During a nonstress test, what indicates that the fetus is responding well to movement?

The acceleration of fetal heart rate during a nonstress test indicates that the fetus is responding well to movement. This response suggests that the fetus is active and healthy, demonstrating a good level of oxygenation and a well-functioning autonomic nervous system.

In a nonstress test, fetal heart rate accelerations are typically evaluated in response to the fetus's own movements or external stimuli. A healthy fetus typically exhibits heart rate accelerations of at least 15 beats per minute above the baseline for at least 15 seconds, which is a reassuring sign.

Other options do not reflect fetal well-being in response to movement. Elevation of maternal heart rate can occur for various reasons unrelated to fetal health. Decreased uterine contractions can indicate a variety of conditions but do not directly correlate with fetal movement response in this context. A maternal report of reduced kicks may indicate reduced fetal activity, which could be a concern rather than a positive sign of fetal response to movement. Thus, the acceleration of fetal heart rate is the most direct and relevant indicator in this scenario.
