Well... I wouldn't bring back much more than a thermos or two of soup, 'cause she's probably not very hungry if she's sick, and it won't be very good if you keep it a few days... the noodles'll get all mushy. And do you have a microwave or something to heat it up? If not, then I'd say one thermos.
And as for tea... well, you could just grab some teabags and make it fresh if you're in one of the houses and you have a range and such. You'd still need to grab some honey too, though.
