A nurse is supervising an assistive personnel (AP) who is caring for a client who is at risk for falls. Which of the following actions taken by the AP indicates proper technique for urinary catheter care?

Choice A reason: Keeping the drainage bag above waist level promotes urine backflow, increasing infection risk. Bags must be below bladder level to ensure proper urine flow, so this action is incorrect and unsafe, requiring nurse intervention. Choice B reason: Disconnecting the catheter to empty the bag breaks the closed system, increasing infection risk. The bag should be emptied via the drainage port, so this action is incorrect and requires correction by the nurse. Choice C reason: Emptying the drainage bag when three-quarters full prevents overfilling, reducing backflow and infection risk. This aligns with proper catheter care protocols, ensuring safety for a fall-risk client, making it the correct technique. Choice D reason: Using sterile gloves for emptying the drainage bag is unnecessary, as clean gloves suffice for this non-sterile procedure. Sterile gloves are for catheter insertion, so this action is incorrect and inefficient, requiring guidance.
