Correct Answer is D
Explanation
Rationale:
A. Asking a psychiatrist to talk with the parents may not be the most appropriate immediate
action when abuse is suspected. Reporting to the authorities should take precedence to ensure the child's safety.
B. Obtaining a detailed history is important but should be done after reporting the suspected abuse to the authorities.
C. Separating the child from the parents may not be feasible or appropriate in all situations.
Reporting to the authorities is the priority action to ensure proper investigation and protection of the child.
D. Report the suspected abuse to the authorities. Suspected child abuse must be reported
immediately to the appropriate authorities, such as child protective services or law enforcement, for further investigation and intervention to ensure the safety and well-being of the child.
