What was the fetal heart rate in the 28-week bleeding case?

• A. 132/min
• B. 80/min
• C. 100/min
• D. 160/min

Answer: (D)

Fetal heart rate is normally about 110 to 160 beats per minute. In a pregnancy complicated by bleeding, a heart rate that sits at the upper end of that normal range can reflect fetal stress or distress as the fetus responds to the in utero environment. A rate of 160/min is at the high end of normal, and in this scenario it aligns with tachycardia seen when the fetus is under stress from bleeding. The other options fall clearly outside the distress pattern: 132 and 100 are comfortably within the normal range, and 80 is clearly a bradycardia, which would indicate a more concerning or different situation. Thus, the rate described in the case best matches the observed response to bleeding, making 160/min the best choice.
