醫師醫囑為急性肺水腫病人給予靜脈推注利尿劑 Furosemide 40 mg。給藥後，護理師評估哪項指標最為關鍵？
A client is prescribed furosemide 40 mg IV push for pulmonary edema. Which assessment finding is most important for the nurse to evaluate following administration?
- ASerum creatinine血清肌酸酐
- BBlood pressure✓ 正解血壓
- CUrine output尿液排出量
- DPotassium level鉀離子濃度
Furosemide 是強效袢利尿劑，經靜脈推注後作用極快，主要機制為降低血管內容量。急性肺水腫病人常伴隨血流動力學不穩定，快速降壓可能引發低血壓休克，因此給藥後立即監測血壓是確保循環穩定的核心。血鉀與肌酸酐雖然重要，但多屬於給藥前參考或給藥後長期監測項目，而非急性給藥後的立即優先指標。
Furosemide is a potent loop diuretic. After IV push, its onset is very rapid, with the main mechanism being a reduction in intravascular volume. Clients with acute pulmonary edema often have unstable hemodynamics, and rapid lowering of blood pressure may precipitate hypotensive shock. Therefore, monitoring blood pressure immediately after administration is the core measure to ensure circulatory stability. Although serum potassium and creatinine are important, they usually serve as pre-administration references or long-term post-administration monitoring parameters, rather than the immediate priorities after an acute dose.
美國護理師常依護理評估直接執行給藥，台灣臨床則更嚴謹執行給藥後護理紀錄與生命徵象追蹤。
