A nurse is caring for a client who has an indwelling urinary catheter. Which of the following actions should the nurse take when performing a closed intermittent irrigation?

A. Inject the irrigation solution slowly into the catheter: Slowly injecting the irrigation solution prevents sudden increases in bladder pressure, reduces discomfort, and ensures effective clearance of clots or debris. Gentle administration is essential for maintaining the integrity of the bladder and catheter system. B. Place the client in the Trendelenburg position: The Trendelenburg position is not recommended for routine closed intermittent catheter irrigation. Placing the client in this position can increase the risk of reflux or discomfort and is not necessary for effective irrigation. C. Clamp the catheter above the specimen port: Clamping the catheter above the specimen port is not appropriate because it can obstruct flow and increase the risk of backflow or bladder distention. The irrigation should be performed using the designated irrigation port while maintaining a closed system. D. Use a 3-mL syringe to perform the catheter irrigation: A 3-mL syringe is too small for effective bladder irrigation. Typically, a larger syringe (e.g., 30–50 mL) is used to ensure adequate flow of the irrigation solution and clearance of debris without excessive pressure.
