When should a woman undergo a Non-Stress Test (NST)?

• A. Before 20 weeks of pregnancy
• B. At 27 weeks or more
• C. During the second trimester
• D. Only during labor

Answer: (B)

A Non-Stress Test (NST) is a crucial assessment used to monitor fetal well-being by measuring the fetal heart rate in response to movements. The ideal time for a woman to undergo an NST is at 27 weeks or more gestation. This is because, by this point in the pregnancy, the fetus has developed sufficiently, and the healthcare provider can better assess the health of the fetus through the test. Conducting an NST before 27 weeks is not common practice as the fetus is still developing key physiological capabilities that affect heart rate patterns. Additionally, during the second trimester, typically defined as weeks 13 to 26, the fetus may not have matured enough for the NST to yield reliable results. Using the NST only during labor can also be limiting, as this test is designed for monitoring the fetus throughout the third trimester and can help identify potential issues requiring intervention before labor begins. Hence, the 27-week mark is a significant point in fetal development for the NST to be effectively utilized.
