College 120+ Questions Detailed Answer!!
Section 1: Cardiovascular
1. A patient with heart failure is receiving furosemide. Which assessment finding requires
immediate action?
A. Weight loss of 1 kg in 24 hours
B. Serum potassium 3.1 mEq/L
C. Urine output 40 mL/hour
D. Trace pedal edema
Answer: B
Rationale: Hypokalemia (K+ <3.5) increases risk for digoxin toxicity and dysrhythmias.
Furosemide is a loop diuretic that causes potassium wasting. Weight loss of 1 kg/day is
expected; urine output >30 mL/hr is adequate; trace edema is expected in HF.
2. A patient with unstable angina is prescribed nitroglycerin sublingual. The patient reports a
headache after the first dose. What should the nurse do?
A. Hold the next dose and notify the provider
B. Administer acetaminophen as ordered
C. Stop the medication immediately
D. Reassure that this indicates the drug is working
, Answer: B
Rationale: Headache is a common side effect of nitroglycerin due to vasodilation. It often
diminishes with continued use. Acetaminophen can be given for pain. Stopping or holding
the drug is unnecessary unless headache is severe or accompanied by other symptoms.
3. A patient post-MI develops crackles in lung bases, S3 gallop, and jugular vein distension.
The nurse suspects:
A. Cardiogenic shock
B. Pericarditis
C. Left-sided heart failure
D. Right-sided heart failure
Answer: C
Rationale: Left-sided HF presents with pulmonary congestion (crackles), S3, and dyspnea.
JVD is more common in right-sided HF, but can occur in biventricular failure. Cardiogenic
shock would include hypotension and altered mental status.
4. Which lab value is most concerning in a patient taking warfarin for atrial fibrillation?
A. INR 2.5
B. PT 18 seconds
C. INR 4.8
D. aPTT 45 seconds
Answer: C
Rationale: Target INR for AF is 2–3. INR 4.8 increases bleeding risk significantly. PT 18
seconds is mildly elevated. aPTT monitors heparin, not warfarin.
5–20 (Additional cardiology questions on hypertension management, ECG interpretation,
post-cardiac arrest care, peripheral vascular disease, etc.) – Omitted for brevity but would be
included in full document.
