A nurse is caring for a client who has anorexia nervosa and overexercises to avoid gaining weight. Which of the following nursing actions should the nurse take?

A. Restrict the client from being weighed: Clients with anorexia nervosa require monitoring of their weight to assess physical status and treatment progress. However, blind weighing (where the client stands back-to-the-scale) is often used so the client doesn't fixate on the number. B. Reprimand the client about the potential damage that has occurred due to overexercising her body: Reprimanding is non-therapeutic. It is punitive and judgmental, which damages the nurse-client relationship and increases the client's anxiety and defensiveness. C. Praise the client for looking at herself in a mirror: Clients with anorexia often have body dysmorphia (distorted body image). Focusing on appearance or mirror-checking can reinforce their obsession with body shape and size. D. Ask the client to agree to talk to a nurse whenever she feels the urge to exercise: This intervention uses behavior modification and limits setting. The goal is to replace the maladaptive coping mechanism (compulsive exercising to purge calories) with a healthy coping mechanism (verbalizing feelings and anxiety). This empowers the client to recognize triggers and seek support.
