You are dispatched to a residence for a report of a "man down." Upon arrival, you find a well-kept home with the door open, and a van in the driveway with "palliative care specialist" printed on the side. As you enter the home, a woman meets you and says, "It's my mother. She has terminal cancer and we can't seem to wake her up." Which of the following questions would be most appropriate to ask at this time?
a. "Did anyone check for a pulse?"
b. "What type of cancer does your mother have?"
c. "Is your mother receiving hospice care?"
d. "What hospital does she normally go to?"

In a situations of a "man down" report we first want to be sure whether the person is still alive. On the field, this can be assessed by checking for person's vitals; respiration and pulse and also checking for pupillary reflex.

Further actions depend on the findings of these preliminary examinations.

In this case, you recieved information regarding patient's history and that she is the user of palliative care service. This suggest a serious condition which, together with the inability to wake the patient, brings the importance of assessing her vitals.

Other given answers are irrelevant at the time, considering the given situation.
