Which of the following injury patterns is MOST suggestive of child abuse?

Bruises on the abdomen are considered the most suggestive of child abuse due to the nature and location of the injury. The abdomen is typically a protected area, and bruising in this region can indicate trauma that is not usually associated with typical childhood accidents. Children often fall or experience injuries on their extremities, like arms and legs. In contrast, bruises on the abdomen could be a sign of forceful impact suggesting potential abuse, especially when they appear in patterns or are inconsistent with the explanation provided by caregivers.

Lacerations or bruises in more common locations, like the chin or lower leg, can occur due to typical childhood activities and do not raise immediate red flags regarding abuse. Burns with splash marks could suggest an accident or a specific type of burn, but the nature of the burn would need further context to determine if it indicates abuse. In summary, the presence of abdominal bruises warrants a high level of suspicion for child abuse and should prompt further investigation.
