Choice B rationale
Adding promethazine to the allergy list would not be appropriate unless the patient had an allergic reaction to the medication.
Choice C rationale
Continuing to monitor the site would not be the immediate priority action. The nurse should first stop the IV infusion to prevent further damage.
