Which of the following strategies has been demonstrated to reduce the incidence of CAUTI (catheter-associated UTI)?

• A. Provide meatal care with an antibacterial soap and ointment twice daily and as needed.
• B. Irrigate the bladder through the catheter port with 30mL acetic acid weekly.
• C. Change the catheter every 2 weeks.
• D. Maintain the tubing in the proper position above the level of the drainage bag.

Answer: (D)

Preventing CAUTI mainly involves keeping the urinary drainage system closed and ensuring urine drains away from the bladder by gravity into the collection bag. When the tubing is kept in a proper position with the drainage bag below the level of the bladder, urine flows downward and cannot easily travel back toward the bladder. This setup helps maintain a closed system and reduces the chance for microbes to ascend the catheter, which lowers infection risk. Other practices listed don’t have demonstrated benefits for reducing CAUTI and may introduce risks: cleaning the meatus with antibacterial soap and ointment, irrigating the bladder through the catheter, or changing the catheter on a set schedule aren’t reliable infection-prevention strategies. The essential protective measure is keeping the tubing arranged so the bag stays below the bladder level, preserving a closed drainage path and minimizing backflow.
