Final answer:
For a bee sting, apply baking soda to the affected area unless the person is allergic, in which case use an epinephrine auto-injector if severe allergic reaction symptoms occur.
Step-by-step explanation:
When an individual is stung by a bee, the first aid depends on their allergy status. For those not allergic, applying a paste of baking soda (sodium bicarbonate) to the stung area is a common first-aid treatment that can alleviate itching and swelling. However, if the person is allergic and experiences symptoms of a systemic allergic reaction, they may need an epinephrine auto-injector, such as an EpiPen, which counters the severe drop in blood pressure and other anaphylactic symptoms. Sensitive individuals should always carry an epinephrine auto-injector in case of a bee sting. In the absence of severe allergic reactions, first aid includes removing the stinger, cleaning the area, and using baking soda to reduce discomfort.
