Which DVT prevention method is described in the material?

• A. Early ambulation and SCDs
• B. Bed rest and no movement
• C. Severe caloric restriction
• D. Frequent venipuncture

Answer: (A)

Promoting venous return to prevent DVT is the main idea. Moving soon after a procedure or time of reduced activity activates the calf muscles, which squeeze the deep veins and push blood back toward the heart. That calf-pump action reduces venous stasis, a key factor in clot formation. When movement isn’t possible, devices that provide sequential leg compression mimic that pumping effect by inflating and deflating to encourage blood flow, further lowering the risk of a clot.

The other options don’t address this essential mechanism. Bed rest and no movement worsen venous stasis, increasing DVT risk. Severe caloric restriction isn’t a DVT prevention method and can harm overall health. Frequent venipuncture isn’t about preventing clots; it can irritate or damage veins and isn’t protective against DVT.

So combining early ambulation with compression devices best aligns with reducing venous stasis and preventing DVT.
