Deck 17: Hearing and Hearing Disorders

Question 1

When working with special populations such as medically fragile patients and patients with mental retardation,special techniques are needed to measure their hearing.These techniques often include

A)Speech detection threshold measures
B)Air conduction pure tone testing
C)Bone conduction testing
D)Tympanometry

Answer 1

D

Question 2

John has a sensorineural hearing loss and Paul has a conductive hearing loss.

A)John's speech discrimination skills are probably better than Paul's speech discrimination abilities.
B)Paul's speech discrimination skills are probably better than John's speech discrimination abilities.
C)John and Paul probably display similar speech discrimination abilities.
D)John's speech discrimination skills will be better for the left ear and Paul's speech discrimination will probably be better for the right ear.

Answer 2

B

Question 3

Scott's test results suggest a

A)Conductive hearing loss
B)Sensorineural hearing loss
C)Presbycusis
D)Brainstem tumor

Answer 3

A

Question 4

Audiometers emit pure tones used for quantitative measurement of hearing thresholds.

Question 5

Tests by air conduction are accomplished by placing earphones over the outer ears.Pure tone sound waves are carried through the outer ear and middle ear,converted to electrochemical energy in the inner ear and transmitted to the brain for processing by the auditory nerve.Four-year old Scott's air conduction test results for the right ear show thresholds of 40 dB HL @ 500 Hz,35 dB @ 1000Hz,and 35 dB @200 Hz.What may have happened along the air conduction pathway to produce these results?

A)Prenatal history of maternal rubella
B)Meniere's disease
C)A poorly functioning auditory tube
D)None of the above

Question 6

0 dB HL refers to the absence of sound.

Question 7

Habilitation services are offered to children and adults who lose their hearing after speech and language have been developed,whereas rehabilitation services are offered to children who develop hearing loss before the development of speech and language.

Question 8

In general,the greater the amount of sensorineural loss,the poorer the speech discrimination abilities.

Question 9

Hospital-based audiologists may not only conduct universal infant hearing screening programs,they may also provide the following clinical services

A)Cerumen management
B)Intraoperative monitoring
C)Counseling services to patients with hearing loss and their families
D)All of the above
E)A and C only

Question 10

Many hospitals have a newborn hearing screening program.The screening methods most often used by such programs include

A)ABR and OAE
B)OAE and electrocochleography
C)Air and bone conduction testing
D)Tympanometry

Question 11

Sound intensity is perceived as loudness.Sound frequency is perceived as pitch.

Question 12

Interpret this audiogram

A)Normal hearing
B)Slight conductive loss
C)Severe mixed loss
D)Moderate sensorineural loss

Question 13

Auditory localization is the ability to identify the direction of the sound source.

Question 14

Four-year old Allison's hearing loss is congenital.Five-year old Mark's hearing loss occurred at age 4 ½ after a bout with rubella.

A)Allison is less likely than Mark to experience language delay.
B)Allison is more likely than Mark to experience language delay.
C)The risk for language delay is similar for both children.
D)None of the above

Question 15

Otololaryngologists prescribe and dispense hearing aids.

Question 16

One clinical service provided by audiologists is cerumen management.

Question 17

Scott's bone conduction and air conduction test results revealed a significant air-bone gap for the right ear.What may be producing this air-bone gap?

A)Overgrowth of the mastoid bone
B)Presence of middle ear disease
C)Presence of sensorineural loss
D)Lesion of the auditory nerve

Question 18

In general,sensorineural hearing losses are irreversible,whereas conductive hearing losses are reversible.

Question 19

Laurie has normal hearing; however,her air conduction test results are,on average,5 dB higher than her bone conduction test results in both ears.What accounts for these results?

A)Laurie has an undiagnosed sensorineural hearing loss
B)At time of testing Laurie was experiencing a mild upper respiratory infection causing slight accumulation of fluid in the middle ear.
C)In air conduction testing,the sound bypassed the outer and middle ear measuring only the sensitivity of the inner ear
D)In bone conduction testing,the sound bypassed the outer and middle ear measuring only the sensitivity of the inner ear
E)B and D

Question 20

Full-term babies and premature babies present with the same degree of risk for developing hearing loss.

Question 21

Patients with sensorineural hearing loss are considered better candidates than patients with conductive hearing loss for hearing aids.
