Answer to Question 1

ANS: A
Although urinary output stays fairly constant over a wide range of arterial pressures, it is severely reduced if the renal arterial pressure drops below 75 mm Hg.

Answer to Question 2

ANS: B
PPV redistributes blood inside the kidneys, which may be an important factor in the changes that occur in kidney function.
