When assessing a client with an indwelling urinary catheter

• A. The drainage bag is kept below bladder level at all times
• B. The clamp on the urinary drainage bag is open
• C. The catheter is removed to check patency
• D. The keeper is secured to the bedrail

Answer: (B)

Opening the clamp on the drainage bag is essential because it allows urine to flow from the bladder into the collection bag. If the clamp is closed, drainage stops, which can cause bladder distension, discomfort, and raise the risk of infection. While keeping the bag below the level of the bladder helps prevent backflow, the immediate action during assessment to ensure proper drainage is to ensure the clamp is open. Removing the catheter to check patency or securing the keeper to a bedrail are not appropriate during routine assessment and can cause harm or tether the system in unsafe ways.
