It has been a quite Saturday night. Just after the bars close, you receive a report for an injured woman who has fallen. Your dispatcher reports she heard a man swearing loudly in the background while she was talking to the patient. As you and your partner approach the house, you are met by a 30 year old man who appears to be agitated. He quickly tells you everything is alright and that there is no need for medical assistance. He tells you no one from this house called for assistance. As you glance in the front door you see a woman who has some abrasions on her face. She appears to be crying quietly. Her blouse appears torn.

What are initial priorities in this case?
How should you proceed with treating the injured woman?
