Ten minutes following administration of an antibiotic, the nurse assesses a patient to have edematous lips, hoarseness, and expiratory stridor
Vital signs assessed by the nurse include blood pressure 70/40 mm Hg, heart rate 130 beats/min, and respirations 36 breaths/min. What is the priority intervention? a. Diphenhydramine (Benadryl) 50 mg intravenously
b. Epinephrine 3 to 5 mL of a 1:10,000 solution intravenously
c. Methylprednisolone (Solu-Medrol) 125 mg intravenously

B
The patient is exhibiting signs of anaphylaxis. For anaphylaxis with hypotension, epinephrine 0.3 to 0.5 mg (3 to 5 mL of 1:10,000 solution) is administered intravenously. Diphenhydramine (Benadryl) will help block histamine release, but epinephrine is the drug of choice for anaphylaxis with hypotension. Corticosteroids, such as methylprednisolone (Solu-Medrol), are used to reduce inflammation, but epinephrine is the drug of choice for anaphylaxis with hypotension. Ranitidine (Zantac) will help block histamine release, but epinephrine is the drug of choice for anaphylaxis with hypotension.
