1. A nurse is caring for a client with acute myocardial infarction. Why does prolonged ischemia
lead to irreversible myocardial damage?
A. Reduced oxygen diffusion
B. Depletion of cellular ATP
C. Increased ventricular preload
,D. Enhanced inflammatory response
Correct Answer: B
Rationale:
Prolonged ischemia deprives myocardial cells of oxygen, halting aerobic metabolism. ATP
depletion leads to failure of cellular ion pumps, membrane disruption, and ultimately irreversible
cell death.
2. A nurse is assessing a client who has just received thrombolytic therapy. Which finding
requires immediate intervention?
A. Mild headache
B. Epistaxis
C. Sudden decrease in blood pressure
D. Warm extremities
Correct Answer: C
Rationale:
A sudden drop in blood pressure may indicate internal bleeding or hemorrhagic complications,
which are life-threatening and require prompt action.
3. A client with heart failure reports worsening dyspnea and orthopnea. Which intervention
should the nurse implement first?
A. Administer prescribed diuretic
B. Encourage fluid intake
C. Position the client in high Fowler’s
D. Assess lung sounds
Correct Answer: D
Rationale:
Assessment is the first step in the nursing process. Evaluating lung sounds helps identify
pulmonary edema or fluid overload, guiding timely interventions.
4. A nurse is caring for a client receiving IV nitroglycerin. Which assessment finding requires
immediate action?
A. Headache
B. Blood pressure 82/54 mmHg
C. Flushing
D. Mild dizziness
Correct Answer: B
Rationale:
Hypotension is a serious side effect of nitroglycerin and can compromise perfusion, requiring
immediate intervention.
5. A client is prescribed metoprolol after myocardial infarction. Which instruction is essential?
A. “Do not monitor your heart rate at home.”
B. “Take the medication even if you feel well.”
C. “Increase salt intake to prevent hypotension.”
D. “Stop taking the medication if fatigue occurs.”
Correct Answer: B
, Rationale:
Consistent medication adherence is crucial to prevent recurrent myocardial ischemia and control
blood pressure and heart rate.
6. A nurse is teaching a client about lifestyle changes after a myocardial infarction. Which
statement indicates understanding?
A. “I can return to heavy exercise immediately.”
B. “I should follow a low-sodium, heart-healthy diet.”
C. “Stress does not affect my heart recovery.”
D. “I can smoke as long as I exercise daily.”
Correct Answer: B
Rationale:
A heart-healthy diet reduces cardiovascular risk factors and promotes recovery after myocardial
infarction.
7. A nurse is caring for a client with an inferior wall MI. Which complication is most likely to
occur?
A. Atrial fibrillation
B. Right ventricular failure
C. Ventricular septal rupture
D. Pericardial effusion
Correct Answer: B
Rationale:
Inferior wall MI often involves the right ventricle, increasing the risk of right ventricular failure
and hypotension.
8. A nurse is monitoring a client receiving IV heparin. Which laboratory value is most important
to assess?
A. Hemoglobin
B. aPTT
C. Serum potassium
D. Platelet count
Correct Answer: B
Rationale:
Heparin prolongs aPTT, and monitoring ensures therapeutic anticoagulation while minimizing
bleeding risk.
9. A client with acute MI is prescribed oxygen therapy. What is the primary rationale?
A. Prevent infection
B. Reduce myocardial workload
C. Correct hypoxemia and improve oxygen delivery to tissues
D. Decrease heart rate
Correct Answer: C
Rationale:
Oxygen therapy increases oxygen availability to ischemic myocardial tissue, reducing hypoxia
and limiting myocardial injury.
