Final answer:
The Biophysical Profile (BPP) can estimate fetal weight and evaluate fetal lie, presentation, and position. Amniocentesis and Chorionic Villus Sampling (CVS) are used to diagnose genetic disorders, not estimate fetal weight or evaluate fetal position. The Non-Stress Test (NST) measures the baby's heart rate in response to movement and assesses overall health.
Step-by-step explanation:
A) The Biophysical Profile (BPP) is a prenatal test that uses ultrasound and sometimes, fetal heart rate monitoring to evaluate the wellbeing of a fetus. It helps estimate fetal weight and assess fetal lie (position and altitude), presentation (the part of the fetus that is coming down into the birth canal), and position (the relationship between the baby's head and the mother's pelvis).
B) Amniocentesis is a prenatal test that involves taking a sample of the amniotic fluid surrounding the fetus. It is used to diagnose genetic disorders and certain birth defects, not to estimate fetal weight or evaluate fetal position.
C) Chorionic Villus Sampling (CVS) is another prenatal test that involves taking a sample of cells from the placenta. It is also used to diagnose genetic disorders and certain birth defects, not to estimate fetal weight or evaluate fetal position.
D) The Non-Stress Test (NST) is a prenatal test that measures the baby's heart rate in response to movement. It is used to assess the baby's overall health and well-being, not to estimate fetal weight or evaluate fetal position.
