Which medication should be readily available for a client experiencing new-onset seizures lasting longer than 4 minutes?

• A. Intravenous midazolam
• B. Intravenous lorazepam
• C. Phenytoin IV
• D. Diazepam IV

Answer: (B)

When a seizure lasts longer than a few minutes, the priority is rapid control to prevent progression to status epilepticus. A benzodiazepine given IV is the quickest way to stop the seizure, and among them, intravenous lorazepam is preferred because it acts quickly and stays effective longer in the brain than other options like diazepam. That longer duration reduces the chance of the seizure re-emerging right after initial control, often reducing the need for multiple doses and additional monitoring in the critical early period. Midazolam can be used when IV access isn’t available, but it’s typically associated with more variable duration and respiratory monitoring needs. Phenytoin IV isn’t the first choice for immediate control—it’s used after benzodiazepines to prevent recurrence and has a slower onset with more infusion-related risks. Diazepam IV works rapidly but is redistributed quickly from the brain, so its anticonvulsant effect may wane sooner. So, having lorazepam IV readily available best addresses the need for prompt and sustained seizure cessation in new-onset seizures lasting longer than four minutes.
