When planning home care for a child with juvenile rheumatoid arthritis (JRA), which recommendation should the nurse provide to the child's parents?

A. Decreasing motion of affected joints before bedtime may increase stiffness and discomfort in the morning. B. Exercising joints before getting out of bed without first loosening them with heat can cause pain and limit participation. C. Completing the exercise program immediately upon awakening before heat application can be painful for stiff joints. D. Placing the child in a warm bath before any activity helps relax muscles, reduce stiffness, and improve range of motion, making morning activities and exercise easier and less painful.
