由於社區發生嚴重災難，極度缺乏人手的內外科病房必須緊急讓病患出院，以挪出創傷病床。根據檢傷與管理原則，哪位住院中的病患展現出最安全的特徵，適合立即安排快速出院？
Due to a severe community disaster, a heavily understaffed medical-surgical unit must urgently discharge clients to create available trauma beds. According to triage and management principles, which active client demonstrates the safest profile for immediate rapid discharge?
- AA client admitted exactly 12 hours ago with severe unstable angina scheduled for a coronary angiogram procedure closely eagerly tomorrow morning.入院剛好12小時，患有嚴重不穩定型心絞痛，明天一早緊迫期待安排冠狀動脈血管攝影術的病人。
- BA client accurately presenting with chronic exacerbation of heart failure still heavily requiring continuous intravenous furosemide diuretic therapy.準確呈現慢性心臟衰竭惡化，仍重度依賴持續靜脈注射利尿劑（furosemide）治療的病人。
- CA client displaying an active new profound deep vein thrombosis currently requiring stringent continuous intravenous heparin therapy safely securely.顯示活動性新發嚴重深部靜脈血栓形成，目前需要嚴格持續靜脈注射肝素（heparin）治療的病人。
- DA client 2 days post-op from a total knee arthroplasty who is successfully taking oral pain medications and aggressively engaging in physical therapy.✓ 正解全膝關節置換術後2天，成功服用口服止痛藥並積極參與物理治療的病人。
本題測驗災害護理的病床清空決策 (Disaster Triage/Bed Management)。當醫院發生大規模災難 (MCI) 需要清出床位時，被拔除床位的病患必須符合「慢性、生理跡象穩定、能由家屬照顧或只需口服藥」的條件。選項 D 是人工膝關節置換術後第 2 天的病患，目前已經改用『口服止痛藥 (oral pain medications)』並且能進行物理治療，這代表他已經完全脫離了危險的麻醉監控與 IV 止痛依賴，可以拿著口服藥回家靜養（選 D 最安全）。選項 B (打靜脈利尿劑)、選項 A (心絞痛等待心導管手術)、選項 C (急性 DVT 滴注肝素)，這三個全都是必須留在醫院施打高危險靜脈點滴或面臨隨時心臟猝死風險的高危險病人。
In disaster situations requiring rapid bed turnover, the safest candidates for discharge are those who are stable, independent, and no longer require acute interventions such as IV medications or continuous monitoring. A client two days post-knee arthroplasty who is tolerating oral medications and participating in physical therapy meets these criteria, unlike those with unstable angina, active heart failure, or acute DVT.
災難床位管理核心：把「IV medication (靜脈給藥)」的病人留下，把「PO medication (口服給藥)」的病人送回家。全世界皆然。
