病人獲醫囑給予靜脈推注呋塞米（Furosemide）40 mg。給藥前護理師發現血鉀濃度為 3.1 mEq/L。優先處理措施為何？
A client is prescribed furosemide 40 mg IV push. Before administration, the nurse notes a serum potassium level of 3.1 mEq/L. What is the priority nursing action?
- AHold the dose and notify the physician✓ 正解暫停用藥並通知醫師
- BAdminister potassium supplement with the dose給藥時同時給予鉀離子補充劑
- CAdminister the furosemide and notify the physician給予呋塞米並通知醫師
- DDocument the laboratory results in the chart將檢驗結果記錄於病歷中
呋塞米屬於排鉀利尿劑，會進一步降低血鉀。正常血鉀範圍為 3.5-5.0 mEq/L，目前病人已處於低血鉀狀態，若強行給藥可能引發嚴重的心律不整（如室性心律不整或毛地黃中毒）。依據安全給藥原則，護理師應先暫停給藥，並立即通知醫師進行評估與處置，避免病人情況惡化。
Furosemide is a potassium-wasting diuretic and will further lower serum potassium. The normal range for serum potassium is 3.5-5.0 mEq/L, and this client is already hypokalemic; administering the drug as ordered could precipitate serious dysrhythmias (such as ventricular arrhythmias or digoxin toxicity). Following safe medication-administration principles, the nurse should hold the dose and promptly notify the physician for evaluation and intervention to prevent further deterioration.
美台臨床對於給藥前的檢驗值監測觀念一致，護理師均有權利且義務暫停給藥並回報以防醫療錯誤。
