— Explanation · 中文詳解 —
Furosemide 屬於環利尿劑（Loop diuretic），作用於亨利氏環阻斷鈉與氯的再吸收，同時會增加鉀離子的排泄。臨床上最常見且嚴重的副作用為低血鉀，容易誘發心律不整，因此給藥前後監測血鉀濃度極為關鍵。
Furosemide is a loop diuretic that acts on the loop of Henle to block the reabsorption of sodium and chloride while also increasing the excretion of potassium. Clinically, the most common and serious adverse effect is hypokalemia, which can easily precipitate dysrhythmias; therefore, monitoring serum potassium levels before and after administration is critical.

無明顯差異，皆將監測血鉀作為使用環利尿劑的標準護理常規。
