A nurse is changing the dressing for a client who is receiving peritoneal dialysis. Which of the following actions should the nurse take?

A. The catheter site should be cleansed using a circular motion, starting at the exit site and moving outward, not a side-to-side motion, to prevent introducing microorganisms. B. Taping down only the corners does not adequately secure the dressing. All edges should be sealed to reduce the risk of infection. C. Placing a mask on the client (and the nurse) during dressing changes helps prevent contamination of the peritoneal catheter site, which is highly susceptible to infection. This is an essential aseptic practice. D. An occlusive dressing is not typically recommended over peritoneal dialysis catheter sites, as it can trap moisture and increase the risk of infection. A sterile gauze dressing is generally preferred.
