The charge nurse observes a new nurse preparing to insert an intravenous (IV) catheter. The new nurse has gathered supplies, including intravenous catheters, an intravenous insertion kit, and a 4x4 sterile gauze dressing to cover and secure the insertion site. Which action should the charge nurse take?

A. Plan to observe the secured IV site after the insertion procedure. This is a proactive step, but it does not address the immediate need to correct the new nurse’s choice of dressing. B. Remind the nurse to tape the gauze dressing securely in place. While securing the dressing is important, it is not the best practice to use a gauze dressing for IV sites as it obscures the view of the insertion site. C. Confirm that the nurse has gathered the necessary supplies. Confirming supplies is important, but this does not address the incorrect dressing choice. D. Instruct the nurse to use a transparent dressing over the site. This is the correct answer because a transparent dressing allows for continuous visual inspection of the IV site for signs of infection or infiltration, which is crucial for patient safety.
