You are seeing an 8 year old boy brought in by ambulance for a first time unprovoked afebrile seizure. The seizure was generalized tonic-clonic and lasted 3 minutes then self-resolved. The child is now back to baseline. A thorough history and physical exam has revealed no clear etiology for the seizure, and the neurologic exam is normal. The child was well prior to the seizure and has no significant past medical history. Blood glucose in the field was 98. The child is well-appearing and can easily obtain follow-up with his primary physician in a timely fashion. 

Which of the following is indicated?
