Final answer:
In a non-stress test (NST), we want the results to be reactive. This indicates that the fetus is receiving enough oxygen and is in a healthy state. A nonreactive NST may indicate fetal distress or lack of oxygen supply.
Step-by-step explanation:
In a non-stress test (NST), we want the results to be reactive. A reactive NST means that there are at least two accelerations of the fetal heart rate with fetal movement within a certain timeframe. This indicates that the fetus is receiving enough oxygen and is in a healthy state.
On the other hand, if the NST is nonreactive, it means that the fetal heart rate did not show the desired number of accelerations. This could indicate fetal distress or lack of oxygen supply, and further evaluation may be required.
Therefore, a reactive NST is preferable as it suggests a normal and healthy condition for the fetus.
