Q

You receive a call to a residence for a patient who is “sick.” Upon arriving at the scene, you find the patient, a 39-year-old woman, lying on the couch with a wet washcloth on her forehead. She is conscious and alert, and tells you that she has had several episodes of diarrhea and noticed bright red blood in her stool. Her pulse rate is rapid and weak, her skin is cool and clammy, and her blood pressure is 98/58 mm Hg. Her medical history is significant for hemophilia, for which she is receiving factor VIII therapy. As you pull out a non rebreathing mask, she tells you that her husband will be home in a few hours and that he will take herto the hospital. You should:

A. notify her husband, explain the situation to him, and advise him that you will be transporting his wife to the hospital.
