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."

Answer and Explanation

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 C

Explanation

A. "I notice the ringing when I'm not concentrating on something." This statement suggests that the client notices the tinnitus but does not imply a significant impact on their well-being. It indicates that the tinnitus occurs when the client is not focused on tasks, which may not necessarily affect their overall functioning or well-being.

B. "I am still able to complete my work in a timely manner." This statement indicates that the client can still function adequately in their work despite experiencing tinnitus. While this may suggest some level of coping, it does not directly address the impact of tinnitus on the client's overall well-being.

C. "The ringing in my ears is distracting." This is the correct answer. This statement indicates that the tinnitus is distracting to the client, which suggests that it may affect their concentration, focus, or overall quality of life. The distraction caused by tinnitus can significantly impact daily activities and well-being.

D. "Hopefully a treatment for this ringing in my ears will help." While this statement acknowledges the presence of tinnitus and the desire for treatment, it does not directly address the impact of tinnitus on the client's well-being. It focuses more on the hope for relief through treatment rather than the current impact on their quality of life.

A. Limit exercise to 10 min, 2 days per week. B. Monitor blood pressure C. Lose weight if necessary D. Eat a diet high in saturated fats. E. Maintain current cholesterol level

Correct Answer is ["B","C"]

Explanation

A. Limit exercise to 10 min, 2 days per week. This recommendation is incorrect. Regular physical activity is essential for heart health. The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise per week, spread throughout the week.

B. Monitor blood pressure This recommendation is correct. Monitoring blood pressure is an essential aspect of heart disease prevention. High blood pressure (hypertension) is a significant risk factor for heart disease, so regular monitoring allows for early detection and management.

C. Lose weight if necessary. This recommendation is correct. Maintaining a healthy weight or losing weight if overweight or obese is important for heart disease prevention. Excess weight, especially around the abdomen, increases the risk of heart disease and other health conditions.

D. Eat a diet high in saturated fats. This recommendation is incorrect. A diet high in saturated fats is associated with an increased risk of heart disease. Instead, the nurse should encourage a heart-healthy diet that includes fruits, vegetables, whole grains, lean proteins, and healthy fats.

E. Maintain current cholesterol level This recommendation is not entirely accurate. While maintaining healthy cholesterol levels is important for heart health, individuals with high cholesterol levels may need to take steps to lower their cholesterol through lifestyle modifications and, in some cases, medication. Therefore, simply maintaining current cholesterol levels may not be sufficient for heart disease prevention.
