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.
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:
Encouraging foods high in calcium is not appropriate for a patient with hyperhomocysteinemia, as explained in the rationale for . choice A.
Choice B rationale:
Potassium is not directly related to the management of hyperhomocysteinemia, as mentioned in the rationale for . choice B.
Choice C rationale:
Folate is the correct choice for managing hyperhomocysteinemia, as explained in the rationale for . choice C. Folate is essential in lowering homocysteine levels by aiding in its metabolism.
Choice D rationale:
Encouraging foods high in protein is not the primary approach to managing hyperhomocysteinemia, as discussed in the rationale for . choice D.
Correct Answer is D
Explanation
Choice A rationale:
Choice A is not the answer. Syncope refers to fainting or losing consciousness, and it is not typically an assessment finding associated with pulmonary edema. The symptoms of pulmonary edema are more related to respiratory distress and fluid overload rather than loss of consciousness. Therefore, this statement is not relevant to the development of pulmonary edema in left-sided heart failure.
Choice B rationale:
Choice B is not the answer. Weak pulses and decreased skin temperature are not specific assessment findings for pulmonary edema. In pulmonary edema, patients often exhibit symptoms such as shortness of breath, wheezing, crackles in the lungs, and pink frothy sputum. These symptoms are related to the accumulation of fluid in the lungs, rather than changes in peripheral pulses or skin temperature.
Choice C rationale:
Choice C is not the answer. Oliguria refers to reduced urine output, and while it can be related to kidney dysfunction in some cases, it is not a direct assessment finding of pulmonary edema. Pulmonary edema primarily presents with respiratory symptoms, such as severe dyspnea, cough, and audible crackles in the lungs, due to fluid accumulation.
Choice D rationale:
The correct answer is choice D. Dyspnea and cough are key assessment findings that indicate to the nurse that pulmonary edema has developed in a patient with left-sided (congestive) heart failure. Pulmonary edema is characterized by the accumulation of fluid in the lungs, leading to severe difficulty in breathing (dyspnea) and a productive cough with frothy, pink-tinged sputum. These respiratory symptoms are typical of pulmonary edema and should alert the nurse to its presence. .
