病人因液體過載被開立 40 mg 靜脈注射速尿靈（Furosemide）。護理師評估發現血鉀濃度為 2.8 mEq/L。優先採取哪項行動？
A client is prescribed intravenous furosemide 40 mg for fluid overload. The nurse assesses the client and notes a potassium level of 2.8 mEq/L. Which action is the priority?
- AAdminister an oral potassium supplement給予口服鉀離子補充劑
- BAdminister the furosemide as ordered依醫囑給予速尿靈
- CHold the dose and notify the physician✓ 正解暫停給藥並通知醫師
- DIncrease dietary potassium intake增加飲食中的鉀攝取量
Furosemide 為環利尿劑，會導致鉀離子經由尿液大量流失。病人目前的血鉀值嚴重偏低（正常範圍 3.5-5.0 mEq/L），若直接給藥可能誘發致死性心律不整。護理師應先扣住藥物並聯繫醫師，評估補鉀需求，而非單純調整飲食或自行加藥。
Furosemide is a loop diuretic that causes substantial urinary potassium loss. The client's potassium level is significantly below the normal range (3.5-5.0 mEq/L); administering the drug under these conditions could precipitate fatal dysrhythmias. The nurse should hold the dose and notify the physician to evaluate the need for potassium replacement, rather than simply adjusting the diet or independently administering supplemental potassium.
美台臨床對於嚴重電解質異常皆遵循扣藥（Hold medication）準則，但美國護理師依據 Standing Order 可能更靈活執行補鉀。
