أي إجراء يقلل عدوى القسطرة البولية؟

Which measure reduces catheter-associated urinary infection?

1. Change the catheter routinely every two days
2. Place the bag on the floor to avoid tension on the catheter
3. Disconnect the catheter from the bag at each transfer
4. Keep the drainage system closed and the bag below bladder level

Answer: D) Keep the drainage system closed and the bag below bladder level. A closed system, a bag below the bladder and off the floor, hygiene and early removal all reduce infection.
