What is one method to maintain a closed system in catheter use?

Maintaining a closed system in catheter use is crucial for reducing the risk of infections. Keeping the catheter connected to the drainage bag is essential because it prevents the introduction of pathogens that can occur when disconnecting the system. A closed system minimizes exposure to outside contaminants, thereby enhancing the sterility of the urinary tract and reducing the incidence of catheter-associated urinary tract infections (CAUTIs).

In catheter management, it is important to have a continuous connection that ensures consistent drainage without interruption. This practice is vital for ensuring that the system remains closed and free from infection risks associated with disconnection, such as contamination from the environment.

Other options suggest actions that could compromise the sterile environment. For instance, routinely disconnecting the catheter or changing the drainage bag daily could potentially introduce pathogens into the system, counteracting the benefits of having a closed system.
