What should a nurse monitor for in a patient receiving anticoagulant therapy due to atrial fibrillation?

Monitoring for signs of bleeding is crucial for a patient receiving anticoagulant therapy due to atrial fibrillation. Anticoagulants are designed to prevent the formation of blood clots, but they also increase the risk of bleeding complications. Therefore, the nurse should be vigilant for any indicators of hemorrhage, such as unusual bruising, blood in urine or stool, prolonged bleeding from cuts, or any significant changes in vital signs that suggest internal bleeding.

Effective management of anticoagulant therapy includes routine assessment for these signs, as early detection can prevent serious outcomes. This approach is particularly pertinent in patients with atrial fibrillation, as they are often at a higher risk for stroke and other thromboembolic events, necessitating careful monitoring not only of therapeutic effects but also of potential adverse effects associated with anticoagulant use.
