A) The use of a long spine board without a cervical collar is recommended because cervical collars do not achieve a full degree of immobilization B) Current out-of-hospital management of potential spinal injury lacks evidentiary scientific support C) A review of the related literature has demonstrated clinical support for ongoing use of spine motion restriction equipment in all patients with either a minor or major mechanism of injury D) Only a licensed and board-certified emergency department physician is capable of determining whether spine motion equipment is necessary

At this time, you try:
