The RN helps Billy take off his shirt and notices that he has bruises in multiple stages of healing on his back. The nurse asks Billy how he got the injuries, and Billy says, "I don't know." The grandmother states, "He falls a lot." Which action should the RN take first?
1) Document the findings and report them to the healthcare provider
2) Ask the grandmother for more information about Billy's falls
3) Assume that Billy is being abused and report it to the appropriate authorities
4) Perform a thorough physical examination of Billy to assess for other signs of abuse
