Resident having seizure

Ok so the other night at work one of my residents had a seizure........i grabbed the nurse and she told me to get her a cold towel......so i brought her a towel.....then she started wiping the residents face with it and slapping his face .......then she had me roll up the head of his bed........after the face slapping she droped the side rails and told me we needed to sit him up......im like....he is sitting up....." no we need to sit him all the way up so he doesnt swallow his tounge"......after that i asked her if she was crazy..........the resident had stoped convulsing but he was still breathing funny and his eyes were rolled back in his head.......this resident can not support any of his body weight and i asked her what we were supposed to do if he started convulsing again and we dropped him.........she was like "what do u think we should do?"......I said put him back in bed roll the head down and turn him on his side........oh and lets not forget ...keep the side rails up.........but what do i know im just a cna.......i refused to sit him on the edge of the bed though but im not sure if im in the right.......what should i do if this happens again????? Has anyone ever heard of a pt swallowing there tounge??
