A

Use Tumbling E Chart

21
Q

Place tuning fork 1st on mastoid process and then in front of the ear. Time each area
Normal finding: Air conduction (AC) last longer than bone conduction (BC)

25
Q

Conductive hearing loss (outer ear/middle ear)

A

Any obstruction (or conduction) of the sound waves will cause conductive hearing loss

  • Blockage of the outer ear (ceruminosis, otitis externa)
  • Fluid inside of the middle ear (otitis media, serous otitis media)
26
Q

Sensorineural hearing loss (Inner ear)

A

Damage (aging) of the cochlea/vestibule (Presbycusis, Meneres disease) and/or to the nerve pathways (CN VIII or acoustice nerve) causes sensorineural hearing loss
* Ototoxic drugs (oral aminoglycosides, erythromycin, tetracyclines, high dose aspirin, sildenafil)
*stroke
Sensorineural hearing loss = permanent hearing loss

27
Q

Weber and rinne tests results are opposite of each other

A

Sensorineural hearing loss = AC>BC

Conductive Hearing loss = BC>AC

28
Q

Describe pinguecula

A

Raised yellow-white small round growth in the bulbar conjunctiva (skin covering eyeball) next to cornea
Located on nasal/temporal side of eye
Caused by: chronic sun exposure

29
Q

Describe pterygium

Yellow triangular (wedged-shaped) thickening of conjunctiva that extends across the cornea on the nasal side.
Results from chronic sun exposure
Can be inflammed at times
Persons may c/o foreign body sensation in eye

30
Q

Treatment of Pinguelcula and Pterygium

A

If inflammed: refer to ophthalmologist for script of weak steroid eye drops to use only during exacerbations
Artifical tears PRN
good quality sunglasses
remove surgically if they affect the cornea and vision

31
Q

Describe Chalazion

A

Chronic inflammation of the meibomian gland (special sweat gland) of the eyelids
May resolve in 2-8 weeks
S/S: gradual onset of a small superficial nodule on upper eyelid that feels like a bead (person describes it as painless) Can enlarge overtime and press on cornea and cause blurred vision
TX: I&D, surgical removal, intrachalazion corticosteriod injections by ophthalmologist

32
Q

What are some autoimmune disorders that cause eye problems?

A
  1. Rheumatoid Arthritis
  2. Lupus
  3. Ankylosing Spondylitis
33
Q

Age-Related macular degeneration

A

Gradual damage to the pigment of the macula (area of central vision) that results in 2 types:

  1. Atrophic (Dry form)
  2. Exudative (wet form)
34
Q

S/S of age-related macular degeneration and treatment

A

Gradual or sudden painless loss of central vision
Subjective findings: persons reports that straight lines (doors, windows) that appear distored or curved
TX: refer to ophthalmologist

35
Q

Allergic Rhinitis

A

Inflammatory change of the nasal mucosa d/t alleries.
Increased risk of sinusitis
May have intermittent, seasonal or daily symptoms
Atopic Family HX (asthma, eczema), Dust mites (daily symptoms), mold/grass (summer), ragweed pollen (fall)

36
Q

S/S of allergic rhinitis

A

Subjective findings: person c/o chronic or seasonal nasal congestion with clear mucus rhinorrhea or post nasal drip, nasal itch, frequent sneezing
Objective findings: Blue tinged/pale boggy nasal turbinates, clear mucus, posterior pharynx = thick mucus may be clear, white, yellow or green (need to rule out sinusitis), undereye circles (venodilation)
In children: transverse nasal crease from frequent rubbing (allergic salute), posterior pharynx = cobblestoning

37
Q

Treatment for allergic rhinitis

A
  1. nasal steriod sprays daily (OTC): Fluticasone (Flonase), Trimcinolone (Nasacort allergy)
  2. if partial relief with OTC: Topical antihistamine nasal spray: Azelastine (Astelin)
  3. If no relief with OTC: combination product: Azelastine and Fluticasone nasal spray

  5. Oral antihistamines: second generation antihistamine (OTC): Cetirizine (zertec), Loratadine (Claritin), diphenhydramine (Benadryl)

Eliminate environmental allergens
- Avoid using ceiling fans, no stuffed animals or pets, use HEPA filter for air conditioners, room filters

39
Q

What are the criteria used to diagnose strep throat?

A

4 components of the Centor Criteria are: fever, tonsillar exudate, anterior cervical lymphadenopathy, and absence of cough

40

41
Q

Describe Leukoplakia

A

White to light gray patch that appears on tongue, floor of mouth or inside of cheek
Rule out oral cancer

42
Q

Aging in the eye

A
  1. Cornea: thicker and less curved, decreased sensitivity to touch, formation of a gray ring at the edge of cornea (arcus senilis)
  2. Anterior Chamber: decrease in size and volume caused by thickening of lens. Occasional exerts pressure on schlemm canal and may lead to IOP and glaucoma
43
Q

Aging in the eye

A
  1. Lens: increase in thickness and opacity (yellowing), loss of elasticity. Decrease in refraction with increase light scattering, decrease color vision (blue/green), delayed dark adaptations, cataracts
  2. Ciliary mm: reduction in pupil diameter, atrophy of radial dilation mm. Persistent constriction (senile miosis), decrease critical flicker frequency
44
Q

Aging in the eye

A
  1. Retina: reduction in # of rods at periphery, loss of rods and associated nerve cells. Increase in minimum amt of light necessary to see an object.
  2. Macula: atrophy. Loss of vision
  3. Vitreous: Liquefaction of vitreous and decrease in gel volume. Risk for retinal detachment.
45
Q

Glaucoma

A

IOP > 12-20mmgh with death of retinal ganglion cells and optic nerve axons.
Resistance to aqueous humor outflow
Chronic IOP decreases peripheral vision and then central vision and blindness
Loss of vision from pressure on the optic nerve

46
Q

Glaucoma Treatment

A

Early detection and initiation of treatment to prevent optic neuropathy and visual impairment.
Pharmaceutical eyedrops to reduce secretion or increased absorption of aqueous humor
Surgery

47
Q

Color Blindness

A

Inherited trait
Generally an X-linked recessive trait
Most common: red/green

48
Q

What tests checks for color blindness?

A

Color plate test or Ishihara color test: Look at an image made of colored dots with a color # or shape in the middle. Different color plates can check for differerent types of color blindness
Anomaloscope test
Hue test
