Answer to Question 1

C
Feedback:
Whenever blood flow or oxygenation to the nephron is decreased (due to hemorrhage, shock, heart failure, or hypotension), the hormone erythropoietin is also released from the juxtaglomerular cells. Therefore, options A, B, and D are not correct.

Answer to Question 2

A
Feedback:
It is important for this patient to understand what will happen and the changes he will see to reduce the anxiety that could occur if he didn't understand. Discuss the development of masculine characteristics as well as common adverse effects such as acne. Having the patient fast before the injection would not be necessary, nor would decreasing exercise or reducing protein intake.
