Answer:
The correct answer is B. anaphylactic shock.
Foods, medications, and insects are common triggers for anaphylactic shock. Anaphylactic shock is a severe and potentially life-threatening allergic reaction. When a person with a hypersensitivity to certain allergens comes into contact with them, it can trigger a rapid immune response. This immune response causes the release of large amounts of histamine and other chemicals, leading to a systemic allergic reaction. The symptoms can be sudden and severe, affecting multiple systems in the body, including the respiratory, cardiovascular, and gastrointestinal systems. Common manifestations of anaphylactic shock include difficulty breathing, swelling of the throat or tongue, hives, dizziness, low blood pressure, and gastrointestinal distress. Immediate medical attention is crucial in this situation, as anaphylactic shock can progress rapidly and requires treatment with epinephrine (adrenaline) and emergency medical care.
