Which practice best reduces catheter occlusion and infection risk?

• A. Keep Drainage System Open
• B. Disconnect Frequently
• C. Secure Catheter But Leave System Open
• D. Maintain a Closed Drainage System, Secure the Catheter, and Avoid Unnecessary Disconnections

Answer: (D)

Maintaining a closed drainage system with the catheter secured and avoiding unnecessary disconnections minimizes both infection risk and occlusion. Keeping the system closed prevents ambient bacteria from entering the urinary tract and reduces backflow and contamination that can lead to infection. Securing the catheter decreases movement and urethral trauma, which helps prevent kinking or displacement that can block flow. Avoiding unnecessary disconnections keeps the sterile pathway intact, preventing air and contaminants from entering the system and reducing opportunities for occlusion. This integrated approach directly lowers the chances of catheter-associated infection and blockage, making it the best practice.
