Which non-pharmacologic measure helps prevent DVT?

• A. Compression stockings
• B. Massage therapy
• C. Prolonged bed rest
• D. High-sodium diet

Answer: (A)

Preventing DVT relies on keeping blood moving in the leg veins to avoid venous stasis. Graduated compression stockings achieve this by applying the tightest pressure at the ankle and gradually less up the leg, which helps squeeze blood back toward the heart and reduces pooling in the deep veins. This mechanical aid is a standard nonpharmacologic measure to prevent DVT, especially after surgery or during periods of limited mobility.

Massage therapy isn’t a primary preventive strategy and can be risky if a clot is already present. Prolonged bed rest actually increases DVT risk by promoting stasis. A high-sodium diet does not prevent DVT and can worsen edema. Ensure proper fit and skin care when using compression stockings, and consult if there are arterial insufficiency concerns.
