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.

Correct Answer is D
Explanation
A) This statement is incorrect. Cloudy dialysate drainage may indicate infection or peritonitis, and the nurse should not simply document the finding and continue monitoring without further assessment.
B) This statement is incorrect. Administering an antibiotic medication without a definitive diagnosis is not appropriate. The nurse should assess the client further to determine the cause of the cloudy drainage.
C) This statement is incorrect. Increasing the dialysis exchange frequency would not address the issue of cloudy dialysate drainage and may not be indicated without a proper assessment.
D) This statement is correct. Cloudy dialysate drainage may indicate infection or peritonitis. The nurse should check the client's vital signs and assess for signs of abdominal pain or tenderness, as this requires immediate evaluation.
Correct Answer is B
Explanation
A. Incorrect. Increasing the dialysate temperature can lead to vasodilation and potentially exacerbate hypotension during dialysis.
B. Correct. Limiting fluid removal during dialysis is essential to prevent excessive fluid loss, which can cause hypotension and potentially lead to intradialytic hypotension.
C. Incorrect. Encouraging a high-sodium diet is not the primary intervention to prevent dialysis-related hypotension. It may be recommended for some clients to manage hyponatremia, but fluid management is more critical.
D. Incorrect. Administering intravenous hypertonic saline during dialysis is not a routine intervention to prevent hypotension. It may be used in specific cases, but fluid management is the primary approach.
