Final answer:
The Non-stress test (NST) evaluates the fetus's ability to tolerate changes in blood flow/fetal heart rate and oxygenation during contraction. It is a common method used to assess the well-being of the fetus during pregnancy.
Step-by-step explanation:
The test that evaluates the fetus's ability to tolerate changes in blood flow/fetal heart rate and oxygenation during contraction is the Non-stress test (NST). This test is a common method used to assess the well-being of the fetus during pregnancy. It involves monitoring the fetal heart rate and uterine contractions to determine if the fetus is receiving enough oxygen and if the heart rate is responding appropriately to the contractions.
