Which statement about urinary catheter collection bag positioning helps prevent infection?

Keep the bag above the bladder to prevent backflow.

Position has no impact on infection risk.

Keep the collection bag below the bladder to prevent backflow and maintain flow.

Keeping the collection bag below the level of the bladder uses gravity to drain urine away from the body and minimizes backflow into the bladder. Backflow can carry bacteria into the bladder, increasing the risk of a catheter-associated urinary tract infection. Therefore, position the bag lower than the bladder whenever the person is upright and secure it to prevent tugging or kinks, and keep it off the floor. Placing the bag above the bladder or at shoulder height would allow urine to flow back toward the bladder, raising infection risk.

Secure bag at shoulder height.
