Flashcards in Test One Deck (30):
1
If you see a skull defect what should you do and why
Mark defects, a breach rhythm will appear near defects
2
Contrecoup
Opposite side from injury
3
Coup
Side of impact
4
Williams Paradox
Following a severe head injury, the EEG returns to normal, but neurological and psychological abnormalities persist
5
closed head injury
skull fracture but the covering of the brain is not in tact
6
open head injury
skull fracture that exposes brain or meninges
7
otorrhea
drainage of CSF from ears
8
rhinorrhea
drainage of CSF from nose
9
why do head injuries cause loss of concussions
Due to concussion from blow to the head when recticular formation is damaged
10
tentorial herniation
Tentorium separates from the cerebral hemispheres of brain stem and cerebellum
11
why is intercranial pressure considered extremely crucial
prevents herniation, reduce pressure
12
extended nocturnal sleep recordings may be helpful in predicting whether the pt in post-traumatic coma will recover. Explain the favorable and unfavorable sleep stages for this type patient
stuck in one stage of sleep- worse
coma - bad
13
spikes occur more often in children than adults after a head injury
TRUE
14
explain the difference in an adult skull compared to a child's
adult- limited resilience beyond which it splinters
children- localized blow produces a depression without splintering
15
with rhinorrhea and otorrhea what can enter the skull? what can this possibly cause?
air, pathogens, viruses
causes infections, meningitis
16
epidural hematoma can cause bleeding, where?
above the dura
17
an acute epidural is composed of what type of blood
arterial
18
acute epidural a medical emergency?
YES
19
what vessel probably ruptured?
middle meningial artery
20
EEG changes with epidural hematoma show what?
focal slowing and attenuation of amplitude over the hematoma
21
a subacute epidural hematoma is composed of what kind of blood?
veneous
22
A subdural hematoma is bleed ___ the ___
under, dura
23
subdural hematoma is composed of what kind of blood?
venous
24
a subdural hematoma may behave clinically like a ____
tumor
25
subdural hematoma may be chronic. these are often seen in what kind of pts?
alcoholics, elderly, epileptics (people who fall)
26
Bilateral subdural hematoma may be seen in what kind of pts?
infants
27
EEG changes in subdural hematomas in adults will show what?
delta focus and voltage attenuation
children? more severe, more early detected than in adults
infants? bilateral abnormalities
28
A subarachnoid hemorrhage is bleeding into what space?
subarachnoid space
29
the eeg changes with subarachnoid hemorrhage are?
diffuse changes including disorganization, distortion of the posterior alpha activity and excessive slow activity
