A nurse is providing education to a client who will be starting peritoneal dialysis. The client asks, "How does peritoneal dialysis work?" Which of the following responses by the nurse is accurate?
"Peritoneal dialysis uses a machine to filter blood outside of your body."
"Peritoneal dialysis involves the removal of the peritoneal membrane to filter waste."
"Peritoneal dialysis uses the peritoneal membrane in your abdomen to filter waste."
"Peritoneal dialysis requires a catheter to be inserted into your bladder to remove toxins."
The Correct Answer is C
A) This statement is incorrect. Peritoneal dialysis does not use a machine to filter blood outside of the body; that description is characteristic of hemodialysis.
B) This statement is incorrect. Peritoneal dialysis does not involve the removal of the peritoneal membrane; instead, it uses the peritoneal membrane in the abdomen to filter waste.
C) This statement is accurate. Peritoneal dialysis uses the peritoneal membrane in the abdomen as a semipermeable membrane to filter waste products and excess fluids from the blood.
D) This statement is incorrect. Peritoneal dialysis does not require a catheter to be inserted into the bladder. Instead, it uses a catheter to infuse and drain dialysate into and out of the peritoneal cavity.
