1.  Which of the following sets of transducers is preferred for pediatric ABR assessment?
  1. Insert earphones and supra-aural earphones
  2. Supra-aural earphones and bone oscillator
  3. Supra-aural earphones and loudspeaker
  4. Insert earphones and bone oscillator
2.  Which one of the following stimulus rates is most appropriate for presentation of frequency-specific (tone burst) stimuli for efficient ABR measurement?
  1. 1.1 / sec
  2. 11.1 / sec
  3. 37.7 / sec
  4. 99.9 / sec
3.  How many channels is (are) generally adequate for ABR measurement?
  1. 1 channel
  2. 2 channels
  3. 4 channels
  4. 8 channels
4.  In addition to ABR, another objective auditory test is:
  1. Pure tone audiometry
  2. Speech audiometry
  3. Real ear measurements
  4. Otoacoustic emissions
5.  ASSR is most valuable as a supplement to ABR for estimation of hearing loss in children with:
  1. Normal hearing sensitivity
  2. severe-to-profound hearing loss
  3. Conductive hearing loss
  4. Central auditory dysfunction
6.  Which one of the following does NOT contribute to minimizing test time in ABR measurement?
  1. Reduction of patient muscle interference
  2. Stimulus presentation rate of> 37.7/sec
  3. Presentation of> 2000 stimuli (sweeps) under all test conditions
  4. Termination of signal averaging when ABR to noise ratio reaches 3:1
7.  The decision to perform bone conduction ABR measurement is determined by which factors:
  1. History of middle ear disease
  2. Prior finding of abnormal tympanograms
  3. Abnormally delayed wave I for click evoked air conduction ABR at high intensity
  4. The decision to perform bone conduction ABR measurement is determined by any of the above factors
8.  Which one of the following ABR recording techniques is useful in ruling out auditory neuropathy spectrum disorder (ANSD)?
  1. Comparison of ABR tracings for rarefaction versus condensation click stimuli
  2. Use of tone burst stimulus at 1000 Hz
  3. Bone conduction ABR measurement
  4. Changing stimulus rate from 11.1/sec to 21.1/sec
9.  The threshold for click evoked ABR is most closely associated with hearing sensitivity is which one of the following frequency regions.
  1. 250 to 500 Hz
  2. 500 to 1000 Hz
  3. 1000 to 2000 Hz
  4. 2000 to 4000 Hz
10.  The analysis of findings for multiple independent auditory tests in pediatric hearing assessment is important in clinical application of:
  1. Jerger principle
  2. 2017 JCIH recommendations
  3. the crosscheck principle
  4. state licensure guidelines
