Final answer:
The school nurse should review the DNR order, document it, and discuss it with the parents. A plan should be developed for emergency situations.
Step-by-step explanation:
The school nurse should first review the do not resuscitate (DNR) order and ensure that it is properly signed and valid. The nurse should also document the order in the child's medical records and discuss the order with the child's parents or guardians to ensure a clear understanding of their wishes and any specific instructions. Additionally, the nurse should collaborate with the school administration and teachers to develop a plan for how to respond in the event of an emergency.
