In a cephalic presentation, where is the fetal heart rate best heard?

• A. Lower quadrant of the abdomen
• B. Upper quadrant of the abdomen
• C. At the umbilicus
• D. At the apex of the heart

Answer: (A)

In cephalic presentation the head is down toward the birth canal, so the fetal chest sits closer to the lower part of the maternal abdomen. That makes the fetal heartbeat easiest to hear through the abdominal wall in the lower quadrant, typically just below the umbilicus. Listening higher up, at the upper abdomen or near the umbilicus, is less reliable because the fetal chest isn’t as close to the abdominal wall there. The heartbeat isn’t heard best at the apex of the mother’s heart since that location is in the chest, not over the fetal chest.
