A nurse is providing education about the pathophysiology of cardiomyopathy to the family of a child who has been recently diagnosed with the condition. Which of the following statements made by a caregiver indicates understanding?

A. While right-sided workload can be affected in some forms of cardiomyopathy, the statement is inaccurate because the muscle does not typically become thinner in response to increased workload. Ventricular hypertrophy usually results in thickening, not thinning. B. Partially correct but incomplete. Cardiomyopathy often affects both ventricles, not just the left side, and can result in thickened or stiffened ventricular walls depending on the type (e.g., hypertrophic, restrictive, dilated). C. Cardiomyopathy typically involves increased workload on the ventricles, causing ventricular hypertrophy (thickened muscle) or dilation, which impairs the heart’s ability to pump effectively. This statement reflects a clear understanding of the pathophysiology. D. Cardiomyopathy primarily affects the ventricles, not the atria, and increased workload generally leads to thickened or stiffened myocardium rather than thinning.
