Correct Answer: D

Rationale: Although physical activity restrictions are commonly recommended for younger clients with hypertrophic cardiomyopathy (HCM) to reduce the risk of sudden cardiac death, this may not be the best option for a 72-year-old client. Older adults can still benefit from regular physical activity to maintain overall health and mobility. It is important to individualize the exercise recommendations based on the client's overall health status, functional capacity, and specific considerations related to their condition. In this case, the healthcare team would likely focus on other treatment options such as beta-blocker or calcium channel blocker administration, and consider the potential benefits of defibrillator implantation for the older client with HCM.

Correct Answer: D

Rationale: Torsades de Pointes is a specific type of ventricular tachycardia characterized by a distinctive twisting pattern on an ECG. It is often associated with a prolonged QT interval and can potentially lead to a life-threatening arrhythmia known as ventricular fibrillation. Sinus tachycardia, atrial flutter, and junctional escape rhythms are not forms of ventricular tachycardia.

Correct Answer: B

Rationale: In a client with left-sided heart failure, lying on the left side can help reduce the workload on the heart by promoting better venous return and reducing preload. This position can help decrease the amount of blood in the pulmonary circulation and improve cardiac output. Placing one pillow under the head can provide comfort and proper alignment of the airway, allowing for easier breathing. It is important to avoid excessive elevation of the head as it could increase pressure on the heart and impede circulatory function. This position can also help prevent complications such as pulmonary congestion and fluid accumulation in the lungs.

Correct Answer: D

Rationale: Creatinine clearance is a diagnostic test that helps determine both the glomerular filtration rate (GFR) and the extent of glomerular damage in the renal system. Creatinine is a waste product produced by muscles and excreted by the kidneys. A decrease in the glomerular filtration rate indicates impaired kidney function, which could be due to glomerular damage or other renal issues. By measuring the amount of creatinine in the blood and urine over a specific period of time, creatinine clearance provides an estimate of the GFR. This test is commonly used to assess kidney function in patients with renal disease or renal impairment.

Correct Answer: B

Rationale: - Compression stockings help promote blood circulation in the legs, decreasing the risk of blood clots forming. This is important after surgery, especially in older adults who may have a higher risk.
