護理師在急診檢傷分類區，哪一位病人應優先安排就診？
A nurse is working in the triage area of an emergency department. Which client should be seen first?
- AA client reporting chest pain radiating to the jaw✓ 正解主訴胸痛放射至下顎的病人
- BA client with a small, clean laceration患有小型清潔撕裂傷的病人
- CA client with a closed wrist fracture患有閉合性手腕骨折的病人
- DA client with a mild headache for two days輕微頭痛已持續兩天的病人
急診檢傷分類（Triage）遵循 ABC 原則（Airway, Breathing, Circulation），優先處理危及生命或器官功能的狀況。胸痛伴隨放射至下顎的疼痛，是急性冠狀動脈症候群（ACS）的警訊，極可能進展為心肌梗塞，需立即評估心電圖及給予緊急藥物以保全心肌。其餘選項雖有不適，但皆屬於相對穩定或非立即危及生命的病況。
Emergency department triage follows the ABC principle (Airway, Breathing, Circulation), prioritizing conditions that threaten life or organ function. Chest pain radiating to the jaw is a red-flag symptom for acute coronary syndrome (ACS) that may progress to myocardial infarction and requires immediate ECG evaluation and emergency medications to preserve myocardium. The other options, although uncomfortable, are relatively stable or not immediately life-threatening.
美國急診檢傷常用 ESI (Emergency Severity Index) 分級系統，胸痛通常被直接判定為 ESI 2 級（需立即評估），而台灣部分醫院亦採用類似分級，但實務上美國對胸痛的處理流程（如 door-to-ECG time）更為嚴格。
