CRANIAL NERVE ASSESSMENT

A. Cranial Nerve I (Olfactory Nerve)

To test the adequacy of function of the olfactory nerve: 1. The client is asked to close his eyes and occlude one nares. 2.

The examiner places aromatic and easily distinguishable substance close to the client’s nose.

(E.g. Coffee).

3. Ask the client to identify the odor

*** Each side is tested separately, ideally with two different substances.

1. Test the functioning of Cranial Nerve that innervates the facial structures.

Normal Finding: The client is able to identify an odor on each side of the nose.

2

B. Cranial Nerve II (Optic Nerve)

Testing for visual acuity and peripheral vision assesses the optic nerve.

Visual Acuity is tested using a Snellen chart for those who are illiterate and unfamiliar with the western alphabet, the E chart, in which the letter E faces in different directions maybe used. The chart has a standardized number at the end of each line of letter; this number indicates the degree of visual acuity when measured at a distance of 20 feet.

The numerator 20 is the distance in feet between the chart and the client or the standard testing distance. The denominator 20 is the distance from which the client eye can read the lettering, which correspond to the number at the end of each letter line; … therefore the larger the denominator the poorer the vision.

Measurement of 20/20 vision  is an indication of normal eye refraction and optic pathway; while measurement of less than 20/20 vision is an indication of either refraction error or some optic disorder.

3

In testing visual acuity you may refer to the following:

1.

The room used for his test should be well lighted.

2. A person who wears corrective lenses should be tested with and without them to check for the adequacy of correction. 3. Only one eye should be tested at a time; the other eye should be covered by an opaque card or eye cover, not with client’s fingers. 4. Make the client read the chart by pointing at a letter randomly at each line; maybe started from largest to smallest or vice versa. 5. A person who can read the largest letter on the chart (20/20) should be checked if they can perceive hand movement about 12 inches from their eyes, or if they can perceive the light of the penlight directed to their eyes.

Peripheral Vision or Visual Field The assessment of visual acuity is indicative of the functioning of the macular area, the area of central vision. However it does not test the sensitivity of the other areas of the retina, which perceive the more peripheral stimuli. The Visual field confrontation test provides a rather gross measurement of peripheral vision.

The performance of this test assumes that the examiner has normal visual fields, since the client visual field is to be compared with the examiners.

4

The following steps in conducting the test:

1. The examiner and the client sit or stand opposite each other, with the eyes at the same horizontal level with a distance of 1.5-2 feet apart. 2. The client covers the eye with opaque card, and the examiner covers the eye that is opposite to the client’s covered eye.

3.

Instruct the client to stare directly at the examiner’s eye, while the examiner stares at the client’s open eye. Neither looks out at the object approaching from the periphery.

4. The examiner hold an object such as pencil or penlight, in his hand and gradually moves if in from the periphery of both direction horizontally and from above and below. 5. Normally the clients should see the object at the same time the examiner sees it. The normal visual field is 180 degree.

C.

CRANIAL NERVE III, IV, AND VI (Oculomotor, Trochlear, Abducens)

All the 3 Cranial nerve are tested at the same time by assessing the Extra Ocular Movement (EOM) or the six cardinal position of gaze.

Following steps given;

1.

Stand directly in front of the clients and hold a finger or a penlight about 1ft from the client’s eyes.

5

2. Instruct the client to follow the direction of the object held by the examiner by eye movement only; that is without moving the neck. 3. The nurse moves the object in a clockwise direction hexagonally. 4. Instruct the client to fix his gaze momentarily on the extreme position in each of the six cardinal gaze.

5.

The examiner should watch for jerky movement of the eye (nystagmus).

6. Normally the clients can hold position and there should be no nystagmus.

D. Cranial Nerve V (Trigeminal) This cranial nerve functions both sensory and motor.

Sensory Function; •

Ask the client to close eyes.

•

Run cotton wisp over the fore head, cheek and jaw on both side of the face.

•

Ask the client if he/she feel it, and where she feels it.

•

Check for corneal reflex using cotton wisp.

•

The normal response is blinking.

Motor Function

•

Ask the client to chew or clench the jaw.

•

The client should be able to clench with strengths and force.

6

E.

Cranial Nerve VII (Facial) This cranial nerve function both sensory and motor.

Sensory Function (This nerve innervates the anterior 2/3 of the tongue)

•

Place sweet, sour, salty or bitter substances near the tip of the tongue.

•

Normally, the client can identify the taste.

Motor Function •

Ask the client to smile, frown, raise eye brow, close lids, whistle, or puff the cheeks.

Normal Finding:

•

Shape maybe oval or rounded.

•

Face is symmetrical

•

No involuntary muscle movements

•

Can move facial muscles at will

F.

Cranial Nerve VIII (Vestibulocochlear Nerve)

Examination of the cranial nerve VIII involves testing for hearing acuity and balance.

