Answer

Ruling out metabolic or drug-induced causes of symptoms consistent with a transient ischemic attack (TIA) is important. Initial assessment is aimed at excluding emergency conditions that can mimic a TIA (eg, hypoglycemia, seizure, or intracranial hemorrhage). A fingerstick blood glucose test should be performed and blood drawn for a complete blood count (CBC), coagulation studies, and serum electrolyte levels. Obtain a 12-lead electrocardiogram (ECG) with rhythm strip, and evaluate for symptomatic arrhythmias or evidence of ischemia.
