An elderly client diagnosed with cardiomyopathy reports having to rest between activities during the day. The nurse realizes the reason for this client's fatigue would be:
1. Decreased cardiac output.
2. Increased blood pressure.
3. An elongated and dilated aorta.
4. Increased stroke volume.
1. Decreased cardiac output.
Rationale:
Decreased cardiac output is a result of decreased efficiency and contractibility of the myocardium. Rest could be required after each activity that puts physiological stress on the heart. Less blood is pumped from the heart to the rest of the body with a decreased cardiac output, and this has a direct effect on the activity level that can be tolerated. It is unknown if the client has high blood pressure, an elongated and dilated aorta, or increased stroke volume.
