3.  What should be tested prior to consideration of cochlear implantation compared to traditional hearing aids for a patient with MELAS? Auditory processing testing Distortion Product Otoacoustic Emissions The integrity of brainstem and cortical auditory pathways Neural Response Telemetry

4.  Which of the following options should be considered for a patient with asymmetric hearing loss and word recognition scores? BiCROS Bilateral hearing aids Aiding the better ear only All of the above

5.  Patient W's gradual hearing and vision decline were characteristic of which type of Usher Syndrome? Type I Type II Type III All of the above

8.  Bilateral hearing aids can provide a user with abilities that a BiCROS system cannot. Which of the items listed below do bilateral hearing aids have the potential to provide?
