Practice AudiologyA patient comes to a clinic complaining of short, intense dizzy spells. An audiologist suspects that the
patient may have benign paroxysmal positional vertigo (BPPV). Which of the following tests is most
appropriate to use to confirm the diagnosis?
A.Headshaking test
B.Ocular VEMP test
C.Dix-Hallpike test
D.Fistula test - ANS Dix-Hallpike
The test used to diagnose BPPV is the Dix-Hallpike, which is a positioning test that assesses the presence
of otoconia in the semicircular canal.
0 dB0 decibels HL is best described by which of the following?
A. The intensity at which the audiometer produces no sound at any frequency
B. The different sound pressure levels that occur at different frequencies
C. The minimum level at which speech is understood 50 percent of the time
D. The intensity of 10 dB10 decibels SPL at 1000 Hz1000 hertz - ANS Option (B) is correct. 0 dB0 decibels
HL on an audiometer represents the minimum audible pressure needed at each frequency for an
individual with normal hearing to detect a pure tone. This value varies with frequency due to the
anatomic and physiologic properties of the auditory system.
An audiologist fit a patient with binaural, digital, behind-the-ear hearing aids three weeks ago. The
patient reports that the devices have provided suitable amplification in most environments but also
complains that soft background noise is distracting.
,To reduce the adverse noise effect, which of the following is the best adjustment for the audiologist to
make to the hearing aids?
A. Increasing the threshold kneepoint
B. Decreasing the compression ratio
C. Enabling wide dynamic range compression
D. Enabling expANSion - ANS Option (D) is correct. ExpANSion reduces the gain of low-level ambient
sounds.
Individuals with normal hearing sensitivity in one ear and a severe hearing loss in the other ear
experience which of the following?
A. An improvement in speech understanding when the noise source is closer to the ear that has normal
hearing
B. Improved ability to localize when the noise source is closer to the ear that has hearing loss
C. Better speech understanding and localization as the reverberation time increases
D. Improved localization when the noise is at 0 degrees azimuth and the source is closer to the ear that
has hearing loss - ANS Option (A) is correct. For individuals with unilateral hearing loss, speech
intelligibility improves when the ear with better hearing is closer to the noise source. When this occurs,
the signal-to-noise ratio improves in the better ear.
Which of the following describes the relationship between the solid wave and the broken wave in the
figure?
A. They are in phase with one another.
B. The broken line leads the solid line by 180° 180 degrees.
C. The solid line leads the broken line by 90° 90 degrees.
,D. The solid line lags the broken line by 90° 90 degrees. - ANS Option (D) is correct. The starting phase of
the solid line is 0°, and the starting phase of the broken line is 90°90 degrees. Therefore, the solid line
lags the broken line by 90°90 degrees.
A patient is seen for a vestibular evaluation with the primary complaint of persistent imbalance for the
past six months. The patient reports one severe attack of true rotary vertigo six months ago and since
then fears that another will occur. The patient has limited many activities because quick head
movements increase symptoms.
Videonystagmography (VNG) results indicate normal saccade, optokinetic, and smooth pursuit testing. A
left-beating nystagmus is observed during gaze testing without fixation. Post-headshake nystagmus
reveals a left-beating nystagmus. No positioning or positional nystagmus is observed. Bilateral bithermal
caloric test results indicate a 50 percent right weakness with no significant directional preponderance.
Based on the preceding information, the patient most likely has which of the following?
A. A central vestibular pathology
B. A statically uncompensated peripheral pathology affecting t - ANS Option (D) is correct.
Videonystagmography (VNG) results normally provide site-of-lesion specific information to determine
the probable side of weakness. In this example, the patient had a 50 percent right peripheral vestibular
weakness, suggesting a peripheral pathology affecting the right side. The post-headshake left-beating
nystagmus suggests that the lesion is dynamically uncompensated.
Research shows that people wait as long as seven years before they seek hearing health care services
due to the negative stigma associated with hearing loss. Which of the following is most likely to occur
with untreated hearing loss?
A. Vision decline
B. Cognitive decline
C. Chronic fatigue
, D. Debilitating tinnitus - ANS Option (B) is correct. The consequences of untreated hearing loss include
lower signal quality in the brain (leading to a higher cognitive load), a change in the structure of the
brain, social disengagement, behavior changes, and health issues like dementia, depression, fatigue, and
anxiety.
A 65-year-old woman is fitted with her first pair of hearing aids. She and her husband are attending their
first audiologic rehabilitation session about communication strategies. She states that she struggles to
understand what her husband says "because he uses too many words." Which of the following
facilitative strategies would be the most appropriate to improve the situation?
A. She should ask him to write down key words and topics.
B. She should make sure the lighting is appropriate for speechreading.
C. She should ask him to use shorter phrases and pause often.
D. She should encourage him to speak very slowly and exaggerate his enunciation. - ANS Option (C) is
correct. She should use a message-tailoring strategy that teaches her communication partner to use
simple syntax and multiple shorter phrases rather than one longer one.
A patient with new hearing aids complains of difficulty understanding speech in noisy environments
such as restaurants. The audiologist verifies that the cardioid polar plots with fixed directionality are
working appropriately. Which of the following is the most appropriate action for the audiologist to take
when counseling the patient?
A. Encouraging the patient to consider purchasing hearing aids with omnidirectional polar plots
B. Recommending that the patient avoid reverberant environments when first wearing the new hearing
aids
C. Advising the patient to face the noise in certain environments to maximize the directional function of
the hearing aids
D. Counseling the patient to sit with the back toward the noise to maximize the directional function of
the hearing aids - ANS Option (D) is correct. Counseling patients about where to sit in noisy
environments will maximize the capability of the directionality feature of the hearing aids. Cardioid
microphones in hearing aids pick up sounds with sensitivity from the front and sides but poorly from the
rear. It is therefore best to sit or stand with the back to the noise that is interfering with hearing and let
the sound come from the front or sides.
