A woman at 39-weeks gestation is in early labor, 2–3 cm dilated, 85% effaced, and...

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

The tracing shows significant artifact, periods of signal loss, and abrupt changes inconsistent with physiologic fetal patterns. This is typical of poor signal quality, not actual fetal decelerations. In early labor at –2 station, external FHR monitoring often loses contact due to fetal position and maternal movement.

NCC and AWHONN emphasize the following when artifact is present:

Correct signal quality before interpreting the tracing.

Troubleshooting steps include:– Adjusting transducer location– Ensuring adequate ultrasound gel– Repositioning the mother– Checking for maternal heart rate contamination

Why the other options are incorrect:

B. IV fluid bolus — Indicated for hypotension or late decelerations, not for artifact.

C. Terbutaline — Used for tachysystole with fetal intolerance; there is no tachysystole shown.

Thus, the correct first step is A. Adjust the fetal monitor.
