What represents a reassuring finding on a nonstress test?

• A. Lack of accelerations during movement.
• B. Accelerations in fetal heart rate with movement indicating adequate oxygenation.
• C. Persistent decelerations with movement.
• D. No fetal movements during the test.

Answer: (B)

During a nonstress test, a reassuring finding is when the fetus’ heart rate accelerates in response to movement, showing adequate oxygenation and a normal autonomic response. These accelerations indicate the fetus is well-oxygenated and able to mount a healthy heart-rate response to activity, signaling fetal well-being. This pattern is what clinicians call a reactive NST. In contrast, lack of accelerations despite movement, or persistent decelerations with movement, can point to fetal hypoxia or uteroplacental insufficiency, and no fetal movements would render the test uninterpretable. So accelerations with movement are the best sign of a reassuring NST.
