test one nostril at a time with a nonnoxious smell

17

CN I- any other info

Good to know if someone can smell- fire, chemicals

18

CN II- name

Optic

19

CN II- motor/ sensory/ auto?

sensory

20

CN II- how to test?

~the Snellen chart
~test peripheral vision
~corneal light reflexion test

21

CN II-the Snellen chart

~the eye exam to test how well you can read far away
~20/20 vision
~See if they can read

22

CN II- Test peripheral vision

test to see if you can see the normal visual field (average- 90 to the side, 60 up, 70 down)

23

CN II- Cornel light reflexion test

~see if there is a shape difference of the eye
~shine a light in the eye and you can see the reflection of light in the pupil

24

CN III- name

Oculomotor

25

CN III- motor/ sensory/ auto?

Motor, autonomic

26

CN III- how to test?

~Pupillary light reflex
~Convergence/ divergence testing

27

CN III- Pupillary light reflex

direct/indirect when blocking the other eye, the direct stimulation will have more constriction than the other one

28

CN III- Convergence/ divergence testing

looking far, near, you will dilate/ constrict

29

CN III- other info

~don’t have to know which movements go with which CN for eyes
~Ptosis- can’t open the eye lids
