Final answer:
The method for evaluating fetal status during the antepartum period by observing the response of the fetal heart rate to fetal movement is known as a Nonstress test, where 'Reactive' indicates a normal response and 'Non-reactive' may require further evaluation.
Step-by-step explanation:
The method for evaluating fetal status during the antepartum period by observing the response of the fetal heart rate to fetal movement and differentiating between Reactive vs Non-reactive is referred to as a) Nonstress test.
A nonstress test is a common prenatal test used to check on a baby's health. During a nonstress test, a baby's heart rate is monitored to see how it responds to the baby's movements. The term "reactive" refers to a normal test result, indicating that the baby's heart rate increases normally as the baby moves. "Non-reactive" suggests that the baby's heart rate is not increasing as expected, which might require further testing to ensure the baby's well-being.
This test is distinct from other tests such as the contraction stress test, biophysical profile, and vibroacoustic stimulation, which are used in different circumstances or combine other fetal health indicators.
