Cefm Exam Questions & Answers
2025/2025
nervous system that decreases FHR - ANSWERSparasympathetic
nervous system that increases FHR - ANSWERSsympathetic
fetal baroreceptors - ANSWERSsend signals to midbrain for vagal stimulation causing abrupt FHR
variable decels
fetal chemoreceptors - ANSWERSslows FHR causing late decels, variable r/t cord compression
with hypoxemia, and prolonged r/t hypoxemia
fetal norepinephrine and epinephrine - ANSWERSin response to stress FHR increases and shunts
blood to vital organs (brain, heart, adrenal glands)
fetal reninangiotensin system - ANSWERSregulates normal fetal circulation, umbilical placental
blood flow
fetal prostaglandins - ANSWERSmaintains patency of fetal ductus artriosus, regulation of
umbilical blood flow
fetal quiet sleep - ANSWERSnormal baseline, minimal variability, accelerations absent. non-
reactive NST but responds to external stimuli
fetal active rem sleep - ANSWERSnormal baseline, moderate variability, accelerations present.
