Diazepam is the drug that the nurse would expect to be ordered for use in emergency control of status epilepticus.
Step-by-step explanation:
The drug that the nurse would expect to be ordered for use in emergency control of status epilepticus is diazepam. Diazepam is an anticonvulsant medication that is commonly used to treat seizures, including status epilepticus. It works by increasing the inhibitory effects of the neurotransmitter GABA in the brain, which helps to reduce abnormal electrical activity and control seizures.
