A 19-year-old female is stung multiple times by fire ants and reports a known allergy to fire ants but does not carry her epinephrine. What is the most appropriate immediate action?

• A. Advise her to see her physician as soon as possible.
• B. Position her legs well above the level of her heart.
• C. Administer oxygen and transport her to the hospital.
• D. Request a paramedic unit to administer epinephrine.

Answer: (C)

The main idea is that suspected anaphylaxis from insect stings needs immediate airway and breathing support and rapid definitive care. This patient is at high risk for a systemic allergic reaction, and she does not have epinephrine available to treat it right away. Providing high-flow oxygen helps maintain oxygenation if the airways become swollen or breathing becomes labored, and rapid transport ensures she can receive epinephrine and other treatments at the hospital as soon as possible. Elevating the legs doesn’t address the breathing or airway issues and isn’t beneficial here. If a paramedic crew with epinephrine arrives, they can administer it, but with no epinephrine on scene, the best immediate action is to support breathing with oxygen and get her to a facility promptly for definitive care.
