A nurse is reviewing the GFR calculation for a client with chronic renal failure. The client's serum creatinine level is 2.5 mg/dL. What should the nurse do next?

A. Incorrect. Applying compression stockings may help reduce swelling but does not address the underlying cause. Additionally, compression stockings should not be used if the client has arterial insufficiency.

B. Incorrect. Elevation may provide temporary relief from swelling, but it does not address the underlying cause of fluid retention

in chronic renal failure.

C. Correct. The nurse should measure the client's blood pressure and pulse rate to assess for fluid overload and possible hypertension, which can be associated with chronic renal failure.

D. Incorrect. Assessing the client's daily protein intake is not the priority when the client presents with swelling in the ankles and legs. Fluid retention is a more immediate concern that requires assessment and intervention.

A. Correct. Touching the dialysis catheter site increases the risk of infection, and clients receiving peritoneal dialysis must practice meticulous catheter care to minimize this risk.

B. Incorrect. While daily weight monitoring is essential for clients on peritoneal dialysis, it is not specifically related to peritoneal dialysis care.

C. Incorrect. Peritoneal dialysis is a home-based treatment, and the client performs the dialysis exchanges themselves. There is no need for frequent visits to the dialysis center.

D. Incorrect. Pain medication is not typically needed before starting a peritoneal dialysis exchange, as the procedure itself is not painful. Proper technique and sterile care are the main focus of peritoneal dialysis education.
