A nurse is caring for a client who has a diagnosis of Cushing syndrome. After performing magnetic resonance imaging (MRI), the underlying cause of the condition is found to be hyperplasia of the adrenal glands. Which of the following lab results would the nurse anticipate with this condition?
Correct answer
C
Rationale
Low ACTH and elevated cortisol is consistent with Cushing syndrome caused by adrenal gland hyperplasia, where the adrenal glands produce excess cortisol independently of ACTH stimulation.
