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

A. Teach the parents about cortisol replacement therapy: Addison's disease involves insufficient production of cortisol, and lifelong cortisol replacement therapy is essential for managing the condition. Educating the parents about this treatment is crucial. B. Monitor the child for fluid volume excess: Addison's disease typically leads to fluid volume deficit, not excess, due to decreased aldosterone levels. The child should be monitored for dehydration, not fluid overload. C. Place the child on a low-sodium diet: Children with Addison's disease often require a higher sodium intake due to the lack of aldosterone, which helps retain sodium. A low-sodium diet is not recommended. D. Discuss the manifestations of hyperglycemia with the parents: Addison's disease usually results in low blood sugar due to insufficient cortisol production. Hyperglycemia is not a typical concern in this condition.
