Explanation
Choice A is correct. Lorazepam is a benzodiazepine that acts as an anticonvulsant. It is often used as a first-line medication to abort prolonged or status epilepticus seizures, including tonic-clonic seizures. Lorazepam has a rapid onset of action and can be administered intravenously or intramuscularly in emergency situations to quickly terminate the seizure.
Choice B is incorrect. Phenytoin is an anticonvulsant, but its onset of action is slower compared to benzodiazepines like lorazepam. It is more commonly used for long-term seizure control and is not the first choice for rapidly terminating an ongoing seizure.
Choice C is incorrect. Similar to phenytoin, carbamazepine is used for long-term seizure control and is not appropriate for rapidly stopping an acute tonic-clonic seizure. It has a slower onset of action.
Choice D is incorrect. Benztropine is not an anticonvulsant. It is typically used to treat extrapyramidal side effects caused by antipsychotic medications and is not indicated for seizure management.
