護理師照顧一位患有慢性腎臟病（CKD）的病人，醫囑開立 epoetin alfa。護理師應檢視哪項實驗室數值以評估該藥物的治療效果？
A client with chronic kidney disease (CKD) is prescribed epoetin alfa. Which laboratory value should the nurse review to evaluate the therapeutic effectiveness of this medication?
- AHemoglobin level✓ 正解血红素浓度
- BBlood urea nitrogen尿素氮
- CSerum creatinine血清肌酸酐
- DPotassium level钾离子浓度
Epoetin alfa 為人工合成紅血球生成素，用於治療因慢性腎臟病（CKD）導致的腎性貧血。評估其療效的核心指標在於檢測「血紅素（Hemoglobin）水平」的上升情況。透過定期監測血紅素，能評估紅血球生成是否達到改善貧血的目標。肌酸酐與 BUN 評估腎功能，鉀離子評估電解質，均非評估此藥物療效的指標。
Epoetin alfa is a synthetic erythropoietin used to treat renal anemia caused by chronic kidney disease (CKD). The core indicator for evaluating its therapeutic effect is the rise in hemoglobin level. Periodic monitoring of hemoglobin allows the nurse to assess whether erythropoiesis has improved the anemia. Creatinine and BUN reflect renal function, and potassium reflects electrolyte balance; none of these directly evaluate the efficacy of this drug.
