You Are on the Scene of a Call for an Injured

You are on the scene of a call for an injured woman. Your scene size-up did not reveal any indications of danger. On assessing the patient, she tells you that she was beaten with a telephone receiver by her estranged husband. Before you can request law enforcement assistance, the husband returns with a baseball bat and threatens to kill you if you don't leave the house and states, "She's staying here," in reference to the patient. The assailant is standing with the bat held above his shoulder, ready to swing. Which of the following is the best course of action?

A) Try to reason with the husband, using the techniques you learned for dealing with behavioral emergencies, while your partner goes outside to request law enforcement.
B) Retreat from the residence, leaving the patient behind; move your vehicle away from the address; and request law enforcement.
C) Carry out the "take-down" approach you and your partner have practiced for such a situation.
D) Inform the assailant that you will leave but that you have to take the patient with you.
