(44) Hearing Loss

Question 1

defn of conductove hearing loss vs sensorineural

Answer 1

conductive = transmission of sound thru air is dec
sensorineura = damage to hair cells in organ of corti that prevent depolarization/signal to auditory n

Question 2

etiology of Meniers disease

Answer 2

dec reabs of endolymph –> dialtion of labrynth

Question 3

Answer 3

fluctuating sensorineural hearing loss, vertigo, and tinniitus

Question 4

Answer 4

low Na diet; diuretics

Question 5

webber test results in conductive vs sensorineural hearing lossq

Answer 5

conductive: localizes to affected ear
sensorinueral: localizes to unaffected ear

Question 6

conductive or sensorineural:

all frequencies show elevated threshold on audiogram

Answer 6

conductive

= dec hearing lat all freq

Question 7

what freq are lost in sensprineural hearing loss

Answer 7

high

Question 8

what freq are lost in noise induced hearing loss

Answer 8

lower freq

Question 9

bilatera hearing loss in 20s or 30s think

Answer 9
