While caring for a client in labor, which assessment finding best indicates fetal well-being to the nurse?

A. "Presence of late decelerations with each contraction during monitoring." Late decelerations indicate uteroplacental insufficiency, which can lead to fetal hypoxia and distress. This is not a reassuring sign. B. "Increased fetal movement between contractions." While fetal movement is a positive sign, it is not the best indicator of fetal well-being in labor. Continuous FHR monitoring provides a better assessment. C. "Fetal heart rate of 160 beats per minute with moderate variability." A normal fetal heart rate (FHR) is 110–160 bpm, and moderate variability (6–25 bpm fluctuations) indicates a well-oxygenated fetus with an intact autonomic nervous system. D. "Fetal heart rate consistently below 120 beats per minute with no accelerations." A persistent FHR below 110 bpm (bradycardia) or minimal variability suggests possible fetal compromise.
