Q

how do you inspect pupillary reaction to light

A

shine a bright light obliquely into one pupil
normal reaction = light will cause both pupils to contstrict

21
Q

How do I check eye alignment?

A

Shine light straight onto pt’s eye from 2 ft away. Light should appear in the center of their pupil.

Abnormal = esotropia

22
Q

describe extra ocular muscle examination technique. what CN is this?

A

ask pt to follow your finger in all 6 directions of gaze
CN 3, 4, 6.

23
Q

which eye muscles go with which cranial nerve

A

LR6 SO4 R3

lateral rectus = 6 (lateral movement)
superior oblique = 4 (down and out)
rest = 3 (everything else)

24
Q

What is proptosis? what indicates proptosis?

A

Protrusion of eyeball. a positive lid lag assessment indicates proptosis (when the eyelid does not move with the eye)

25
Q

What is a Snellen chart?

A

Visual acuity chart with the letters. Handheld is 14 inches away, normal is 20 ft away.

26
Q

Why is visual acuity written with 2 numbers?

A

First # is how far the chart is
Second # is how far a normal eye can read that line.

20/30 means chart is 20 ft away. A normal eye can read the letters from 30 ft away still.

the larger the second number the worse the vision

Minimum VA for DL is 20/40.

27
Q

What are the abnormalities for Visual acuity called?

A

Myopia = impaired far vision
Hyperopia = impaired near vision
Presbyopia = loss of focus (old eyes)
Legal blindness = 20/200 or worse.

28
Q

How do I document each eye’s Visual acuity?

A

OD = right
OS = left
OU = both

29
Q

binocular vs monocular vision

A

binocular = the overlap of visual fields when using two eyes
monocular = he lateral vision that one eye sees but the other cannot

30
Q

What are some visual field defects?

A

Horizontal defect (loss of one eye’s lower half)
Blind R eye
Bitemporal hemianopsia (loss of lateral visual field, optic chiasm lesion)
L homonymous hemianopsia (loss of both left visual fields, R optic tract lesion)
Homonymous L superior quadrantic defect

Honestly its easier just to look at slide 37 and just draw this out.

31
Q

What is refraction adjustment for?

A

Hyperopia is corrected via clockwise rotation, ^ focal power, focal point towards yourself.

Myopia is corrected via counterclockwise rotation, decrease focal power, focal point away from yourself.

32
Q

How do I adjust aperture?

A

Dilated eyes need big apertures.
Normal eyes need small apertures.

33
Q

What kind of glow should I see in a fundoscopic exam?

A

Red/orange reflex.

Lack of red/orange reflex suggests cataracts, corneal scarring, vitreous hemorrhage, or retinoblastoma.

34
Q

What does the optic disk look like in a fundoscopic exam?

A

Round yellowish-orange circle. Follow blood vessels towards nose if not visible.

35
Q

What can systemic HTN lead to in the retina?

A

Focal narrowing of retinal arteries
AV nicking (vein disappears under artery)
Increased light reflex of retinal arteries (copper wire appearance)

36
Q

What does uncontrolled DM appear as in the retina?

A

retinopathy which appears as cotton wool spots and retinal hemmorhages.

37
Q

label the pink spots

A

k

38
Q

What are some ear abnormalities?

A

Otitis media (purulent fluid in middle ear)
Retraction of TM (problems with the eustachian tube)

39
Q

what is the treatment for recurrent otitis media

A

tympanostomy tubes

40
Q

What are te tests for auditory acuity and what CN do they relate to

A

whisper test
Weber test
Rinne Test
CN 8

41
Q

describe normal and abnormal hearing tests from the weber test

A

normal: hear ringing in both ears
abnormal (conductive hearing loss) - sound is lateralized to defective ear
abnormal (sensorineural) - sound is lateralized to the good ear

42
Q

what does the rinne test compare
what are the possible normal/abnormal outcomes

A

air v bone conduction.
normal hearing and sensorineural hearing loss = AC>BC
conductive hearing loss = BC>AC

43
Q

What are the two types of hearing loss?

A

Conductive (air - results from problems in external or middle ear, preventing sound waves to reach inner ear)
Sensorineural (bone - results in problems from inner ear preventing sound waves from being properly processed)

44
Q

What is the whisper test?

A

Whisper at least a two syllable word behind a patient, have them cover one ear.

45
Q

What does the Weber test test for?

A

Lateralization of bone conduction. Should hear equally.

Requires a 512 Hz tuning fork on top of head.

46
Q

What does the Rinne test test for?

A

Comparing air to bone conduction.

512 Hz tuning fork to mastoid. Once pt can’t hear, bring the fork near their ear.

Normal is hearing the vibration near the air canal even after bone conduction is gone.

47
Q

What are stenson’s ducts?

A

Each parotid duct that opens onto the buccal mucosa.

48
Q

what are the CN for the pharynx

A

CN IX, X

49
Q

tonsils are characterized by using what size chart

A

using a 1-4+ scale with 4+ being touching/kissing tonsils.

50
Q

How do I know if I’m on a lymph node?

A

Lymph nodes should be rollable in 2 directions.
Up, down, side to side.

51
Q
A
52
Q

What am I looking for in anterior neck inspections?

A

Upward movement of thyroid and contour/symmetry when swallowing.
