一位正在接受化學治療的病人。哪項實驗室數值是感染風險中最需擔心的？
A nurse is caring for a client receiving chemotherapy. Which laboratory value is the greatest concern for infection?
- ARed blood cell count紅血球計數
- BHemoglobin level血紅素濃度
- CPlatelet count血小板計數
- DAbsolute Neutrophil Count (ANC)✓ 正解絕對中性白血球計數 (ANC)
— Explanation · 中文詳解 —
化療病人最嚴重的風險之一是嗜中性白血球低下（Neutropenia）。ANC（絕對嗜中性白血球計數）直接反映身體對抗細菌感染的能力。當 ANC 過低，病人極易發生嚴重感染，需執行保護性隔離措施。其他項目與凝血或貧血有關，雖重要但不直接代表感染風險。
The Absolute Neutrophil Count (ANC) is the most critical indicator of a chemotherapy patient's ability to fight infection, as neutropenia significantly increases the risk of severe sepsis. Unlike red blood cell counts, hemoglobin, or platelet levels, which relate to oxygen transport or clotting, the ANC directly reflects immune competence against bacterial threats.
✦ 台美臨床差異
在腫瘤病房的照護中，美台兩地均嚴格監測 ANC，並依此數值啟動隔離防護與給予升白球素。
