Final answer:
The nurse should first provide emotional support to the parents of the school-age child who has sustained brain death due to a bicycle crash. Explaining the legal process of organ donation and facilitating a meeting with the organ procurement team should follow providing emotional support. Respecting the family's decision without further discussion is not appropriate.
Step-by-step explanation:
The nurse should first provide emotional support to the parents. Dealing with the brain death of their child can be an extremely distressing experience for the parents, and they need support and understanding during this time.
While explaining the legal process of organ donation (Option B) and facilitating a meeting with the organ procurement team (Option C) are important actions, they should follow providing emotional support to the parents.
Respecting the family's decision without further discussion (Option D) is not appropriate in this situation. The nurse should offer guidance, information, and support to help the parents make an informed decision about organ donation.
