2) Pain in chest, rapid pulse, pallor, sweating
3) Decreased BP strong pulse, heavy breathing

Answer 1

The signs of an anaphylactic severe allergic reaction include decreased blood pressure, swelling, and difficulty breathing, necessitating immediate treatment with an epinephrine autoinjector.

Step-by-step explanation:

The signs of a severe allergic reaction, or anaphylaxis, include a combination of symptoms that can rapidly become life-threatening. These symptoms include a decrease in blood pressure (hypotension), marked swelling that can affect various parts of the body including the tongue and throat, difficulty breathing due to airway constriction, and changes in heart rate. When someone experiences an anaphylactic reaction, it is critical to administer emergency treatment immediately, which often involves the use of an epinephrine autoinjector (EpiPen®) to counteract the effects of the allergic response until proper medical care can arrive.
