The tracing shown is from a woman at 28-weeks gestation in the post-anesthesia care unit...

Comprehensive and Detailed Explanation From Exact Extract–Based NCC C-EFM References:

The fetal heart rate tracing shows:

Baseline around 140 bpm

Minimal variability

No accelerations

No decelerations

Regular uterine activity but not tachysystole

This pattern is Category II, but in the context of:

28-week gestation

Immediate postoperative status after anesthesia

Maternal alertness and stability

NCC and AWHONN emphasize that maternal sedation, post-anesthesia effects, medications, and physiologic stress commonly cause temporary minimal variability without acidemia, especially at preterm gestations where baseline variability is normally lower.

Key NCC principle:

Minimal variability in a stable mother without decelerations does NOT require emergent delivery.

Instead, the fetus should be observed as anesthesia effects wear off.

Why other answers are incorrect:

A. Terbutaline – No tachysystole and no recurrent decels are present.

C. Cesarean birth – No bradycardia, no late decels, no absent variability, and no Category III criteria.

Thus, appropriate management is B. Continued monitoring.
