For a 15-year-old girl presenting with fever, headache, and altered mental status, what condition should be highest on the differential diagnosis list?

• A. Viral infection
• B. Meningitis
• C. Dehydration
• D. Severe migraine

Answer: (B)

In the case of a 15-year-old girl presenting with fever, headache, and altered mental status, meningitis should be the highest condition on the differential diagnosis list due to the acute and serious nature of this illness. Meningitis is an infection of the protective membranes covering the brain and spinal cord, and it can present with fever and severe headache, as well as neurological symptoms such as altered mental status. The combination of symptoms—fever, headache, and altered mental status—raises significant concern for central nervous system involvement, which is characteristic of meningitis. Immediate recognition and treatment of meningitis are critical, as it can progress rapidly and lead to severe complications, including brain damage or death if not addressed promptly. While viral infections can cause similar symptoms and are often a consideration, the presence of altered mental status elevates the suspicion for meningitis as a more urgent diagnosis. Dehydration and severe migraines, while possible causes of headache, do not typically include the combination of fever and altered mental status to the same alarming degree and therefore would not take precedence over the consideration of meningitis in such a clinical presentation.
