What is the normal fetal heart rate range for a healthy fetus around term?

• A. 60-100
• B. 110-160
• C. 170-190
• D. 80-100

Answer: (B)

Normal fetal heart rate around term is 110 to 160 beats per minute. This range reflects mature autonomic control and adequate oxygenation of the fetus. Rates below 110 (bradycardia) can signal problems such as fetal hypoxia, umbilical cord issues, or effects of medications, and warrant assessment if persistent. Rates above 160 (tachycardia) may be seen with fetal distress, maternal fever, infection, or fetal arrhythmias, and also require evaluation if sustained. Brief fluctuations happen with fetal movement and sleep cycles, but the key point is that a persistent resting rate in the 110–160 range is considered normal at term.
