How often should the cath collection bag be changed?

• A. When it is removed and replaced
• B. Every shift
• C. As needed, no more than half full
• D. Daily

Answer: (C)

The key idea here is to manage the drainage bag so urine flows smoothly while minimizing infection risk. The bag should be emptied as needed and not allowed to become too full. The best practice is to empty it when it’s about half full, and only change the bag for reasons like contamination, damage, or as your facility’s policy dictates. Keeping the bag below bladder level helps prevent backflow into the urinary tract. If you change the bag on a fixed schedule (every shift or daily) or only when it’s removed, you risk unnecessary handling or letting the bag get too full, which can compromise drainage and comfort. So, empty as needed and no more than half full, changing only as necessary.
