NSG 550 EXAM 3
1. A 68-year-old man with hypertension and diabetes
presents with substernal chest pressure radiating to the left
arm, associated with nausea and diaphoresis. ECG shows ST
depression in leads V3–V5. Troponin is elevated. Which
diagnosis best fits?
A) Unstable angina
,Page 2 of 225
B) NSTEMI
C) STEMI
D) Prinzmetal angina
Answer: B
Rationale: ST depression + elevated troponin = NSTEMI.
Unstable angina has normal troponin. STEMI requires ST
elevation. Prinzmetal is transient ST elevation with vasospasm.
2. A patient with NSTEMI is started on dual antiplatelet
therapy (DAPT). Which medications constitute DAPT? (SATA)
A) Aspirin
B) Clopidogrel
C) Warfarin
D) Ticagrelor
Answer: A, B, D (aspirin + P2Y12 inhibitor: clopidogrel,
ticagrelor, or prasugrel)
,Page 3 of 225
Rationale: DAPT reduces stent thrombosis and recurrent MI.
Warfarin is used for atrial fibrillation or mechanical valves,
not routine DAPT.
3. A 72-year-old woman with heart failure with preserved
ejection fraction (HFpEF) has dyspnea on exertion, elevated
jugular venous pressure, and peripheral edema. Which
medication is most likely to improve symptoms?
A) Spironolactone
B) Digoxin
C) Furosemide
D) Sacubitril/valsartan
Answer: C
Rationale: Loop diuretics are first-line for symptom relief in
HFpEF. Spironolactone may reduce hospitalizations but not as
rapidly symptomatic. Sacubitril/valsartan is for HFrEF.

4. On auscultation, you hear a mid-systolic click followed by a
late systolic murmur at the apex. What is the most likely
diagnosis?
A) Aortic stenosis
B) Mitral regurgitation due to mitral valve prolapse
C) Hypertrophic cardiomyopathy
D) Tricuspid regurgitation
Answer: B
Rationale: Mid-systolic click + late systolic murmur = mitral
valve prolapse with regurgitation. Maneuvers: squatting
delays click, standing moves it earlier.
5. A patient with atrial fibrillation (CHA₂DS₂-VASc = 4) is on
warfarin with INR 2.5. She falls and sustains a head
laceration but no intracranial bleed on CT. What should you
advise?
A) Stop warfarin for 7 days
