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."
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. Cerebral blood flow. MAP is crucial for maintaining adequate cerebral perfusion pressure, ensuring enough blood flow to the brain.
B. The client's intake and output needs. MAP does not directly influence intake and output needs; it is more directly related to blood flow and tissue perfusion.
C. Regulation of blood pressure. MAP is a measure of average blood pressure but not a regulator of it.
D. Resorption of cerebrospinal fluid. CSF resorption is not directly influenced by MAP; it’s regulated by intracranial pressure and other factors.
