Which is an appropriate outcome for the nursing diagnosis of Body Image Disturbance for a client with anorexia nervosa?

The correct answer is 'The client verbalizes her body size accurately.' For clients with anorexia nervosa, body image disturbance is a common issue where they perceive themselves inaccurately. Verbalizing her body size accurately indicates progress towards correcting this distorted self-perception. Choices A, B, and D are incorrect because they do not directly address the distorted body image perception seen in clients with anorexia nervosa. Choice A focuses on knowledge of a maintenance diet, which is unrelated to body image perception. Choice B involves assertiveness with family, which is more related to family dynamics. Choice D addresses control of obsessive behaviors, which is not directly related to correcting the distorted body image perception.
