A nurse is caring for a client with chronic renal failure who is prescribed phosphate binders. What is the rationale for administering phosphate binders to this client?
To reduce calcium absorption and prevent kidney stone formation.
To decrease phosphate levels and prevent hyperphosphatemia.
To improve iron absorption and manage anemia.
To increase potassium excretion and prevent hyperkalemia.
The Correct Answer is B
A. Incorrect. Phosphate binders are not used to reduce calcium absorption. They are specifically prescribed to control phosphate levels in the blood.
B. Correct. Phosphate binders are medications that bind to dietary phosphorus in the digestive tract, preventing its absorption and reducing phosphate levels in the blood. This helps manage hyperphosphatemia, a common complication in chronic renal failure.
C. Incorrect. Phosphate binders do not improve iron absorption or manage anemia. They are not related to iron metabolism.
D. Incorrect. Phosphate binders do not affect potassium excretion. They are specific to phosphate control in the body and do not impact potassium levels.

Correct Answer is C
Explanation
A. Incorrect. Encouraging the client to drink more fluids may not immediately resolve the cloudy dialysate drainage. The nurse needs to assess the client's dialysis technique and the potential cause of the cloudiness.
B. Incorrect. Administering intravenous antibiotics is not the initial intervention for cloudy dialysate drainage. First, the nurse should assess the client's technique and position during dialysis.
C. Correct. Cloudy dialysate drainage may indicate improper dialysate exchange, infection, or other complications. The
nurse should first assess the client's dialysis technique and ensure proper positioning to identify the cause.
D. Incorrect. Discontinuing peritoneal dialysis should be considered if there is clear evidence of infection or other serious complications, but it is not the initial intervention for cloudy drainage without further assessment.
Correct Answer is B
Explanation
A. Incorrect. Pruritus (itching) is a common symptom of chronic renal failure and is related to the buildup of waste products and toxins in the blood, leading to skin irritation.
B. Correct. Pruritus is a common and distressing symptom of chronic renal failure, caused by the retention of uremic toxins in the blood. These toxins can irritate the skin and lead to itching.
C. Incorrect. While medications can sometimes cause pruritus as a side effect, it is not the primary cause of itching in clients with chronic renal failure.
D. Incorrect. Persistent pruritus in a client with chronic renal failure is not necessarily indicative of an allergic reaction to medications. It is more likely related to the buildup of waste products in the blood.
