A nurse is preparing a client with chronic renal failure for ambulatory peritoneal dialysis. The nurse teaches the client to warm the dialysate before instillation. The rationale behind this action is to:

Prevent hypothermia
Prevent abdominal discomfort
Facilitate vasoconstriction
Prevent pain

Explanation

Answer: B - The dialysate is warmed close to the body temperature in order to prevent abdominal discomfort. Using warm dialysate allows the blood vessels in the peritoneum to dilate, increasing urea clearance and improving the permeability of the peritoneum. A cold dialysate results in vasoconstriction and hypothermia. When warming the dialysate, avoid using the microwave since this could burn the peritoneum.
