The physiology instructor explains that the nephrons are fragile and require a constant supply of blood and oxygen. What compensatory mechanisms work to maintain this supply?

A) The reninangiotensin system, causing vasoconstriction
B) Baroreceptor monitoring of the renal artery
C) Increased sweating when total water volume becomes too great
D) Antidiuretic hormone (ADH) release in response to increased blood volume or decreased osmolarity

Question 2

A child in renal failure is taking androgens to promote red blood cell production and is seen in the clinic every other month. What adverse drug effect would the nurse monitor for with this child?

A) Epiphyseal closure
B) Acne
C) Skin color
D) Weight gain

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.
