Final answer:
The charge nurse should instruct the new nurse to use a transparent dressing over the IV site, as it allows visibility and better infection control than a 4x4 sterile gauze dressing.
Step-by-step explanation:
The correct action that the charge nurse should take is to instruct the new nurse to use a transparent dressing over the IV site. A transparent dressing allows for continuous visibility of the IV site for monitoring for signs of infection, inflammation, or other complications. It also allows the site to remain clean and dry, which is essential in preventing infection. While a 4x4 sterile gauze can be used to control bleeding during the insertion, it is not typically used to secure and cover the IV site after the catheter has been placed.
Using a checklist and confirming the preparedness of all required supplies and proper procedures, as proposed by Dr. Pronovost, ensures that each step is followed correctly to maintain sterility and patient safety. This practice also enables other members of the healthcare team, including nurses, to observe the procedures and speak up if any step is missed or not correctly performed.
