A nurse is assessing a 5-month-old Infant who has had a seizure and high pitched crying with a high fever. The nurse anticipates the need for which diagnostic testing?

A. A CT scan is typically used to evaluate structural issues in the brain, such as tumors or bleeding, rather than infections like meningitis. B. An EEG is used to diagnose epilepsy or other seizure disorders, but it would not help in diagnosing the cause of a febrile seizure related to a possible infection. C. In a 5-month-old with a seizure and high fever, meningitis is a critical consideration. The analysis of CSF through a lumbar puncture is required to confirm or rule out meningitis. Fever with a seizure in infants may indicate an infection such as bacterial or viral meningitis, making CSF analysis essential. D. While blood cultures can help identify an infection, CSF analysis is more specific in cases of suspected meningitis, as it directly tests for infection in the central nervous system.
