Correct Answer: B

Rationale: The correct answer is B: 'I should avoid foods with high sodium content.' Clients with Cushing syndrome need to limit their sodium intake to help reduce fluid retention and manage hypertension, which are common complications of the syndrome. Increasing calcium intake (choice A) is not specifically indicated for Cushing syndrome. Decreasing vitamin D intake (choice C) is not a typical dietary modification for this condition. Consuming more potassium-rich foods (choice D) is not a primary focus of dietary modifications for Cushing syndrome.

Correct Answer: C

Rationale: A fever of 100.4°F is the most concerning assessment finding in a client with ESRD scheduled for hemodialysis. This elevation in temperature may indicate an underlying infection, which can lead to serious complications in individuals with compromised renal function. Prompt intervention is necessary to prevent the spread of infection and deterioration of the client's condition. The other vital signs mentioned, such as blood pressure, heart rate, and respiratory rate, while important to monitor, are within acceptable ranges and do not pose an immediate threat like a fever indicative of infection.

Correct Answer: A

Rationale: Placing a portable toilet next to the bed is the most appropriate intervention in this situation. It reduces the need for the client to walk long distances, thereby preventing falls and reducing discomfort. Choice B, assisting with walking exercises, would not be suitable for a client with muscular dystrophy who is experiencing awkwardness and clumsiness. Choice C, providing pain medication, may address the symptom but does not directly address the issue of reducing the need for walking. Choice D, applying a heating pad, may provide temporary relief but does not address the underlying issue of mobility and fall prevention.

Correct Answer: A

Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.

Correct Answer: B

Rationale: The statement 'I should take my antacids regularly, even if I don't have symptoms' indicates a misunderstanding. Antacids should only be taken when symptoms are present to neutralize excess stomach acid. Taking antacids regularly when not experiencing symptoms may lead to metabolic alkalosis. Choices A, C, and D are correct statements for a client with peptic ulcer disease as they all focus on avoiding irritants that can exacerbate the condition.
