An Emergency Medical Responder (EMR) quickly checks the breathing and pulse of a patient with Alzheimer's disease who has been sleeping outside in the cold for several hours. The EMR informs you that the patient grimaces to painful stimuli but is not breathing and does not have a pulse. What is your best response?

A) "Let's get the automated external defibrillator ready and apply it to the patient."
B) "Someone start CPR, but do not insert an oral airway since this can cause ventricular fibrillation."
C) "We need to contact medical direction to see what the doctor wants us to do since the patient is hypothermic."
D) "Let's perform the primary assessment again, and this time take longer to assess for breathing and a pulse."
