrine
infusion for BP support. The order reads "Norepinephrine 16
mg in 250 mL D5W titrate to MAP >65 mmHg." At what rate
(mL/hr) will the infusion provide the standard starting dose?
A. 5 mL/hr
B. 10 mL/hr
C. 15 mL/hr
D. 20 mL/hr
Answer: B
Rationale: Concentration = 16 mg/250 mL = 0.064 mg/mL.
Standard starting dose = 0.05 mcg/kg/min. (0.05 mcg/kg/min
