Answer to Question 1

A
Feedback:
The reninangiotensin system causes vasoconstriction to improve blood flow to the fragile nephrons. Baroreceptors are not found in the renal artery. Increased sweating is not a reflex reaction to increased total body water. ADH is released in response to decreased blood volume and increased osmolarity.

Answer to Question 2

A
Feedback:
Because of the effects of androgens on epiphyseal closure, children should be closely monitored with hand and wrist radiographs before treatment and every 6 months after treatment. The other options are also adverse effects and require monitoring but are not as serious as premature epiphyseal closure.
