IHS ANSWERS AND QUESTIONS SET A+
✔✔What hearing instrument component is a transducer? - ✔✔Telecoil
✔✔A patient's case history reveals unilateral left ear hearing loss of more than 10 years,
recent ear pain, and discharge for approximately 2 months. Otoscopy in the left ear
shows that the TM is reddish in color and the canal is very moist. In addition, an odor is
detected. What should be done next? - ✔✔Explain the otoscopic findings and
immediately refer the patient to their physician of choice
✔✔Why should verification be completed at the fitting visit? - ✔✔**To demonstrate to
the patient that their hearing instruments are functioning properly**
✔✔What criteria determines that the plateau has been reached during masked testing?
- ✔✔When effective masking is applied without a shift in the TE threshold
✔✔A patient with arthritis, macular degeneration, and a bilateral moderate to severe
hearing loss wears glasses and uses oxygen with tubes that go over their ears. What
style of hearing instruments should be recommended? - ✔✔ITE
✔✔A patient reported significant concerns about hearing effectively during an important
meeting they have scheduled for the next day. An audiometric assessment
demonstrated bilateral mixed hearing loss. Otoscopy was then completed and revealed
that only one quadrant of the TM was visible due to copious cerumen in each ear canal.
Demonstration binaural RIC/RITE hearing instruments were provided to help with the
meeting, and a follow-up appointment was scheduled for the next day. WHat should
have been done differently in this situation? - ✔✔Otoscopy should have been performed
before audiometric testing
✔✔What is the difference between IA and crossover? - ✔✔IA involves intracranial
sound transmission. Crossover is the intensity of the sound that can be heard in the
NTE
, ✔✔ Why is masking used - ✔✔to eliminate the non-test ear from participation in the
measurement of hearing thresholds in the test ear
✔✔Which combination of test data can influence the classification and degree of
hearing loss? - ✔✔**PTA & WRS**
✔✔What should be done if a hearing healthcare professional makes a home visit to
make ear impressions but has forgotten an otoscope? - ✔✔Return to the office for an
otoscope.
✔✔What audiometric condition requires a medical referral? - ✔✔Symmetrical
sensorineural HL with asymmetrical WRS
✔✔A patient complains that the refrigerator and furnace fans sound annoying. Which
feature should be adjusted? - ✔✔Expansion
✔✔A patient is very interested in connectivity and does not want to wear a gateway
device while speaking hands-free on the phone & listening through their hearing
instruments. What wireless technology should be recommended? - ✔✔2.4 GHz
(Bluetooth)
✔✔A patient has an unaidable single-sided conductive HL and reports an unsuccessful
trial with a CROS fitting. What should be recommended? - ✔✔Refer for a BAHA
consultation.
✔✔What hearing aid settings should be used to evaluate hearing instrument
electroacoustical performance prior to the fitting? - ✔✔Test mode with FOG
✔✔What strategy should family members be encouraged to use when talking with their
loved ones who wear hearing instruments? - ✔✔Face each other when speaking
✔✔What percent of alcohol must an effective hand sanitizer contain? - ✔✔60%
✔✔When selecting an appropriate hard earmold material for a patient with severe
allergies, which material should be ordered? - ✔✔Polyethylene
✔✔What is considered the single most significant factor in hearing instrument
acceptance and use? - ✔✔Post-fitting care
✔✔What is the first thing to do after completing post-fitting validation measures? -
✔✔Discuss the differences between the patient's pre-fitting and post-fitting validation
measures with the patient?
