Assessment of a 21-year-old female reveals her to have severe abdominal pain localized to the right upper quadrant. She is alert and oriented and her vital signs are stable. After placing her supine on the stretcher, she quickly assumes a lateral recumbent position with her knees drawn up to her chest. Which response from the EMT would be appropriate?

A) "It would be best if you stay on your back. That position will help decrease the pain." B) "You can stay on your side, but I will need you to keep your legs straight. That will help decrease the pain." C) "I need you to stay on your back and with your head up. If you vomit, that will prevent you from aspirating." D) "Are you comfortable in that position? If you are, you should stay on your side."
