Which of the following is a common symptom of pediatric migraine?

Nausea and vomiting are indeed common symptoms associated with pediatric migraines. In children, migraines can present differently than in adults, but gastrointestinal symptoms like nausea, vomiting, or abdominal pain frequently accompany the headache episodes. This may be due to the role of the central nervous system and its interplay with the gastrointestinal system during a migraine attack.

In contrast, options such as increased appetite, fever, and severe fatigue are less typical for migraine presentations in children. Increased appetite is not usually linked to migraine but rather more associated with other conditions or hunger. Fever suggests an infectious process, which is not characteristic of migraines, as migraines do not typically cause systemic illness. Severe fatigue can occur post-migraine due to the exhaustion that follows a headache, but it is not a primary symptom that helps identify a migraine during the active phase of the headache. Thus, nausea and vomiting stand out as key indicators of pediatric migraines.
