Inpatient Obstetric Nurse (NCC) Practice Exam

What does it indicate if variable decelerations during the NST are nonrepetitive and last less than 30 seconds?

1. The fetus is considered compromised

2. There is little to no need for intervention

3. Immediate delivery is required

4. Further monitoring is essential

The correct answer is: There is little to no need for intervention

Variable decelerations during a non-stress test (NST) can be indicative of umbilical cord compression, which can occur intermittently during labor. Nonrepetitive variable decelerations that last less than 30 seconds generally suggest that the fetus is managing well and is not experiencing significant distress. If these decelerations are not recurring and are short-lived, it typically indicates a transient situation rather than a concerning one. In this context, classifying the fetus as being in a well-tolerated state means that there is minimal risk present, and thus, there is little to no need for immediate intervention. Continuous observation may still be warranted to ensure that the condition does not change, but immediate actions or interventions are not required if the decelerations remain infrequent and brief. This understanding is essential in order to effectively monitor the fetus and decide upon further actions during labor.
