CEFM NEWEST EXAM QUESTIONS AND DETAILED
CORRECT ANSWERS (VERIFIED ANSWERS) | A+
GRADE
What is the primary goal of fetal monitoring? - ans -To prevent fetal and maternal
morbidity and mortality (prevent injury and death to mother and baby)
Baby's oxygen in uterus is ___% - ans -30%
The umbilical vein carries well oxygenated blood from? - ans -Placenta to fetus
The umbilical artery carries what from where? - ans -Carries waste products away
from the fetus to the placenta
Having a baby with a two vessel cord increases the risk of what? - ans -Resp.
Acidosis
Hematocrit should be __x Hgb - ans -3x
Fetal blood has a higher ____ concentration than adult blood, allowing for greater
oxygen carrying capacity - ans -Hemoglobin
Fetal hgb has a higher affinity for - ans -Oxygen
Moms Hgb affinity is less than or greater than baby's? - ans -Less than
When mom has a fever why does this cause not as much oxygen for baby? - ans -
When mom has a fever oxygen releases more freely thus baby doesn't get as
much
Do you want symmetric or asymmetric IUGR and why? - ans -Asymmetric cause
you want bigger head/chest and little arms/legs so you know oxygen went to the
vital organs
, What are some extrinsic factors that influence fetal oxygenation? - ans --maternal
influences (asthma, high BP, diabetes, pushing, anxiety, etc.
-umbilical cord
-amniotic fluid characteristics
-uterus
-placenta
What is normal amniotic fluid? - ans -6-25
Why could amniotic fluid extrinsiclg affect fetal oxygenation? - ans -Oligo - cord
compression
Poly - cord prolapse, knots/nuchal
____-_____mL of blood profuse the uterus each minute - ans -700-800mL
Uterine blood flow is dependent on maternal? - ans -Blood pressure
How does the baby exchange gases and get rid of waste in utero? - ans -Passive
diffusion that occurs in the chorionic villa in placenta
What happens to this passive diffusion with a contraction? - ans -Contraction
clamps down the vessels and causes diminished or stops diffusion
CTX of at least 30mmHg causes ____ blood flow - ans -Diminshed
CTX of what completely stops blood flow of placenta intravillous space and baby
has to rely on reserves? - ans -50mmHg and above
Placenta breaks or leaks can cause? - ans -Amniotic fluid embolism
What decelerations signal interruption of oxygen transfer with extrinsic factors
(mom lungs, mom heart, mom vasculature, uterus, placenta, cord)? - ans -
Variable late or prolonged decelerations
Moderate variability or acceleration reliably predict? - ans -The abscence of
metabolic acidemia
