MONITORING ACTUAL TEST QUESTIONS
WITH COMPLETE ANSWER KEY
●● Severe astha, cardiac issues, and ecclampic seizures
Answer: What maternal conditions greatly impact fetal oxygenation?
●● intervillous space
Answer: Where does the exchange of O2 and nutrients take place?
●● O2 enters the intervillous space via the maternal arteries, to the villi
then the umbilical vein take the o2 blood to the fetus. The umbilical
arteries take the deO2 blood from the baby through the villi and back to
the mother
Answer: How is o2 blood transferred to the fetus?
●● High to low concentration
Mom to fetus for O2
Low to high concentration for CO2 so baby to mom
Answer: Diffusion
●● Diffusion
,Answer: How is O2 transferred from mom to baby
●● Carry O2 into intervillous space
Are maximally dilated so they can not be increased
Answer: Explain spiral arteries in placenta
●● Maternal conditions like pre-e and cardiac disease
Maternal hypotension
Placental changes- abruptions, infections, edema, or smaller size
Excessive uterine activity
Vasoconstriction
Answer: What are factors that can decrease uteroplacental blood flow?
●● They are constricted which decreases blood flow
Answer: What happens to the spiral arteries during pre-e?
●● The aorta and vena cava get compressed (20 weeks)
Answer: Why does the supine position cause decreased uteroplactenal
blood flow?
●● Blocks the sympathetic pathway
Pooling of blood in the lower extremities decreases blood flow back to
moms heart which decreases blood flow to the fetus
, Answer: Why does maternal hypotension happen after regional
analgesia?
●● 60%
Answer: What percentage is uteroplacental blood flow decreased by
during cxts?
●● Environment to lungs to heart to vasculature to uterus to placenta to
umbilical cord
Answer: Explain the pathway for maternal- fetal exchange for fetal
oxygenation (basic)
●● Limbs, kidneys, and descending aorta
Answer: Where is the least O2 blood in the fetus?
●● Umbilical vein and ductous venous
Answer: Where is the most O2 blood in the fetus?
●● Ductus venosus
Answer: Connects the umbilical vein to the inferior vena cava,
bypassing the liver
Shunt that allows most O2 blood to fetal heart
