What action is indicated to prevent catheter-associated urinary tract infections (CAUTI)?

• A. Empty drainage bags when they are half full
• B. Remove the catheter as soon as possible
• C. Raise the collection bag above the level of the bladder
• D. Restrict perineal care to once a day

Answer: (B)

Removing the catheter as soon as possible is a primary action indicated to prevent catheter-associated urinary tract infections (CAUTI). Prolonged use of urinary catheters increases the risk of infection, as it provides a pathway for bacteria to enter the bladder. By minimizing the time a catheter is in place, the opportunity for infection is significantly reduced. This practice aligns with guidelines and best practices in healthcare that emphasize judicious use of catheters and prompt removal when they are no longer necessary.

The other options, while they may touch on aspects of catheter care, do not directly address the most effective prevention strategy for CAUTI. For instance, emptying drainage bags when they are half full could help with proper drainage but does not specifically reduce infection risk. Raising the collection bag above the level of the bladder can actually promote backflow of urine, which is counterproductive. Limiting perineal care to once a day may not provide adequate hygiene to prevent infection, as more frequent care is recommended to maintain cleanliness around the catheter site.
