The nurse notes in the patient’s medication orders that the patient will be starting anticoagulant therapy. What is the primary goal of anticoagulant therapy?

Choice A reason: Stabilizing an existing thrombus is not the primary goal of anticoagulant therapy, which focuses on preventing new clot formation. Thrombolytics dissolve clots, while anticoagulants inhibit clotting factors, making this incorrect, as prevention, not stabilization, is the main therapeutic objective. Choice B reason: Dilating vessels is not an effect of anticoagulants, which inhibit clotting factors to prevent thrombus formation. Vasodilation is achieved by other drugs like nitrates, making this incorrect, as it does not align with the mechanism or goal of anticoagulant therapy. Choice C reason: The primary goal of anticoagulant therapy is to prevent thrombus formation by inhibiting clotting factors, reducing the risk of thromboembolism in conditions like atrial fibrillation or DVT. This aligns with the therapeutic purpose, making it the correct goal for the nurse to understand. Choice D reason: Dissolving existing thrombi is the role of thrombolytic therapy, not anticoagulants, which prevent new clots. Anticoagulants like heparin maintain clot stability but do not lyse clots, making this incorrect, as prevention is the primary focus of anticoagulant therapy.
