TMI: scared, help my friend was raped

So last night, my friend was raped, for her personal confidentiality, I will not reveal to many details. All I know is that it was unprotected, she is under 18 (not by much), and   she was high. I could imagine she refuses to tell any of her parents because she snuck out in the middle of the night, however the rape was not her fault, it was just a very bad situation. I currently do not know what to do, her friends and I are worrying about her well-being, we all want her to seek medical attention asap for STD's and for pregnancy, but please do not post any rude comments, I just need to giv her some advice on how she should approach this. Im sorry there wasn't much detail, but please work with me.
