A patient has an indwelling urinary catheter. Which action best reduces the risk of catheter-associated urinary tract infection?
Correct answer: B. Keeping the drainage bag below bladder level
- A. Disconnecting the tubing to measure urine separately
- B. Keeping the drainage bag below bladder level
- C. Clamping the catheter every two hours
- D. Placing the drainage bag on the floor
Explanation
The drainage bag stays below bladder level so urine does not flow back into the bladder. The closed system should remain intact, and the bag must not touch the floor because both actions increase infection risk.
