IHS ILE Study Guide 2022 with complete solution
What two actions MUST a hearing healthcare professional perform before testing
an existing patients hearing
Clean hands in view of patient and clean or replace speculum from otoscope
How does osteoma present
Bony growth in external auditory canal
What should a hearing healthcare professional do prior to administering a speech
reception threshold test
Familiarize patient with the word list
A 36- year old female restaurant worker with history of hearing loss reports she is
unable to hear as well as she did 2 years ago testing reveals moderate conductive
loss what is a likely cause of the patients change in hearing
Otosclerosis
What portion of the ear contains sebaceous glands
Outer portion of external auditory canal
Which factor will affect patients acceptance in hearing instruments?
Cosmetic preferences
Why should otoblock be placed beyond second bend of ear canal
Results in complete impression of the canal
What validation method can be effectively performed in a sound field
environment
NU-6
A hearing health care professional is counseling a patient about expectations of
amplification what information should the hearing healthcare professional
include in this therapy
Outside factors that can hinder hearing
A patient has been using an ITC hearing instrument for approx 16 mos the patient
has a new job that requires use of telephone with a headset
Add an amplifier to existing phone
A patient complains that the hearing instrument works intermittently After initial
inspection the hearing healthcare professional squeezes and taps on the case
What is the suspected problem
An amplifier problem
Germicidal wipes are an example of
Disinfectant
4 modes of transmission
Contact, Indirect contact, Droplet, Vehicle, Airborne, vectorborne
Contact
Directly infected by the host
Indirect contact
Touching something contaminated by an infected person. Surfaces or objects
Droplet
transmission via airborne droplets
Vehicle
, Transmitted by contaminated substances such as water, food, blood or bodily
substance
Airborne
Droplet or neucli or dust transmission
Vectorborne
Animals or insects carries pathogen
Characteristics of tympanic membrane
Pinkish- gray in color oval shaped
Audiometric zero
The average softest intensity that someone with normal hearing can detect
Tympanometry
Measures middle ear function and compliance is also known as imittence audiometry
Acoustic Reflex
Middle ear muscle reflex, tympanometer is used to measure activity of stapedius muscle
TPP
Tympanometric peak pressure- 0.6-144cc
ECV
Ear canal volume +200 to 400 mH2o or dapa
The most common cause of sudden loss of of hearing at 4000Hz is
Acoustic trauma
What condition would not be a concern in establishing pure tone air conduction
threshold
Otosclerosis
A large dip at 6000Hz in ONE ear only with a positive tone decay is an indicative
of
A possible retrocochlear tumor
A patient who has worn hearing aids for a long time reports his ears are stopped
up he recently had a cold, What will give the MOST information about this
patients complaint
Impedance audiometery
What programmable adjustment would be BEST to control loud sharp sounds
Increase the compression ratio
During otoscopic inspection what is NOT a consideration for earmold selection
Compliance of tympanum
A patient comes in complaining that his ITC aids were working fine until he had
them cleaned now they are week and feeding back What is most likely the cause
of the problem
Receiver tubing pushed in
A patient who has had a radical mastoidectomy has been referred to your office
for a new earmold Physician is urging caution due to short canal What would be
true about this patient
Multiple otoblocks may be needed, Careful placement of otoblock is needed
DSP is
digital signal processing
What is the test to determine the effectiveness of directional microphones
