Acquired Brain Injury ACTUAL
UPDATED QUESTIONS AND CORRECT
ANSWERS
what are the two types of ABI? - CORRECT ANSWERS✅✅- traumatic
- non-traumatic
What is a traumatic brain injury (TBI)? - CORRECT ANSWERS✅✅- external physical
force hard enough to cause movement of the brain
what is a closed TBI? vs open TBI? what are examples of each? - CORRECT
ANSWERS✅✅- closed: Without skull fracture (mild, concussions)
- ex: concussion, contusion, coup-Countercoup, diffuse axonal (shearing), Blast injury
- open :With skull fracture
- ex: penetration, blast injury
what can head injury with skull involvement involve? - CORRECT ANSWERS✅✅-
vascular injury (causes hemorrhage)
- skull fragments (causes compression)
- penetrating objects (causes direct damage to NS tissue and vasucaler structures)
what are examples of non-traumatic brain injuries? - CORRECT ANSWERS✅✅-
anoxic//hypoxic
- brain illness (encephalitis and meningitis)
- CVA
- brain tumors
- methods used to treat brain tumors
- toxic and metabolic injuries
- drug abuse
- hydrocephalous (too much CSF in brain)
, what is a contusion? what happens? where is it most common? - CORRECT
ANSWERS✅✅- brain tissue brusing
- small blood vessel leaks
- more serious than a concussion (involves structural damage)
- most common in frontal and temporal lobes)
what is coup-contrecoup? - CORRECT ANSWERS✅✅brain injury that occurs at the site of
trauma and the opposite side
- coup: side of impact
what is a diffuse axonal injury (DAI)? what does tearing of nerve tissue disrupt? where are
lesions found? what are examples of this injury? what are common sites? what is there high
risk for? - CORRECT ANSWERS✅✅- unmoving brain lags behind movement of skull =
tearing
- tearing of nerve tissue disrupts the brains regular communication and chemical processes
- Lesions found in the white matter of the brain
- Ex: Rotational injuries and Shaken Baby Syndrome
- Common sites: corpus collosum, brainstem, cerebellum, basal ganglia
- high risk for coma
what are the characteristics of a primary blast injury? - CORRECT ANSWERS✅✅- results
from the impact of the over-pressurization wave with body surfaces (high order explosives =
dynamite)
what are the characteristics of secondary blast injuries? - CORRECT ANSWERS✅✅results
from flying debris and bomb fragments
what are characteristics of tertiary blast injuries? - CORRECT ANSWERS✅✅results from
individuals being thrown by blast wind
what are characteristics of quaternary blast injuries? - CORRECT ANSWERS✅✅all
explosion related injury not due to all other blast injury categories
