一位腫瘤科護理師被分配照顧四名因化療而經歷各種併發症的病患。在完成初步巡房後，護理師必須優先評估與處置哪一位病患，以避免潛在的快速致命結果？
An oncology nurse is assigned to care for four clients experiencing various complications from chemotherapy. Upon completing initial rounds, which client must the nurse evaluate and manage first to prevent a potentially rapid fatal outcome?
- AA profoundly nauseous client who just forcefully vomited 300 mL of dark green bile completely unexpectedly across the bathroom.嚴重噁心且突然用力嘔吐 300 mL 深綠色膽汁的病患
- BA client with a documented neutrophil count of 300/mm³ and a developing mild cough registering a temperature of 38.3°C (101°F).✓ 正解記錄嗜中性白血球計數為 300/mm³ 且出現輕微咳嗽、體溫達 38.3°C (101°F) 的病患
- CA client displaying scattered distinct tiny red petechiae on their lower calves effectively.小腿下部散佈明顯微小紅斑（瘀點）的病患
- DA client reporting excruciating 9/10 burning pain directly associated with severe oral mucositis refusing to eat or swallow liquids entirely.主訴嚴重口腔黏膜炎導致劇烈灼痛（9/10），完全拒絕進食或飲水的病患
本題測驗腫瘤科病房檢傷優先排序 (Establishing Priorities)。對於化療病患，免疫遭到摧毀造成的『嗜中性白血球低下 (Neutropenia)』最大的死神。正常絕對嗜中性白血球計數 (ANC) 應大於 1500。選項 B 的病患 ANC 僅有 300，且出現了全新發作的微溫 38.3°C 以及咳嗽。對於 ANC 極低的化療患者，任何大於 38°C 的微燒皆代表『嗜中性白血球低下發燒 (Febrile Neutropenia)』，這是一場高死亡率的急症！如果不立刻在一小時內啟動血液培養並施打抗生素，病患將在一兩小時內陷入敗血性休克死亡。因此選項 B 是絕對第一優先的紅色重症。選項 D 口腔黏膜炎雖痛，但在不危及呼吸的情況下屬症狀控制。選項 A 化療嘔吐雖然極度不適但為預期內反應。選項 C 出現點狀出血代表血小板低下，尚未達到如敗血症般秒殺的程度。
Febrile neutropenia is a life-threatening oncologic emergency that requires immediate evaluation and treatment to prevent septic shock. A client with a neutrophil count of 300/mm³ and a temperature above 38°C needs urgent blood cultures and antibiotics. Other symptoms like nausea, petechiae, or mucositis pain, while significant, do not pose the same immediate risk of rapid fatality.
世界腫瘤病房最高紅線：「白血球低下 (Neutropenia) + 發燒」 = 敗血症警報，直接衝第一優先。
