What assessment finding is the nurse's highest priority to report
immediately for a client experiencing an acute myocardial infarction?
Answer: New onset of chest pain unrelieved by nitroglycerin
accompanied by hypotension.
Rationale: Persistent chest pain despite nitroglycerin and the
development of hypotension may indicate worsening myocardial
ischemia, cardiogenic shock, or extensive myocardial damage.
Immediate intervention is necessary to preserve cardiac function and
prevent further complications.
A client with heart failure reports sleeping on four pillows at night.
What does this finding most likely indicate?
Answer: Orthopnea caused by worsening left-sided heart failure.
Rationale: Orthopnea develops when fluid redistributes into the lungs
while lying flat, increasing pulmonary congestion. Requiring multiple
,pillows is a classic sign of worsening left ventricular failure and should
prompt further evaluation.
Which laboratory value is most helpful in evaluating the severity of
heart failure?
Answer: B-type natriuretic peptide (BNP).
Rationale: BNP is released when ventricular walls are stretched due to
increased pressure and volume. Elevated BNP levels strongly suggest
heart failure and help differentiate cardiac causes of dyspnea from
pulmonary conditions.
A nurse is caring for a client receiving intravenous heparin. Which
laboratory result requires the most immediate intervention?
Answer: Activated partial thromboplastin time (aPTT) significantly
above the therapeutic range.
Rationale: Excessively prolonged aPTT greatly increases the risk for life-
threatening bleeding. The infusion should be evaluated promptly
according to facility protocol and the healthcare provider notified.
Which assessment finding is expected in a client with left-sided heart
failure?
, Answer: Crackles heard over both lung bases.
Rationale: Left ventricular failure causes blood to back up into the
pulmonary circulation, resulting in pulmonary edema and crackles. This
finding reflects fluid accumulation within the alveoli.
A client develops sudden severe chest pain that radiates to the left arm
and jaw. What is the nurse's priority action?
Answer: Obtain a 12-lead electrocardiogram and activate the chest pain
protocol.
Rationale: Early identification of myocardial ischemia allows for rapid
reperfusion therapy. Obtaining an ECG within minutes of symptom
onset is a critical component of evidence-based myocardial infarction
management.
Which assessment finding is most characteristic of right-sided heart
failure?
Answer: Jugular venous distention with peripheral edema.
