1. primary injury initial damage to the brain that results from the trau-
matic event
not reversible
2. secondary injury an insult to the brain subsequent to the original
traumatic event
progressive with delayed cell death
3. The more time that the injury effects the more tissue that is affected/gone (Time is tissue)
the brain
4. The three types of mechanisms of ischemia, hypoxia, increased ICP
brain injury
5. The three compartments of the cra- Brain tissue, CSF, and blood
nium include:
6. The normal range of ICP is 0-15mm Hg
7. If one of the compartments in the they decrease
cranium increases, what happen to
the other two parts?
8. If all three of the compartments of Possible brain herniation
the cranium while one of the com-
partments is increased, what can
happen?
9. What could happen if there is a sud- Brain herniation
den decrease in CSF fluid?
10. If the patient has increased ICP, Hell no
should you do a lumbar puncture?

11. delirious in an acutely disturbed state of mind resulting from
illness or intoxication and characterized by rest-
lessness, illusions, and incoherence of thought and
speech.
12. Obtunded Less than full alertness (altered level of conscious-
ness), typically as a result of a medical condition or
trauma.
Falls asleep unless stimulated
13. Stuporous Deep states of sleep: vigorous stimulation is required
but pt cannot stay awake
14. comatose Unable to be aroused, even with vigorous painful
stimuli; motor responses,such as withdrawal or pos-
turing, may occur
15. Decorticate posturing Contractures toward their core
16. Decerebrate posturing posturing in which the neck is extended with jaw
clenched; arms are pronated, extended, and close
to the sides; legs are extended straight out; more
ominous sign of brain stem damage. Most Severe.
17. dysconjugate gaze paralysis of gaze or lack of coordination between the
movements of the two eyes
18. ocular palsies One or more cranial nerves dysfunctional such that
motor paralysis of the eye impairs movements in one
or more directions
19. Doll's eye reflex

when you move the head, the eyes should move, then
return to a central position; in some brain injuries,
the eyes will be fixed centrally
20. cold calorics test tests for brain stem function with cold water. Eyes
should divert to side where cold water is being put
on
21. coup injury brain injury at the site of impact
22. contracoup injury brain injury on the opposite side of impact
23. GCS is taken first________ hours after 48
a TBI
24. The primary injury after a TBI is a hematoma:
epidural
Subdural
Subarachnoid
WHICH CAN CAUSE INCREASE OF ICP
25. Collection of blood between the epidural hematoma
dura and skull
LOC can be normal and then rapidly
decreases
26. Collection of blood between the Subdural hematoma
dura and outer layer of arachnoid
membrane: typically involves bridg-
ing veins
Slower onset / prone to rebreeding
