Final answer:
To discontinue IV fluids and catheter, the nurse should turn off the IV pump, occlude the IV tubing, remove the tape securing the catheter, and apply pressure over the catheter insertion site.
Step-by-step explanation:
When preparing to discontinue the IV fluids and catheter, the nurse should plan to take the following actions in this order:
First, (b) turning off the IV pump is essential to cease fluid administration.
Next, (c) occluding the IV tubing prevents any residual fluid from entering the catheter.
Subsequently, (d) applying pressure over the catheter insertion site minimizes bleeding upon removal.
Finally, (a) removing the tape securing the catheter allows for gentle extraction.
This sequential process ensures a safe and efficient removal, prioritizing the child's comfort and minimizing the risk of complications associated with catheter removal in pediatric patients.
