You and your partner Amy arrive on scene to find a woman with hives over much of her body. She is wheezing and complaining of difficulty breathing. Her husband says she was stung by a hornet and has no prior history of allergies. What would be the best course of action?

Based on the scenario being described within the question it can be said that the best course of action would be to place a high flow of O2 and rapid transportation if the patient appears to be going into anaphylaxis. Mainly because this is a severe life threatening allergic reaction, that occurs at a moments notice and closes the individuals airway causing breathing to become very difficult.
