Final answer:
To assist an older adult client with hemianopsia who is at risk for falls, the nurse should instruct the client to scan their complete range of vision during ambulation.
Step-by-step explanation:
To assist an older adult client with hemianopsia who is at risk for falls, the nurse should include the instruction to remind the client to scan their complete range of vision during ambulation. This is important because the client's loss of lateral peripheral vision makes it difficult to detect objects on their right and left. By scanning their complete range of vision, the client can compensate for this visual deficit and potentially avoid falls.
Keeping the client's personal care items in the bathroom and securing extension cords under carpeting are not directly related to the client's specific visual deficit and fall risk. Keeping the overhead lights on in the client's bedroom while sleeping may disturb their sleep and is not necessary to address their visual deficit.
