The nurse is performing an admission assessment for a newborn who has asymmetrical buttocks. Which assessment test results should the nurse report to the healthcare provider?

A. Plumb line test indicates fetal position curvature: This assessment is used to evaluate spinal alignment and posture, not hip integrity. It does not explain asymmetrical buttocks in a newborn. B. Ortolani maneuver causing a click at the hip joint: A positive Ortolani sign (a “click” or “clunk”) indicates hip dysplasia or subluxation. This finding is significant and should be reported to the healthcare provider for further evaluation and management. C. Babinski test that reveals fanning out of toes: The Babinski reflex is normal in newborns and does not indicate musculoskeletal abnormality. It is unrelated to asymmetrical buttocks. D. Moro test precipitating a startle response: The Moro reflex is a normal newborn response and does not indicate hip instability or asymmetry in the buttocks.
