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. Clamp the catheter above the specimen port is incorrect. During closed intermittent irrigation, clamping is not necessary above the specimen port. Clamping the catheter incorrectly can increase intravesical pressure and risk bladder trauma or infection. B. Inject the irrigation solution slowly into the catheter is correct. Slow instillation of sterile irrigation solution helps prevent sudden increases in bladder pressure, reduces discomfort, and minimizes the risk of trauma to the bladder mucosa. Closed intermittent irrigation is performed to maintain catheter patency while reducing infection risk, and slow injection ensures safe administration. C. Use a 3-mL syringe to perform the catheter irrigation is incorrect. Catheter irrigation usually requires a larger syringe (30–60 mL) to allow adequate fluid flow for flushing the catheter. A 3-mL syringe is too small and ineffective for proper irrigation. D. Place the client in the Trendelenburg position is incorrect. The Trendelenburg position (head lower than feet) is not required for bladder irrigation and may cause discomfort or respiratory compromise. The client should be supine or in a comfortable position that allows easy access to the catheter.
