Answer to Question 1

ANS: A
Addison disease is caused by autoimmune mechanisms that destroy adrenal cortical cells and is more common in women. Addison disease is not due to dietary deficiency, to cancer, or to a viral infection.

Answer to Question 2

ANS: C
Polyuria occurs due to increased fluid in the vascular space, and microalbuminuria is the earliest manifestation. While glycosuria occurs due to hyperglycemia, it is not the first sign of kidney dysfunction. Decreased glomerular filtration and polyuria can occur due to changes, but neither are initial manifestations.
