Flashcards in The Brain/Neurological Assessment - Unit 3 Deck (24):
1

The Brain - basic building block is the ___.

Neuron.

2

A ___th of our brain is visual processing.

4th.

3

Brain - __% tissue, CSF ___%, Blood __%.

Tissue 80%
CSF 10%
Blood 10%

4

What do the meninges do?

Cover the skull/parts of brain

5

Glucose - what does it do in the brain?

It is brain food!

6

What is autoregulation in the brain?

It's when the brain changes the diameter of the vessels because it needs to.

7

How much CSF do we produce in an hour?

About 20 mL/hour.

8

Hyperventilation - what does it do?

Protects us - CO2 dilates vessels in brain, so hyperventilation gets rid of CO2.

9

LOC - most sensitive neuro test. T/F?

True!

10

What are parts of the neuro exam?

Mental status, cranial nerves, motor system, reflexes, sensory system, coordination, station and gait.

11

When testing for pain/stimulation, should we test centrally?

Yes!

12

Stereogenesis - what is it?

Can't understand what you're feeling without looking at it.

13

What's the Romberg test?

Close your eyes - if you can stand in one place and not move around, you're good!

14

Glasgow Coma Scale - Scoring - Eye Opening

Spontaneous - 4
To speech - 3
To pain - 2
None - 1

15

Glasgow Coma Scale - Scoring - Verbal Response

Oriented - 5
Confused conversation - 4
Words (inappropriate) - 3
Sounds (incomprehensible) - 2
None - 1

16

Glasgow Coma Scale - Scoring - Best Motor Response

Obey commands - 6
Localize pain - 5
Flexion - Normal - 4
Abnormal Flexion - 3
Extend - 2
None - 1

17

If the Glasgow scale is less than 5, what has to happen?

Organ procurement is called.

18

Hippus pupils - def

Constrict then dilate back. This could be caused by an increase in ICP.

19

Pinpoint pupils - what might cause this?

Opioid overdose.

20

GIANT pupils - what might cause this?

Atropine

21

Hemeneoisis - what is it?

Vision loss of half of field.

22

Conjugate gaze - def

eyes going in different directions.

23

Nystagmus - what is it?

eye jerking.

24

What are some diagnostics tests in the neuro world?

CT/CTA (Arteries - great for stroke patients.)
MRI, MRI - 3D
PET - lights up the bad areas
Cerebral angiograms - dye - can see the vessels.
Carotid Doppler.
Lumbar puncture - infection?
Brain flow study - brain dead? If it doesn't go up to the brain...oh boy!
