For a patient with DVT, which intervention is appropriate?

Administering anticoagulants as prescribed is the most appropriate intervention for a patient with deep vein thrombosis (DVT). Anticoagulant medication helps to prevent the formation of new clots and reduces the risk of the existing clot becoming larger. It is essential in managing DVT because it directly targets the underlying problem by affecting the blood's ability to clot, thus promoting better blood flow and lowering the risk of complications, such as pulmonary embolism.

In contrast, immobilizing the affected limb may lead to further complications and does not address the risk of clot extension or new clot formation. Encouraging hot baths may not be advisable as heat can cause blood vessels to dilate, potentially increasing the risk of thrombus formation. Restricting fluid intake is not beneficial either; proper hydration is important for overall vascular health and can actually help prevent complications. Therefore, administering anticoagulants is the best choice in managing DVT effectively.
