- BSerum glucose血清葡萄糖
- CSerum potassium✓ 正解血清鉀

— Explanation · 中文詳解 —
Furosemide 是排鉀利尿劑，會導致鉀離子經腎臟大量排出。給藥前若病人的血鉀數值過低，會增加引發心律不整的風險。因此，監測血鉀濃度是確保病人用藥安全的核心，若數值異常則應先徵詢醫師是否暫停用藥或補鉀。
Furosemide is a potassium-wasting loop diuretic that causes substantial renal potassium excretion. If serum potassium is already low before administration, the risk of arrhythmias increases. Therefore, monitoring serum potassium is core to safe administration; if abnormal, consult the physician about holding the dose or supplementing potassium.
