Otoacoustic Emissions: A Clinician's Guide

View Course Details Please note: exam questions are subject to change.

1.  Typical stimulus intensity levels for DPOAEs are:
  1. 80 dB SPL
  2. L2 = 55 dB SPL
  3. L2> L
  4. f2/f1 = 1.22
2.  Verification of the reliability of OAEs is best accomplished with:
  1. Repeating OAE recordings for the same ear and stimulus conditions
  2. Comparing OAE test results with an audiogram
  3. Asking patients to listen to the stimuli during the test
  4. Increasing stimulus intensity level to maximum
3.  Frequency specificity in OAE measurement is enhanced with:
  1. Use of a higher stimulus intensity level
  2. Recording with 3 stimuli within a single octave band
  3. Focusing on stimuli within a low frequency region
  4. Increasing the number of test frequencies per octave
4.  Which of the following is a criterion for the presence of OAE?
  1. Amplitude is at least -20 dB SPL
  2. Noise floor exceeds OAE amplitude by at least 6 dB
  3. OAE amplitude exceeds noise floor by at least 6 dB
  4. OAE amplitude is equivalent to noise floor
5.  Entirely normal OAEs generally rule out:
  1. Serious middle ear dysfunction
  2. Auditory processing disorder
  3. ANSD
  4. Traumatic brain injury (TBI)
6.  Which of the following has a greater effect on OAEs than on AABR?
  1. Vernix
  2. APD
  3. Age
  4. Gender
7.  Which disorder may NOT be identified with reliance only on OAEs in hearing screening?
  1. ANSD
  2. Vernix in the external ear canal
  3. Mesenchyme in the middle ear space
  4. Hearing loss due to ototoxicity
8.  Which document includes recommendations on OAE and AABR infant hearing screening?
  1. AAA Scope of Practice
  2. ASHA Scope of Practice
  3. State licensure laws and regulations
  4. 2007 Joint Committee on Infant Hearing Position Statement
9.  The strategy for hearing screening in the NICU recommended by JCIH 2007 is:
  1. AABR first with OAE screening if the AABR outcome is REFER
  2. OAE first with AABR screening if the OAE outcome is REFER
  3. Defer OAE and AABR hearing screening until first visit to the child's pediatrician
  4. OAE and AABR screenings for children with family history of hearing loss only
10.  Which of the following best describes REFER rates for WBN versus NICU populations?
  1. REFER rates are higher for the WBN population
  2. REFER rates are higher for the NICU population
  3. REFER rates are equivalent for the WBN and NICU populations
  4. REFER rates are only available for the WBN and not for the NICU population
11.  OAE recordings are influenced by status of the:
  1. Middle ear
  2. Inner hair cells
  3. Auditory brainstem
  4. Temporal lobe of the cerebral cortex
12.  OAEs are useful in the identification of ANSD because they:
  1. Detect middle ear dysfunction
  2. Detect inner hair cell dysfunction
  3. Unlike other tests, OAEs are a pre-neural test
  4. Require behavioral participation
13.  OAEs are useful in monitoring for ototoxicity because:
  1. They are a subjective auditory test procedure
  2. OAEs provide information on inner hair cell function
  3. Ototoxicity drugs often produce outer hair cell dysfunction
  4. OAEs require behavioral participation
14.  OAE findings are useful in early identification of suspected:
  1. False hearing loss
  2. Otitis media
  3. Otosclerosis
  4. Stroke
15.  In patients at risk for noise-induced hearing loss, OAE findings:
  1. Play no role if an audiogram is available
  2. Rule out neural abnormality
  3. Rule out middle ear pathology
  4. Sometimes provide early evidence of cochlear auditory dysfunction
