NCLEX Cardiac Practice Questions

Cardiac content shows up across the whole NCLEX: physiological adaptation, pharmacology and prioritization all lean on it. The questions tend to test whether you recognise deterioration early.

These practice questions focus on heart failure, acute coronary syndrome and the findings a nurse must act on first.

What the NCLEX tests in cardiac

5 cardiac practice questions with rationales

Answer each one before opening the rationale. Every option is explained, including the wrong ones.

Question 1 · Select all that apply
Which findings are consistent with left-sided heart failure? Select all that apply.
  1. Crackles in the lungs
  2. Dyspnea on exertion
  3. Jugular vein distention
  4. Orthopnea
  5. Dependent pedal edema
Show answer and rationale

Answer: A, B, D

A. Correct. Blood backs up into the lungs, causing pulmonary congestion.

B. Correct. Pulmonary congestion causes breathlessness with activity.

C. JVD reflects systemic venous congestion, a right-sided finding.

D. Correct. Lying flat worsens pulmonary congestion.

E. Dependent edema is a right-sided (systemic) finding.

Question 2 · Multiple choice
A client with chest pain has an ECG showing ST elevation. After calling for help and applying oxygen as needed, which prescribed medication should the nurse give first?
  1. Aspirin, chewed
  2. Furosemide IV
  3. Metoprolol PO at bedtime
  4. Atorvastatin PO
Show answer and rationale

Answer: A

A. Correct. Chewed aspirin early in an MI reduces platelet aggregation and mortality.

B. Furosemide treats fluid overload, not the coronary occlusion.

C. A beta blocker may be given, but not deferred to bedtime and not ahead of aspirin.

D. Statins are long-term therapy, not an emergency priority.

Question 3 · Multiple choice
A client with heart failure reports a weight gain of 2.5 lb (1.1 kg) since yesterday. What is the best interpretation?
  1. Normal day-to-day variation
  2. Likely fluid retention that should be reported
  3. Expected after starting a diuretic
  4. A sign of improved appetite
Show answer and rationale

Answer: B

A. A gain over about 2 lb in a day is not routine variation in heart failure.

B. Correct. A rapid gain of 2 to 3 lb in a day (or about 5 lb in a week) signals fluid retention and should be reported.

C. A diuretic should cause weight loss, not gain.

D. Appetite does not add over 2 lb overnight; this is fluid.

Question 4 · Multiple choice
Which lab result best supports a diagnosis of myocardial infarction?
  1. Elevated troponin
  2. Elevated BNP
  3. Low hemoglobin
  4. Elevated ALT
Show answer and rationale

Answer: A

A. Correct. Troponin is the most specific marker of heart muscle injury.

B. BNP reflects ventricular stretch, used for heart failure.

C. Low hemoglobin suggests anemia or bleeding.

D. ALT is a liver enzyme.

Question 5 · Select all that apply
The nurse is teaching a client being discharged with heart failure. Which statements show understanding? Select all that apply.
  1. "I will weigh myself every morning after I urinate."
  2. "I will limit my sodium intake."
  3. "I can stop my medicine once my ankles stop swelling."
  4. "I will call if I need more pillows to breathe at night."
  5. "I will take my furosemide in the morning."
Show answer and rationale

Answer: A, B, D, E

A. Correct. Same time, same scale, after voiding gives comparable daily weights.

B. Correct. Sodium causes fluid retention.

C. Heart failure medications are continued long term; stopping them causes relapse.

D. Correct. Worsening orthopnea is a sign of decompensation.

E. Correct. Morning dosing avoids nighttime urination.

How to study cardiac for the NCLEX

  1. Sort findings into "backs up into the lungs" (left) and "backs up into the body" (right).
  2. For chest pain, the priority is assessment and rapid treatment of ischemia, not documentation or teaching.
  3. Know which numbers matter: daily weight trends, potassium with digoxin and diuretics, troponin.

Frequently asked questions

Are cardiac questions on the NCLEX hard?

They are common rather than unusually hard. Most test early recognition of deterioration and the first action to take, which becomes predictable with practice.

What cardiac topics should I study most?

Heart failure, acute coronary syndrome, dysrhythmias, hypertension and cardiac medications like digoxin, beta blockers, anticoagulants and diuretics.

Can I practise cardiac questions from my lecture slides?

Yes. Upload your cardiac unit to NurseQuizAI and it builds NCLEX-style questions from it.
