Which intervention helps prevent deep vein thrombosis in at-risk patients?

• A. Use intermittent compression devices
• B. Massage the legs
• C. Prolonged bed rest
• D. High-sodium diet

Answer: (A)

Preventing deep vein thrombosis relies on reducing venous stasis in the legs. Intermittent pneumatic compression devices do this by periodically inflating and deflating around the calves and thighs, which mimics the natural muscle pump that occurs with movement. This action increases venous blood flow, discourages pooling in the deep veins, and lowers the likelihood that clots will form in immobilized or high-risk patients. Leg massage might seem helpful, but it can dislodge a clot or push it toward the lungs, so it isn’t a recommended preventive measure in at-risk individuals. Prolonged bed rest actually raises DVT risk by keeping the veins stagnant. A high-sodium diet doesn’t prevent DVT and isn’t related to clot formation.
