Final answer:
A client with normal hearing through 1000 Hz and moderate sensorineural hearing loss at higher frequencies likely requires skeleton molds made of lucite with a Select-A-Vent (SAV), matching option B in the provided choices.
Step-by-step explanation:
For a client who has normal hearing through 1000 Hz with a moderate sensorineural hearing loss at the higher frequencies, the selection of earmolds is crucial to ensure effective hearing aid performance. While a non-occluding (CROS) mold might be appropriate for cases with one-sided hearing loss, it is not indicated here. Similarly, the use of no mold or tubing would neglect the specific needs of this hearing profile.
A skeleton mold, made of lucite with a Select-A-Vent (SAV), provides some occlusion to enhance the low-frequency sounds the client can hear naturally while allowing for the adjustment of venting to control the amount of amplified sound escaping from the ear canal, which is beneficial for those with high-frequency hearing loss. Therefore, the most suitable choice for earmolds in this scenario would be option B: skeleton molds, lucite, SAV.
