Correct Answer: D

Rationale: A glomerular filtration rate of 14 mL/min indicates severe kidney impairment and the need for hemodialysis. The other choices, such as BUN 16 mg/dL, serum magnesium 1.8 mg/dL, and serum phosphorus 4.0 mg/dL, are within normal ranges and do not directly indicate the need for hemodialysis in chronic kidney disease.

Correct Answer: C

Rationale: The correct answer is a low-sodium diet. Patients with chronic kidney disease are often advised to follow a low-sodium diet to help manage fluid retention. Excessive sodium intake can lead to fluid buildup in the body, causing complications for individuals with kidney issues. Choices A and B are incorrect because while protein intake may need to be monitored in kidney disease, the primary focus is typically on sodium restriction. Choice D is incorrect as a high-sodium diet would exacerbate fluid retention in patients with chronic kidney disease.

Correct Answer: C

Rationale: Administering fluids is the appropriate action for a healthcare provider to take when a patient has a high fever and is disoriented. Dehydration can worsen confusion and other symptoms in such a situation. Administering acetaminophen or cooling the patient with cold compresses may help reduce the fever but does not address the underlying issue. Administering antibiotics is not indicated for a high fever and disorientation without knowing the cause.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is commonly seen in patients taking furosemide and requires close monitoring. Choices B, C, and D are incorrect because furosemide does not typically cause hyponatremia, hyperkalemia, or hypercalcemia as frequently as it causes hypokalemia.

Correct Answer: C

Rationale: Elevating the head of the bed to 45 degrees during feedings is the correct intervention to prevent aspiration in clients with a nasogastric tube. This position helps reduce the risk of regurgitation and subsequent aspiration of stomach contents into the lungs. Flushing the tube with water before feedings (Choice A) is not necessary for preventing aspiration. Checking for gastric residuals (Choice B) helps monitor feeding tolerance but does not directly prevent aspiration. Placing the client in the left lateral position (Choice D) is not specifically indicated for preventing aspiration in a client with a nasogastric tube.
