Correct Answer: C

Rationale: In this scenario, the client is showing signs of fluid volume excess, such as drowsiness, abdominal pain, headache, crackles in the lungs, bounding pulse, and elevated blood pressure. Decreasing the IV fluids to a keep vein open (KVO) rate is crucial to prevent further fluid overload. This intervention helps in balancing fluid intake and output to prevent complications associated with fluid volume excess. Calculating total intake and output (Choice A) may be necessary but not the immediate priority in managing fluid overload. Administering acetaminophen (Choice B) may help with managing the fever but does not address the underlying issue of fluid overload. Reviewing the last administration of IV pain medication (Choice D) is not the priority in this situation where fluid overload is a concern.

Correct Answer: B

Rationale: The correct answer is B: Moon face. Cushing's syndrome is characterized by excess cortisol levels, leading to the distinctive round and full face known as moon face. Hyperpigmentation (choice A) may occur due to increased ACTH levels, but it is not a hallmark symptom like moon face. Hypotension (choice C) is less common in Cushing's syndrome as cortisol typically leads to hypertension (choice D) due to its effects on blood pressure regulation.

Correct Answer: C

Rationale: The serum potassium level should be monitored closely in clients undergoing hemodialysis due to the risk of hyperkalemia. Hemodialysis is used to remove waste products and excess electrolytes like potassium from the blood. Monitoring potassium levels is crucial because an imbalance can lead to serious cardiac complications, making it the priority value to monitor in this scenario. Monitoring hemoglobin levels (choice A) is important for anemia assessment in chronic renal failure but is not directly related to hemodialysis. Blood urea nitrogen (BUN) levels (choice B) and creatinine levels (choice D) are commonly monitored in renal function tests but are not the top priority for monitoring in a client undergoing hemodialysis.

Correct Answer: D

Rationale: A bone marrow biopsy helps determine the best treatment plan for Hodgkin's disease by providing crucial information about the extent and nature of the disease. While confirming the diagnosis is important, the primary purpose of the biopsy in this case is to guide treatment decisions. The biopsy is not primarily for assessing the extent of the disease in the bones or checking for infections in the bones.
