病人獲醫囑給予 Furosemide 40 mg IV push。護理師在給藥過程中應優先確認哪項臨床發現，以預防併發症？
A client is prescribed furosemide 40 mg IV push. Which clinical finding should the nurse prioritize to prevent a complication during administration?
- ASerum creatinine of 1.1 mg/dL血清肌酸酐 1.1 mg/dL
- BPotassium level of 3.2 mEq/L✓ 正解鉀離子濃度 3.2 mEq/L
- CUrine output of 50 mL/hr尿量 50 mL/hr
- DBlood pressure of 110/70 mmHg血壓 110/70 mmHg

Furosemide 為強效環利尿劑，會導致鉀離子經由尿液大量流失。在給藥前若發現低血鉀（<3.5 mEq/L），應先通知醫師，以免引發嚴重心律不整或毛地黃中毒風險。其他選項對於單次給藥而言非即刻禁忌。
Furosemide is a potent loop diuretic that causes substantial urinary loss of potassium. Before administration, if hypokalemia (<3.5 mEq/L) is detected, the physician should be notified first to avoid the risk of serious dysrhythmias or digoxin toxicity. The other options are not immediate contraindications for a single dose.
✦ 台美臨床差異
美國護理師常依據實驗室數據自行判斷給藥；台灣基層護理常需確認醫師確認給藥依據，兩地均重視電解質監測。
