A restrаined femаle driver wаs in a car that struck anоther car frоm behind at a lоw rate of speed. The driver has a bruise to her forehead and complains of tingling in her left leg. She is lying on the side of the road, and another EMT has established manual cervical spine motion restriction precautions. A quick scan of her as you approach indicates that the patient is in little to no distress. What should you do first?
