During an initial interview at a clinic, a young client states that there is nothing wrong with the client. Which would indicate to the nurse that this client might have anorexia nervosa?

Anorexia nervosa is characterized by a persistent restriction of energy intake leading to significantly low body weight, an intense fear of gaining weight, and a distorted perception of body shape or size. A hallmark of the disorder is anosognosia, the physiological lack of insight into the illness, which explains why the client may insist "nothing is wrong" despite being in a state of physical starvation. Rationale: A. Clients with anorexia nervosa typically have a very low self-concept that is inextricably tied to their weight and body shape. Their sense of self-worth is often fragile and dependent on their perceived success at restricting food intake, rather than a genuine positive self-image. B. Episodes of overeating followed by weight gain are more characteristic of Binge Eating Disorder. Although those with the binge-purge subtype of anorexia may have episodes of overeating, the defining feature of anorexia nervosa remains the significantly low body weight, which distinguishes it from Bulimia Nervosa, where the client is often at a normal or near-normal weight. C. Severe weight loss resulting from self-imposed starvation is the primary clinical indicator. Even when emaciated, the client may view themselves as overweight. The nurse must look for physical cues such as lanugo (fine hair growth), bradycardia, and amenorrhea, as the client will likely minimize or deny the severity of their dieting habits. D. This disorder is characterized by cognitive rigidity and perfectionism, rather than flexibility. Clients often adhere to strict, ritualistic eating patterns and food rules. Spontaneity is usually avoided because it represents a loss of control over their environment and caloric intake.
