What does a negative contraction stress test indicate?

• A. Normal fetal response with no late decelerations
• B. Need for immediate delivery
• C. Fetal distress
• D. Possible complication with the placenta

Answer: (A)

A negative contraction stress test indicates a normal fetal response, which is characterized by the absence of late decelerations in the fetal heart rate during contractions. This outcome suggests that the fetus is not experiencing distress and can tolerate the stress of labor well.

Late decelerations are often associated with uteroplacental insufficiency, meaning that the placenta is not delivering enough blood to the fetus. When a contraction stress test yields a negative result, it implies that the fetus is getting adequate oxygen and blood flow, and hence, there is no evidence of late decelerations that typically signify a problem.

In contrast, the other options suggest various complications or needs that do not align with the meaning of a negative result from a contraction stress test. Immediate delivery would generally be indicated by signs of fetal distress or complications, while a positive test result would suggest further investigation as it may highlight issues with the placenta or fetal wellbeing.
