What does a reactive nonstress test indicate?

A reactive nonstress test indicates that normal fetal heart rate patterns are observed, which is a sign of a healthy fetus. Specifically, it shows that the fetal heart rate increases appropriately in response to movements, suggesting that the fetus is getting enough oxygen and is not under stress. In a reactive test, there are typically two or more accelerations in the fetal heart rate of at least 15 beats per minute above the baseline, lasting for at least 15 seconds within a 20-minute period. This pattern is reassuring and suggests that the fetus is likely experiencing a normal intrauterine environment.

The other choices do not accurately reflect the implications of a reactive nonstress test. It does not indicate fetal distress, as a non-reactive test would suggest potential issues. Similarly, while the term "negative" may be used in some contexts, a reactive test is generally a positive indicator of fetal well-being. Saying that further testing is required might be appropriate in other circumstances, such as a non-reactive result, but a reactive result suggests that no immediate concern necessitates additional testing.
