A patient's coronary blood flow is insufficient to meet the metabolic demands of the myocytes.
Which term will the nurse use to describe this process?

Choice A rationale:

The nurse should use the principle that the myocardium is rigid to guide nursing care for a patient with restrictive cardiomyopathy. Restrictive cardiomyopathy is characterized by the stiffening of the myocardium, which restricts the ability of the heart to fill with blood properly. This rigidity of the myocardium impairs diastolic function, leading to reduced cardiac output. Nursing care for patients with restrictive cardiomyopathy focuses on reducing symptoms and improving cardiac function. This involves strategies to reduce the workload on the heart, such as salt and fluid restriction, medications to manage heart failure symptoms, and possibly diuretics to reduce volume overload. Additionally, managing comorbid conditions and providing emotional support are essential components of care.

Choice B rationale:

Dilated myocardium is not a characteristic of restrictive cardiomyopathy. Dilated cardiomyopathy is a separate type of heart muscle disorder characterized by an enlarged and weakened left ventricle.

Choice C rationale:

Hypertrophied myocardium is not a characteristic of restrictive cardiomyopathy. Hypertrophic cardiomyopathy is a different type of heart muscle disorder characterized by thickening of the heart muscle, particularly in the left ventricle.

Choice D rationale:

Thickened myocardium is not typically associated with restrictive cardiomyopathy. Thickening of the myocardium is more commonly seen in hypertrophic cardiomyopathy.

Choice A rationale:

A male with an enlarged upper chest Enlarged upper chest in a male may suggest the development of pectoral muscles or chest-related muscular hypertrophy but is not a specific risk factor for coronary artery disease (CAD). The question is about CAD risk, and a male with an enlarged upper chest does not necessarily indicate a higher risk of CAD.

Choice B rationale:

A female with abdominal obesity Abdominal obesity, especially in females, is a significant risk factor for coronary artery disease (CAD). Excess fat around the abdomen can contribute to the development of atherosclerosis and increase the risk of CAD. This choice is correct because it highlights a well-established risk factor for CAD.

Choice C rationale:

A male with an active lifestyle Having an active lifestyle is generally associated with a reduced risk of CAD. Regular physical activity can help improve cardiovascular health, lower blood pressure, and reduce the risk of CAD. Therefore, a male with an active lifestyle is less likely to have a high risk of CAD.

Choice D rationale:

A female with menstrual problems Menstrual problems, while they can indicate hormonal imbalances or other health issues, are not directly linked to an increased risk of coronary artery disease. CAD risk factors typically revolve around lifestyle, genetics, and metabolic factors, which are not addressed by menstrual problems.
