A client presents to the healthcare setting with an episode of status epilepticus. Which of the following rescue medications would be utilized in this scenario to assist in stopping the client's seizures?

A. Benztropine (Cogentin) is an anticholinergic used primarily for Parkinson's disease and does not have an effect on seizure activity. B. Phenytoin (Dilantin) is an antiepileptic medication, but it is not typically used as a rescue medication for immediate cessation of seizures in status epilepticus; it is used for long-term management. C. Diazepam (Valium) is a benzodiazepine that acts quickly to stop seizures and is commonly used in acute situations, including status epilepticus, due to its rapid onset of action. D. Ethosuximide (Zarontin) is primarily used for absence seizures and is not indicated for status epilepticus.
