A nurse is teaching a client about how to use her new hearing aids. Which of the following statements should the nurse identify as an indication that the client needs further instruction?

Choice A reason: Cleaning hearing aids with alcohol wipes is incorrect as alcohol can damage the hearing aids. The proper cleaning method involves using a soft, dry cloth or a cleaning kit specifically designed for hearing aids. This statement indicates a need for further instruction as it suggests a misunderstanding of proper hearing aid maintenance. Choice B reason: Hearing aids may whistle (feedback) when cupped by the hand. This is a normal occurrence and indicates that the hearing aids are functioning. This statement does not indicate a need for further instruction. Choice C reason: Not using hairspray while wearing hearing aids is correct, as hairspray can damage the devices. This statement reflects proper understanding and does not indicate a need for further instruction. Choice D reason: Changing the batteries once a week is a typical practice, though the frequency may vary based on usage and battery type. This statement shows a correct understanding of hearing aid maintenance and does not indicate a need for further instruction.