7

Hearing Acuity

A. Voice test 1. The examiner stands 2ft. On the sides of the ear to be tested. 2. Instruct the client to occlude the ear canal of the other ear.

3.

The examiner then covers the mouth and using a soft-spoken voice whisper nonsequential number (e.g. 3, 5, and 7) for the client to repeat.

4. Normally the client will be able to hear and repeat the number. 5. Repeat the procedure on the other ear.

B. Watch Test 1. Ask the client to close the eyes.

2.

Place a mechanical watch 1-2 inches away the client’s ear.

3. Ask the client if he hears anything. 4. If the client says yes, the examiner should validate by asking at “What are you hearing? On which sides?” 5. Repeat the procedure on the other ear 6. Normally the client can identify the sound and on which side was heard.

Tuning for test

8

This test is useful in determining whether the client has a conductive hearing loss (problem of external or middle ear) or a perceptive hearing loss (sensorineural). There are 2 types of tuning for test being conducted.

1.

Weber’s test – assesses bone conduction, this is a test of sound lateralization; vibrating tuning fork is placed on the middle of the forehead or top of the skull.

Normal: hear sounds equally in both ears (No lateralization of sounds) Conduction loss: a sound lateralizes to defective ear (Heard louder on defective ear) as few extraneous sounds are carried through the external and middle ear. Sensorineural loss – Sounds lateralize on better ear.

2.

Rinne test – compares bone conduction with air conduction a. vibrating tuning fork placed on the mastoid process, b. Instruct client to inform the examiner when he no longer hears the tuning fork sounding. c. Position the tuning fork in front of the client’s ear canal when he no longer hears it.

Normal: sounds should be heard when tuning fork is placed in front of the ear anal as air conduction < bone conduction by 2:1 (positive Rinne test) Conduction loss: sound is heard longer by one bone conduction than by air conduction. Sensorineural loss: Sound is heard longer by air conduction than by bone conduction.

9

G. Cranial Nerve IX and X (Glossopharryngeal and Vagus Nerve) 1. Sensory Function: *Mediate taste on the posterior one third of the tongue. *Technically difficult to test. 2. Motor function: •

Depress the tongue with a tongue blade and note pharyngeal

movement as the person says “ahhhh” or yawns. •

The uvula and the soft palate should rise in the midline and the

tonsillar pillar should move medially. •

Touch the posterior pharyngeal wall with a tongue blade and note

the gag reflex. •

Note the voice of the client ( should be smooth and not strained)

H. Cranial Nerve XI (Spinal Accessory Nerve) •

Examine the stetamoid and the trapezius muscle for equal size. Check

equal strength by asking the person to rotate the head forcibly against resistance applied to the side of the chain. •

I.

Ask the client to shrug the shoulders against resistance.

Cranial Nerve XII (Hypoglossal Nerve) •

Inspect the tongue (there should be no tremors).

•

Note the forward thrust in the midlines as the client protrudes the

tongue.

10

•

Ask the person to say “light, tight, dynamite”, the sounds lingual speech

(letters l, t, d) is clear.

TEST FOR CEREBELLAR FUNCTION

Balance test:

A. Tandem walking •

Ask the person to walk a straight line in a heel-to-toe fashion.

Tandem walking decreases the base of support and accentuates problem with coordination. Normally, the person can walk straight and stay balanced. Inability to tandem walk may indicate upper motor neuron lesion such as multiple sclerosis.

B. Romberg test •

Ask the person to stand up with feet together and arms at all side.

•

Ask the client to close the eyes and to hold the position for about 20

seconds.

•

Normally, a person can maintain posture and balance even with the

visual orienting information blocked, although slight swaying may occur. Positive Romberg sign (loss of balance that occurs when closing the eyes) occurs with cerebellar ataxia, loss of proprioception and loss of vestibular function. Coordination tests:

11

A.

Rapid alternating movements (RAM) •

Ask the person to pat the knees with both hands, patting alternately

with the dorsum and palmar surfaces of the hands.

•

Start slowly then ask the client to do it faster.

•

Ask the person to touch the thumb to each finger on the same hand,

starting with the index finger then reverse direction.

B.

Finger-to- Finger test •

With person’s eyes open, ask the client to touch your finger then touch

his own nose repeatedly. After several times, move your finger to a different spot.

C.

Finger-to-Nose test •

Ask the client to touch the tip of his nose with his index finger,

alternating hands for several times.

SENSORY FUNCTION TESTS

A. Stereognosis

– test the persons ability to recognized objects by feeling their

forms, sizes and weights, •

Ask the clients to close his eyes and identify an object that is placed in

his hand.

12

•

Test a different object in each hand.

* Normally, a person will explore the object with the fingers and correctly name it. Testing the left hand assesses right parietal lobe functioning. Astereognosis occurs in sensory cortex lesions.

B.

Graphestesia – Ability to read a number by having it traced on the skin.

•

With the client’s eyes closed, use a blunt instruction to trace a number or a letter on the palm.

•

Ask the person to tell you what the number or letter is.
