Explanation · 中文詳解

普萘洛爾(Propranolol)是一種非選擇性乙型受體阻斷劑(non-selective beta-blocker),它會阻斷心臟上的乙型-1(beta-1)受體和肺部支氣管上的乙型-2(beta-2)受體。在心臟,阻斷乙型-1 受體可以降低心率和心臟收縮力,從而降低血壓,這對高血壓病人是有益的。 然而,對於有氣喘病史的病人而言,阻斷肺部的乙型-2 受體會導致支氣管收縮(bronchoconstriction),這會使氣道狹窄,加劇氣喘症狀,可能引發嚴重的呼吸困難甚至氣喘發作。因此,普萘洛爾對氣喘病人是禁忌使用的。護理師在發現此醫囑時,應立即質疑醫囑的合理性,並與醫師溝通,以確保病人用藥安全,避免潛在的嚴重呼吸道併發症。

Propranolol is a non-selective beta-blocker that can cause bronchoconstriction by blocking beta-2 receptors in the lungs, posing a severe risk to clients with asthma. The nurse must question this order to prevent potentially fatal respiratory complications.
