  1. 1A dispenser is scheduling the annual calibration check for the clinic audiometer. What interval does California law require?

    1. A. At least annually
    2. B. Every six months
    3. C. Every two years
    4. D. Only after repair

    Answer: A

    Explanation: California BPC §2538.11 says calibration shall be checked "at least annually"; the annual schedule complies.

    Reference: Codes Display Text — § 2538.11(a)

  2. 2A client reports new dizziness and one-sided tinnitus. What is the best case-history action?

    1. A. Document onset, course, laterality, and associated symptoms
    2. B. Record only the chief complaint
    3. C. Defer symptom questions until after fitting
    4. D. Ask only about prior hearing-aid brand

    Answer: A

    Explanation: The California outline specifies "Knowledge of techniques to gather and assess client symptoms." Onset, course, laterality, and associated symptoms make the history clinically useful.

    Reference: Written Examination Outline (Tasks & Knowledge) — K7, page 1

  3. 3An outer-ear abnormality is seen during inspection. What is the appropriate consequence for the assessment plan?

    1. A. Continue with routine air-conduction testing before documenting it
    2. B. Modify only the client response method and begin threshold testing
    3. C. Consider medical or audiologic referral before proceeding
    4. D. Perform real-ear verification before deciding whether referral is needed

    Answer: C

    Explanation: The California outline requires "Knowledge of effects of ear pathologies on hearing loss." The dispenser recognizes the abnormality and considers referral rather than diagnosing its systemic cause.

    Reference: Written Examination Outline (Tasks & Knowledge) — K13, page 1

  4. 4Which assessment result most directly supports recommending hearing-aid amplification?

    1. A. Documented hearing loss with communication needs
    2. B. Normal hearing without concerns
    3. C. A device color request alone
    4. D. An expired warranty

    Answer: A

    Explanation: The official outline requires using "assessment results to determine amplification" recommendations. Documented hearing loss plus communication need supports amplification.

    Reference: Written Examination Outline (Tasks & Knowledge) — K74, page 5

  5. 5What is the main purpose of an ear impression?

    1. A. Create a custom coupling model
    2. B. Measure speech recognition
    3. C. Calibrate an audiometer
    4. D. Set wireless pairing

    Answer: A

    Explanation: The Board outline assesses knowledge of "how to take and evaluate an ear impression." The impression creates the anatomical model needed for a custom coupling.

    Reference: Written Examination Outline (Tasks & Knowledge) — Section 5 and K93, page 7

  6. 6Before placing a new aid on a client, what should be verified?

    1. A. Advertising copy
    2. B. Function and order consistency
    3. C. Renewal date
    4. D. Insurance deductible

    Answer: B

    Explanation: The Board task says, "Check hearing aids to verify functionality" and consistency with the order before fitting.

    Reference: Written Examination Outline (Tasks & Knowledge) — T41 and K131, page 7

  7. 7Which setup is essential when comparing aided and unaided sound-field results?

    1. A. Air-conduction earphones for one condition only
    2. B. A bone oscillator at a changing placement between runs
    3. C. A probe tube substituted for the sound-field stimulus
    4. D. Consistent calibrated loudspeaker geometry

    Answer: D

    Explanation: The California outline expressly requires "Knowledge of methods to perform sound field testing." Consistent calibrated loudspeaker geometry is necessary for a meaningful aided-versus-unaided comparison.

    Reference: Written Examination Outline (Tasks & Knowledge) — K30, page 2

  8. 8Both aids pass listening and electroacoustic checks, but hearing worsened. What is assessed next?

    1. A. Whether wax or moisture blocks the sound outlet
    2. B. Whether depleted batteries caused intermittent output
    3. C. Whether wireless pairing caused the reported difficulty
    4. D. Whether the client's hearing has changed since prior testing

    Answer: D

    Explanation: The Board outline requires techniques to "differentiate changes in client hearing from malfunction of hearing aid." Because both aids pass device checks, reassessing hearing is next.

    Reference: Written Examination Outline (Tasks & Knowledge) — K197, page 11

  9. 9Which immediate strategy best improves conversation in a noisy room?

    1. A. Move closer and reduce competing background noise
    2. B. Face the speaker in better light to improve visual cues
    3. C. Use an assistive listening device for a distant talker
    4. D. Ask the speaker to rephrase a message that was misunderstood

    Answer: A

    Explanation: The NIDCD advises, "Turn off or turn down the volume of background noise." Moving closer while reducing that noise improves access to speech.

    Reference: Age-Related Hearing Loss (Presbycusis) — Tips for talking with someone who has hearing loss

  10. 10During the daily equipment check, a known listener shows a 10 dB threshold deviation. What calibration response is indicated?

    1. A. Continue and recheck monthly
    2. B. Arrange acoustic calibration
    3. C. Replace only the earphones
    4. D. Perform exhaustive calibration immediately

    Answer: B

    Explanation: OSHA states, "Deviations of 10 decibels or greater require an acoustic calibration."

    Reference: 1910.95 - Occupational noise exposure. | Occupational Safety and Health Administration — § 1910.95(h)(5)(i)
