The mother of a school-aged boy tells the practical nurse (PN) that he fell out of a tree and hurt his arm and shoulder. Which assessment should the practical nurse (PN) note as the most significant indicator of possible child abuse?

A. The abrasions on the child's arms, legs, and chest have healed: Healed abrasions indicate past injuries but do not necessarily suggest abuse unless there is a pattern of repeated or unexplained trauma. B. The mother describes in detail what she did for her injured child: Providing detailed care information shows attentiveness and is not indicative of abuse. Detailed responses may reflect concern rather than harm. C. The child looks at the floor when answering the nurse's questions: Avoiding eye contact can indicate fear, shyness, or anxiety, but it is not a definitive indicator of abuse on its own. D. The injury description by the mother varies from the child's version: Discrepancies between the caregiver’s account and the child’s report are a significant red flag for possible abuse. Inconsistent explanations about how injuries occurred warrant further investigation.
