一位正在接受化學治療的病人，哪項實驗室檢測結果最令人擔憂？
Which lab finding is most concerning for a client receiving chemotherapy?
- APlatelets 150,000/mm³血小板 150,000/mm³
- BHemoglobin 11 g/dL血紅素 11 g/dL
- CWBC 1,500/mm³✓ 正解白血球 1,500/mm³
- DCreatinine 1.0 mg/dL肌酸酐 1.0 mg/dL
— Explanation · 中文詳解 —
化療病人最嚴重的併發症之一是骨髓抑制，WBC 1,500/mm³ 代表嚴重的嗜中性白血球低下，病人極易發生致命性的院內感染。Hb 11 g/dL 雖貧血但尚可接受，血小板 150k 屬正常範圍，Cr 1.0 亦在正常內。
Chemotherapy commonly causes bone marrow suppression, leading to severe neutropenia when the white blood cell count drops to 1,500/mm³. This condition significantly increases the risk of life-threatening infections, making it the most critical finding among the options. Other values such as hemoglobin, platelets, and creatinine are either within normal limits or represent less acute concerns.
✦ 台美臨床差異
美台皆將 Neutropenic Precautions 納入化療護理的核心，以應對 WBC 低下的風險。
