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 ["B","C"]
Explanation
A. Increased number of individuals utilizing technology in their homes: While technology use may impact various aspects of cognitive function and mental health, there is insufficient evidence to suggest a direct correlation between technology use and the growing numbers of clients diagnosed with dementia.
B. Increased number of the population living longer: One of the primary risk factors for dementia is advancing age. As the population ages and life expectancy increases, there is a higher prevalence of dementia due to the age-related degenerative changes in the brain.
C. Increased number of Americans over the age of 65: Aging is the most significant risk factor for dementia. The aging population, particularly those over 65 years old, is experiencing a higher prevalence of dementia due to age-related changes in the brain.
D. Increased number of the population traveling abroad: There is no direct association between traveling abroad and the growing numbers of clients diagnosed with dementia in the United States. While certain environmental factors or exposures may influence dementia risk, travel patterns are not considered a significant contributing factor to the overall prevalence of dementia.
E. Increased number of Americans attending college: There is no evidence to suggest a direct link between attending college and the prevalence of dementia. Educational attainment may have a protective effect against dementia, but it is not a factor driving the growing numbers of diagnoses in the United States.
Correct Answer is D
Explanation
A. "I stopped taking aspirin last week.": Stopping aspirin medication prior to surgery is often advised to reduce the risk of bleeding during and after the procedure. The nurse may confirm the timing of discontinuation with the client and verify if any other anticoagulant medications are being taken.
B. "I did not put my contact lenses in this morning.": Removing contact lenses before surgery is a routine precaution to prevent potential corneal abrasions or complications during the procedure. This statement indicates the client is following preoperative instructions.
C. "I took my blood pressure meds with a sip of water.": Taking blood pressure medications with a small amount of water is generally acceptable before surgery. However, the nurse may verify the specific medications the client is taking and their dosing schedule to ensure compliance.
D. "I had a cough and runny nose a couple days ago.": This statement requires further investigation as respiratory symptoms, such as cough and runny nose, may indicate an underlying respiratory infection. Infections can increase the risk of complications during surgery, such as anesthesia-related respiratory issues or postoperative infections. The nurse should assess the severity and duration of the symptoms, inquire about any fever or recent exposure to illnesses, and consider notifying the surgical team for further evaluation and decision-making regarding the client's surgical readiness.
