Part 2.3 Flashcards
Your client has an SRT of 45 dB, an MCL of 65 dB, and a UCL of 100 dB. Your DR is _____?
a) 20 dB
b) 35 dB
c) 55 dB
d) not enough information
c) 55 dB
SRT is bottom, UCL is top. MCL doesn’t have anything to do with it.
What type of hearing loss results in the person speaking in a louder than normal voice?
a) conductive
b) sensorineural
c) mixed
d) central
b) sensorineural
He speaks loudly because he can’t hear himself.
The type of hearing loss which results in a person speaking in a softer than normal speaking voice is called what?
a) conductive
b) sensorineural
c) mixed
d) central
a) conductive
He speaks softly because he can hear himself better through bone conduction.
Changes in the spiral ganglia and hair cells are quite marked in
a) conductive losses
b) psychogenic losses
c) sensorineural losses
d) functional losses
c) sensorineural losses
An increased reflection of sound on the tympanic membrane can be the result of _____?
a) a middle ear infection
b) a head injury
c) tinnitus
d) none of the above
a) a middle ear infection
Fluid behind the ear drum causes loss of tautness, thus the ear drum doesn’t vibrate, but just reflects the incoming sound.
A small hole in the tympanic membrane can cause a loss of ____?
a) 0 dB HTL
b) 10-15 dB HTL
c) 20-25 dB HTL
d) 30-35 dB HTL
b) 10-15 dB HTL
Straight memorization.
A blocking of or closure of the ear canal is called ____?
a) ataxia
b) atresia
c) aphasia
d) stenosis
b) atresia
Loss of ability to understand or express speech, caused by brain damage.
a) stenosis
b) aphasia
c) ataxia
d) atresia
b) aphasia
The abnormal narrowing of a passage in the body.
a) ataxia
b) aphasia
c) stenosis
d) atresia
c) stenosis
Poor coordination and unsteadiness due to the brain’s failure to regulate the body’s posture and regulate the strength and direction of limb movements.
a) stenosis
b) aphasia
c) ataxia
d) atresia
c) ataxia
The procedure of replacing the stapes with an artificial prosthesis is called _____?
a) myringotomy
b) stapedectomy
c) tympanoplasty
d) fenestration
b) stapedectomy
A surgical incision into the eardrum, to relieve pressure or drain fluid.
a) Myringotomy
b) Tympanoplasty
c) Fenestration
a) Myringotomy
The surgical operation performed for the reconstruction of the eardrum (tympanic membrane) and/or the small bones of the middle ear (ossicles).
a) Myringotomy
b) Fenestration
c) Tympanoplasty
c) Tympanoplasty
The operation of cutting an opening in the bony labyrinth between the inner ear and tympanum to replace natural fenestrae that are not functional
a) Tympanoplasty
b) Fenestration
c) Myringotomy
b) Fenestration
Hearing loss from noise exposure is usually due to
a) obstruction of the external canal
b) cochlear hair cell damage
c) overproduction of endolymph
d) labyrinthitis
b) cochlear hair cell damage
Noise exposure overworks the hair cells. The other answers don’t relate.
Earmold tubing comes in several inside diameters. The size most often recommended by manufacturers is:
a) #16
b) #15
c) #14
d) #13
d) #13
Straight memorization
If a person has UCL of 90 dB and an SRT of 45 dB, the dynamic range is
a) 90 dB
b) 45 dB
c) 135 dB
d) cannot be computed from the information given
b) 45 dB
Bottom to top. Do the math.
Which of the following is part of the inner ear?
a) vestibule
b) endolymph
c) tectorial membrane
d) all of the above
e) none of the above
d) all of the above
You should be able to locate all the parts of the inner ear, and have a vague idea what they do.
A person with a dynamic range of 50 dB and a TD of 100 dBHL would probably
a) have no trouble listening to a phonograph record
b) be uncomfortable with a live orchestra playing the same music
c) have difficulty with quiet conversation
d) all of the above
d) all of the above
The ossicles form a link between
a) the concha and the round window
b) the tympanic membrane and the scala tympani
c) the cochlea and the middle ear
d) the tympanic membrane and the oval window
d) the tympanic membrane and the oval window
Decibels
a) can be added together
b) are based on a logarithmic scale
c) all of the above
d) none of the above
b) are based on a logarithmic scale
Decibels are relative, and they increase on a ratio.
