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?

Rationale A. Using water with 5% dextrose (DW) is appropriate for irrigating certain types of catheters, especially those that require a non-saline solution to maintain patency. However, the choice of irrigation solution should be based on the specific type of catheter and the facility's policies. It does not directly address the immediate issue of the luer-lock syringe. B. Sending someone else to gather equipment may be necessary in some situations but does not address the current issue of the nurse preparing to irrigate with a luer-lock tipped syringe. This option delays addressing the immediate concern. C. Applying povidone (such as povidone-iodine solution) to the site is a step in the preparation for aseptic technique but does not address the specific issue of the syringe type or the irrigation process itself. D. Luer-lock syringes are commonly used for irrigation purposes because they securely attach to irrigation ports, preventing accidental disconnection during the procedure. Directing the nurse to attach the luer-lock syringe ensures that the irrigation can be performed safely and effectively.
