Which of the following principles should the nurse use to guide nursing care for a patient with restrictive cardiomyopathy? The myocardium is:.

Rigid.

Dilated.

Hypertrophied.

Thickened.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is C

Explanation

Choice A rationale:

Choice A is not the answer. Hypertension refers to high blood pressure and is not the term used to describe insufficient coronary blood flow to meet the metabolic demands of myocytes. Therefore, this statement is not relevant to the scenario described.

Choice B rationale:

Choice B is not the answer. Metabolic syndrome is a cluster of conditions that increase the risk of heart disease, stroke, and type 2 diabetes. It is not the term used to describe insufficient coronary blood flow. Therefore, this statement is not relevant in this context.

Choice C rationale:

The correct answer is choice C. Myocardial ischemia is the term used to describe insufficient coronary blood flow to meet the metabolic demands of myocytes. Myocardial ischemia occurs when the heart muscle (myocardium) does not receive enough blood and oxygen to function properly, which can lead to chest pain or angina. This term accurately describes the scenario provided in the question.

Choice D rationale:

Choice D is not the answer. Diuresis refers to increased urine production and is not the term used to describe insufficient coronary blood flow. Therefore, this statement is not relevant in this context.

A. Right-sided heart failure. B. Left-sided heart failure. C. Low-output failure. D. High-output failure.

Correct Answer is A

Explanation

Choice A rationale:

Elevated pulmonary vascular resistance can lead to right-sided heart failure. In conditions such as chronic obstructive pulmonary disease (COPD) and pulmonary hypertension, increased resistance in the pulmonary circulation can cause the right ventricle of the heart to work harder to pump blood into the lungs. Over time, this can lead to right-sided heart failure. The rationale for this choice is that when the right ventricle fails, it can result in symptoms such as peripheral edema, jugular venous distension, hepatomegaly, and ascites, which are characteristic of right-sided heart failure.

Choice B rationale:

Left-sided heart failure is not typically associated with chronic pulmonary disease and elevated pulmonary vascular resistance. Left-sided heart failure is more commonly linked to conditions like hypertension, coronary artery disease, and valvular heart diseases. It leads to symptoms such as pulmonary congestion, dyspnea, and orthopnea, rather than the signs of right-sided heart failure.

Choice C rationale:

Low-output failure is a generic term that can refer to both left and right-sided heart failure. It does not specifically address the relationship between chronic pulmonary disease and elevated pulmonary vascular resistance. Low-output failure occurs when the heart cannot pump a sufficient amount of blood to meet the body's demands, and it can be due to either left or right-sided heart failure.

Choice D rationale:

High-output failure is a less common type of heart failure and is typically not associated with chronic pulmonary disease and elevated pulmonary vascular resistance. It occurs when the heart is pumping a higher-than-normal volume of blood but still cannot meet the body's metabolic demands. Causes of high-output failure may include conditions like anemia, hyperthyroidism, or arteriovenous shunts.
