— Explanation · 中文詳解 —
Furosemide 為環利尿劑（loop diuretic），會導致尿液中鉀離子大量流失。低血鉀（hypokalemia）對服用毛地黃等強心劑的病人極度危險，可能誘發嚴重心律不整，因此鉀離子是此類藥物監測的首要項目。
Furosemide is a loop diuretic that causes substantial urinary potassium loss. Hypokalemia is extremely dangerous in clients taking inotropic agents such as digoxin and can precipitate serious dysrhythmias, making serum potassium the primary monitoring parameter for this class of medication.
✦ 台美臨床差異
美國護理師常依據檢驗報告主動建議醫師補充鉀離子（依據 protocol），台灣則需取得醫師確認後給藥。
