ADULT HEALTH III: EXAM #3: TRAUMATIC BRAIN INJURY
QUESTIONS AND CORRECT EXPLAINED ANSWERS 2026|| 100%
GUARANTEED PASS!! <RECENT VERSION>
1. shearing head injury-CORRECT ANSWER- Rotational Forces
occurs when the brain shifts and rotates inside the skull, causing the stretching and tearing of
nerve fibers (axons)
The brain, being a soft tissue within the rigid skull, moves differently than the skull during these
events. This difference
in movement causes the brain's tissue to stretch and tear, especially the long connecting nerve
fibers
2. twisting head injury-CORRECT ANSWER- Rotational Forces
occurs when the brain is subjected to rotational forces, such as those experienced in car
accidents, falls, or violent
shaking
cause the brain to move rapidly back and forth, leading to the brain bouncing around or twisting
within the skull. This
movement can stretch, tear, and damage the brain's nerve fibers (axons).
3. diffuse axonal injury-CORRECT ANSWER- Rotational Forces
widespread damage occurs to the brain's axons, disrupting communication between nerve
cells.- can lead to coma, prolonged unconsciousness, and permanent disability
4. blood vessel dissection-CORRECT ANSWER- Rotational Forces
a tear in the inner lining (intima) of an artery, allowing blood to flow between the layers of the
artery wall, (forms an
intraumural hematoma) potentially leading to a blood clot or stroke.
5. contusion, swelling, blood clots, epidural and subdural hematomas-CORRECT ANSWER- What
are four
secondary injuries to the brain that fall under "contrecoup" or "counter-blow" injuries?
, 6. primary injury-CORRECT ANSWER- Phases of Injury-CORRECT ANSWER-
stretching, compression and tearing of tissues and blood vessels
7. changes in cerebral circulation, inflammation, glutamate toxicity, mitochon
drial dysfunction, changes in BBB, increase ROS production-CORRECT ANSWER- Phases of Injury-
CORRECT ANSWER-
What are six secondary injuries that should be prevented at all costs when dealing with head
trauma?
8. stroke related to basilar artery damage-CORRECT ANSWER- What additional complication
should be associated with
a basilar skull fracture?
9. facial palsy, numbness, possible deafness, nystagmus-CORRECT ANSWER- Because basilar
skull fractures can
damage the the foramen that cranial nerves pass through, what sort of s/s would you expect
related to this injury? (4).
10. beta-2 transferrin, beta-trace protein-CORRECT ANSWER- Which two proteins can be tested
for to determine if there
is CSF leakage?
1/4

11. lack of delivery of oxygen and nutriends to the spinal cord and brain, inap
propriate shifting of brain tissue-CORRECT ANSWER- What are two things that can be result
from significant CSF leakage?
12. airway complications due to downward pressure on the brainstem-CORRECT ANSWER-
Because a
significant loss of CSF causes shifting of brain tissue, what complication should be addressed as
a result of these
changes?
13. pt. reports salty/metallic taste, CSF leakage out of ear or nose, racoon's eyes,
