Description
You are accompanying the Emergency Department registrar when a 24 year old NZ European woman is brought in by a friend. She is drowsy but adamant that she does not want to be in the hospital. Her friend informs you that she was found surrounded by empty paracetamol packs and an empty bottle of vodka. The friend is unable to tell you how long ago she took the pills but they report that she does suffer from depression (though isn't sure if she is prescribed antidepressant medication). When you approach the patient she becomes irritable and demands to leave the hospital, yelling at you that she does not need treating.
