1.  Select which 4 different types of tympanometry results can occur during immitance testing:
  1. A, B, C, Z
  2. A, B, Ad, X
  3. A, B, C, As
  4. A, B, C, D
2.  Tympanometry alone looks at which three different types of impedance in the assessment of the middle ear?
  1. Immittance, admittance, resistance
  2. Immittance, resistance, conductance
  3. Admittance, resistance, weight
  4. Immittance, admittance, pressure
3.  If Acoustic Reflex Threshold (ART) results can help make a differential diagnosis of a patient's hearing, what information can reflexometry assist with?
  1. Nature of loss only, conductive vs sensory
  2. Nature of loss only, conductive vs sensory vs neural
  3. Nature or loss (conductive, sensory, neural) and degree of loss
  4. None of the above
4.  In what conditions will reflexes most likely be elicited?
  1. Normal middle ear function
  2. Loud enough stimulus to elicit the response
  3. No abnormal adaptation to stimulus
  4. All of the above
5.  If your patient had a bilateral mild to moderate cochlear loss (>50dBHL) and you performed reflexometry, what type of response would you typically see?
  1. No reflexes would be elicited
  2. Normal reflexes (around 80 to 90dB)
  3. Reflexes would be elicited above 100dB
  4. Mixed result, some reflexes where loss is normal and no reflexes where there is a hearing loss.
6.  If ipsilateral and contralateral reflexes are absent in both ears in a patient, what statement is most likely correct?
  1. They have a moderate conductive loss in one ear only
  2. They have a mild bilateral sensorineural loss
  3. They have a retrocochlear loss
  4. They have a moderate bilateral conductive loss
7.  Interacoustics Titan machine can perform the following functions:
  1. Tympanometry
  2. Tympanometry, reflexometry
  3. Tympanometry, reflexometry, decay assessment
  4. Tympanometry, reflexometry, decay assessment, OAE's.
8.  Were you to remove the Interacoustics Titan machine from the cradle, which of the following answers is correct?
  1. All tests that were performed via PC in the cradle are still available in hand held mode
  2. You can upload and download patient data from the hand held machine to the PC when finished testing
  3. You can save results into a database, e.g. NOAH, after testing through placing the Titan back into the cradle and uploading the results
  4. All of the above
9.  What testing parameters under Tympanometry set up can you personalize?
  1. Name of test, start & stop pressures, probe tone frequency, normative boxes and pump speeds
  2. Name of test only
  3. Start and Stop pressures only
  4. Pump Speed only
10.  Under Reflexometry, which testing parameter can you personalize?
  1. Reflex parameters only
  2. Reflex parameters, threshold criteria and stimuli parameters
  3. Threshold criteria only
  4. Stimuli parameters only
