What action should the nurse take for a client with deep-vein thrombosis (DVT)?

Elevating the affected limb in a client with deep-vein thrombosis (DVT) is an essential nursing intervention. This action helps to reduce swelling and promote venous return, which can alleviate discomfort and support recovery. Elevation of the limb encourages blood flow back toward the heart and can minimize pooling of blood in the veins, potentially decreasing the risk of further complications related to DVT.

While other options may seem beneficial, they can pose risks in the context of DVT management. For instance, massaging the affected limb can dislodge a clot, leading to severe complications such as a pulmonary embolism. Encouraging immediate walking may also be contraindicated, especially if the client is at significant risk of clot complications. Similarly, applying heat can exacerbate inflammation and may also encourage clot dislodgment. Thus, elevation is the safest and most appropriate action to take in managing a client with DVT.
