The parent of an school-aged child tells the practical nurse (PN) that the child fell out of a tree and hurt the child's arm and shoulder. Which assessment finding should the PN note as the most significant indicator of possible child abuse?

A. The parent's version of the injury is different from the child's version: Inconsistent histories are a red flag for abuse and require further investigation. B. The child has several abrasions on the chest and legs: Abrasions alone can occur with falls; they are not specific to abuse without suspicious patterns or locations. C. The child looks at the floor when answering the nurse's questions: Avoidance may be due to shyness or fear but is not conclusive for abuse. D. The parent refuses to answer questions about family history: While uncooperative behavior may be concerning, it is less direct than inconsistent injury accounts.
