A nurse is teaching a client who has restrictive cardiomyopathy (RCM). Which of the following statements should the nurse include in the client teaching to explain the cause of RCM?

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

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

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

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

Answer and Explanation

The Correct Answer is B

A. "Your heart condition is caused by excessive stretching of the ventricles": This statement is incorrect. Excessive stretching of the ventricles typically occurs in dilated cardiomyopathy, not restrictive cardiomyopathy (RCM). In RCM, the primary issue is not excessive stretching but rather stiffening of the ventricular walls.

B. "Your heart condition is caused from stiffening of the walls of the ventricles": This statement is correct. Restrictive cardiomyopathy (RCM) is characterized by abnormal stiffening (fibrosis) of the ventricular walls, which impairs the heart's ability to fill properly during the diastolic phase of the cardiac cycle. This stiffening restricts the heart's ability to relax and fill with blood efficiently.

C. "Your heart condition is caused by thickening of the ventricular walls and septum": This statement describes hypertrophic cardiomyopathy (HCM), not restrictive cardiomyopathy (RCM). In HCM, there is abnormal thickening of the ventricular walls and septum, leading to impaired filling of the ventricles and potential obstruction of blood flow out of the heart.

D. "Your heart condition is caused when the ventricular tissue becomes fibrous and fatty": This statement describes arrhythmogenic right ventricular cardiomyopathy (ARVC), not restrictive cardiomyopathy (RCM). ARVC is characterized by replacement of myocardial tissue with fibrous and fatty tissue, primarily affecting the right ventricle.

Correct Answer is B

Explanation

B. Provide opportunities for education and continually evaluate the client's preferences and goals for care:
This is the most effective intervention. Providing education and involving the client (to the extent possible) in decision-making helps reduce anxiety and build trust. Even though individuals with Alzheimer's disease may have limited memory and cognitive abilities, ongoing communication about the transition and individualized care plans can help ease the process. Additionally, continuously evaluating the client's preferences and goals ensures that the care plan remains person-centered and aligns with their needs, helping to minimize relocation stress.

A. Elevated erythrocyte sedimentation rate (ESR) B. Elevated thyroid-stimulating hormone (TSH) C. Elevated brain natriuretic peptide (BNP) D. Elevated C-reactive protein (CRP)

Correct Answer is B

Explanation

A. Elevated erythrocyte sedimentation rate (ESR): Elevated ESR indicates inflammation in the body and is not typically associated with the cause of atrial fibrillation.

B. Elevated thyroid-stimulating hormone (TSH): This is the correct answer. A common cause of atrial fibrillation is hyperthyroidism, which is characterized by an overactive thyroid gland and often presents with elevated TSH levels. Thyroid hormones play a significant role in regulating heart rate and rhythm. Excess thyroid hormone can lead to increased heart rate and irregular heart rhythms, including atrial fibrillation.

C. Elevated brain natriuretic peptide (BNP): Elevated BNP levels are associated with heart failure and may indicate cardiac stress or dysfunction. While heart failure can predispose individuals to atrial fibrillation, elevated BNP levels themselves are not a direct cause of atrial fibrillation.

D. Elevated C-reactive protein (CRP): Elevated CRP levels indicate inflammation in the body and are associated with various cardiovascular diseases. While inflammation can contribute to atrial fibrillation, elevated CRP levels alone are not a direct cause of atrial fibrillation.
