護理師照顧一位有蜂螫過敏史的病人，應確保床邊備有何種物品？
A nurse is caring for a client with a known history of anaphylaxis to bee stings. Which item should the nurse ensure is readily available at the bedside?
- AEpinephrine auto-injector✓ 正解腎上腺素自動注射器
- BSterile gauze pads無菌紗布墊
- COxygen tank with a non-rebreather mask配備非再吸入式面罩的氧氣瓶
- DOral antihistamine口服抗組織胺
過敏性休克（Anaphylaxis）是一種全身性、快速發作且危及生命的過敏反應，常見表現包括呼吸道水腫、支氣管收縮及嚴重低血壓。腎上腺素（Epinephrine）是治療過敏性休克的首選藥物，具有收縮血管、擴張支氣管及抑制組織胺釋放的作用。對於有過敏史的病人，床邊備有自動注射器（Auto-injector）能確保在症狀出現時立即給藥，搶救黃金時間。
Anaphylaxis is a systemic, rapidly developing, life-threatening allergic reaction commonly presenting with airway edema, bronchoconstriction, and severe hypotension. Epinephrine is the first-line treatment for anaphylaxis; it causes vasoconstriction, bronchodilation, and suppression of histamine release. For clients with a history of allergy, having an auto-injector available at the bedside ensures that medication can be administered immediately when symptoms occur, preserving the critical window for rescue.
