護理師照護一位服用 furosemide (Lasix) 的心臟衰竭病人，下列何項評估發現最應報告給醫療提供者？
A nurse is caring for a client with heart failure who is prescribed furosemide (Lasix). Which assessment finding is most important to report to the healthcare provider?
- AClient's weight has decreased by 3 lbs since yesterday病人體重較昨日減輕 3 磅
- BClient has audible crackles at the lung bases病人肺底部可聽聞捻发音
- CClient's potassium level is 3.2 mEq/L✓ 正解病人血鉀濃度為 3.2 mEq/L
- DClient reports mild dizziness when standing病人報告站立時有輕微頭暈
Furosemide 是利尿劑，常見副作用為低血鉀（Hypokalemia）。血鉀 3.2 mEq/L 低於正常範圍（3.5-5.0 mEq/L），可能引起心律不整等嚴重併發症，需立即報告並可能調整藥物。其他選項為利尿劑效果（A）或心衰竭症狀（D, B）的觀察點，但不如低血鉀嚴重。
Furosemide is a loop diuretic, and hypokalemia is a common adverse effect. A potassium level of 3.2 mEq/L is below the normal range (3.5–5.0 mEq/L) and may precipitate serious arrhythmias; this requires immediate reporting and possible dose adjustment. The other findings reflect expected diuretic effects (A) or heart-failure manifestations (D, B) that are less critical than hypokalemia.
美國護理師在給予利尿劑後，會主動監測電解質變化，並依據檢驗結果提出藥物調整建議；台灣則可能在檢驗結果出來後，主要由醫師診斷並開立醫囑。
