module 21 part 1 Flashcards
the tympanic membrane is inspected by what instrument
otoscope
the patient with normal acuity can correctly repeat what was whispered
whisper test
used to test lateralization of sound
weber test
a person hears the sound equally in both ears or describes the sound at the center
weber test
px hears the sound better IN THE AFFECTED EAR
conductive hearing loss
px hears the sound in the BETTER HEARING EAR
sensorineural hearing loss
otosclerosis or otitis media leads to what hearing loss
conductive hearing loss
damage to the cochlear or vestibulocochlear nerve leads to what hearing loss
sensorineural hearing loss
used to distinguish between conductive hearing loss and sensorineural hearing loss
rinne test
which should be louder in normal px, air conducted or bone conducted?
air conducted
the single most important diagnostic instrument in detecting hearing loss
audiometry
the sound stimulus consists of a pure or musical tone
pure tone audiometry
the spoken word is used to determine the ability to hear and discriminate sounds and words
speech audiometry
refers to the number of sound waves emanating from a source per second
frequency
the term used to describe frequency
pitch
the unit for measuring loudness is the ______
dB / decibel
measures middle ear muscle reflex to sound stimulation
tympanogram
a detectable electrical potential from cranial nerve VII
auditory brain stem response
the measurement and graphic recording of the changes in electrical potentials created by EYE MOVEMENTS
electronystagmography
investigate postural control capabilities such as vertigo
platform posturography
what type of hearing loss:
caused by external of middle ear problem
conductive hearing loss
what type of hearing loss: caused by damage to the cochlea or vestibulocochlear nerve
sensorineural hearing loss
what type of hearing loss: both conductive and sensorineural
mixed hearing loss
what type of hearing loss:
caused by emotional problem
functional hearing loss
perception of sound; often “ringing in the ears”
tinnitus
normally accumulates in the external canal in various amount and colors
cerumen
a person with _____ hears bone conducted sound as LONGER than air
conductive hearing loss
a person with _____ hears air conducted sound as LONGER than bone
sensorineural hearing loss
what is the speech range or speech frequencies
500 to 2000 hz
used to assess the vestibule ocular system by analyzing compensatory eye movements
sinusoidal harmonic acceleration
evaluates suspected perilymphatic fistula and new onset conductive hearing loss
middle ear endoscopy
