Q

occurs in the inner ear where cochlea is - it destroys the hair
• The vibration goes to stapes but not further - there is no hair to carry it further
• Meds such a aspirin stun the hair, often with d/c use of aspirin hair will grow back.
• But with drugs such as diuretic and aminoglycoside hair might not grow back

Q
  • Is a hearing test
  • Its compares perception of sound
  • It transmitted through the mastoid bone
  • It is bone conduction
  • Then we bring to the front of ear
  • It is air conduction.

Q

Sound laterizes to better ear or unaffected ear Ear with nerve loss is unable to perceive sound
• sensorineural loss

A

Weber

20
Q

o Measures sensitivity of hearing to various frequencies
• patient signals when sound is heard
o Certain sounds the older adults can’t hear
o Such as high pitched sound

A

Audiometric procedure

21
Q

: involves neuroassessments
• Checks, gait
• Post pointing
• Balance

A

Vestibular

22
Q

o Warm and cold water introduced into ear
o Used to be done on pt who were brain dead
o Will test which way the eyes go
o This sign was to determine if pt was brain dead
o Not used anymore, today we do 3 ECG’s 8hr apart and 2 physician must be there to testify that ECG where flat

A

Caloric test

23
Q

o Typically done in pediatrician office
o Puffs air onto tympanic membrane
o Checks resilience of tympanic membrane
o Ability of ear drum to respond to changes in air pressure
o In pt who have otitis media and middle ear is filled with fluid we will not get the resilience, and tympanic membrane will not move

A

Pneumatoscopy

24
Q 
Maximize the communication skills of the person with hearing impairment 
• auditory training 
• speech reading 
• speech training 
• use of training aids, guide dogs
A

Aural rehab

25
Q

Listening. Skills so the person who is hearing impaired concentrates with speakers

A

Auditory training

26
Q

Known as lip reading

• goals of speech training are to conserve develop and prevent deterioration of current communication skills

A

Speech reading

27
Q

Impaction
• causing otalgia, sensation if fullness or pain
• with or without hearing loss

A

Cerumen impaction

28
Q

Irrigation
Suction
Instrumentation
• gentle suction irrigation helps remove impacted
• must flow behind the obstruction to move it first laterally and then out the canal
• lowest effective pressure

A

Cerumen impaction

29
Q

Warmed glycerin
Mineral oil
Half strength hydrogen peroxide
For 30 mins can soften

A

Cerumen impaction

30
Q

Check the external ear when swimming showering or washing •hair dryer external canal afterword with a hair dryer on low heat
• alcohol drops may be placed in external canal to act as astringent
• refrain any water sport activity 7-10

A

Nursing management external Otis

31
Q

Middle ear effusion
Involves fluid without active infection in middle ear
- seen after radiation therapy or barotrauma, plane descent or scuba diving

A

Serous otitis media

32
Q

Complain hearing loss, fullness In the ear, sensation of congestion, popping, crackling noises that occurs as the eustachisn tube attempts to open
• TM appears dull
• air bubbles viszuliazed in middle ear
•audiogram showed conductive hearing loss

A

Serious otitis media manifestation

33
Q

Myringotomy
Corticosteroids decease swelling
Valsalva

A

Management of serous otitis media

34
Q

Brief period of incapacitating vertigo that occurs when the position of the patients head is changed with respect to gravity, typically head back, effected ear down

A

Benign parxysmal positional vertigo

35
Q

▪ Diuretics: ethacrynic acid, furosemide (Lasix), acetazolamide
▪ Chemotherapeutic agents: cisplatin, nitrogen mustard
▪ Antimalarial agents: quinine, chloroquine
▪ Anti-inflammatory agents: salicylates (aspirin), indomethacin , and motrin
▪ Chemicals: alcohol, arsenic
▪ Aminoglycoside antibiotics: amikacin, gentamicin, kanamycin, netilmicin, neomycin, streptomycin, tobramycin
▪ Other antibiotics: erythromycin, minocycline, polymyxin B, vancomycin
▪ Metals: gold, mercury, lead

A

Ototoxic Drugs

36
Q

Unique hearing loss
o Typically found in women
o Begins after or during child bearing years
o Softening of stapes bone due to decrease of calcium
o Stapes becomes spongy and doesn’t transmit sound well
o Can be unilateral but in most cases bilateral
• need Stapedectomy

A

Otosclerois

37
Q
  • Concern for loss or movement of prosthesis
  • Eustachian tube maintains pressure
  • Avoid coughing or sneezing or blowing nose and yelling (for 1 week)
  • Anything that can increase or decrease pressure in Eustachian tube could knock into stapes.
  • No bending at waist
  • No valsalva
  • No lifting more than 5 lb (size of preme baby)
  • No flying
  • Move slowly
  • No showers.
  • Assess facial nerve
A

Stapesectomy

38
Q 
Put pt in nice dark room
• Pt must move slowly
• Be careful not to bump pt in bed
• Any kind of sudden movement is enough to put pt in a spin because of the swelling in the inner ear.
• vertigo 
• reduced hearing 
• temporary/ permanent facial paralysis
A

Stapedectomy post op complications

39
Q

Stand about 1 to 2 feet away from the ear to be tested.

A

gross auditory acuity

40
Q

is a progressive bilateral symmetrical age-related sensorineural hearing loss. The hearing loss is most marked at higher frequencies

A

Presbycusis

41
Q

Loose ear mold
Improperly made/worn
Worn out

A

Whistling sound of hearing aid

42
Q

Too much power required in aid, with inadequate sore ration between microphone and receiver

Open mold use inappropriately

A

Improper aid selection

43
Q 
Dead batteries 
Cerumen in ear 
Cerumen or other material in mold 
Wires or tubing disconnected from aid 
Aid turned off or volume too low 
Improper mode 
Improper aid for degree of loss
A

Inadequate amplification

44
Q

Improperly fitted mold
Ear skin or cartilage infection.
Middle ear infection
Ear tumor

A

Pain from mold

45
Q

• S/S:
o Dizziness
o N/V
o Drainage in ear
o Hollow reverberating sound
• Immediate treatment for ruptured tympanic membrane would be
• Preventing infection, since there is a direct route from the outside to the inner ear.
• Put sterile dressing on /so nothing can get in
• Do not pack ear
• Pt cant swim, shower until physician has cleared them

A

Ruptured tympanic membrane

46
Q

From otosclerosis or Otis media

Hears sound better in the affected ear

A

Conductive hearing loss

47
Q

Results from damage to cochlear or vestibulocochlear nerves hears the sound in the better hear ear

A

Sensorineural loss
