A nurse is reinforcing teaching to a client who has dilated cardiomyopathy (DCM). Which of the following statements by the nurse should be included in the teaching?

"Your heart condition is caused from stiffening of the walls of the ventricles."

"Your heart condition is caused by excessive stretching of the ventricles."

"Your heart condition is caused when the ventricular tissue becomes fibrous and fatty."

"Your heart condition is caused by thickening of the ventricular walls and septum."

Answer and Explanation

The Correct Answer is B

A. "Your heart condition is caused from stiffening of the walls of the ventricles." Stiffening of the ventricular walls describes restrictive cardiomyopathy, not DCM.

B. "Your heart condition is caused by excessive stretching of the ventricles." DCM involves excessive stretching and thinning of the ventricular walls, leading to impaired contraction.

C. "Your heart condition is caused when the ventricular tissue becomes fibrous and fatty." This describes arrhythmogenic right ventricular dysplasia, not DCM.

D. "Your heart condition is caused by thickening of the ventricular walls and septum." This describes hypertrophic cardiomyopathy, not DCM.

Correct Answer is A

Explanation

A. Obtain a pair of slipper socks for the client. Slipper socks can provide warmth without applying direct heat, which is safer for clients with impaired circulation.

B. Increase the client's oral fluid intake. Increasing fluids does not directly address cold feet and may be contraindicated depending on the client’s condition.

C. Rub the client's feet briskly for several minutes. Rubbing can damage skin and tissue in clients with poor circulation and should be avoided.

D. Place a moist heating pad under the client's feet. Heating pads can cause burns and further impair circulation in clients with vascular issues.

A. Obtain a blood sample. B. Initiate oxygen therapy. C. Attach the leads for a 12-lead ECG. D. Insert the IV catheter.

Correct Answer is B

Explanation

A. Obtain a blood sample. Although obtaining a blood sample is essential for cardiac enzyme levels, it is not the highest priority. Addressing oxygenation takes precedence to relieve hypoxia.

B. Initiate oxygen therapy. Oxygen is the first priority to improve oxygenation in a client showing signs of hypoxia (cyanosis, dyspnea), which can prevent further ischemic damage to the heart.

C. Attach the leads for a 12-lead ECG. While obtaining an ECG is essential for diagnosing myocardial ischemia, ensuring oxygenation is more critical in this moment.

D. Insert the IV catheter. An IV line is necessary to administer fluids and medications, but oxygenation should be prioritized first to stabilize the client.
