What indicates a nursing student requires further teaching regarding IV dressing changes?

Using a povidone-iodine swab and not allowing it to dry before applying a new dressing signifies a misunderstanding of infection control principles in IV therapy. The effectiveness of antiseptic solutions, such as povidone-iodine, relies on adequate drying time to ensure that the skin is properly disinfected before a new dressing is applied. If the solution has not dried, it may not provide the intended antimicrobial effect, potentially increasing the risk of infection at the IV site.

The other actions demonstrated by the student—using sterile gloves when removing the old dressing, documenting symptoms at the insertion site, and appropriately cleaning the insertion site with CHG solution—indicate a sound understanding of infection control protocols and proper procedural techniques in IV therapy management. These practices are critical for maintaining patient safety and reducing the chances of complications associated with IV access.
