Certified Nursing Assistant Exam Prep

Answer: B - The bag should hang from the bed frame, chair, or wheel chair. It must not touch the floor. The bag is always kept lower than the client’s bladder. If the drainage bag is higher than the bladder, urine can flow back into the bladder and an infection can occur. Therefore, do not hang the drainage bag on a bed rail. When the bed rail is raised, the bag is higher than the bladder level. When the person walks, the bag is held lower than the bladder. Emptying of the drainage should be done every six to eight hours to prevent proliferation of microbes, which can develop into infection. The tubing should not have dependent loops to prevent stasis of urine in the tubes, which can promote backflow to the bladder.
