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. The ST segment is above the isoelectric line. B. The QRS intervals are 0.08 second. C. The QT interval is equal to the R to R interval. D. The PR intervals are 0.15 second.

Correct Answer is A

Explanation

A. The ST segment is above the isoelectric line. An elevated ST segment is a hallmark sign of acute myocardial infarction (MI), indicating myocardial injury.

B. The QRS intervals are 0.08 second. A QRS interval of 0.08 seconds is within the normal range and does not indicate myocardial infarction.

C. The QT interval is equal to the R to R interval. QT interval measurements are not diagnostic for acute MI.

D. The PR intervals are 0.15 second. A PR interval of 0.15 seconds is within the normal range and is not indicative of acute MI.
