Question

J.E., a 37-year-old woman with no prior history of allergies, was working in her yard when she received a sting on the right wrist from a yellow-jacked wasp. Several minutes later she complained of a itching sensation and cramping abdominal pains. She then became acutely short of breath with wheezing. A patchy erythema radiating from the area of the sting was noted along with swollen eyelids and lips. A neighbor took her to the hospital where she became very faint and could not talk or provide information to assist with a diagnosis. Vital signs were as follows: BP of 60/34; Pulse of 156; Respiration rate of 40

Epinephrine 1/1000 was administered IM along with 100 mg of hydrocortisone. Within minutes, an improvement in the respiratory rate was noted and blood pressure increased to 100/70 with a pulse of 112.
