Correct Answer: B

Rationale: While it is important for individuals with cardiomyopathy to maintain a well-balanced diet that includes adequate protein, stating that increasing dietary protein specifically helps with cardiac cell repair may not be entirely accurate. The primary focus for individuals with cardiomyopathy should be on overall heart-healthy choices such as monitoring sodium intake, avoiding high-fat, high-cholesterol foods, and following a well-rounded diet plan. Protein can be a part of this plan but it should not be emphasized as the main component for cardiac cell repair. Consulting with a dietitian who can provide personalized guidance and recommendations based on the individual's specific condition is crucial.

Correct Answer: D

Rationale: The correct instruction for a client who is scheduled for temporary pacemaker insertion is to use battery-powered equipment. This is because temporary pacemakers are powered by an external power source, typically a battery pack worn by the client. Therefore, it is important for the client to be aware of this and ensure that they have access to the necessary battery-powered equipment at home for the pacemaker to function properly. The other options are not appropriate instructions for a client with a temporary pacemaker.

Correct Answer: C

Rationale: Pulmonary embolism (PE) is a serious condition where a blood clot travels to the lungs and blocks blood flow, which can be life-threatening. Common clinical manifestations of PE include sudden onset of dyspnea (difficulty breathing), chest pain (sharp, stabbing pain that may worsen with deep breaths), tachypnea (rapid breathing), tachycardia (rapid heart rate), and possibly cough or hemoptysis (coughing up blood). In the context of a client recovering from a hysterectomy, it is crucial to recognize the signs of PE as early intervention is essential to prevent serious complications. Nausea, decreased urine output, and activity intolerance are not typical clinical manifestations of a pulmonary embolism and should not be the primary focus when suspecting a PE in this scenario.

Correct Answer: C

Rationale: Based on the blood pressure categories defined by the American Heart Association, hypertension is classified as having a systolic blood pressure (top number) of 130 mm Hg or higher and/or a diastolic blood pressure (bottom number) of 80 mm Hg or higher. The client's blood pressure reading of 150/90 mm Hg falls within the range of hypertension, indicating elevated blood pressure levels that may require monitoring and/or intervention to reduce the risk of cardiovascular complications.

Correct Answer: A

Rationale: A. Muscle spasms: Nitroprusside infusion can lead to cyanide toxicity, which can cause muscle spasms as a symptom. It is essential for the nurse to monitor the client for any signs of muscle spasms during the infusion.
