Explanation
a. The nonstress test is considered reactive if there are two or more accelerations of the fetal heart rate (FHR) in a 20-minute period, lasting 15 seconds or longer and peaking at least 15 beats per minute above the baseline. The FHR baseline is between 110 and 160 beats per minute, with moderate variability. The test is considered nonreactive if these criteria are not met.
