Q: A hearing healthcare professional adds wind baffles to a patient's/client's ITC hearing instruments. One week later, the patient/client returns to the office and reports that the baffles helped with the wind noise; however, the patient/client is now experiencing external feedback.<br>What should the hearing healthcare professional do with the wind baffles?
- turn them so they face upward
- turn them so they face forward
- cut them to cover less of the microphone
- remove them and reseal the microphone
A: turn them so they face upward

Q: A patient/client complains that the hearing instrument works intermittently.  After initial inspection, the hearing healthcare professional squeezes and taps on the case.<br>Which problem does the hearing healthcare professional likely suspect?
- a receiver problem
- a battery problem
- an amplifier problem
- a wiring problem
A: a wiring problem

Q: A new patient/client has been wearing hearing instruments for six months and complains that background noise hurts both ears.  The hearing healthcare professional connects the hearing instruments to a computer and discovers that they have been worn for 190 hours.<br>Which step should the hearing healthcare professional take first?
- reduce high frequency amplification
- reduce overall gain
- encourage the patient/client to wear the instruments more consistently
- determine the environments in which the aids are being worn
A: reduce overall gain

Q: A patient/client has been wearing a set of canal aids for three years.   The patient/client reports that co-workers have noticed an irritating whistle coming from the hearing instruments.  <br>What should the hearing healthcare professional try first?
- put lamb’s wool in the receiver port
- have the aids recased
- check the fit of the aids
- block the vent
- build up the canal
- check the shell for cracks
A: check the fit of the aids

Q: A patient/client reports that a BTE hearing instrument is dead. The hearing healthcare professional conducts a listening check with the earhook removed and finds that the hearing instrument operates properly. What is the likely cause of the patient's/client's problem?
- crack in tubing
- moisture in tubing
- disarticulated tubing
- excessively dry tubing
A: moisture in tubing

Q: A patient/client reports to a hearing healthcare professional that the hearing instrument "sounds funny". To troubleshoot the issue, the hearing healthcare professional performs a listening check and otoscopy. The findings for both are unremarkable. What should the hearing healthcare professional do next?
- Perform tympanometry
- Perform audiometric re-evaluation
- Refer patient/client for ENT evaluation
- Perform electro-acoustic analysis
A: Perform electro-acoustic analysis

Q: A patient/client has worn new BTE style aids for one week and reports that the right hearing aid stopped working after 4 days. The hearing healthcare professional conducts a test/box analysis and finds s distortion of less than 5% at all measured frequencies and no reduction of the gain or output. The hearing aid circuit drain meets specifications.<br>What should the hearing healthcare professional do?
- re-program the hearing aid for additional gain
- install a damper in the earhook
- inspect the tubing and remedy any problems
- re-program the hearing aid for additional output
A: inspect the tubing and remedy any problems

Q: Since a recent earmold tube replacement, your patient/client states that their BTE is no longer fitting comfortably.  You observe that the patient/client earmold is inserted properly; however, the BTE does not appear to be properly placed behind the pinna. To resolve this complaint you would determine if:
- the tube length was changed during tube replacement
- the earmold was cracked during tube replacement
- the earhook was damaged during tube replacement
- the hearing aid was cracked during tube replacement
A: the tube length was changed during tube replacement

Q: Your patient/client reports being pleased with their hearing instrument performance and has returned to your clinic for their periodic instrument clean and check.  When replacing the mic cover/windscreen of a hearing instrument you wish to make certain that the hearing instrument continues to perform at its electro-acoustic level prior its replacement. What would you do to make this determination?
- a biologic listening check
- ask the patient/client "how it sounds"
- a test box analysis
- a fast-Fourier transform analysis
A: a test box analysis
