As our district's only school nurse (RN) if there's a doctor's order on file stating that rectal Diastat is to be given if a 'lesser' (ie. staring) seizure lasts X number of minutes or progresses to a grand mal (or initiates as grand mal) then I have no problem giving the Diastat and then calling the preferred ambulance company and the family. The superintendent has given me carte blanche to call the EMT's at any time I feel it's needed even if the parent's indicate they're coming and to wait for them to get there.... if I feel it's needed I'll call, as then, if somethng should happen, they can't blame me... and the doctor ordered medicine will also have been administered as ordered so I'm fully covered.
