Final answer:
The nurse obtains a copy of the child's x-ray report to prepare a physical education plan for a child with Down syndrome.
Step-by-step explanation:
The school nurse obtains a copy of an x-ray report of the child's skeletal system before preparing a physical education plan for a child with Down syndrome.
The x-ray report helps the nurse assess any musculoskeletal abnormalities that may impact the child's physical activities, such as congenital dislocations or bone deformities.
The nurse can then tailor the physical education plan to accommodate the child's specific needs and ensure their safety and well-being during exercise.
