      3. Symptoms of shock

         1. Compensatory

            1. Anxiety: when circulation lacks, the patient becomes

            2. Pale: the brain robs it from skin first

            3. Shortness of breath: it speeds up the respirations

            4. Fast heart rate: it speeds up the heart

            5. Weakness: the muscles are being deprived of circulation

            6. Nausea: stomach being deprived of circulation also.

         2. Decompensatory

            1. Thirst: due to the lack of fluids

            2. Confusion: the brain has already tried everything

            3. Increased deep respirations: due to the build up of acids

            4. Unconsciousness: the brain shuts itself down to conserve

            5. Low blood pressure: acids have filled the cells to death

      4. Assessment of shock

         1. Perform a primary assessment and administer 100% oxygen

         2. Treat the injury that is causing the shock
