hearing loss

Question 1

what are the types of hearing loss

Answer 1

sensorineural ,conductive and mixed hearing loss

Question 2

sensorineural hearing loss entails

Answer 2

this type of hearing loss occurs when the inner ear or the actual hearing nerve itself becomes damaged. typically occurs when some of the hair cells of the cochlea are damaged.

the most common type of hearing loss is

Answer 3

sensorineural hearing loss

Question 4

sensorineural hearing loss can be treated easily via medical or surgical means. t/f

Answer 4

F

Question 5

Causes of sensorineural hearing loss include

Answer 5

aging, exposure to loud noise, injury, disease, certain drugs or an inherited condition.

Question 6

A patient who has sudden sensorineural hearing loss should be advised to wait for about a month or two to see if it would resolve before seeing the doctor .T/F

Answer 6

F…A delay in treating the condition will most likely decrease the chances of improvement with medications

Question 7

conductive hearing loss entails

Answer 7

occurs in the outer or middle ear whereby sounds are not able to carry all the way through to the inner ear

Question 8

causes of conductive hearing loss include

Answer 8

sound may be blocked by earwax or by a foreign object located in the ear canal, the middle ear space may be impacted with fluid, infection or a bone abnormality ,otosclerosis, cholesteatoma, neoplasms of the middle ear or the ear drum may have been injured.

Question 9

conductive hearing loss is most common in children who may have recurrent ear infections or who insert foreign objects into their ear canal. t/f

Answer 9

T

Question 10

Mixed hearing loss occurs when

Answer 10

the patient has a combination of both sensorineural and conductive hearing loss.

Question 11

hearing loss is said to occur when

Answer 11

Any part of the ear or auditory system is not working in the usual way

Question 12

the outer is made up of

Answer 12

the pinna, the ear canal, the tympanic membrane

Question 13

the middle ear is made up of

Answer 13

the eardrum, the three ossicles

Question 14

the inner ear is made up of

Answer 14

the cochlea, the semicircular canals, the nerves that go to the brain

Question 15

auditory neuropathy spectrum disorder entails

Answer 15

hearing loss that occurs when sound enters the ear normally but as a result of damage to the inner ear or the auditory nerve, sound is not organised in a manner that can be interpreted by the brain.

Question 16

a person with a mild hearing loss may hear

Answer 16

some speech sounds but soft sounds are hard to hear

Question 17

a person with a moderate hearing loss may hear

Answer 17

almost no speech when another person is talking at a normal level

Question 18

a person with a severe hearing loss may hear

Answer 18

no speech when a person is talking at a normal level but may hear only some loud sounds

Question 19

a person with a profound hearing loss

Answer 19

will not hear any speech but only hear very loud sounds

Question 20

hearing loss may be described as

Answer 20

unilateral or bilateral
symmetrical or asymmetrical
progressive or sudden
fluctuating or stable
congenital or acquired

Question 21

hearing loss is diagnosed when

Answer 21

hearing test finds that a person is unable to hear 25 decibels in at least one ear.

Question 22

categorize hearing loss

Answer 22

mild(25-40), moderate(41-55dB), moderate-severe(56-70dB), severe(71-90dB) Or profound(>90dB)

Question 23

a progressive loss of ability to hear high frequencies with aging is known as

Answer 23

presbycusis

Question 24

examples of syndromic deafness

Answer 24

N- Neurofibromatosis type 2
A- Alport’s syndrome
U- Usher syndrome
S -Stickler syndrome
E- Waardenburg syndrome
A

Question 25

fetal alcohol spectrum disorders are reported to cause hearing loss in up to 64% of infants born to alcoholic mothers. T/F

Answer 25

T

Question 26

Examples of ototoxic medications

Answer 26

loop diuretics like furosemide, NSAIDS, aminoglycosides, platinum based chemotherapeutics like cisplatin and carboplatin.

Question 27

how long does it take the voice to be affected in sensorineural hearing loss

Answer 27

an average of 2-3 months

Question 28

webers test interpretations

Answer 28

A patient with a unilateral conductive hearing loss would hear the tuning fork loudest in the affected ear. This is because the ear with the conductive hearing loss is only receiving input from the bone conduction and no air conduction, and the sound is perceived as louder in that ear. This finding is due to the conduction problem of the middle ear (incus, malleus, stapes, and external auditory meatus) which masks the ambient noise of the room, while the well-functioning inner ear (cochlea with its basilar membrane) picks the sound up via the bones of the skull, causing it to be perceived as a louder sound in the affected ear.Sensorineural hearing loss will cause the sound to be heard best in the normal ear.

Question 29

a rinne’s positive test indicates

Answer 29

air conduction is better than bone conduction in that ear

Question 30

in what conditions would rinne’s test be positive

Answer 30

normal hearing
sensorineural hearing loss such that air conduction is better than bone conduction

Question 31

in what condition would rinne’s test be negative

Answer 31

conductive hearing loss
