While inserting an indwelling urinary catheter into a female client, the nurse observes urine flow in the tubing. Which action should be taken next?

A. Inflate the balloon with 5 mL of sterile water: Inflating the catheter balloon before ensuring the catheter is fully inside the bladder can cause trauma to the urethra or result in the balloon being inflated in the urethra, leading to pain, obstruction, and potential injury. Balloon inflation should only occur once proper placement is confirmed. B. Ask the client to breathe deeply and slowly exhale: Deep breathing can help relax the urethral sphincter and ease catheter insertion. However, at the point when urine is already observed flowing, the catheter has not yet reached its optimal position in the bladder, so this step is no longer the priority. C. Insert the catheter an additional inch (2.5 cm): Observing urine flow indicates that the catheter has reached the bladder, but the tip may not be fully inside. Advancing the catheter slightly ensures that the balloon is positioned entirely within the bladder before inflation, preventing urethral trauma and securing proper catheter placement. D. Document the color and clarity of the urine: While documenting urine characteristics is part of nursing care, this step is secondary to confirming proper catheter placement. Accurate placement is essential to prevent complications and is prioritized before documentation.
