These episodes last for several seconds and occasionally his eyelids flutter. He was born at term and has no history of serious illness. He has met all his developmental milestones. He appears healthy. Neurologic examination shows no focal findings. Hyperventilation for 30 seconds precipitates an episode of unresponsiveness and eyelid fluttering that lasts for 7 seconds. He regains consciousness immediately afterward. An electroencephalogram shows 3-Hz spikes and waves. Which of the following is the most appropriate pharmacotherapy for this patient?? A: Clonazepam, B: Carbamazepine, C: Ethosuximide, D: Phenytoin, E: Levetiracetam,  <response>: This is a clinical vignette describing a 7-year-old boy with episodes of staring blankly and eyelid fluttering, lasting several seconds. These episodes are precipitated by hyperventilation. EEG shows 3 Hz spike-and-wave activity, consistent with absence seizurespetit mal epilepsy. The question asks to identify the most appropriate pharmacotherapy. Since this patient has absence seizures, ethosuximide would be the best choice as it is considered first-line for absence seizures. Clonazepam could potentially be used but is not preferred first-line. Carbamazepine, phenytoin, and levetiracetam are not considered first-line options for absence seizures.C: Ethosuximide
