The patients mother says that the child was lying on the bed and must have fallen onto the carpeted floor. She lives at home with her mother and her 3-month-old brother. When the patient is directly asked what happened, she looks down at the floor and does not answer. Past medical history is noncontributory. Physical examination shows that the patient seems nervous and has noticeable pain upon palpation of the right thigh. A green-colored bruise is also noted on the childs left arm. Radiographs of the right lower extremity show a femur fracture. Which of the following is the next best step in management?? A: Check vitamin D levels., B: Check copper levels., C: Collagen biochemical testing, D: Obtain a complete skeletal survey to detect other bony injuries and report child abuse case., E: Run a serum venereal disease research laboratory VDRL test.,  <response>: This is a clinical case scenario involving a 3-year-old girl brought to the emergency department with inability to walk and right thigh pain and femur fracture. The history provided by the mother of a fall from the bed seems inconsistent with the injury. The patient also appears nervous and avoids answering directly when asked what happened. She has noticeable bruising on her left arm. This raises suspicion for possible child abusenonaccidental trauma. The choices provided include checking vitamin D, copper, collagen, getting a skeletal survey, and VDRL. The skeletal survey is the best next step as it can help detect other occult bony injuries that may indicate abuse. The other tests are irrelevant in this setting. Reporting the suspected child abuse case is also important.D: Obtain a complete skeletal survey to detect other bony injuries and report child abuse case.
