Final answer:
Moderate variability of the fetal heart rate (FHR) is considered normal.
Step-by-step explanation:
The nurse would identify moderate variability of the fetal heart rate (FHR) as normal. Variability refers to the fluctuations in the FHR, and it is an important indicator of fetal well-being. A normal FHR should have moderate variability, which means that there are fluctuations in the heart rate of the fetus. Absent variability, minimal variability, or marked variability are abnormal and may indicate fetal distress or other issues.
