A nurse is caring for a client who has bulimia nervosa. Which of the following actions should the nurse take first?

A. Observe the client during and after meals: Monitoring the client for bingeing or purging behaviors is the priority intervention because it addresses immediate safety and physical health risks, such as electrolyte imbalances. Direct observation prevents harmful behaviors and allows timely intervention. B. Refer the client to a support group for clients who have eating disorders: Referral is important for long-term psychosocial support, but it does not address immediate risk or safety concerns during meals. C. Instruct the client about effective coping strategies: Teaching coping strategies is beneficial for long-term management, but ensuring safety during meals takes precedence in the nursing process. D. Suggest that the client assist with meal planning: Involving the client in meal planning promotes autonomy and engagement in treatment, but it is not the first action when immediate monitoring is required to prevent harmful behaviors.
