Correct Answer: D

Rationale: The correct answer is D because taking pain medication at regular intervals helps maintain consistent pain control after surgery. Option A is incorrect because waiting for the pain to become unbearable can lead to inadequate pain management. Option B is incorrect as it suggests increasing medication without a schedule. Option C is incorrect because waiting for the pain to be severe before taking medication is not proactive pain management.

Correct Answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.

Correct Answer: D

Rationale: The correct answer is D because a client with pneumonia and a new onset of confusion needs immediate evaluation for changes in neurological status. This could indicate a decline in respiratory status or potential complications such as hypoxia or sepsis. Option A, a client who is NPO and has dry mucous membranes, may need intervention but does not indicate an acute change in condition. Option B, a client with rotavirus who has been vomiting, requires assessment and intervention but does not pose an immediate threat to life. Option C, a client with a urinary catheter and cloudy urine, may indicate a urinary tract infection but does not require immediate attention compared to the client with new onset confusion and pneumonia.

Correct Answer: B

Rationale: Limiting the intake of phosphorus-rich foods is appropriate for a client with chronic kidney disease. In individuals with chronic kidney disease, the kidneys cannot filter phosphorus effectively, leading to a buildup in the blood. This can result in bone and heart problems. Therefore, reducing phosphorus intake is crucial to prevent complications. Choices A, C, and D are incorrect. Increasing potassium intake may be harmful as potassium levels can accumulate in the blood with impaired kidney function. Encouraging protein-rich foods may not be suitable as excessive protein intake can strain the kidneys. Advising to increase fluid intake should be done cautiously as individuals with chronic kidney disease may need to restrict fluids based on their stage of the disease.
