The patient's PT and INR levels are significantly elevated, indicating that the patient is at high risk for bleeding. Therefore, the nurse should hold the dose of warfarin and notify the healthcare provider immediately for further instructions. Administering or increasing the dose of warfarin could lead to excessive bleeding and harm the patient. Giving one-half the dose may not be appropriate, given the patient's high INR level. Prompt communication with the healthcare provider is essential to ensure safe and effective medication management.
