GENITO-URINARY SYSTEM DISORDERS – DIALYSIS

A nurse is educating a client about the different types of dialysis. The client asks which type of dialysis uses the peritoneal membrane as a filter. Which of the following responses by the nurse is accurate? A. "Hemodialysis uses the peritoneal membrane as a filter." B. "Continuous ambulatory peritoneal dialysis (CAPD) uses the peritoneal membrane as a filter." C. "Automated peritoneal dialysis (APD) uses the peritoneal membrane as a filter." D. "Peritoneal dialysis does not use the peritoneal membrane as a filter." Explanation 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.
