## Why Option 1 is correct The 2015 ILAE operational definition of status epilepticus (SE) defines T1 as the time point at which treatment should begin: **5 minutes of continuous seizure activity OR ≥2 seizures without recovery between them**. The EEG pattern marked **A**—continuous generalized rhythmic spike-and-wave discharges—is the hallmark electrographic finding of convulsive SE. The first-line pharmacologic agent for SE is **IV lorazepam 0.1 mg/kg (maximum 4 mg)**, which should be administered immediately upon recognition of SE at the T1 threshold. This is supported by the Glauser et al. AES Guideline and Harrison's 21st edition. ## Why each distractor is wrong - **Option 2**: T1 = 10 minutes is incorrect; the ILAE definition specifies T1 = 5 minutes. Fosphenytoin is a Stage 2 agent (given after benzodiazepines if seizures persist), not first-line. - **Option 3**: T1 = 30 minutes is actually T2 (the point beyond which long-term sequelae become likely), not the treatment initiation threshold. Levetiracetam is a Stage 2 alternative, not first-line. - **Option 4**: T1 = 2 minutes is too early and not part of the ILAE definition. Propofol is a Stage 3 agent reserved for refractory SE requiring continuous anesthesia, not initial management. **High-Yield:** Remember the ILAE SE definition: T1 = 5 minutes (treat now with IV lorazepam); T2 = 30 minutes (refractory SE, escalate to anesthetics).
