When assessing a client with dilated cardiomyopathy, the nurse understands that the most common clinical manifestation is___________ due to______________
1. Dyspnea; bronchial compression
2. Cyanosis; decreased oxygenation
3. Peripheral edema; decreased renal perfusion
4. Confusion; decreased cerebral perfusion
Dyspnea/bronchial compression
Rationale: Dyspnea occurs because the enlarged heart compresses the bronchioles, thus diminishing the amount of oxygen entering and leaving the lungs. Additionally, blood backs up into the lungs due to heart failure that is common to dilated cardiomyopathy. Cyanosis, peripheral edema, and confusion may be present, but they are not the most common clinical manifestation.
