What statement indicates a client needs additional instruction regarding the care of new hearing aids?

The statement indicating a client needs additional instruction regarding the care of new hearing aids is the one that mentions using alcohol wipes for cleaning. Cleaning hearing aids is important for maintenance and hygiene, but using alcohol wipes is not recommended as they can be too harsh and potentially damage the hearing aids. The materials of hearing aids are often sensitive to strong chemicals, and it's better to use a soft, dry cloth or a cleaner specifically designed for hearing aids.

Using appropriate cleaning techniques will help ensure the longevity and functionality of the devices while preventing any potential damage caused by improper cleaning methods. The other statements reflect advisable practices for hearing aid care, such as avoiding hairspray to prevent buildup, changing batteries regularly to ensure optimal performance, and understanding that some whistling may occur as a normal acoustic phenomenon in certain situations.
