Answer to Question 1
ANS: C
The primary function of increased vascular volume is to transport oxygen and nutrients to the fetus via the placenta. Preventing maternal and fetal dehydration is not the primary reason for the increase in volume. Assisting with pulling metabolic wastes from the fetus for maternal excretion is one purpose of the increased vascular volume. Renal plasma flow increases during pregnancy.
Answer to Question 2
ANS: C
She has had four pregnancies, including the current one (gravida 4). She had two pregnancies that terminated after 20 weeks (para 2). The pregnancy that terminated at 8 weeks is classified as an abortion. Because she is currently pregnant, she is classified as a gravida 4. Gravida 4 is correct, but she is para 2; the pregnancy that was terminated at 8 weeks is classified as an abortion. Because she is currently pregnant, she would be classified as a gravida 4, not 3.
