A client admitted with acute dyspnea is diagnosed with dilated cardiomyopathy. Which information will the nurse include when teaching the client about management of this disorder?
No more than two alcoholic drinks daily are recommended.
Notify the doctor about any symptoms of heart failure such as shortness of breath.
Elevating the legs above the heart will help relieve angina.
Careful compliance with diet and medications will prevent heart failure.
The Correct Answer is B
A. Alcohol can worsen cardiomyopathy; in most cases, complete avoidance is recommended rather than limiting to two drinks.
B. Early recognition of worsening heart failure symptoms, such as dyspnea, edema, or fatigue, is critical so prompt medical intervention can prevent complications.
C. Elevating the legs may relieve peripheral edema but does not address angina or heart failure management in dilated cardiomyopathy.
D. Compliance with diet and medications helps manage symptoms but cannot completely prevent heart failure progression; ongoing monitoring is essential.

Correct Answer is B
Explanation
A. Sinus tachycardia may occur due to pain, anxiety, or hypoxia but is nonspecific for myocardial infarction.
B. ST-segment elevation is a key indicator of acute myocardial injury and is used to diagnose ST-elevation myocardial infarction (STEMI), requiring urgent intervention.
C. The absence of Q waves is normal; the presence of pathologic Q waves develops later in MI and indicates myocardial necrosis.
D. Frequent premature atrial contractions are usually benign and not specific for acute MI.
Correct Answer is B
Explanation
A. Morphine does not raise systemic vascular resistance; it primarily causes vasodilation.
B. Morphine reduces systemic and pulmonary vascular resistance (vasodilation), decreases preload and afterload, reduces cardiac workload, decreases myocardial oxygen demand, and alleviates pain, making it beneficial in acute MI.
C. Morphine does not increase myocardial contractility; increasing contractility would raise oxygen demand, which is undesirable in MI.
D. Morphine decreases venous return rather than increasing it, which helps reduce cardiac workload.
