Which injury type is specifically noted as rare outside abuse and may serve as an early warning sign of abuse?

• A. Sentinel injuries
• B. Internal organ lacerations
• C. Bone fractures from accidents
• D. Head injuries from sports

Answer: (A)

Sentinel injuries are minor, often easily overlooked injuries that occur in infants or very young children who can’t explain them away. They’re considered rare in accidental injuries and are taken as important early warning signs that abuse may be occurring. Because these injuries can precede more serious harm, they prompt investigators to conduct a thorough safety assessment, review the caregiver–child interactions, and consider protective actions to prevent further harm.

Internal organ lacerations are severe injuries usually tied to significant trauma and aren’t described as rare outside abuse or as early indicators. Bone fractures from accidents can happen, but in very young children they’re more likely to have plausible accidental explanations. Head injuries from sports are common in athletic contexts and don’t function as red flags for abuse in the same way sentinel injuries do.
