What is primary prevention of DVT in hospitalized patients?

• A. Early ambulation and SCDs
• B. Adequate hydration
• C. Routine bed rest
• D. Frequent blood draws

Answer: (A)

Preventing DVT before it happens relies on improving venous return and reducing blood stasis in the legs. Getting patients moving as soon as it’s safe, along with using devices that mechanically compress the legs (sequential compression devices), directly tackles the main problem that allows clots to form in hospitalized people. Early ambulation strengthens the calf muscle pump, which propels blood back toward the heart, while SCDs continuously promote flow and reduce pooling in the veins. Hydration helps overall health but isn’t a reliable standalone method to prevent DVT in the hospital. Routine bed rest worsens venous stasis, and frequent blood draws don’t prevent DVT and can contribute to venous issues. So the combination of early movement and mechanical prophylaxis best prevents DVT in this setting.
