The charge nurse observes a new nurse preparing to irrigate an intravenous catheter. The new nurse brought a luer-lock-tipped syringe. Which action should the charge nurse take?

A. While applying povidone to the site is important for aseptic technique, it does not address the immediate concern regarding the use of the luer-lock syringe for irrigation. B. Directing the nurse to attach the luer-lock tip to the irrigation port is the correct action, as luer-lock syringes are designed to provide a secure connection, preventing accidental disconnection during the irrigation process. C. Sending an unlicensed assistive personnel to gather equipment is unnecessary if the new nurse already has the required equipment. D. Using water with 5% dextrose (DW) is not appropriate for irrigating an intravenous catheter; normal saline is the preferred solution.
