Answer to Question 1

C
Feedback:
When the hypothalamus senses a need for a particular hormone, it secretes TRH directly into the anterior pituitary. Other options, therefore, are incorrect.

Answer to Question 2

C
Feedback:
To determine amount to prepare: 500 mg/1 mL = 250 mg/X. Cross-multiply to determine the nurse will prepare 0.5 mL.
