Practice questions
- In comparative mammalian studies of the peripheral acoustic analyzer, which set of structures was followed during structural evolution?
- A comparative study relates mammalian ear structure to the acoustic properties of the animals’ environments. Which interpretation best matches this finding?
- A student says that comparative research on mammalian hearing development considered only embryonic formation. Which correction is best supported?
- Which conclusion is appropriately cautious when using comparative evidence about ecological groups and mammalian ear structure?
- Which statement best summarizes the evolutionary emphasis reported in the comparative study of mammalian hearing organs?
- Which cranial nerve is described in the supplied review as serving the organs of hearing and equilibrium?
- A patient has auditory neuropathy. Which combination of findings most closely matches the review’s description?
- In a person with auditory neuropathy, cochlear amplification is found to be normal. What can be concluded about auditory neural function from this finding alone?
- A patient with auditory neuropathy has abnormal auditory neural function but an unremarkable vestibular test. Which interpretation is most consistent with the review?
- Which mechanisms are identified in the review as possible causes of neuropathies affecting the vestibulocochlear nerve?
- A study examined 78 men occupationally exposed to carbon monoxide. Which percentage had receptive hearing impairment in that reported group?
- In the reported group of 78 men occupationally exposed to carbon monoxide, which finding was observed in 79.5%?
- What is the most appropriate interpretation of the carbon-monoxide study’s reported hearing and vestibular findings?
- In a study of patients with hearing and equilibrium disturbances considered central in origin, hearing disturbance was associated with focal EEG abnormalities in which leads?
- In the same report on central-origin hearing and equilibrium disturbances, which EEG pattern was associated with vertigo?
- A learner uses the reported EEG pattern in a 52-patient study to claim that left temporal EEG abnormalities are a universal test for identifying the side of an ear lesion. Which response is best?
- A patient has vertigo. Based only on the EEG association reported in the cited central-origin study, which statement is most defensible?
- Which statement best distinguishes the reported evidence on auditory neuropathy from the reported EEG findings in central-origin disturbances?
