A 5-yeаr-оld bоy wаs brоught to the clinic with signs of heаdaches, dizziness, and vomiting. During the physical examination, the nurse practitioner observed bruising on the child's arms, legs, and back. The child also appeared to be scared and refused to answer any questions. He kept insisting that he hurt his head when he fell from his bike. His mother informed the NP that the boy had a blackout a few hours earlier. The NP then suspected child abuse and notified a healthcare worker. She also recommended him for a CT scan. Based on the information given in the scenario, what would be the child's diagnosis?
