What test evaluates fetal heart rate (FHR) in response to fetal movement?

• A. Chorionic Villi Sampling
• B. Contraction Stress Test
• C. Amniocentesis
• D. Non-Stress Test

Answer: (D)

The Non-Stress Test is designed to monitor the fetal heart rate in relation to fetal movements, providing important insights into the well-being of the fetus. During this test, a fetal heart monitor is placed on the mother's abdomen to record the heart rate. As the fetus moves, there is typically an increase in the heart rate, which is a reassuring sign that the baby is receiving adequate amounts of oxygen and is in good health.

This test is particularly useful in identifying potential issues with the fetus, as it allows healthcare providers to assess how the fetal heart rate responds to physical movement, thereby gauging the fetus's condition in real-time. It is a non-invasive procedure, making it a preferred choice for monitoring fetal health during pregnancy, especially in high-risk scenarios or when there are concerns about the fetus's well-being.

In contrast, the other options listed serve different purposes, such as sampling placental tissue, assessing uterine contractions, or analyzing amniotic fluid, none of which specifically evaluate fetal heart rate responses to movement.
