3. Oculomotor (motor)
4. Trochlear (motor)
5. Trigeminal (both)
6. Abducens (motor)
7. Facial (both)
8. Vestibulocochlear (sensory)
9. Glossopharyngeal (both)
10. Vagus (both)
11. Accessory (motor)
12. Hypoglossal (motor)
how to assess optic nerve (CN2) Using ophthalmoscope, examine ocular
fundus to
determine color, size, and shape of optic
disc
how to assess oculomotor nerve watch eye movement- upward, medial,
(CN3) downward,
up and in
check pupils for size, regularity, equality,
direct and
consensual light reaction, and
accommodation
,how to assess trochlear nerve watch eye movement- down and in
(CN4) check pupils for size, regularity, equality,
direct and
consensual light reaction, and
accommodation
how to assess abducens nerve have client look side to side
(CN6) check pupils for size, regularity, equality,
direct and
consensual light reaction, and
accommodation
how to assess facial nerve (CN7) Motor: corneal reflex (with client looking
forward,
bring cotton in from side and lightly touch
cornea-
not routinely tested); request to smile,
frown, close
eyes tightly, lift eyebrows, show teeth
Sensory: test taste by covering cotton in
solution
(not routinely tested)
how to assess vestibulocochlear ability to hear normal conversation and
(acoustic) nerve (CN8) whispered
voice test; may also use tuning fork
how to assess accessory nerve ask client to rotate head against
(CN11) resistance, ask
client to shrug shoulders against
resistance
, balance test observe as person walks 10-20 feet, turns,
and
returns to starting point; walk heel-to-toe
romberg test -ask client to stand with feet at comfortable
distance apart, arms at sides, and eyes
closed
-expected finding: client should be able to
stand
with minimal swaying for at least 5
seconds
+ swaying
- no swaying
Rapid Alternating Movements Assess coordination by asking person to
pat the
knees with both hands, lift up, turn hands
over and
pat knees with the backs of the hands.
Then ask
them to do it faster.
Normal Finding: Done with a equal turning
and
quick rhythmic pace
normal/abnormal findings for -normal: ID smell on each side of nose,
olfactory nerve dec smell
with age
-abnormal: asymmetry in sense of smell
(anosmia)
