A patient presents with normal hearing in the right ear and a severe cochlear loss in the left ear. Based on the chart, what would you expect the acoustic reflex results to be?
A patient presents with normal hearing in the right ear and a severe cochlear loss in the left ear. Based on the chart, what would you expect the acoustic reflex results to be?
- Normal reflexes for right ipsilateral and contralateral, absent reflexes for left ipsilateral and contralateral.
- Absent reflexes bilaterally.
- Normal reflexes for right ipsilateral and contralateral, elevated or absent reflexes for left ipsilateral and contralateral. (correct)
- Elevated or absent reflexes for right ipsilateral and contralateral, normal reflexes for left ipsilateral and contralateral.
A patient's acoustic reflex testing reveals absent reflexes on the right side, and elevated or absent reflexes when stimulating the left ear and measuring on the right. What is the most likely location of the lesion, based on this data?
A patient's acoustic reflex testing reveals absent reflexes on the right side, and elevated or absent reflexes when stimulating the left ear and measuring on the right. What is the most likely location of the lesion, based on this data?
- Bilateral Conductive Loss
- Right Conductive Loss (correct)
- Brainstem Midline Lesion
- Left Cochlear Loss
Which of the following lesion locations would MOST likely cause absent ipsilateral reflexes and elevated contralateral reflexes?
Which of the following lesion locations would MOST likely cause absent ipsilateral reflexes and elevated contralateral reflexes?
- Left seventh nerve
- Left mild cochlear loss
- Right conductive loss (correct)
- Right eighth nerve
A patient's acoustic reflex results show absent reflexes bilaterally. Which condition could be responsible for these results?
A patient's acoustic reflex results show absent reflexes bilaterally. Which condition could be responsible for these results?
A patient has normal hearing thresholds. However, acoustic reflex testing reveals present reflexes with decay in the right ear with ipsilateral stimulation. Based on the chart, where is the most likely location of the lesion?
A patient has normal hearing thresholds. However, acoustic reflex testing reveals present reflexes with decay in the right ear with ipsilateral stimulation. Based on the chart, where is the most likely location of the lesion?
A patient presents with symptoms suggesting a possible lesion affecting cranial nerves. Acoustic reflex testing reveals absent/elevated reflexes with decay in the right ear upon ipsilateral stimulation, and normal reflexes in the left ear. Based on this information and the provided data, which cranial nerve is MOST likely affected?

Given the audiogram, which of the following statements is most accurate regarding the patient's hearing thresholds?
Given the audiogram, which of the following statements is most accurate regarding the patient's hearing thresholds?
Compared to normal acoustic reflex thresholds, how would you categorize the acoustic reflex thresholds for the right ear in the case study?

Flashcards
Left Severe Cochlear Loss
Left Severe Cochlear Loss
With a left severe cochlear loss, right ipsi and contra are normal. Left contra and ipsi are higher/absent, yet within threshold-based norms.
Right Conductive Loss
Right Conductive Loss
With a right conductive loss, right ipsi is absent while contra is likely elevated or absent. Left contra is likely absent while ipsi is normal.
Right Eighth Nerve Issue
Right Eighth Nerve Issue
With a right eighth nerve issue, right ipsi and contra show absent/elevated/present with decay. Left ipsi and contra are normal.
