Furosemide 屬於環利尿劑，會促進鉀離子隨尿液排出。低血鉀會增加毛地黃中毒風險並引發心律不整，因此給藥前務必確認電解質數值。其他選項與此藥物代謝關聯性較低，臨床作業中監測電解質是預防嚴重心血管併發症的關鍵預防措施。
Furosemide is a loop diuretic that promotes potassium excretion in the urine. Hypokalemia increases the risk of digoxin toxicity and arrhythmias, so electrolyte values must be confirmed before administration. The other options have low relevance to this medication's metabolism. Monitoring electrolytes in clinical practice is a key preventive measure against serious cardiovascular complications.
✦ 台美臨床差異
台灣醫院電子醫囑系統多會設定電解質異常警示，美國則更依賴護理師主動檢視檢驗報告。
