Answer to Question 1

ANS: D
Oxytocin functions near the end of labor to enhance effectiveness of contractions, promote de-livery of the placenta, and stimulate postpartum uterine contractions, thereby preventing exces-sive bleeding. Aldosterone regulates water balance. Cortisol helps protect from stress. Prolactin assists with milk production.

Answer to Question 2

ANS: B
The zona glomerulosa, the outer layer, constitutes about 15 of the cortex and primarily produc-es the mineralocorticoid aldosterone. The zona glomerulosa is not associated with sodium, potas-sium, or acid production.
