Onsent for medical treatment of a minor in the state of Nevada

This is for a case study and I am unable to locate the information. I need the Nevada statute for treating a minor in a physical abuse case. Basically as a doctor what does the Nevada statute tell me about treating a minor that comes to the office and says they have been physically abused by her parents. Do I still need permision from her parents to treat her? I need the actually statue number. It only has to be one page, Thanks.
