A nurse is planning care for a client who is being admitted for treatment of anorexia nervosa. Which of the following interventions should the nurse include?

A. Administer methylphenidate daily: Stimulant medications like methylphenidate are not appropriate for anorexia nervosa treatment, as they can suppress appetite and worsen weight loss. They are contraindicated in clients with this disorder. B. Weigh the client twice a week: Weighing twice a week is insufficient for clients with anorexia nervosa. Daily, same-time, same-clothing weights are recommended to monitor progress and detect potential medical complications associated with malnutrition. C. Focus conversations around food at mealtimes: Focusing on food can increase anxiety and reinforce preoccupations with eating. Instead, conversations should be neutral or supportive, promoting a calm and therapeutic mealtime environment. D. Inform the client of the specific duration of meals: Setting clear expectations for meal duration helps reduce anxiety, provides structure, and supports adherence to nutritional rehabilitation. It is an effective intervention in the care plan for clients with anorexia nervosa.
