2.  If a patient has a vestibular schwannoma in the right ear, what pattern might you expect for acoustic reflex testing? Present in all conditions Absent in all conditions Absent for conditions when the probe is in the right ear Absent for conditions when the stimulus is in the right ear

3.  Which of the following may indicate a poorer prognosis for hearing preservation outcomes? Pre-operative hearing loss Caloric weakness greater than 50% Present otoacoustic emissions Absent Auditory Brainstem Response (ABR)
