Question 5 of 5
A 14-year-old girl is brought to the emergency room as her mother observed that her daughter experienced frequent impairments of consciousness lasting for about 30 seconds. Neurological evaluation indicates 'Absence seizures'. With which of the following drugs should we start treatment?
Correct Answer: C
Rationale: Ethosuximide (choice C) treats absence seizures by reducing T-type calcium currents, ideal for brief consciousness lapses. Alprazolam (choice A), Diazepam (choice B), and Midazolam (choice D), benzodiazepines, aren't first-line for absence. Ethosuximide's specificity is key.
