Which practice verifies proper tubing connections during each PD exchange?

• A. Reuse old connectors to save costs
• B. Avoid touching contaminated surfaces during connections
• C. Use clean, dry connections and verify sterile connectors are used
• D. Disconnect and reassemble without hand hygiene

Answer: (C)

Maintaining aseptic technique during every PD exchange is essential to prevent infection. The best practice is to use clean, dry connections and verify that sterile connectors are used, because moisture or non-sterile parts can introduce bacteria into the peritoneal cavity. Ensuring the connection points are sterile creates a reliable barrier and protects the peritoneal space from contamination. Reusing old connectors violates sterility and increases infection risk, while handling via contaminated surfaces or skipping hand hygiene would also compromise the connection. In short, using clean, dry, and sterile components and confirming sterility at the connection point directly supports safe, effective exchanges.
