AUDIOLOGY PRAXIS EVALUATION TEST
QUESTIONS AND ANSWERS SET A+
✔✔*The embryonic inner ear forms from
a. ectoderm
b. mesoderm
c. endoderm
d. all of the above - ✔✔Ectoderm
the inner ear forms from the outer embryonic layer
the otic placodes thicken into ectodermal depressions which form otocysts which
differentiate into a cochlear pouch and a vestibular pouch
✔✔*A person with a conductive hearing loss riding in a car with open windows is likely
to hear a conversation
a. less well than normal hearing individuals
b. better than normal hearing individuals
c. the same as normal hearing individuals
d. with similar acuity but poorer discrimination - ✔✔Better than normal hearing
individuals (??)
The rational is that the conductive hearing loss removes the ambient background noise
so listeners are only able to hear the speech around them, and the road noise may
cause other passengers to speak louder
✔✔Which frequencies are most commonly affected worst by presbycusis?
a. lower frequencies
b. middle frequencies
c. higher frequencies
d. all of the above - ✔✔higher frequencies
✔✔Which of the following can cause tinnitus?
a. Meniere's disease
b. middle ear fluid
c. any type of hearing loss
,d. all of the above - ✔✔All of the above
✔✔*Gradenigo's syndrome consists of hearing loss plus all of the following symptoms
except
a. earache
b. otorrhea
c. vesicles
d. diplopia - ✔✔Vesicles
Gradenigo's syndrome is a syndrome characterized by severe earache, otorrhea or
discharge from the ear, and diplopia or double vision
Gradenigo's syndrome occurs when suppurative otitis media involves the petrous apex
and abducens nerve
✔✔*Which of the following statements about etiology is true of microtia and congenital
atresia during fetal development and prognosis for treatment?
a. microtic pinna + congenital atresia of the canal reflects earlier etiology and more
involved prognosis for reconstruction
b. congenital atresia of the canal with a normal pinna reflects earlier fetal etiology and a
better prognosis for reconstruction
c. microtic pinna + congenital atresia of the canal reflects earlier etiology and a better
prognosis for reconstruction
d. congenital atresia of the canal with normal pinna reflects earlier fetal etiology and a
more difficult reconstructive prognosis - ✔✔A microtic pinna with congenital atresia of
the canal reflects earlier developmental etiology and a more involved prognosis for
treatment
The outer ear develops first, followed by the middle and then inner ear. If the pinna is
impacted, then along with atresia it is likely that the middle ear is impacted and there
may not be a TM or ossicles
✔✔Which of the following statements about otosclerosis is true?
a. It causes only conductive hearing loss
b. It causes only a sensorineural hearing loss
c. It occurs most often in black populations
d. It occurs most often in white populations - ✔✔Otosclerosis occurs most often in white
populations
Abnormal bony growth on the stapes which creates a conductive loss, but can also
grow into the vestibule and labyrinth thus creating a sensorineural hearing loss
✔✔When indicated, a stapedectomy can
a. resolve or minimize a conductive hearing loss
b. cause or exacerbate a sensorineural hearing loss
c. cause both of the outcomes above at the same time
d. cause none of the above results - ✔✔Cause both of the outcomes above at the same
time
, The stapes can be freed entirely or replaced with a prosthesis, but this can further
damage the inner ear in the process
✔✔*Which of the following is true regarding myringoplasty
a. Ossiculoplasty should be performed
b. Stapedectomy should be performed
c. Neither of these should be performed
d. Both of these may be performed - ✔✔Ossiculoplasty should be performed
A stapedectomy should not be performed because creating an opening in the TM when
creating an opening in the inner ear could result in a sensorineural hearing loss
✔✔Which of the following can cause a reversible sensorineural hearing loss
a. Aspirin
b. Old age
c. diabetes
d. Meniere's - ✔✔Aspirin
when taken in large doses is known to cause a reversible SNHL
✔✔Noise exposure can cause hearing loss that is
a. temporary from short-term exposure
b. permanent from long-term exposure
c. permanent regardless of duration
d. both a and b - ✔✔Both a and b
noise exposure can cause a temporary threshold shift and long-term exposure to noise
can cause permanent SNHL
✔✔*Which statement is correct regarding the acoustics of speech sound production and
speech perception of listeners?
a. speech production is linear but listeners' perception runs the sounds together
b. speech production and listener perception are both linear
c. speech sounds are coarticulated but the listener's perception of them is linear
d. neither the production nor the perception of speech sounds is linear in nature -
✔✔Speech sounds are coarticulated but the listener's perception of them is linear
individual phonemes overlap but when we hear them our perception separates them
into discrete units heard in a linear fashion so we can differentiate among speech
sounds to understand what is said
✔✔*Which of the following is not a type of perceptual constancy in speech perception
a. vocal tract normalization
b. categorical perception
c. speech rate normalization
d. all types are constancy - ✔✔Categorical perception
perceptual constancy is the ability to recognize speech sounds across different
individual speakers
