Which practice helps prevent urine backflow and potential infection by the drainage bag placement?

• A. Maintain the tubing above the level of the drainage bag.
• B. Keep tubing below the bag level.
• C. Attach to another bag below.
• D. Flush the line with saline daily.

Answer: (A)

Preventing backflow relies on creating a one-way, gravity-driven path for urine from the bladder into the collection bag. Keeping the tubing higher than the drainage bag makes the bag the lowest point in the system, so urine flows downward into the bag and cannot travel back up toward the bladder. This arrangement reduces the chance that bacteria from the bag or tubing will re-enter the urinary tract. In practice, the collection bag should stay below the level of the bladder and be secured to avoid kinks or loops. Other options don’t establish this unidirectional flow, and flushing the line daily doesn’t address the issue of preventing backflow.
