How is a nonreactive result determined in a nonstress test for a pregnant client?

A nonreactive result in a nonstress test is identified by the absence of accelerations in the fetal heart rate following fetal movements. In this context, fetal accelerations are critical indicators of fetal well-being; they suggest that the fetus is receiving adequate oxygen and is experiencing normal neurological function.

For a nonstress test to be considered reactive, there must typically be at least two accelerations of the fetal heart rate that respond to movements within a specified time frame. Consequently, if no such accelerations occur despite the presence of fetal movements, it indicates a nonreactive status, raising concerns about potential fetal distress or other issues that may need further assessment or monitoring.

Understanding this helps practitioners determine the appropriate next steps in fetal monitoring and care, as the absence of accelerations can lead to additional testing to ensure the health of both the fetus and the mother.
