An adult male patient who is receiving peritoneal dialysis asks the nurse why a solution is being warmed to body temperature before it is instilled in peritoneal cavity. The nurse should state that it is to:
  1. Encourage removal of serum urea by preventing constriction of peritoneal blood vessels
  2. Force Potassium back into the cells, thereby decreasing serum levels
  3. Add extra warmth to the body because metabolic processes are disturbed
  4. Help prevent cardiac dysryhthmias by speeding up removal of excess potassium
Explanation
Answer - A - The nurse should state that it is to encourage removal of serum urea by preventing constriction of peritoneal blood vessels. It promotes vasodilation so that urea can be shifted from the blood into the dialyzing solution since the urea is a large molecular substance.
