A nurse is caring for a child who reports migraine headaches for the past 4 months. Which of the following actions should the nurse take first?

A. Review the child's electronic pain diary: This should be the first action as it provides valuable information about the frequency, triggers, duration, and severity of the headaches. It helps the nurse and provider make informed decisions about treatment and next steps. B. Request a change in medication from the provider: Medication changes should be based on a thorough assessment of the child’s headache pattern and response to current therapy, which starts with reviewing documented data. C. Set up an appointment with the school nurse: While coordination with the school is important for managing chronic conditions, it is not the priority action before understanding the nature and pattern of the headaches. D. Refer the family to a chronic pain support group: Support groups are helpful in long-term management, but should follow a thorough assessment and diagnosis of the child’s condition and needs.
