Answer to Question 1

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

Answer to Question 2

D
Vitamin K is administered, because the neonate's intestines do not contain normal bacterial flora. It is administered to all neonates. Vitamin K does not facilitate digestion or impact on platelet levels.
