Answer 1

Anaphylaxis is a severe allergic reaction characterized by respiratory distress, a significant drop in blood pressure, and potential airway obstruction, which can be fatal if not treated promptly with epinephrine.

Step-by-step explanation:

Anaphylaxis is a rapid, systemic, and potentially life-threatening allergic reaction. It is considered a type I hypersensitivity reaction that can be caused by certain allergens such as foods (like shellfish and peanuts), insect stings, medications (like penicillin), or other substances. The life-threatening symptoms of anaphylaxis include respiratory distress, plummeting blood pressure (anaphylactic shock), swelling of the tongue and throat that can obstruct the airway leading to suffocation, and without immediate treatment, it can result in loss of consciousness, coma, or death. Treatment for anaphylaxis typically involves the immediate administration of epinephrine which is available in devices like EpiPen®, to constrict blood vessels, relax bronchial smooth muscles, and stabilize heart rate. Epinephrine serves as an emergency measure to control the immune reaction until professional medical care is accessible.
