Explanation · 中文詳解

呋塞米(Furosemide)是強效的環利尿劑(loop diuretic),作用於亨利氏環(Loop of Henle),會抑制鈉與氯的再吸收,同時伴隨大量鉀離子排出。長期使用易導致低血鉀(hypokalemia),增加心律不整的風險。因此,監測血清鉀離子濃度是給藥前的必要評估,若過低需通知醫師調整劑量或補充鉀離子。

Furosemide is a potent loop diuretic that acts on the loop of Henle, inhibiting reabsorption of sodium and chloride while promoting substantial potassium excretion. Long-term use can readily cause hypokalemia, increasing the risk of cardiac arrhythmias. Therefore, monitoring the serum potassium level is an essential pre-administration assessment; if the level is too low, the nurse should notify the provider to adjust the dose or to supplement potassium.

✦ 台美臨床差異

在美國臨床,護理師給藥前若發現鉀離子偏低(如 < 3.5 mEq/L),通常會主動核對醫囑是否有補鉀劑(K-Dur/KCl),並在給藥前向醫師確認。
