Answer to Question 1

B
Feedback:
Releasing hormones or factors are chemicals released by the hypothalamus into the anterior pituitary to stimulate the release of anterior pituitary hormones. The releasing hormone does not activate a hormone but stimulates its production. It does not stimulate the glands (hypothalamus or pituitary) but rather stimulates release of an anterior pituitary hormone.

Answer to Question 2

C
Feedback:
First determine the number of units per mL = 25,000 units/250 mL = 100 units/1 mL. Next use the ratio and proportion method to determine the number of milliliters needed to supply 600 units/h. 100 units/1 mL = 600 units/X. Cross-multiplying yields 6 mL needed every hour to supply the required dose.
