Discharge instructions for cast care: which is correct?

• A. Keep the arm hanging down to improve circulation
• B. Use a coat hanger to itch in the cast
• C. Use a hair dryer to help dry it after it has got wet
• D. Keep the hand at the level of the heart

Answer: (D)

Elevation matters after a fracture with a cast because gravity affects swelling and how blood circulates back from the hand. Keeping the hand at the level of the heart helps venous return and reduces swelling inside and around the cast, which lowers pressure and pain and supports healing. Hanging the arm down makes swelling worse and can delay recovery. Inserting objects into the cast to scratch or itch can injure the skin and damage the cast, and using a hair dryer to dry a cast can heat or warp the material and irritate the skin. So, placing the hand at heart level best promotes comfort and healing.
