ANSWERS GRADED A+
nervous system that decreases FHR - ANSWER✔✔✨---parasympathetic
nervous system that increases FHR - ANSWER✔✔✨---sympathetic
fetal baroreceptors - ANSWER✔✔✨---send signals to midbrain for vagal stimulation causing abrupt
FHR variable decels
fetal chemoreceptors - ANSWER✔✔✨---slows FHR causing late decels, variable r/t cord compression
with hypoxemia, and prolonged r/t hypoxemia
fetal norepinephrine and epinephrine - ANSWER✔✔✨---in response to stress FHR increases and
shunts blood to vital organs (brain, heart, adrenal glands)
fetal reninangiotensin system - ANSWER✔✔✨---regulates normal fetal circulation, umbilical
placental blood flow
fetal prostaglandins - ANSWER✔✔✨---maintains patency of fetal ductus artriosus, regulation of
umbilical blood flow
fetal quiet sleep - ANSWER✔✔✨---normal baseline, minimal variability, accelerations absent. non-
reactive NST but responds to external stimuli
fetal active rem sleep - ANSWER✔✔✨---normal baseline, moderate variability, accelerations
present.
