Audiology PRAXIS practice 1 The caloric test is designed to stimulate wh ich of the following structures - ✔✔The lateral semicircular canal To reduce adverse noise effects, the audiologist should make what adjustment - ✔✔Enable expansion. Expansion reduces the gain of low -level ambient sounds. Individuals with normal hearing sensitivity in one ear and a severe hearing loss in the other ear experience... - ✔✔More difficulty understanding speech when the speaker moves closer to the ear with hearing loss Patient has persistent imbalance for the past 6 months. One severe attack o f true rotary vertigo 6 months ago. She has limited her activities because quick head movements increase symptoms. VNG reveals normal saccade, optokintetic, and smooth pursuit testing. A second -degree left -
beating nystagmus is observed during gaze testing without fixation. Postactive head -shake nystagmus reveals a left -beating nystagmus. No positioning or positional nystagmus is observed. Bilateral bithermal caloric results indicate a 50 percent right weakness with no significant directional preponderance. - ✔✔a dynamically uncompensated peripheral pathology affecting the right ear Videonystagmography results normally provide site -of-lesion specific information (i.e., caloric irrigations) to determine probable side of weakness. In this example, the patient h ad a 50 percent right peripheral vestibular weakness, suggesting a peripheral pathology affecting the right side. The postactive head -shake left -beating nystagmus suggests that the lesion is dynamically uncompensated. Which of the following is a possible outcome of an audiologist using a physician's NPI for billing rather than using his or her own NPI? - ✔✔The incorrect validation of the physician as the predominant provider of audiology services. It is detrimental to the profession of audiology to have audiology services billed under the NPI of a physician. Doing so can skew the Medicare claims data to incorrectly indicate that physicians are the predominant providers of audiology services and, as a result, limit the role of the profession of audiology in national and regional audiology coding and reimbursement processes. Auditory brainstem response (ABR) testing indicates a prolonged wave I -V latency. These findings are consistent with which of th e following? - ✔✔Retrocochlear pathology, such as an acoustic neuroma A prolonged interval between waves I and V indicates a pathology in the area affected by neural conduction in the VIIIth nerve and the brainstem. Which of the following is the most app ropriate action for an audiologist to take when counseling a patient with a hearing impairment? - ✔✔Informing the patient of his or her rehabilitative options Informing patients about rehabilitative options offers them opportunities to learn how to manage hearing loss and improve communication. Which of the following is an accurate statement concerning measures of speechreading ability? - ✔✔The most realistic measures of speechreading ability are administered in a combined auditory -visual mode. Speechrea ding in actual use depends on both auditory and visual input for most clients. The measure of speechreading ability that best reflects a client's real ability is one that is administered in a combined auditory -visual mode. One component of the adult aural rehabilitation process is listening training. In listening training, the patient is trained to - ✔✔be alert, attentive, and set to receive communication Being alert, attentive, and set to receive communication are the important components to improve list ening skills. During subjective verification of hearing -aid directionality, a patient indicates that when noise comes from behind, the noise seems especially loud. Which of the following is most likely the cause? - ✔✔The microphones are probably wired bac kward. Directional microphones are designed to reduce sounds from behind the listener. If the listener perceives that sounds are loud from behind, likely the front microphone is functioning like the back microphone and undesirable sounds are not being can celled from behind. Hearing -conservation programs for children often include screening with pure tones and acoustic immittance measures, whereas such programs for adults will likely use only pure tones for screening. Which of the following justifies this difference? - ✔✔There is a significantly higher incidence of middle -ear pathology among children than among adults. Acoustic -immittance measures, although they do not test hearing sensitivity, detect the possible presence of middle -ear pathology. For appr opriate hearing care, therefore, both acoustic -
immittance and pure -tone measures are necessary for children. Which of the following is true of the occlusion effect observed during pure tone audiometry? - ✔✔It can affect the measurement of bone -conduction thresholds at low frequencies. The occlusion effect is the sensation of increased loudness of low -frequency sounds transmitted through bone conduction when the outer ear is blocked. In cases of conductive hearing loss, the greater the degree of hearing lo ss, the louder these sounds are likely to be perceived, so measurement of the bone -conduction threshold at low frequencies is affected.
