The nurse is using a Snellen chart to assess a client’s visual acuity. From what distance should the client be positioned, and what line should they attempt to read to be considered as having 20/20 vision?

In the audiogram above, identify where masking is needed (yes/no) for right BC and what the initial presentation level should be (assume supra-aural headphones). If no masking is needed, write N/A. Right Frequency  Masking needed?   Starting level 4000 Hz        [BLANK-1]                           [BLANK-2]

In the audiogram above, identify where masking is needed (yes/no) for right BC and what the initial presentation level should be for plateau masking. Assume insert earphones. If no masking is needed, write N/A.
