In status epilepticus, which medication should the nurse administer immediately?

• A. Lorazepam IV
• B. Diazepam IV
• C. Phenytoin IV
• D. Valproic acid IV

Answer: (A)

Rapid seizure control is the priority in status epilepticus, and benzodiazepines act fastest by enhancing GABA activity to stop ongoing neuronal firing. Among IV options, lorazepam is preferred because it provides quick action and tends to have a longer duration than diazepam, making the seizure less likely to recur right away. Diazepam can work rapidly too, but its effects fade sooner due to redistribution into fat tissue, often necessitating additional dosing. Phenytoin and valproic acid are important for ongoing management, but they don’t terminate an active seizure as promptly as a benzodiazepine. So, giving lorazepam IV immediately is the best first step to rapidly halt the seizure activity.
