T/F: anaphylaxis is only systemic
F: it can be both systemic (shock, difficulty breathing, and potentially fatal) and localized (hives and hay fever)
True. Anaphylaxis is a severe and potentially life-threatening allergic reaction that is typically systemic, meaning it affects multiple organs and tissues throughout the body. It is characterized by a sudden onset of symptoms, which can include hives or swelling, difficulty breathing, low blood pressure, and gastrointestinal problems. In some cases, anaphylaxis may initially present with symptoms that are localized to a certain area of the body (such as the skin or respiratory system), but it typically progresses rapidly and becomes more widespread.
