抗心律不整藥物（Amiodarone）靜脈輸注時，若出現低血壓及心搏徐緩，代表藥物已對心肌傳導系統產生過度抑制作用或造成周邊血管擴張。在NCLEX臨床情境中，當藥物引發血流動力學不穩定（Hemodynamic instability）時，首要動作永遠是「停止給藥」以阻斷病因。後續再執行評估（Assess）與醫師通知（Notify），這符合護理優先順序中的安全原則。
When a client develops hypotension and bradycardia during an amiodarone infusion, the priority action is to stop the infusion immediately to prevent further hemodynamic instability. After stopping the medication, the nurse should notify the healthcare provider to determine the next steps for management.
