Which clue in the evaluation of pediatric trauma would most strongly suggest abuse rather than an accidental injury?

• A. The child cannot recall how the injury occurred.
• B. The parents are calm in the emergency department.
• C. The injury is highly unusual for a child of that age.
• D. The child was doing something unsafe when the injury occurred.

Answer: (C)

A finding that an injury is highly unusual for the child’s age is the strongest clue for abuse because injuries must align with what a child can do at that developmental stage. If a young, non-ambulatory child has a fracture or injury that requires a level of force or a mechanism that would not be expected from typical play or activities at that age, it raises suspicion that someone else caused it. In contrast, not remembering how the incident happened can occur from fear or confusion, calm parental behavior in the ED is not itself diagnostic, and an injury occurring during unsafe activity can still be accidental if the activity is plausible for the child’s age.
