Clinical Considerations for Cochlear Implant Mapping with Electrical Stapedial Reflex Testing

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

1.  What does it mean when the electrical stapedial reflex is a “bilateral” reflex?
  1. It can only be stimulated and recorded in the ipsilateral ear to the cochlear implant
  2. It can only be stimulated and recorded in it can only be recorded in the contralateral ear to the cochlear implant
  3. It can be recorded in both/either the ipsilateral or contralateral ear to cochlear implant being stimulated
  4. It cannot be recorded at all.
2.  Which of the following is a contraindication for performing ESRT on a patient with a cochlear implant?
  1. Patient has a history of otosclerosis or ossicular chain replacement surgery
  2. The patient must be older than 39 years old.
  3. The patient's exam showed nothing of concern.
  4. The patient has no history of otosclerosis.
3.  When performing eSRT, what does a rising tracing on the immittance bridge screen usually indicate?
  1. A poor fitting immittance probe, with a possible leak where probe tip is moving out of the ear
  2. Negative middle ear pressure
  3. Positive middle ear pressure
  4. Nothing unusual
4.  What type of tympanic membrane defection should I expect to see on an eSRT tracing?
  1. A positive (upward) tympanic membrane defection
  2. A negative (downward) tympanic membrane defection
  3. With a positive upward or negative downward, the clinician should expect to see any type of deflection on eSRT
  4. The clinician should not expect to see anything
5.  What type of measure is Electrical Stapedial Reflex Testing (eSRT)?
  1. A behavioral measure
  2. An objective measure
  3. An electrophysiological measure
  4. It's not any type of measure
