A nurse is educating a client about the different types of dialysis. The client asks which type of dialysis uses the peritoneal membrane as a filter. Which of the following responses by the nurse is accurate?
"Hemodialysis uses the peritoneal membrane as a filter."
"Continuous ambulatory peritoneal dialysis (CAPD) uses the peritoneal membrane as a filter."
"Automated peritoneal dialysis (APD) uses the peritoneal membrane as a filter."
"Peritoneal dialysis does not use the peritoneal membrane as a filter."
The Correct Answer is C
A)This statement is incorrect. Hemodialysis does not use the peritoneal membrane as a filter. Hemodialysis involves the use of a machine that filters the blood outside the body, not the peritoneal membrane.
B) This statement is incorrect. Continuous ambulatory peritoneal dialysis (CAPD) uses the peritoneal membrane as a filter during manual exchanges of dialysate fluid, not with a machine like automated peritoneal dialysis (APD).
C) This statement is accurate. Automated peritoneal dialysis (APD) uses a machine to perform exchanges of dialysate solution through the peritoneal membrane.
D) This statement is incorrect. Peritoneal dialysis uses the peritoneal membrane as a filter. It involves the instillation and drainage of dialysate fluid into the abdominal cavity through a catheter.

Correct Answer is D
Explanation
A) This statement is incorrect. Infection is not a rare complication of peritoneal dialysis. It is a common risk that requires proactive measures to prevent.
B) This statement is incorrect. While infections can occur and may be treatable with antibiotics, it is essential to focus on prevention and maintaining aseptic technique.
C) This statement is incorrect. Taking antibiotics regularly to prevent infection is not the standard practice for clients on peritoneal dialysis. Antibiotics are typically prescribed to treat infections when they occur, not as a preventive measure.
D) This statement is accurate. Infection is a significant risk for clients on peritoneal dialysis due to the direct access to the peritoneal cavity through the catheter. Strict aseptic technique is crucial to prevent infections.
Correct Answer is A
Explanation
A. Correct. Using the arm with the AV fistula for blood pressure measurements can compress the vascular access and compromise blood flow. It is important to avoid using the fistula arm for blood pressure measurements and venipuncture.
B. Incorrect. The AV fistula should not be used for intravenous catheter insertion to prevent potential damage and infection to the access site.
C. Incorrect. Self-cannulation of the AV graft is typically performed by healthcare professionals, and clients should not attempt to self-cannulate their vascular access.
D. Incorrect. If an AV fistula starts bleeding, the client should not apply pressure to the site. Instead, they should immediately elevate the arm and apply pressure to the bleeding site with a clean cloth or bandage while seeking medical attention.
