Hospital.
Since this is a school for people with unusual powers to gather, of course we'll have a hospital! We don't want you guys getting injured with no means of getting well again. This is basically a pretty normal hospital, except the equipment is a little more high tech and able to handle pretty severe injuries. Some doctor's know healing spells as well, to help you get well even faster.
Feel free to make up your own doctor to role play as to help your character get well. There's not really a set one, so use your imagination! They can look how you want them to, and be as skilled as you wish. Though, I'd advise having them know at least a little what they're doing. Otherwise you may never recover.
Now, there are quite a few vampiric characters around, who all have their occasional thirst for blood. In order to prevent attacks on other students, there is a room full of blood pouches reserved specifically for vampires. You just have to ask, sign a paper, and be on your way. And, if you're on the go or have frequent urges, ask a doctor and you could be given a bottle of blood pills, which give the effect of drinking a full amount of real blood.
