A nurse is providing care for an infant with new casts for the treatment of club foot. Which intervention is appropriate in promoting the infant's comfort and preventing complications?

A. Elevating the legs on a pillow helps reduce swelling and discomfort while the cast is healing. B. Heat therapy should not be applied to the casted area, as it could cause skin irritation or burns. C. Casts should not be removed for bathing unless specifically ordered by the provider. D. Encouraging the infant to crawl or bear weight on the affected leg is not appropriate until the cast is removed and healing is complete.
