If a person is stung multiple times by wasps and shows signs of swelling and difficulty breathing, what is the appropriate action?

In the case of a person stung multiple times by wasps who is experiencing swelling and difficulty breathing, administering an injection of epinephrine using an autoinjector is the most appropriate action. This is crucial because the symptoms described indicate a potentially severe allergic reaction, known as anaphylaxis. Epinephrine is a life-saving medication that can help reverse the symptoms of anaphylaxis, including swelling in the airway, difficulty breathing, and a decrease in blood pressure.

Epinephrine works by constricting blood vessels, which increases blood pressure and improves circulation, while also relaxing the muscles in the airways to alleviate breathing difficulties. Therefore, having an autoinjector readily available is vital, especially for individuals known to have severe allergies. Quick administration of epinephrine can be lifesaving and should be prioritized before emergency medical services arrive.

Other actions, while they may be relevant in certain contexts, do not address the critical and immediate needs of someone experiencing an anaphylactic reaction. For instance, flooding the eyes, lips, and face with water may not be useful in this scenario and could lead to further distress if airway obstructions persist. Keeping the individual lying down face up is a position that might be appropriate for other medical situations but
