Correct answer: B — Blood glucose and investigations for the fever source only

A simple febrile seizure (generalised, duration <15 minutes, single episode in 24 hours, in a developmentally normal child aged 6 months – 5 years) does not require neuroimaging, EEG, or lumbar puncture. Investigation should focus on identifying the fever source. Blood glucose should be checked. LP is only considered if there are signs of meningitis.
