Furosemide 是高效能利尿劑，會導致鉀離子經由尿液大量流失。當血鉀數值低於正常範圍（3.5-5.0 mEq/L）時，給予利尿劑恐引發致命性心律不整，護理師應暫緩給藥並回報檢驗值，以便醫師評估補鉀需求。
Furosemide is a potent diuretic that causes substantial loss of potassium through the urine. When the serum potassium level is below the normal range (3.5-5.0 mEq/L), administering the diuretic may precipitate life-threatening cardiac dysrhythmias. The nurse should hold the dose and report the lab value so the provider can evaluate the need for potassium replacement.
✦ 台美臨床差異
台灣臨床常規給予利尿劑時，若血鉀偏低，護理師多會與藥師或醫師確認是否給予口服鉀離子補充，流程較為緊密。
