Final answer:
The nurse should identify a decrease in urine cortisol levels as a positive outcome of the treatment for Cushing's disease.
Step-by-step explanation:
The nurse should identify a decrease in urine cortisol levels as a positive outcome of the treatment for Cushing's disease. Cushing's disease is characterized by the hypersecretion of glucocorticoids, primarily cortisol, in the body. Treatment aims to reduce excessive cortisol levels, so a decrease in urine cortisol levels indicates that the treatment is effective.
Decreased urine cortisol levels are a positive outcome because it means that the medication or treatment is successfully reducing the excess cortisol production in the body. This is a desired result because elevated cortisol levels can cause various health issues related to Cushing's disease, such as hyperglycemia and obesity.
