-splint fractures and elevate if well stabilized
-avoid rough and excessive handling that may cause additional injury
-prevent loss of body heat. if possible, a blanket should be placed under the victim as well as on top.

-do not give the victim anything to eat or drink. any ingestion may result in choking or vomiting, which can cause additional problems
-record vital signs, such as pulse, blood pressure, and respiration rate every 5 minutes
-constantly reassure the victim
-activate the EMS system so that help can arrive quickly |
