What is an appropriate intervention for the edematous child with reduced mobility related to nephrotic syndrome?

A. Keep edematous areas moist and covered. Keeping edematous areas moist and covered can worsen edema by trapping moisture and heat, leading to increased swelling. B. Reach the child to minimize body movement. Minimizing body movement is not appropriate as it can lead to muscle weakness and stiffness. Encouraging gentle movement and position changes is beneficial. C. Change the child's position frequently. Changing the child's position frequently helps prevent complications such as pressure ulcers and improves circulation, which can aid in reducing edema. D. Keep the head of the child's bed flat. Elevating the head of the bed can help reduce edema by promoting venous return and reducing fluid accumulation in dependent areas.
