In CAPD, which action is performed immediately after draining the dialysate?

• A. Disconnect and seal the catheter.
• B. Re-infuse fresh dialysate immediately.
• C. Start a new infusion without disconnecting.
• D. Perform exit-site care first before disconnecting

Answer: (A)

After draining the dialysate, the system must be closed to keep things sterile and prevent contamination or air entry. Disconnecting the tubing from the catheter and sealing the catheter accomplishes this, preserving a closed, safe pathway for the next step of the cycle.

Starting a new infusion or reinfusing immediately would break the closed system and risks introducing contaminants or air. Exiting-site care is important but is typically done after the disconnection to maintain proper sterile technique and minimize infection risk.
