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 C
Explanation
Choice A rationale
Applying cool compresses can help reduce swelling and discomfort, but it is not the primary instruction for a client scheduled for retinal detachment surgery.
Choice B rationale
Eye drops to constrict the pupils are not typically prescribed for retinal detachment surgery. The focus is on preventing further detachment and ensuring proper healing.
Choice C rationale
Restricting head movement is crucial to prevent further detachment of the retina and to promote proper healing after surgery. The client should be instructed to avoid sudden or excessive head movements.
Choice D rationale
Keeping both eyes patched is not necessary and may cause unnecessary discomfort and disorientation for the client.
