Final answer:
The most accurate and critical information to include in reports of child abuse involves the child's age, the nature and extent of injuries, and any actions taken in response to the incident.
Step-by-step explanation:
When making written reports of abuse, the most critical information to include typically describes the nature of the witnessed or suspected abuse. The report should contain key details such as the child's age, the nature and extent of the injuries observed, and any immediate actions that have been taken in response to the incident. Specifically, the correct answer to the student's question is that the report should provide an account of the child and the situational context: the child's age, the nature and the extent of the injuries, and any actions taken to protect the child or to report the incident to the proper authorities.
