  18. abrupt comas are usually caused by what conditions
    • hemorrhage
    • hypoglycemia
    • trauma
    • occlusive stroke
    • heatstroke
  19. gradual comas are usually caused by what conditions

    • infection control
    • maintain adequate ventilation
  22. a patient in a coma will typically have a: high or low temperature?
    • high temperature
    • may increase due to damage of hypothalamus
  23. how will the pupils react in a metabolic coma
    they will be symmetrical reactive
  24. how will the pupils react to anoxia
    they will be bilaterally fixed, dilated
  25. how will the pupils react in a narcotic overdose
  26. how will the pupils react to a physical lesion in the brain
