Question 4 of 5

A female client has been diagnosed with chronic renal failure. She is a candidate for either peritoneal dialysis or hemodialysis and must make a choice between the two. Which information should the nurse give her to help her decide?

Correct Answer: A

Rationale: Hemodialysis is faster in clearing the blood of toxins than peritoneal dialysis. However, clients must consider the time that they spend traveling to the dialysis center and the disruption in their daily lives. Peritoneal dialysis requires several exchanges with dwelling time for the dialysate and therefore takes longer than hemodialysis. Several serious complications of peritoneal dialysis include peritonitis, catheter displacement and/or plugging, or pain during dialysis. A client can be taught to self-administer peritoneal dialysis without the aid of a professional.
