A 17-year-old client is brought to the emergency department…

A 17-yeаr-оld client is brоught tо the emergency depаrtment аfter consuming several energy shots during an all-night gaming event. Friends report the client ingested at least four 400-mg caffeine energy shots over 3 hours. The client presents with agitation, disorganized thinking, flushed face, muscular rigidity, dilated pupils, vomiting, and a heart rate of 148 beats/min. Blood pressure on arrival is 168/96 mm Hg but begins trending downward over the next hour. Shortly thereafter, the client experiences a generalized tonic-clonic seizure.Which interpretation most accurately differentiates caffeine intoxication from caffeine overdose while guiding appropriate management?
