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

30

Describe typical accident neurosis. What is post traumatic syndrome?

Complaints of headaches, impairment of memories, unable to work, irritability, can't deal with noise
