NSG-3280 EXAM 3 GRADED A+
1. primary injury: initial damage to the brain that results
from the traumatic 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 brain: the more tissue that
is attected/gone (Time is tissue)
4. The three types of mechanisms of brain injury: ischemia, hypoxia,
increased ICP
5. The three compartments of the cranium include:: Brain tissue,
CSF, and blood
6. The normal range of ICP is: 0-15mm Hg
7. If one of the compartments in the cranium increases, what
happen to the other two parts?: they decrease
8. If all three of the compartments of the cranium while one
,of the compart-ments is increased, what can happen?: Possible
brain herniation
9. What could happen if there is a sudden decrease in CSF fluid?:
Brain herniation
10. If the patient has increased ICP, should you do a lumbar
puncture?: Hell no
11. delirious: in an acutely disturbed state of mind resulting from illness or
intoxication and characterized by restlessness, illusions, and incoherence
of thought and speech.
12. Obtunded: Less than full alertness (altered level of consciousness),
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 posturing, may occur
15. Decorticate posturing: Contractures toward their core
16. Decerebrate posturing: posturing in which the neck is extended with
jaw clenched; arms are pronat-ed, 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
