1.
A lesion is present in the inner ear and the
VIII N. This is which type of hearing loss?
1. conductive
2. mixed
3. •sensorineural
2.
Tubes that are closed at one end (like the ear
canal) resonate to a frequency
1. that depends upon how wide the
diameter of the tube is
2. •that has a wavelength 4 times the length
of the tube
3. that is determined by the diameter of the
ear canal
4. A and C are true
3.
Cerumen is formed from
1. sebacious glands
2. apocrine glands
3. eccrine glands
4. celllular debris, hair
5. •all the above
4.
Using audiometry it has been determined
that your bone conduction thresholds are
normal, but you have a 40 dB loss by air
conduction. The type of hearing loss you
have is
1. sensorineural
2. •conductive
3. mixed
5.
Using an otoscope you could
1. measure hearing sensitivity
2. •observe the cone of light
3. obtain a type B tympanogram
6.
If the audiogram shows a hearing loss, you
1. •could have a normal tympanogram
2. would expect the eardrum to appear
abnormal otoscopically
3. could not have a normal tympanogram
7.
A doorbell is judged to be equally loud as a
1000-Hz tone at 65 dB SPL. A dog barking
has a loudness of 75 phones. You conclude
that
1. •the dog is about twice as loud as the
doorbell
2. the dog sounds about 10 times as loud
since it has 10 times the intensity of the
doorbell
3. there is not enough information to
determine how loud the dog is compared to
the doorbell
8.
Using audiometry it has been determined
that your bone conduction thresholds show
a 30 dB hearing loss, and you have a 50 dB
loss by air conduction. The type of hearing
loss you have is
1. sensorineural
2. conductive
3. •mixed
9.
The child has a sensorineural hearing loss.
Which tympanogram type would you
predict?
1. •Type A (normal peak admittance,
normal middle ear pressure)
2. Type B (flattened)
3. Type C (normal peak admittance,
negative middle ear pressure)
10.
Earwax
1. normally is produced by sebaceous
glands located in the bony portion of the ear
canal
2. •normally is externalized by the growth
pattern of tissue in the ear canal
3. typically, will totally occlude the ear
canal, since the "massaging" action of the
mandible results in the wax making a
perfectly tight seal
11.
The pH of the tissue lining the ear canal is
higher than normal
1. creating an abundance of earwax
2. so a tympanostomy tube would be
recommended
3. •making an external otitis more probable
12.
An ear infection caused by bacteria is
1. •an acute otitis
2. a serous otitis
3. noninflammatory in nature
13.
The cone of light is considered to be
associated with the
Page 2

1. speculum of the otoscope
2. •eardrum
3. bony portion of the ear canal
14.
Which of the following is true?
1. Valsalva is credited with dividing the ear
into its three major divisions: the ear canal,
the eardrum, and the inner ear
2. •the cochlea is fluid filled and contains
the membranous labyrinth
3. the middle ear cavity is normally fluidfilled; the eustachian tube permits drainage
to enter the middle ear
15.
A lesion is present in the outer ear and the
middle ear. This is which type of hearing
loss?
1. •conductive
2. mixed
3. sensorineural
16.
The ear canal is "S" shaped
1. •protecting the eardrum from objects
inserted into the canal
2. allowing the external ear to maintain
homeothermy
3. improving our ability to hear high
frequency frication noise
4. all the above
17.
18.
19.
Hearing screening (for children 6 years and
older) is designed to detect hearing loss
greater than
1. 15 dB, the limits of the normal range
2. •20 dB, but only for frequencies at and
above 1000 Hz
3. 25 dB
There are two middle ear muscles
1. •the tensor tympani and the stapedius
muscle
2. which, when contracted, relax the middle
ear, allowing more energy to enter the inner
ear
3. that contract and stiffen the ossicular
chain, causing better sensitivity in the lower
frequencies
4. both A and C are true
