A 68-year-old male on warfarin for atrial fibrillation presents for routine INR check, which is 6.5. He denies any bleeding. His target INR is 2.0-3.0. What is the most appropriate management?

✓ Correct Answer: Option B

For an asymptomatic patient on warfarin with an INR between 4.5 and 10.0, the recommended management is to hold the warfarin dose and recheck the INR within 24 hours. Vitamin K is typically reserved for INR >10 or bleeding.
