A client with end-stage renal disease (ESRD) is receiving erythropoietin-stimulating agents (ESAs) as part of the dialysis treatment. Which of the following statements by the client indicates an understanding of the medication's purpose?

A) This statement is incorrect. Hypermagnesemia (elevated magnesium levels) can be a concern in ESRD, but it is not a primary indication for initiating dialysis. Magnesium levels can be managed through dietary restrictions and medications without the need for dialysis.

B) This statement is incorrect. Hyperphosphatemia (elevated phosphorus levels) is a common issue in ESRD, but it is not a primary indication for initiating dialysis. Clients with ESRD may receive phosphate binders to control phosphorus levels without necessarily needing immediate dialysis.

C) This statement is incorrect. Hyperkalemia (elevated potassium levels) is a concern in ESRD, but it is not the primary indication described in the scenario. While hyperkalemia may occur with fluid overload, the primary concern in this case is the hypervolemia and its associated symptoms.

D) Hypervolemia (severe fluid overload) is a critical indication for initiating dialysis in clients with end-stage renal disease. Dialysis helps remove excess fluid from the body and can relieve symptoms such as pulmonary edema and hypertension.

A. Incorrect. Warming the dialysate fluid to body temperature before instilling it into the peritoneal cavity is a standard procedure in continuous ambulatory peritoneal dialysis (CAPD. .

B. Correct. Performing the exchanges in a clean, dry environment free from pets is crucial to prevent contamination and reduce the risk of infection during CAPD.

C. Incorrect. Using tap water to cleanse the catheter insertion site before the exchange is not recommended. The catheter exit site should be cleaned with an appropriate antiseptic solution as instructed by the healthcare provider.

D. Incorrect. While daily dressing changes are important, using sterile technique for catheter dressing changes may not be necessary, as the dressing does not directly contact the peritoneal cavity during CAPD exchanges.
