Correct Answer is D
Explanation
Choice A rationale
Speaking loudly and into the client’s good ear is not recommended. Loud speech can be distorted and uncomfortable for individuals with presbycusis.
Choice B rationale
Using sign language is not necessary unless the client is proficient in it. Most clients with presbycusis benefit more from clear verbal communication.
Choice C rationale
Sitting by the client’s side and speaking very slowly is not as effective as speaking directly to the client in a normal, clear voice.
Choice D rationale
Speaking directly to the client in a normal, clear voice is recommended. This ensures that the client can read lips and understand the conversation better.
Correct Answer is D
Explanation
Choice A rationale
This statement is incorrect. While the tubes are designed to allow air to enter the middle ear and prevent fluid buildup, water can still enter through the tubes and potentially cause infections or other complications. Therefore, it is important to take precautions to keep water out of the ears, especially during activities like swimming or bathing.
Choice B rationale
This statement is incorrect. Tympanostomy tubes are not designed to be removed every night. They are small tubes inserted into the eardrum to allow air to enter the middle ear and prevent fluid buildup. They remain in place until they naturally fall out on their own, which typically happens within 6 to 12 months.
Choice C rationale
This statement is incorrect. The tubes do not need to be replaced every 2 years. Tympanostomy tubes usually fall out on their own within 6 to 12 months. If they do not fall out naturally, a healthcare provider may need to remove them. However, routine replacement every 2 years is not necessary.
Choice D rationale
This statement is correct. Tympanostomy tubes are designed to fall out on their own, usually within 6 to 12 months after insertion. This natural process allows the eardrum to heal without the need for additional surgical intervention.
