一位 25 歲女性在野外被蜜蜂螫後 5 分鐘內發生過敏性休克：喉嚨腫脹、喘息、嘴唇舌頭血管性水腫、全身蕁麻疹並失去意識。優先介入為何？
A 25-year-old female develops anaphylaxis after a bee sting in the woods—throat swelling, gasping, lip and tongue angioedema, generalized urticaria, and loss of consciousness within 5 minutes. What is the priority intervention?
- AAdminister a full dose of intramuscular epinephrine (e.g., EpiPen) into the vastus lateralis (mid-outer thigh).✓ 正解將一劑完整的肌肉注射腎上腺素（例如 EpiPen）注入股外側肌（大腿中段外側）。
- BElevate her legs vertically to push blood to her brain.垂直抬高雙腿，將血液推回大腦。
- CApply a thick layer of antibiotic-steroid cream on the bee sting wound.在蜜蜂螫傷處塗抹厚層抗生素類固醇藥膏。
- DCrush three aspirin tablets and administer them while waiting for an ambulance.壓碎三顆阿斯匹靈錠劑，並在等待救護車時給予服用。
過敏性休克（anaphylaxis）是 IgE 介導的全身性過敏反應，組織胺大量釋放導致血管擴張、低血壓、支氣管痙攣、喉頭水腫。 選項 A 正確：肌肉注射腎上腺素（IM epinephrine）是過敏性休克唯一救命首選藥物。透過 α1 收縮血管恢復血壓、β2 擴張支氣管緩解氣道阻塞。注射部位首選 vastus lateralis（大腿中外側股外側肌）。 選項 D 錯誤：阿斯匹靈與過敏無關，且本身可致過敏。 選項 B 錯誤：抬腿無法逆轉血管擴張性休克。 選項 C 錯誤：傷口擦藥對全身性過敏無用。
Anaphylaxis is IgE-mediated systemic hypersensitivity—massive histamine release causes vasodilation, hypotension, bronchospasm, and laryngeal edema. B correct: IM epinephrine is the only first-line lifesaving drug. Alpha-1 vasoconstriction restores BP; beta-2 bronchodilation relieves airway obstruction. Vastus lateralis (mid-outer thigh) is the preferred injection site. A incorrect: Aspirin doesn't help and can cause allergy. C incorrect: Leg elevation can't reverse vasodilatory shock. D incorrect: Topical creams don't treat systemic anaphylaxis.
