A nurse is caring for a client who reports that they have been eliminating specific foods from their diet in order to "eat clean." The nurse should identify that this is an indication of which of the following conditions?

A. Orthorexia. Orthorexia is characterized by an unhealthy obsession with eating foods that one considers healthy and the avoidance of foods perceived as unhealthy. The client's report of eliminating specific foods to "eat clean" aligns with this condition, indicating a focus on the quality of food rather than quantity. B. Pica. Pica is the compulsive consumption of non-food items, such as dirt or chalk. The client's behavior of eliminating foods does not fit this description, as they are not consuming non-nutritive substances. C. Anorexia nervosa. Anorexia nervosa is an eating disorder characterized by restrictive eating and an intense fear of gaining weight. While clients with anorexia may eliminate foods, the specific focus on "eating clean" suggests a different motivation than the fear of weight gain typically seen in anorexia. D. Rumination disorder. Rumination disorder involves the repetitive regurgitation of food, which is then re-chewed or re-swallowed, rather than the intentional avoidance of certain foods. This behavior does not relate to the client's reported actions of eliminating foods from their diet.
