After a sterile catheter touches a non-sterile surface, what should the PCT do?

When a sterile catheter comes into contact with a non-sterile surface, it can no longer be considered sterile. This means that any subsequent use of the catheter could introduce bacteria or other pathogens into the patient's body, increasing the risk of infection. Therefore, to ensure patient safety and maintain sterile technique, the best course of action is to obtain another sterile kit. This ensures that the procedure can continue with equipment that maintains the level of sterility required for safe clinical practice.

Continuing the procedure with a contaminated catheter or attempting to clean it would not sufficiently restore its sterility; both actions can compromise the patient's safety. Similarly, wiping or rinsing the catheter would not eliminate the risk associated with the initial contamination.
