Answer to Question 1

D
The only positive signs of pregnancy are auscultation of fetal heart tones, visualization of the fetus by ultrasound, and fetal movement felt by the examiner.
Fetal movement is a presumptive sign of pregnancy.
Amenorrhea is a presumptive sign of pregnancy.
Breast changes are a presumptive sign of pregnancy.

Answer to Question 2

B
When blood volume expansion is more pronounced and occurs earlier than the increase in red blood cells, the woman will have physiologic anemia, which is the result of dilution of hemoglobin concentration rather than inadequate hemoglobin.
Inadequate intake of iron may lead to true anemia.
If the woman does not take an adequate amount of iron, true anemia may occur when the fetus pulls stored iron from the maternal system.
There is an increases production of erythrocytes during pregnancy.
