VIII Vestibucochlear
The external ear is separated from the middle ear by a disk-shaped structure called the
________________________. - CORRECT ANSWER - tympanic membrane
The _______ collects the sound waves and directs vibrations in to the external auditory canal. -
CORRECT ANSWER - auricle (pinna)
A brown, waxlike substance secreted by ceruminous glands is called? - CORRECT
ANSWER - cerumen (ear wax)
How wide is the eustacian tube? - CORRECT ANSWER - 1 mm
How long is the eustacian tube? - CORRECT ANSWER - 35 mm
What is the function of the tympanic membrane? - CORRECT ANSWER - It helps to
conduct sound vibration.
What color is NORMAL for the tympanic membrane? - CORRECT ANSWER - pearly
grey
Approximately 80% of the tympanic membrane is composed of all three layers and is called the
___________. - CORRECT ANSWER - pars tensa
,The remaining 20% of the tympanic membrane that lacks the middle layer is called ? -
CORRECT ANSWER - pars flaccida
The fibrous border that attaches the eardrum to the temporal bone ? - CORRECT
ANSWER - annulus
The bony labyrinth surrounds and protects the membranous labyrinth, which is bathed in a fluid
called ___________. - CORRECT ANSWER - perilymph
What are the two functions of the ears? - CORRECT ANSWER - hearing
balance and equilirium
Helps to equalize pressure in the ear ? - CORRECT ANSWER - eustacian tube
A flaky scaliness on or behind the auricle usually indicates _____________________ and can be
present on the scalp and facial structures as well - CORRECT ANSWER - seborrheic
dermatitis
The largest speculum that the ear canal can accommodate ____mm. - CORRECT
ANSWER - 5 mm
If the tympanic membrane cannot be visualized because of cerumen, the cerumen may be
removed how? - CORRECT ANSWER - gently irrigate the canal with warm water
Name two tests used to assess a patient's hearing ability. - CORRECT ANSWER - Weber
and Rinne tests
This test for hearing uses bone conduction to test lateralization of sound. What is it called? -
CORRECT ANSWER - Weber test
,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? - CORRECT ANSWER - Rinne test
Results of this test are used to determine whether the patient has conductive hearing loss or
sensorineural hearing loss. Which test? - CORRECT ANSWER - The Weber Test
Which type of conduction should be longer for sensiorneural hearing loss? Air or Bone? -
CORRECT ANSWER - air conduction
Conductive hearing loss such as from otosclerosis or otitis media, when performing the Weber
test the sound lateralizes toward the affected ear T/F? - CORRECT ANSWER - TRUE
Weber test just does ____ conduction. - CORRECT ANSWER - Bone
conductive hearing loss - CORRECT ANSWER - 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:
Name three characteristics that are important when evaluating hearing. - CORRECT
ANSWER - frequency, pitch, and intensity
The number of sound waves emanating from a source per second, measured as cycles per
second, or Hertz. - CORRECT ANSWER - frequency
What is the range of human hearing? - CORRECT ANSWER - 20-20,000 Hz
Loudness of sound is known as _________. - CORRECT ANSWER - intensity
, The unit for measuring loudness, the pressure exerted by sound. Hearing loss is measured using
this unit. - CORRECT ANSWER - decibel (dB)
The normal hearing in decibels ? - CORRECT ANSWER - 0-15 dB
Slight hearing loss in decibels ? - CORRECT ANSWER - >15-25 dB
Mild hearing loss in decibels ? - CORRECT ANSWER - >25-40 dB
Moderate hearing loss in decibels ? - CORRECT ANSWER - >40-55 dB
moderately severe hearing loss in decibels ? - CORRECT ANSWER - >55-70 dB
Severe hearing loss in decibels ? - CORRECT ANSWER - >70-90 dB
Profound hearing loss in decibels ? - CORRECT ANSWER - >90
measures middle ear muscle reflex to sound stimulation and compliance of the tympanic
membrane by changing the air pressure in a sealed ear canal ? - CORRECT ANSWER -
tympanogram
Risk factors for hearing loss (8) ? - CORRECT ANSWER - -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)
