MSFinals-4211

A 16-year-old girl is brought to the Emergency Department after overdosing on alcohol and paracetamol. She was discovered by her friend, unconscious in a local park, after sending a concerning text message. Her parents were both at work at the time. Upon regaining consciousness, she expresses embarrassment and explains that she had an argument with her boyfriend, now regrets her actions, and wishes to return home. All of her blood tests come back normal and she is deemed medically stable.
What is the best course of immediate action for her management?
