Trash snake care help

Hello, I have come to own a snake very suddenly. She was left out in the cold for an undetermined amount of time next to the trash in a broken tank. I moved her into my ten gallon fish tank because there was broken glass in hers.

I got some emergency care advice from r/snakes. But would like to know if i need to know any specifics. Can you fuys give me a run down on what i should be getting at the pet store? I have a 55 i am draining to transfer her into when she's stable. Thanks!
