Make sure you get pain relief to take home with you afterwards
this ^ it may cost extra but a good vet will send you home with painkillers. If they dont ask for it or the 24 hour pain killer will run out the day after and your bun will be in pain. You dont give the pain killer till the day after and you have to make sure they have eaten before you give it to them.
If you use hay, straw etc... for their bedding/floor then you need to replace that with blankets, towels etc.. something nice and soft for her to lay on. put some hay and grass in the corner for her to eat but thats about it, she will pee and poo where she sits so if shes litter trained dont worry when she does this.
you need to do this as you dont want her getting an infection from the hay and other bedding and the blanked and towels are more comfortable for the bun.
You need to ensure you have the buns favourite veggie/fruit ready as she may not want to eat but needs too and its easier to tempt her with her fave foods. You may need to wave food in her face and place it against her lip to convince her to eat
If she doesnt eat by the next morning mush up pellets in water and syringe feed it to her she will not like this but you will need to get food in her. This means she gets food and water at the same time. You can then also give her the pain killers. Then If shes not eating by the afternoon then take her back to the vet.
Dont worry shes going to be tired, sore and probably wont move around much, she will be dopey and may not move around until the evening after and some buns take 2-3 days till they are more active
