Exam Preview for 40228: A Comprehensive Overview of Auditory Brains

A Comprehensive Overview of Auditory Brainstem Responses (ABR)

Please note: exam questions are subject to change.

1. What does Wave I in Auditory Brainstem Responses (ABR) represent? Activity of the auditory brainstem Potentials from the eighth cranial nerve Response from the medial geniculate body Signal from the cochlear amplifier
2. Which stimulus type is most commonly used to generate a robust Wave V in ABR testing? White noise Pure tones Click stimuli Narrowband noise
3. A prolonged I-V interpeak latency in an ABR recording is most indicative of which of the following? Cochlear damage Brainstem dysfunction Auditory neuropathy Middle ear pathology
4. When conducting ABR tests in neonates, why is the chirp stimulus preferred over the click stimulus? It reduces test duration without improving results. It is less affected by background noise. It provides higher Wave V amplitude and better threshold estimation. It is easier to administer using bone conduction.
5. What is the significance of observing absent ABR waves but present otoacoustic emissions in a patient? Sensorineural hearing loss Auditory neuropathy Central auditory processing disorder Conductive hearing loss
