The nurse initiates an I.V. infusion of piperacillin-tazobactam. The patient soon complains of shortness of breath, pruritis, and hives. Which of the following should the nurse do first?

Administer epinephrine as ordered


•The nurse's first priority is always assessing the patient's airway. However, looking closer at this scenario, the patient is able to talk to the nurse, therefore, the airway must be patent. The nurse should then recognize that the patient is having a anaphylactic reaction and administer epinephrine as ordered.

•Diphenhydramine  should be given if the patient is having a mild allergic reaction.

•Blood pressure should be monitored, but after the immediate threat is handled.
