The charge nurse observes a new nurse preparing to irrigate an intravenous catheter. The new nurse is attaching an 18-gauge needle. Which action should the charge nurse take?

A. Suggesting the antecubital site does not address the immediate issue of using an inappropriate needle size. B. Sending a UAP to gather equipment is not an immediate action needed to correct the mistake. C. Using an 18-gauge needle to irrigate an IV catheter is inappropriate and could damage the catheter. The charge nurse should instruct the new nurse to remove the needle and use a syringe without a needle to perform the irrigation safely. D. Starting a secondary infusion is unrelated to the irrigation process and does not correct the inappropriate needle use.
