Question

Quizplus · Accepted Answer

Anaphylaxis is a systemic allergic reaction that can occur after exposure to an allergen such as a bee sting. Symptoms can range from mild (such as hives) to severe (such as difficulty breathing and shock) and can be life-threatening if not treated immediately. Hemolytic shock (A) is not a type of hypersensitivity reaction, but a severe form of shock caused by the destruction of red blood cells. Necrotizing vasculitis (C) is a type of inflammation that affects blood vessels, but is not directly related to allergies or bee stings. Systemic erythematosus (D) refers to a group of autoimmune diseases, and is not related to bee sting allergies.
