1. A patient with heart failure is prescribed Furosemide. What
is the priority assessment?
A. Blood glucose
B. Potassium level
C. Hemoglobin
D. Temperature
Rationale: Loop diuretics cause potassium loss → risk of
arrhythmias.
2. A patient with Myocardial Infarction reports chest pain. What
is the first nursing action?
A. Administer morphine
B. Assess pain and vital signs
C. Call provider
,D. Prepare for surgery
Rationale: Always assess before intervening.
3. Which lab value is most specific for myocardial injury?
A. CK
B. Myoglobin
C. Troponin
D. BNP
Rationale: Troponin is the most specific cardiac marker.
4. A patient in atrial fibrillation is at risk for:
A. Hypotension
B. Stroke
C. Infection
D. Renal failure
Rationale: Blood pooling → clot formation → embolism.
5. Which medication is used for rate control in atrial
