After casting, limb position in first 48 hours?

• A. Resting flat on bed
• B. Hanging over edge of bed
• C. Elevated below heart
• D. Elevated above heart for the first 48 hours

Answer: (D)

Elevating the injured limb above heart level in the first 48 hours helps reduce swelling by using gravity to improve venous and lymphatic return. Lower tissue pressure decreases pain and lowers the risk of increased pressure inside the cast, which can compromise nerves and blood flow. Resting flat or letting the limb hang over the edge can worsen edema, and elevating below heart level is less effective at reducing swelling. Keeping the limb raised above the heart during the initial 2 days is the best approach for helpful circulation and comfort, then gradually lowering as swelling declines.
