학습 자료 둘러보기 →A patient on warfarin for atrial fibrillation has an INR of 6.8. This is a critically supratherapeutic level, far exceeding the standard target of 2.0 to 3.0, and poses an imminent risk of major hemorrhage.
Immediate intervention requires holding the next warfarin dose and assessing for any signs of active bleeding. The provider must be notified urgently to consider administering oral vitamin K for reversal, especially if bleeding is present or the risk is high.
Do not confuse an INR of 3.2 with a critical value. While it requires a dose adjustment, it does not typically necessitate emergency reversal with vitamin K unless bleeding occurs. Over-correction can lead to thrombosis.
