The nurse is caring for a client with atrial fibrillation who receives a prescription for warfarin. The international normalized ratio (INR) is 2.8. Which action should the nurse take?

A. An INR of 2.8 is within the therapeutic range for clients on warfarin, so obtaining another blood sample is not necessary. B. An INR of 2.8 indicates that the client is within the therapeutic range, so it is appropriate to give the next scheduled dose. However, monitoring for potential bleeding complications is a higher priority. C. Monitoring for signs of bleeding is crucial because, while an INR of 2.8 is within the therapeutic range, it is still important to watch for any bleeding complications as part of routine care. D. Notifying the healthcare provider is not immediately necessary unless there are signs of bleeding or other concerns, as an INR of 2.8 is typically within the acceptable range for therapeutic anticoagulation.
