The nurse is caring for a client with anorexia nervosa who states, "I feel powerless when I gain weight." Which problem should the nurse identify as a priority?

A. Risk for fluid and electrolyte imbalance: While important, this risk is secondary to the immediate physiological consequences of insufficient nutrition. Electrolyte imbalances often develop as a result of malnutrition and require close monitoring. B. Disturbed body image related to loss of control: Body image disturbance is central to anorexia nervosa, but it does not pose an immediate threat to life. Psychological interventions are essential but follow stabilization of physical health. C. Imbalanced nutrition less than body requirements: Inadequate nutrition directly threatens physiological stability, affecting cardiovascular, gastrointestinal, and endocrine function. Restoring adequate nutrition is the highest priority to prevent life-threatening complications such as organ failure or severe electrolyte disturbances. D. Impaired coping related to excessive physical activity: Excessive exercise may worsen malnutrition and stress, but it is secondary to the urgent need to correct nutritional deficits and stabilize the client’s physical condition.
