A nurse is caring for a child who has Addison's disease. Which of the following actions should the nurse take?

A. Monitoring for fluid volume excess is not appropriate for Addison's disease, where there is usually fluid volume deficit due to low aldosterone levels. B. Hyperglycemia is not commonly associated with Addison's disease; instead, hypoglycemia can occur. C. A low-sodium diet is inappropriate for children with Addison's disease. They typically need extra salt due to a deficiency in aldosterone. D. Cortisol replacement therapy is essential in managing Addison's disease. Parents should be educated on how to administer and adjust the dosage in response to illness or stress.
