35
Q

TBI can be described as penetrating or closed head injury but also as what other two things

A

focal or diffuse

36
Q

what is a focal TBI injiry

A

injury confined to a specific area of the brain causing localized
damage

37
Q

what is a diffuse TBI injury

A

injury is characterized by

damage throughout the brain

38
Q

true or false: for penetrating objects, the clinacal outcome is usually good

A

true w

39
Q

if there is a penetrated object in the brain, do they always remove it>

A

no may or may not remove it

40
Q

what is a hematoma

A

Collection of blood outside of blood vessels.
Bleeding can occur outside the brain (subdural) or
within the brain tissue itself (intracerebral)

41
Q

Bleeding that occurs outside the brain (is called what

A

subdural

42
Q

or

bleeding that occurs within the brain tissue itself is called what

A

intracerebral

43
Q

what is hemmorage

A

bleeding directly into the brain tisse

44
Q

diffuse axonal injury results from what

A

Results from a tearing of nerve bundles and/or

stretching of blood vessels (from contre coup)

45
Q

what are contusions of the brain

A

Bruises that cause swelling and bleeding resulting in

tissue damage

46
Q

what are the 4 causes of TBI (bleeding etc)

A

hematoma
hemmoraging
diffuse axonal injury
contusions

47
Q

what happens to the nerve fibers in a TBI and what does that result in

A

Nerve fibers within specific areas of the brain are severed

Ø Nerve fibers are stretched which results in inefficient and slowed functioning

48
Q

true or false: coup contre coup can only happen is your head makes contact with the stationary object

A

false, can only occur if the moving object contacts with the head

49
Q

what is the coup part of the contre coup injury

A

brain injury at the point of impact (primary impact)

50
