The importance of keeping the catheter drainage bag below the level of the bladder is crucial for preventing backflow of urine, which can lead to potential urinary tract infections (UTIs) and other complications. When the drainage bag is positioned correctly, it ensures that urine flows freely from the bladder through the catheter and into the bag, minimizing the risk of infection and promoting proper urinary function. Maintaining this position is a fundamental aspect of catheter care that enhances the health and comfort of the resident.

Securing the catheter to the leg should not be excessively tight, as this can cause discomfort and impair circulation. Frequent emptying of the catheter bag is necessary; however, doing it once per shift may not be adequate, as the bag could fill up sooner, leading to overflow. Changing the catheter should follow specific medical protocols and timing, rather than convenience, to maintain hygiene and care standards.
