You have chosen to treat with oral trimethoprim.

After no small amount of persuasion, Shani swallows the liquid. You send her up to the ward.

Half an hour later the ward staff call you. She is fitting again, and her fever is still 38.5 C. The staff are wondering why you thought that a seriously ill infant would be best treated with an oral antibiotic useful for UTI's.

Good question.
