During a labor assessment, a client at 42 weeks gestation shows fetal tachycardia (190 bpm) for 10 minutes with extremely active fetus and strong contractions. Which finding would indicate fetal hypoxia?

During a labor assessment, a client at 42 weeks gestation shows fetal tachycardia (190 bpm) for 10 minutes with extremely active fetus and strong contractions. Which finding would indicate fetal hypoxia?

• A. Decreased fetal activity.
• B. Fetal bradycardia.
• C. Excessive fetal activity and fetal tachycardia.
• D. Normal fetal heart rate with variability.

Answer: (C)

Fetal hypoxia often starts with a sympathetic response that raises the heart rate. When the fetus is under stress, you can see tachycardia and sometimes the fetus is unusually active as it responds to the low oxygen. In this scenario, a persistently very high heart rate (tachycardia) combined with excessive fetal activity points to ongoing distress from insufficient oxygenation. As hypoxia progresses, activity may decline and variability can fall, and later still you’d see bradycardia. Normal variability with a normal rate is reassuring, and decreased activity on its own can be a late sign. So the combination of excessive activity and tachycardia is the pattern most consistent with fetal hypoxia in this context.
