Auditory Processing Disorder and Blast Trauma

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

1.  Although more widely recognized in the UK and Australia, a common cause of acoustic trauma in the US is:
  1. Otosclerosis
  2. Working in a call center
  3. Listening to music
  4. Presbycusis
2.  This cause of acoustic trauma results in progression of symptoms over a lifetime:
  1. Presbycusis
  2. Noise exposure
  3. Electrocution
  4. Traumatic brain injury (TBI)
3.  Blast injuries result in damage to:
  1. The peripheral auditory system
  2. The central auditory system
  3. Both A and B
  4. Only the physical structures of the ear
4.  Common auditory issues reported after acoustic trauma can include:
  1. Tinnitus
  2. Difficulty hearing in background noise
  3. Peripheral hearing loss
  4. All of the above
5.  The underlying etiology thought to result in tinnitus and/or hyperacusis in patients exposed to acoustic trauma is:
  1. Cochlear synaptopathy
  2. Inner hair cell damage
  3. Presbycusis
  4. Central auditory dysfunction
6.  Assessment of auditory processing skills in a patient who has experienced acoustic trauma should include:
  1. DPOAEs
  2. Speech in noise testing
  3. Pure tone assessment
  4. All of the above
7.  Pure tone audiometric findings for a patient who has experienced an acoustic trauma are likely to demonstrate:
  1. A severe to profound sensorineural hearing loss
  2. A mild conductive hearing loss
  3. A unilateral hearing loss
  4. A "normal" audiogram based on pure tone description
8.  The most common auditory deficit noted for those that have experienced acoustic trauma is:
  1. Temporal processing disorder
  2. Auditory memory
  3. Speech discrimination
  4. Both A and C
9.  Appropriate treatment for those that have had acoustic trauma is:
  1. Fitting of amplification, even in view of a "normal" audiogram
  2. Listening training such as with the LACE or CLEAR
  3. Use of digitally modulated (DM) system
  4. All of the above
10.  A medical treatment thought to assist with improvement of hearing and tinnitus following acoustic trauma is:
  1. Steroid treatment
  2. Hyperbaric oxygen treatment
  3. Vasoactive agents
  4. Carbogen
