A nurse is providing discharge teaching for a client who is to perform peritoneal dialysis at home. Which of the following information should the nurse include?

A. Warming dialysate in a microwave is not recommended due to uneven heating; it should be warmed using a heating pad or warming cabinet. B. Redness at the catheter exit site is a sign of possible infection and should be reported, not expected. C. Pain or discomfort during dialysate inflow is common during the first week as the body adjusts to the process. D. Avoiding high-fiber foods is incorrect; clients are actually encouraged to consume a high-fiber diet to prevent constipation, which can interfere with dialysate flow.
