How can you prevent edema or swelling in the lower extremities?

• A. Elevate legs as ordered, promote activity as tolerated, and monitor for signs of edema; avoid crossing legs or placing pillows under knees unless ordered
• B. Elevate upper body only
• C. Promote complete bed rest
• D. Use continuous leg wraps without orders

Answer: (A)

The key idea is to boost venous return from the legs to prevent fluid from pooling and causing swelling. Elevating the legs as ordered helps gravity move fluid away from the feet and ankles, reducing edema. Encouraging activity as tolerated uses the calf muscles as a pump to push blood back toward the heart, which also helps prevent fluid from collecting in the legs. Monitoring for signs of edema—such as increasing swelling, tight or shiny skin, or changes in leg circumference—allows for early intervention if swelling worsens. It’s important to avoid crossing the legs or placing pillows under the knees unless specifically ordered, because these habits can restrict blood flow and keep the veins compressed, making edema more likely.

Choosing only upper-body elevation misses the principal area affected, and promoting complete bed rest reduces movement that aids venous return. Using continuous leg wraps without orders risks constriction and circulation problems, and should only be done under a clinician’s direction.
