During a family session, it is revealed that an older child has sexually assaulted a younger child. Both children live in the same home with their parents. What is the PMHNP's next step?

Choice A reason: While law enforcement may eventually be involved, the immediate priority is child safety and mandated reporting. Arresting the older child without a full assessment may not be developmentally appropriate or trauma-informed. Choice B reason: Calling 911 may be necessary in cases of acute danger, but in this scenario, the PMHNP should first ensure safety and follow mandated reporting protocols. Emergency services are not the first-line response unless there is imminent risk. Choice C reason: Involuntary psychiatric hospitalization requires specific criteria, including danger to self or others and inability to care for oneself. While the older child may need evaluation, this step is premature without a full assessment and proper reporting. Choice D reason: This is the correct and legally mandated response. The PMHNP must ensure the younger child is protected and report the incident to child protective services. This initiates a formal investigation and ensures both children receive appropriate care and intervention.
