In order to prevent urine from backflowing into the bladder, drainage bags from an indwelling Foley catheter should be kept below the the level of the bladder. It also allows gravity to assist in draining the tubing. Checked that the tubing is not kinked or compressed. Depending on the reason for the catheter, urine may have an unusual appearance; ask the nurse what is abnormal for the patient. Monitor and record the color of the urine, as well as observations such as sediment, cloudiness, or blood. Follow your facility’s policy or the patient’s care plan regarding how often to change the urinary drainage bag.
