— Explanation · 中文詳解 —
Amiodarone 是一種強效抗心律不整藥物，常見副作用包括心搏徐緩（Bradycardia）與低血壓。當病人出現心搏徐緩時，代表藥物已產生過度的電生理抑制，若繼續輸注可能導致心跳停止或嚴重心輸出量下降。此時遵循 NCLEX 的安全護理原則：當藥物引起嚴重不良反應時，優先處置為「停止輸注」，隨後再依據醫師醫囑或 ACLS 流程進行後續處理。
Amiodarone can cause significant bradycardia due to its electrophysiological effects. When this adverse reaction occurs, the priority nursing action is to stop the infusion immediately to prevent further cardiac suppression and then notify the healthcare provider.
