— Explanation · 中文詳解 —
Furosemide 是排鉀利尿劑，低血鉀（<3.5 mEq/L）是其常見且嚴重的副作用，可能導致致命性心律不整。2.8 mEq/L 屬於嚴重低鉀。鈉（138）、鈣（9.0）與血糖（110）均在正常或接近正常範圍，不具立即危險性。
Furosemide is a potassium-wasting diuretic; hypokalemia (<3.5 mEq/L) is a common and serious adverse effect that may lead to fatal arrhythmias. A potassium level of 2.8 mEq/L represents severe hypokalemia. Sodium (138), calcium (9.0), and blood glucose (110) are all within or near the normal range and do not pose an immediate danger.
✦ 台美臨床差異
美國護理師常依據 Protocol 自行啟動補鉀程序；台灣通常需先通報值班醫師開立處方後執行。
