Questions and Answers

What is the typical range for a healthy fetal heart rate observed on an ultrasound?

  • 160 to 200 beats per minute
  • 150 to 180 beats per minute
  • 100 to 120 beats per minute
  • 120 to 160 beats per minute (correct)
  • Why is the measurement of gestational age during an ultrasound important?

  • To estimate size for delivery
  • To determine the correct position of the mother
  • To ensure proper growth through size measurements of the baby's head, abdomen, and femur (correct)
  • To assess the fetal heart rate variability
  • What role does the placenta play in fetal development?

  • It facilitates the transfer of nutrients and oxygen between mother and baby (correct)
  • It stores all fetal waste products until birth
  • It prevents any substances from crossing to the fetus from the mother
  • It serves as the primary organ for fetal hormone production only

    Study Notes

    Signs of Healthy Development on Ultrasound

    • Fetal Heart Rate typically ranges from 120 to 160 beats per minute; a consistent rhythm indicates normal development.
    • Fetal Movements, such as limb flexion and extension, suggest a healthy nervous system.
    • Measurement of Gestational Age uses the size of the baby's head, abdomen, and femur to estimate age and ensure appropriate growth.
    • Placental Position and Thickness should reflect proper attachment to the uterine wall and adequate thickness for nutrient and oxygen exchange.
    • Amniotic Fluid Levels must be sufficient to indicate healthy kidney function and fetal swallowing processes.
    • Organ Development includes assessing the heart, brain, kidneys, and bladder to confirm proper formation and functionality.
    • Umbilical Cord Blood Flow is evaluated via Doppler ultrasound to ensure adequate oxygen and nutrient supply to the fetus.

    Role of the Placenta

    • Nutrient and Oxygen Transfer occurs through the placenta, linking the mother and baby for essential nutrient delivery and oxygen exchange via the umbilical cord.
    • Waste Removal enables the elimination of waste products, such as carbon dioxide and urea, from the baby's bloodstream back into the mother's circulation.
    • Hormone Production is essential for maintaining pregnancy, with the placenta generating hormones like human chorionic gonadotropin (hCG), progesterone, and estrogen.

    Substances Crossing from Mother to Baby

    • Oxygen is essential for fetal development and crosses the placenta from the mother's bloodstream to the baby.
    • Nutrients, including glucose, amino acids, fatty acids, vitamins, and minerals, are transferred from mother to baby to support growth and development.
    • Antibodies are maternal antibodies that provide passive immunity to the baby during early life stages.
    • Hormones such as insulin and thyroid hormones influence fetal growth and metabolism by crossing the placenta.
