A nurse in an emergency department is assessing a client for suspected cocaine intoxication. Which of the following findings should the nurse expect?

Choice A reason: Cocaine is a stimulant that causes sympathetic nervous system activation. Dilated pupils are a classic sign of intoxication due to increased adrenergic activity. Choice B reason: Depression is more commonly seen during cocaine withdrawal, not intoxication. Intoxication produces euphoria, agitation, and hyperactivity. Choice C reason: Nystagmus is associated with intoxication from substances like phencyclidine (PCP), not cocaine. Choice D reason: Hypersomnia occurs during withdrawal when the body crashes after stimulant use. Intoxication produces insomnia and hyperactivity instead.
