- lower crossover
- increase low frequency gain
- counsel patient/client about coping strategies
- filter the vent with lamb's wool
A: lower crossover

Q: A 62-year old male musician with a bilateral symmetrical flat loss, which appears sensorineural in nature, is currently wearing a single channel programmable ITE instrument on his left ear. He wants to upgrade but is highly critical of all hearing instruments due to his dissatisfaction with his current one.  In counseling with the patient/client you will likely discover that:

1. he has good directional ability with current fitting.

2. he has trouble understanding in noise.
3. music sounds dull to him.
4. re-programming his current instrument will probably lead to satisfaction.
- 1, 2, and 3 are correct
- 1 and 3 are correct
- 2 and 3 are correct
- 4 only is correct
- 1, 2, 3, and 4 are all correct.
A: 2 and 3 are correct

Q: The patient/client is a 34-year old male who presents at the clinic with "serious hearing loss".  He states that he is HIV positive and is being treated with the "cocktail".  It has caused severe hearing loss, bilaterally.  Audiometric data indicate a severe-to-profound mid-to-high frequency sensorineural loss. His binaural word discrimination scores are worse than his best monaural score.  In addition, his SRT is poorer than his speech frequency averages by about 10 dB. The hearing instrument specialist should:<br>1. Wash the hands before and after working with the patient's ears.<br>2. Wear latex gloves for the protection of the patient/client and others.<br>3. Clean headphone cushions, immittance probe tips, specula and earlight tips with viricide after use.<br>4. Inform the factory (at the time of order) to use Infection Control Procedures when working with the impression.

Q: The nursing home director gradually lost hearing over a number of years and decided it was time to get hearing instruments.  She had observed many of the nursing home residents having difficulties with their hearing instruments “whistling”.  She knew that was due to poor fitting instruments because she had been told by someone that “hearing instruments “whistle” if they don’t fit correctly”.  She told her dispenser that if her hearing aids “whistled” she wouldn’t use them (see audiogram 1510).  The dispenser should NEXT:
- fit CIC instruments.
- explain that there are many ways to control feedback so she shouldn’t worry about it.
- fit BTE instruments with IROS earmolds to best accommodate the high frequency loss.
- explain that feedback is normal and a problem with all hearing instruments.
- explain the potential for feedback with different types of fittings.
A: explain the potential for feedback with different types of fittings.

Q: The patient/client, a 52-year-old computer executive comes in with a newspaper advertisement promising a hearing instrument that will let him hear perfectly, understand the small voice of his grandchild in noise, and handle the background noise at meetings.  These claims:

- are reasonable expectations.
- are unreasonable expectations.
- are reasonable for mild hearing loss.
- are true for sensorineural hearing loss.
A: are unreasonable expectations.

Q: Selective amplification procedures assume that differences:<br>1. in hearing aids exist.<br>2. in amplification for patients exist.<br>3. can be measured.<br>4. are often negligible.
- 1, 2, and 3 are correct
- 1 and 3 are correct
- 2 and 4 are correct
