Sodium; Calcium; Potassium

Answer to Question 2

A
Feedback:
Confirming the diagnosis of adrenocortical insufficiency requires a short plasma corticotropin (ACTH) stimulation test. The examiner administers corticotropin in the morning, and a subnormal blood cortisol level in the morning and afternoon confirms the diagnosis. CRH is a precursor to ACTH, and would not be directly affected. Cushing's disease is adrenocortical excess, with high cortisol levels.
