Explanation · 中文詳解

普萘洛爾(Propranolol)是一種非選擇性乙型交感神經阻斷劑(Non-selective Beta-blocker),其主要藥理作用為降低心率與心肌收縮力。由於該藥會顯著抑制心臟傳導系統,導致心搏過緩(Bradycardia),因此在給藥前,護理師必須評估心尖脈(Apical pulse)以確保心率在安全範圍內。若心率低於特定閾值(通常為 60 bpm),必須暫停給藥並通知醫師,這是給藥安全性評估的標準步驟。

Propranolol is a non-selective beta-blocker that reduces heart rate and myocardial contractility, risking bradycardia. Before administration the nurse must assess the apical pulse for a full minute. If the heart rate is below the threshold (commonly <60 bpm), hold the dose and notify the provider.
