A nurse is teaching a client who has dilated cardiomyopathy (DCM) about this condition. Which of the following statements by the nurse should be included in the teaching?
"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 from stiffening of the walls of the ventricles."
"Your heart condition is caused by thickening of the ventricular walls and septum."
The Correct Answer is A
A. "Your heart condition is caused by excessive stretching of the ventricles": Dilated cardiomyopathy (DCM) is characterized by the dilation or enlargement of the heart's chambers, particularly the ventricles. This dilation results in weakened myocardial contraction and impaired systolic function. The primary cause of DCM is often idiopathic (unknown), but it can also be secondary to various factors such as genetics, infections, toxins, or systemic diseases. The statement correctly identifies the pathophysiological basis of DCM as excessive stretching or dilation of the ventricles, leading to impaired cardiac function.
B. "Your heart condition is caused when the ventricular tissue becomes fibrous and fatty": This statement is incorrect. Fibrous and fatty changes in ventricular tissue are characteristic of another type of cardiomyopathy known as hypertrophic cardiomyopathy (HCM), not dilated cardiomyopathy (DCM). In DCM, the primary abnormality is dilation of the heart chambers rather than fibrous and fatty changes in the myocardium.
C. "Your heart condition is caused from stiffening of the walls of the ventricles": This statement describes restrictive cardiomyopathy (RCM), not dilated cardiomyopathy (DCM). In restrictive cardiomyopathy, the ventricular walls become stiff and rigid, impairing diastolic filling and ventricular relaxation. However, in DCM, the primary abnormality is dilation or enlargement of the ventricles rather than stiffening of the ventricular walls.
D. "Your heart condition is caused by thickening of the ventricular walls and septum": This statement describes hypertrophic cardiomyopathy (HCM), not dilated cardiomyopathy (DCM). In HCM, there is abnormal thickening of the ventricular walls and septum, leading to reduced chamber size and impaired diastolic filling. However, in DCM, the primary abnormality is dilation or enlargement of the ventricles rather than thickening of the ventricular walls.

Correct Answer is D
Explanation
A. "I should ask my son to drive me to the grocery store." This statement does not directly address the risk for sudden cardiac death associated with arrhythmogenic cardiomyopathy. While it may be a valid safety precaution to have someone else drive, it does not specifically address the client's understanding of the condition and its implications for sudden cardiac death.
B. "I will probably become easily constipated." Constipation is not a typical manifestation or complication of arrhythmogenic cardiomyopathy. This statement does not demonstrate an understanding of the condition and its associated risk of sudden cardiac death.
C. "I am aware that I may develop frequent hiccups." Frequent hiccups are not a characteristic symptom or complication of arrhythmogenic cardiomyopathy. This statement does not indicate an understanding of the condition and its risk for sudden cardiac death.
D. "I will need to avoid strenuous activity to prevent my heart from stopping." This statement reflects an understanding of the condition and its associated risk of sudden cardiac death. Strenuous activity can exacerbate arrhythmias in individuals with arrhythmogenic cardiomyopathy, potentially leading to life-threatening arrhythmias such as ventricular fibrillation. Avoiding strenuous activity is a recommended precaution to reduce the risk of sudden cardiac death in individuals with this condition.
Correct Answer is B
Explanation
A. Female sex: While gender can influence the risk of certain health conditions, such as cardiovascular diseases, there isn't a direct correlation between being female and an increased risk of delirium. Both males and females can develop delirium under certain circumstances.
B. History of drug and alcohol use: A history of drug and alcohol use increases the risk for the development of delirium. Substance abuse, including alcohol, illicit drugs, and certain prescription medications, can disrupt neurotransmitter function and lead to alterations in mental status, including delirium. Additionally, withdrawal from alcohol or drugs can precipitate delirium in susceptible individuals.
C. Lack of medical insurance: While access to healthcare and socioeconomic factors can impact overall health outcomes, there isn't a direct association between lack of medical insurance and an increased risk of delirium. Delirium is more closely linked to medical conditions, substance use, and other physiological factors.
D. History of lymphoma: While certain medical conditions, such as infections, metabolic disturbances, and neurological disorders, can increase the risk of delirium, there isn't a direct correlation between a history of lymphoma and the development of delirium. Delirium is more commonly associated with acute illness, surgery, or medication use.
