Furosemide 是排鉀利尿劑，長期使用容易造成低血鉀，正常值為 3.5-5.0 mEq/L。2.8 mEq/L 屬於嚴重低血鉀，會引起心律不整甚至致命。其他選項皆為藥物治療後的預期性結果或正常範圍。
Furosemide is a potassium-wasting diuretic, and long-term use can cause hypokalemia; the normal range is 3.5-5.0 mEq/L. A value of 2.8 mEq/L represents severe hypokalemia, which may cause life-threatening arrhythmias. The other options are expected outcomes of therapy or fall within normal ranges.
