一位有氣喘病史的病人被開立 propranolol。護理師最重要的執行措施為何？
A client with a history of asthma is prescribed propranolol. Which intervention is most important for the nurse to perform?
- ACheck for peripheral edema檢查周邊水腫
- BMonitor blood glucose levels regularly定期監測血糖
- CMonitor for symptoms of bradycardia監測心搏過緩症狀
- DAssess breath sounds for wheezing✓ 正解評估呼吸音是否有喘鳴
— Explanation · 中文詳解 —
Propranolol 為非選擇性 beta 受體阻斷劑，會阻斷支氣管上的 beta-2 受體，進而導致支氣管收縮，誘發氣喘發作。因此，對於氣喘病人，監測呼吸道通暢性與肺部呼吸音是預防嚴重併發症的首要護理重點。
Propranolol is a nonselective beta blocker that blocks beta-2 receptors in the bronchi, causing bronchoconstriction and potentially triggering an asthma attack. Therefore, in asthmatic patients, monitoring airway patency and breath sounds is the primary nursing priority for preventing serious complications.
✦ 台美臨床差異
美國常規使用選擇性 beta-1 阻斷劑（如 metoprolol）取代 propranolol；台灣臨床上 propranolol 多用於甲狀腺亢進或偏頭痛治療，呼吸照護意識需更強。
