What refers to a systemic (whole-body)reaction characterized by breathing difficulty and a dangerous fall in blood pressure? ​

Quizplus · Accepted Answer

Anaphylaxis is a systemic (whole-body) reaction characterized by breathing difficulty and a dangerous fall in blood pressure. It is considered a severe and potentially life-threatening allergic reaction. Hives (A) and oral allergy syndrome (B) are mild allergic reactions that do not typically involve a dangerous drop in blood pressure. Acute allergic response (D) is a general term that can encompass various degrees of allergy symptoms and does not specifically refer to a severe or life-threatening reaction.
