A client with chronic renal failure is prescribed calcitriol (active form of vitamin D. to manage calcium and phosphate levels. The client asks the nurse about the purpose of this medication. How should the nurse respond?

A. Incorrect. Encouraging the client to drink 3 liters of fluid daily may be excessive and can contribute to fluid overload in individuals on hemodialysis. Fluid intake needs to be limited and closely monitored.

B. Correct. Monitoring the vascular access site is crucial to detect early signs of infection or clotting, which can lead to serious complications such as sepsis or thrombosis.

C. Incorrect. Phosphate binders are used to control phosphate levels in the blood and are generally taken with meals, not specifically before hemodialysis sessions.

D. Incorrect. Promoting a high-potassium diet is not appropriate for individuals on hemodialysis, as it can lead to hyperkalemia. Clients on hemodialysis typically need to restrict potassium intake.

A. Incorrect. Dairy products are high in potassium and should be limited in clients at risk for hyperkalemia.

B. Incorrect. Fruits and vegetables are also high in potassium and should be limited in clients with chronic renal failure and hyperkalemia risk.

C. Correct. Nuts and seeds are rich sources of potassium and should be restricted in the diet of clients at risk for hyperkalemia.

D. Incorrect. Poultry is a good protein source, but the type of protein is not the main concern for clients at risk for hyperkalemia; it is the overall potassium content of the diet that needs to be reduced.
