Assessment of a​ 21-year-old female patient 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 you place her supine on the​ stretcher, the patient quickly assumes a lateral recumbent position with her knees drawn up to her chest. Which response from the EMT would be​ appropriate?
A. ​"You can stay on your​ side, but I will need you to keep your legs straight. That will help decrease the​ pain."
B. ​"You seem more comfortable in that position. If you​ are, you should stay on your​ side."
C. ​"It would be best if you stay on your back. That position will help decrease the​ pain."
D. ​"I need you to stay on your back and with your head up. If you​ vomit, that will prevent you from​ aspirating."
