Final answer:
The proper summary statement is 'It seems like you're struggling with your body image and feeling overweight,' which accurately condenses the client's concerns about body image and fear of weight gain.
Step-by-step explanation:
In addressing a nurse's use of summarizing when counseling an adolescent with anorexia nervosa, the correct therapeutic response that demonstrates summarizing is: "It seems like you're struggling with your body image and feeling overweight." This response encapsulates the client's feelings about their body and their fear of weight gain, acknowledging the key elements of the situation succinctly. Summarizing is a therapeutic communication technique used to reflect understanding and to encapsulate and clarify the main points the client has expressed.
