1 mm - ANSWER-How wide is the eustacian tube?
35 mm - ANSWER-How long is the eustacian tube?
,It helps to conduct sound vibration. - ANSWER-What is the function of the tympanic membrane?
pearly grey - ANSWER-What color is NORMAL for the tympanic membrane?
annulus - ANSWER-The fibrous border that attaches the eardrum to the temporal bone ?
perilymph - ANSWER-The bony labyrinth surrounds and protects the membranous labyrinth, which is
bathed in a fluid called ___________.
hearing
balance and equilirium - ANSWER-What are the two functions of the ears?

seborrheic dermatitis - ANSWER-A flaky scaliness on or behind the auricle usually indicates
_____________________ and can be present on the scalp and facial structures as well
5 mm - ANSWER-The largest speculum that the ear canal can accommodate ____mm.
gently irrigate the canal with warm water - ANSWER-If the tympanic membrane cannot be visualized
because of cerumen, the cerumen may be removed how?
Weber and Rinne tests - ANSWER-Name two tests used to assess a patient's hearing ability.
Weber test - ANSWER-This test for hearing uses bone conduction to test lateralization of sound.
What is it called?
Rinne test - ANSWER-This hearing test is done by shifting the stem of a vibrating tuning fork between
two positions: 2 inches from the opening of the ear canal and against the mastoid bone. As the
position changes, the patient is asked to indicate which tone is louder or when the tone is no longer
available. What is it called?
The Weber Test - ANSWER-Results of this test are used to determine whether the patient has
conductive hearing loss or sensorineural hearing loss. Which test?
,air conduction - ANSWER-Which type of conduction should be longer for sensiorneural hearing loss?
Air or Bone?
TRUE - ANSWER-Conductive hearing loss such as from otosclerosis or otitis media, when performing
the Weber test the sound lateralizes toward the affected ear T/F?
Bone - ANSWER-Weber test just does ____ conduction.
Audiometry confirms a client's chronic progressive hearing loss. Further investigation reveals
ankylosis of the stapes in the oval window, a condition that prevents sound transmission. This type of
hearing loss is called a: - ANSWER-conductive hearing loss
pars tensa - ANSWER-Approximately 80% of the tympanic membrane is composed of all three layers
and is called the ___________.
pars flaccida - ANSWER-The remaining 20% of the tympanic membrane that lacks the middle layer is
called ?
frequency, pitch, and intensity - ANSWER-Name three characteristics that are important when
evaluating hearing.
frequency - ANSWER-The number of sound waves emanating from a source per second, measured as
cycles per second, or Hertz.
20-20,000 Hz - ANSWER-What is the range of human hearing?
intensity - ANSWER-Loudness of sound is known as _________.
decibel (dB) - ANSWER-The unit for measuring loudness, the pressure exerted by sound. Hearing loss
is measured using this unit.
0-15 dB - ANSWER-The normal hearing in decibels ?
, >15-25 dB - ANSWER-Slight hearing loss in decibels ?
>25-40 dB - ANSWER-Mild hearing loss in decibels ?
>40-55 dB - ANSWER-Moderate hearing loss in decibels ?
>55-70 dB - ANSWER-moderately severe hearing loss in decibels ?
>70-90 dB - ANSWER-Severe hearing loss in decibels ?
>90 - ANSWER-Profound hearing loss in decibels ?
tympanogram - ANSWER-measures middle ear muscle reflex to sound stimulation and compliance of
the tympanic membrane by changing the air pressure in a sealed ear canal ?
-family history of sensorineural impairment
-congential malformations of the cranial structure (ear)
-low birth weight (<1500g)
-use of ototoxic medications (e.g., gentamycin, loop diuretics)
-recurrent ear infections
-bacterial meningitis
-chronic exposure to loud noises (jobs, hobbies)
-perforation of the tympanic membrane - ANSWER-Risk factors for hearing loss (8) ?
presbycusis - ANSWER-hearing loss associated with old age is called ?
Aural Rehabilitation - ANSWER-intervention aimed at minimizing and alleviating the communication
difficulties associated with hearing loss ? Can be used if hearing loss is permanent or untreatable or if
the patient elects not to be treated.
