  A)
  It removes water from the filtrate and returns it to the vascular compartment.
  B)
  It lessens the amount of fluid entering the glomerulus.
  C)
  It leads to the production of dilute urine.
  D)
  It causes tubular cells to lose their water permeability.

Question 2

Answer to Question 1

Ans:
A

Feedback:

ADH maintains extracellular volume by returning water to the vascular compartment. This leads to the production of concentrated urine by removing water from the tubular filtrate. In exerting its effect, ADH produces a marked increase in water permeability in tubular cells.

Answer to Question 2

Ans:
C

Feedback:

In contrast to hypovolemic shock, in which the heart rate is faster than normal and the skin is cold and clammy, a person in neurogenic shock is likely to have a slower than normal heart rate and dry, warm skin. Fainting due to emotional causes is a transient form of neurogenic shock, while increased thirst is an early sign of hypovolemic shock.
