Answer-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 - Answer-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 - Answer-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 - Answer-An amplifier problem
Germicidal wipes are an example of - Answer-Disinfectant
4 modes of transmission - Answer-Contact, Indirect contact, Droplet, Vehicle,
Airborne, vectorborne
Contact - Answer-Directly infected by the host
, Indirect contact - Answer-Touching something contaminated by an infected person.
Surfaces or objects
Droplet - Answer-transmission via airborne droplets
Vehicle - Answer-Transmitted by contaminated substances such as water, food,
blood or bodily substance
Airborne - Answer-Droplet or neucli or dust transmission
Vectorborne - Answer-Animals or insects carries pathogen

Audiometric zero - Answer-The average softest intensity that someone with normal
hearing can detect
Tympanometry - Answer-Measures middle ear function and compliance is also
known as imittence audiometry
Acoustic Reflex - Answer-Middle ear muscle reflex, tympanometer is used to
measure activity of stapedius muscle
TPP - Answer-Tympanometric peak pressure- 0.6-144cc

threshold - Answer-Otosclerosis
A large dip at 6000Hz in ONE ear only with a positive tone decay is an indicative of -
Answer-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 - Answer-Impedance audiometery
What programmable adjustment would be BEST to control loud sharp sounds -
Answer-Increase the compression ratio
During otoscopic inspection what is NOT a consideration for earmold selection -
Answer-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 - Answer-Receiver tubing pushed in
