A nurse is reinforcing teaching with a parent of a child who has a sprained wrist. Which of the following interventions should the nurse instruct the parent to implement during the first 12 to 24 hr to minimize swelling?

A. Encouraging active range of motion of the extremity can increase swelling and is not recommended immediately after a sprain. B. Elevating the extremity above the level of the heart helps reduce swelling by promoting venous return. C. Wrapping the extremity loosely with an elastic bandage provides some support but is not the most effective way to reduce swelling. D. Applying warm compresses can increase blood flow and swelling; cold compresses are recommended during the first 24 hours.
