What are the two most common routes of CVC infection?

The correct choice indicates that migration and contamination are the two most common routes of central venous catheter (CVC) infection. Migration refers to the movement of the catheter within the body, which can potentially introduce pathogens from the skin or surrounding tissues into the bloodstream, especially when the catheter is not properly secured. Contamination involves the introduction of bacteria or other pathogens onto the catheter itself or through the insertion site, often due to improper aseptic techniques during catheter placement or maintenance.

These routes highlight the importance of maintaining sterile conditions and monitoring catheter care to prevent infections, which are serious complications associated with the use of CVCs. Understanding these mechanisms assists healthcare providers in implementing appropriate infection control practices and enhances patient safety.
