مريض يأخذ وارفارين، INR اليوم ٥٫٨، ولا يوجد نزيف. ما المتوقع غالباً؟

A client on warfarin has an INR of 5.8 today with no bleeding. What is usually expected?

1. No adjustment is needed
2. Double today’s dose
3. Withhold doses; oral vitamin K
4. Immediate platelet transfusion

Answer: C) Withhold doses; oral vitamin K. A high INR without bleeding is managed by withholding doses and sometimes oral vitamin K; major bleeding needs IV vitamin K and prothrombin complex.
