◍ Head.
Answer: nan
◍ body.
Answer: nan
◍ Non-inverting: placed on Fz or Cz (high forehead)Inverting: placed either
M1/A1 or M2/A2Ground: Fpz or Nz: low forehead.
Answer: In a two-channel electrode montage, where you would place the
non-inverting, inverting, and ground electrodes?
◍ Wave I: Peripheral portion of the CN VIIIWave II: Central portion of the
CN VIIIWave III: Cochlear Nucleus Wave IV: SOCWave V: termination of
lateral lemniscus withing the Inferior colliculus.
Answer: What are the generators of the ABR?
◍ Far; short.
Answer: The ABR is a (far/short) field potential, and is considered a
(short/middle) latency response.
◍ Will.
Answer: Middle ear pathologies (will/will not) affect auditory evoked
, potentials
◍ tail.
Answer: nan
◍ main pancreatic duct.
Answer: nan
◍ neck.
Answer: nan
◍ fundus.
Answer: nan
◍ common bile duct.
Answer: nan
◍ cystic duct.
Answer: nan
◍ common hepatic duct.
Answer: nan
◍ Larger wave I amplitude.
Answer: What is a characteristic of the ipsilateral channel in ABR
recordings, when compared to the contralateral channel?
◍ Would not; would.
Answer: if you were recording an ABR from a patient who had no inner hair
cells (with intact outer hair cells), you most likely (would/would not) be able
to record an ABR. If this patient had no outer hair cells (with intact inner
hair cells), you most likely (would/would not) be able to record an ABR
◍ Heartbeat.
Answer: Which of the following is not typically a source of noise in ABR
recording? : Eye Blinking, Jaw clenching, heartbeat, neck tension
◍ Latency-based.
Answer: The most common way of classifying auditory evoked potentials is:
, ◍ 1. the absolute ABR latencies will decrease in higher frequencies so
therefore 4000Hz compared to 500Hz2. The 4000Hz tonebursts ABR
resembles the pattern of a click response.
Answer: What are two differences between a 500 Hz and a 4000Hz
toneburst ABR recording?
◍ We can predict that based on a 45 dB nHL ABR threshold, this patient
would likely have a mild (35dB with correction) degree of HL in the 2-4kHz
range.
Answer: you patient has a click evoked ABR threshold of 45 dB nHL and
the latency intensity function shown below; what can you say about his/her
hearing?
◍ hepatic ducts.
Answer: nan
◍ round ligament.
Answer: nan
◍ The ABR threshold will increase, latencies will increase at all levels.
Answer: Based on the case history and immittance testing, you suspect that
your patient has a conductive hearing loss, how do you expect your air
conduction ABR recordings to be impaired?
◍ falciform ligament.
Answer: nan
◍ The results are inconclusive, further testing is needed.
Answer: You record a click-evoked ABR and a 500 Hz tone burst ABR on a
baby who failed the newborn hearing screening. There is no response at the
levels of the equipment (and no signs of ANSD) what would you say about
this baby's hearing on your clinical report, based on these results?
◍ Larger.
Answer: Proposed corrections when predicting behavioral thresholds from
tone burst ABR are typically (smaller/larger) at low frequencies when
