Examination Questions and Correct
Answers/ Latest Update / Already Graded
Acquired Brain Injury
Ans: Injury to the brain that's not hereditary, congenital,
degenerative, or induced by birth trauma.
Coup-Contrecoup Injury
Ans: When the head/brain moves forward (linear acceleration)
and then strikes an object with rapid linear acceleration of the
brain, resulting in frontal lobe focal lesions (this is coup). Then
the rebound where the brain/head moves backwards striking an
object causing occipital lobe focal lesions (contrecoup).
Closed Injuries
Ans: Can cause brain lacerations and contusions, or
intracerebral hemorrhage within the brain causing fatal injuries.
Examples of closed injuries include "coup -contrecoup injury" or
"diffuse axonal injury."
Hypoxia
Ans: Low levels of oxygen

Anoxia
Ans: An absence of oxygen
Hydrocephalus
Ans: Buildup of fluid in the cavities (ventricles) deep within the
brain; Pressure of fluid is damaging.
CSF (cerebral spinal fluid)
Incidence
Ans: Rate or range of occurrences
Prevalence
Ans: Refers to the number of people with a given condition at a

Normal structural imaging; LOC= 0-30 minutes; AOC= from a moment
up to 24 hours; PTA= 0-1 day; GCS= 13-15.zz
Moderate TBI
Ans: Will be marked by unconsciousness for any period of time
up to 24 hours, will have neurological signs of brain trauma,
including skull fractures with contusion or bleeding, and may
have focal findings on an EEG/CT scan.
Normal or abnormal structural imaging; LOC > 30 minutes and <
24 hours; AOC > 24 hour severity based on other criteria; PTA >
1 and < 7 days; GCS= 9-12.
Severe TBI
Ans: Marked by a period of loss of consciousness of 24 hours or
greater.
Normal or abnormal structural imaging; LOC > 24 hours; PTA >
7 days; GCS= 3-8.
