The target INR range can vary depending on the condition being treated. For most patients on warfarin for conditions such as atrial fibrillation or venous thromboembolism, the typical target range is between 2.0 and 3.0. However, patients with mechanical heart valves may require a higher range, such as 2.5 to 3.5. It is essential for nurses to know the specific target range for each patient and to understand that individual needs may vary.
