A nurse is explaining congenital adrenal hyperplasia (CAH) to a group of nursing students. Which statement by a student indicates understanding of the teaching?
a. "CAH is caused by a deficiency of ACTH production."
b. "CAH is the result of an inability to syn-thesize glucocorticoids."
c. "Newborn screening provides a definitive diagnosis for CAH"
d. "The enzyme 21-alpha-hydroxylase in-creases the production of androgens."
B
CAH results from an inborn deficiency of the enzymes needed for glucocorticoid synthesis. The condition is marked by increased production of ACTH, because the pituitary attempts to enhance glucocorticoid synthesis. Newborn screening indicates a deficiency of 21-alpha-hydroxylase; if this is noted, follow-up testing must be done to confirm a diagnosis of CAH. The enzyme 21-alpha-hydroxylase increases the production of glucocorticoids. When this enzyme is deficient, androgens are produced in excess because of stimulation by ACTH.
