Vascular volume increases by 40 to 60 during pregnancy to:
 
  a. Compensate for decreased renal plasma flow.
  b. Provide adequate perfusion of the placenta.
  c. Eliminate metabolic wastes of the mother.
  d. Prevent maternal and fetal dehydration.

Question 2

The capacity of the uterus in a term pregnancy is how many times its prepregnant capac-ity?
 
  a. 100
  b. 200
  c. 300
  d. 500

Answer to Question 1

B
The primary function of increased vascular volume is to transport oxygen and nutrients to the fetus via the placenta.
Renal plasma flow increases during pregnancy.
Assisting with pulling metabolic wastes from the fetus for maternal excretion is one purpose of the increased vascular volume.
This is not the primary reason for the increase in volume.

Answer to Question 2

D
The prepregnant capacity of the uterus is about 10 ml, and it reaches 5000 ml (5 L) by the end of the pregnancy, which reflects a 500-fold increase.
100, 200, and 300 are too small for a normal pregnancy.
