The nurse is conducting a physical examination of a child with suspected developmental dysplasia of the hip. Which finding would help confirm this diagnosis?

Rationale: A. A high-pitched "click" is heard with hip flexion or extension: A soft or high-pitched click may occur in many healthy newborns due to ligament laxity and is not specific to developmental dysplasia of the hip (DDH). It is generally considered a benign finding. B. A distinct "clunk" is heard with Barlow and Ortolani maneuvers: This is a hallmark finding for DDH. The “clunk” indicates the femoral head is either dislocating from or relocating into the acetabulum during these maneuvers, confirming hip instability and potential dislocation. C. The thigh and gluteal folds are symmetric: Symmetric skin folds suggest normal hip alignment. Asymmetry of these folds is more concerning for DDH, so symmetry would not confirm the diagnosis. D. Abduction occurs to 75 degrees and adduction to within 30 degrees (with stable pelvis): This degree of hip motion can be within normal limits, especially in the absence of instability. Restricted abduction is more consistent with DDH in older infants.
