Immittance Quiz Introduction

These questions will help assess your familiarity with ear anatomy and the journey of sound.

Immittance equipment currently in Wyoming's Child Development Centers is appropriate for use with children:

9 months of age or older

3 months of age or older

3 years of age or older

What does immittance screen?

The status of the cochlea

The status of the Auditory Pathway

The status of the middle ear system

Immittance screening can also provide information regarding:

Vision

Impacted ear wax, perforated eardrums, and P.E. tubes

Hair cells in the cochlea

True or False: Immittance also screens for hearing acuity.

True

False

True or False: A person with profound, bilateral sensorineural hearing loss can pass immittance screening.

True

False

The Eustachian Tube and Air Pressure in the Middle Ear

These questions will help assess your familiarity with the eustachian tube, negative middle ear pressure, P.E. tubes, additional conditions or circumstances that may affect immittance screening results, occlusion, and perforations of the eardrum.

The job of the Eustachian tube is to:

Regulate the inner ear

Ventilate the middle ear cavity and equalize air pressure in the middle ear cavity so that it is equal to that of the environment in which a person is found

Divert sound energy

Negative middle ear pressure can cause:

The eardrum to be pushed outward, into the ear canal.

The Ossicles to crumple in upon themselves.

The eardrum to be pulled inward, away from its natural or more “neutral” position.

If negative middle ear pressure in the middle ear cavity continues for a period of time, what may be eventually drawn from the mucosal lining as a result?

More oxygen

Hair cells

Fluid

The accumulation of fluid in the middle ear space is called:

Occlusion

Effusion

Ossicular Flooding

True or False: A physician determines if fluid and/or infection is present, not the screener.

True

False

Understanding Immittance Screening

These questions will help assess your familiarity with immittance screening, otoscopy, probe tip fit, and tips for obtaining and maintaining a good seal.

True or False: Immittance screening requires a response from the child and background noise will affect the screening results.

True

False

True or False: If screening an infant or toddler, you may want them to sit on a familiar lap.

True

False

It is recommended that you:

Not ask the child for permission to begin immittance screening.

Ask the child for permission to begin immittance screening.

Inform the child the immittance screening will not hurt before beginning the screening.

Otoscopy refers to what?

A field of specialty within the practice of audiology.

Visually inspecting the ear canal, its size and direction, and the eardrum with an otoscope.

A surgical procedure.

If a foreign object or drainage is visualized during otoscopy:

Note the findings and proceed with the screening.

Do not proceed with the screening and make a referral to the child’s primary care physician.

Tell the child to clean out his or her ears.

Understanding Immittance Screening Results: Tympanometry and Acoustic Reflexes

These questions will help assess your familiarity with how immittance results are derived, tympanometry and tympanograms, ear canal volume, middle ear pressure, tympanic membrane compliance, and acoustic reflexes.

Immittance screening equipment may also help determine ______________.

If any fluid in the middle ear is infected; if the inner ear is functioning properly.

If the eardrum is present; if all three Ossicles are in the correct place; if the auditory cortex is functioning properly.

If wax is occluding the ear canal; if there is a perforation of the eardrum; if ventilation tubes are working properly.

True or False: Understanding the relationship between Ear Canal Volume, Tympanic Membrane Compliance, and Middle Ear Pressure will be critical to understand immittance results.

True

False

A large Ear Canal Volume may reflect:

A perforation of the eardrum or an open P.E. tube.

That the eardrum is missing.

An abnormally large ear canal.

True or False: Values for both Middle Ear Pressure and Tympanic Membrane Compliance do not rely upon movement of the Tympanic Membrane.

True

False

True or False: For tympanograms with very low Tympanic Membrane Compliance (0.1ml or less) the absence or presence of the acoustic reflex is used to determine if the results are a pass or a refer.

True

False

Immittance Pass/Fail Criteria and Wyoming Developmental Screening Include Hearing Screening

These questions will help assess your familiarity with immittance pass/fail criteria.

Which of the following are the three components of a developmentally appropriate hearing screening for Wyoming children (ages 1-5)?

Otoscopy, Pure Tones or Otoacoustic Emissions (OAEs), Immittance

Otoscopy, Pure Tones, Otoacoustic Emissions (OAEs)

Otoscopy, Noise Makers, Immittance

Which of the following will not cause an ear canal volume to be large?

An open Pressure Equalization (P.E.) Tube

Impacted Ear Wax

A perforated eardrum

What is the acceptable range for Middle Ear Pressure to be considered a pass for Immittance screening?

+100 daPa to -250 daPa

-250 daPa to -400 daPa

+200 daPa to +100 daPa

True or False: When conducting a hearing rescreen, you only need to conduct the hearing screening component(s) that were failed.

True

False

True or False: When conducting a hearing rescreen, you only need to rescreen the ear that did not pass the previous screening(s).

True

False

True or False: If a child fails immittance and passes Pure Tones or Otoacoustic Emissions (OAEs) on two separate screenings, it is appropriate to make a medical referral.

True

False

True or False: If a child fails immittance and passes Pure Tones or Otoacoustic Emissions (OAEs) on two separate screenings, it is appropriate to make an audiological referral.

True

False

Which of the following ventilates the middle ear space and equalizes middle ear pressure?

The Ear Canal

The Eustachian Tube

The Tympanic Membrane

Another name for the ear drum is _______________.

The Cochlea

The Ear Barrier

The Tympanic Membrane

"TMC" stands for what?

Tympanic Motion Condition

Tympanic Membrane Compliance

The Mechanical Component
