Final answer:
Lisa, as a preschool teacher, is legally required to report any signs of child abuse to the appropriate authorities. Personal intervention is not her role, and failure to report can have legal consequences.
Step-by-step explanation:
When Lisa, a preschool teacher, discovers that a child in her care is being abused, she is required to report the incident. As mandated reporters, teachers have a legal responsibility to contact either law enforcement or social services when there are signs of child abuse. This action is crucial in initiating the process that may protect the child and provide them with the necessary help and support.
Failure to report such incidents can result in legal consequences for the teacher and further endanger the welfare of the child. It is not Lisa's role to personally stage an intervention or to decide whether or not the child's disclosure is true. Her responsibility is unequivocally to report the incident to the appropriate authorities.
