Final answer:
The client is adapting to the changes caused by age-related macular degeneration by using a magnifying glass to read and attending a support group for people with visual impairments.
Step-by-step explanation:
The nurse should ID the statement "I've started using a magnifying glass to read" as an indication that the client is adapting to the changes caused by age-related macular degeneration. Using a magnifying glass can help the client compensate for their decreased vision and improve their ability to read. This adaptation shows that the client is proactive in finding solutions to their visual impairment. Attending a support group for people with visual impairments is also a positive indication that the client is adapting to the changes. By participating in a support group, the client can find emotional support and practical advice for coping with their condition.
