Answer to Question 1

ANS: C
Amniocentesis is the most common method to retrieve fetal cells for chromosome analysis. Viable fetal cells are sloughed off into the amniotic fluid, and when a sample is taken, they can be cultured and analyzed. It is difficult to obtain a sample of the fetal blood. It is a high-risk situation for the fetus. Fetal cells are not present in the maternal urine or blood.

Answer to Question 2

ANS: B
As the fetus descends toward the pelvic inlet (dropping), the woman notices that she breathes more easily because upward pressure on her diaphragm is reduced. However, increased pressure on her bladder causes her to urinate more frequently. Pressure of the fetal head in the pelvis also may cause leg cramps and edema. Lightening (descent of the fetus toward the pelvic inlet before labor) is most noticeable in primiparas and occurs about 2 to 3 weeks before the natural onset of labor. Instructions for labor, although correct, do not address the patient's statement of being able to breathe easier. Fetal movement continues throughout the final weeks of gestation. A decrease in fetal movement is a concerning sign and the health care provider must be notified.
