When a medical examiner, or a trained assistant, documents the audiometric test results on the Medical Examiner’s Report, they must convertISO units to ANSI units by:
  1. Subtracting 10 dB from ISO for the test performed at 500 Hz.
  2. Subtracting 10 dB from ISO for the test performed at 1,000 Hz.
  3. Subtracting 14 dB from ISO for the test performed at 1,000 Hz.
  4. Subtracting 8.5 dB from ISO for the test performed at 1,000 Hz.
Explanation
Answer: B - Subtracting 10 dB from ISO for the test performed at 1,000 Hz.

This is the correct answer because according to FMCSA guidelines,when recording hearing test results according to the American National Standards Institute (ANSI), the following decibels (dB) are subtracted from the International Organization for Standardization (ISO) hearing loss values: 14 dB for 500Hz, 10 dB for 1,000Hz, and 8.5 dB for 2,000Hz.
