A client with end-stage renal disease (ESRD) is receiving heparin during hemodialysis to prevent clotting in the dialyzer. Which of the following laboratory values should the nurse monitor closely while the client is receiving heparin?

A. Protein intake is generally encouraged for clients on hemodialysis to prevent malnutrition and replace losses during dialysis.
B. Sodium should be limited because excess intake can lead to fluid retention, hypertension, and increased workload on the heart.
C. Calcium intake is typically monitored but not universally restricted unless prescribed; limiting calcium is not a primary dietary recommendation.
D. Iron is often supplemented to prevent anemia associated with chronic kidney disease and dialysis.

A)This statement is incorrect. Hemodialysis does not use the peritoneal membrane as a filter. Hemodialysis involves the use of a machine that filters the blood outside the body, not the peritoneal membrane.

B) This statement is incorrect. Continuous ambulatory peritoneal dialysis (CAPD) uses the peritoneal membrane as a filter during manual exchanges of dialysate fluid, not with a machine like automated peritoneal dialysis (APD).

C) This statement is accurate. Automated peritoneal dialysis (APD) uses a machine to perform exchanges of dialysate solution through the peritoneal membrane.

D) This statement is incorrect. Peritoneal dialysis uses the peritoneal membrane as a filter. It involves the instillation and drainage of dialysate fluid into the abdominal cavity through a catheter.
