AWHONN Advanced Fetal Monitoring
Exam Rated A+
10 to 15 minutes - ANSWER-What is the biologic half-life of oxytocin?
10x10 - ANSWER-What accelerations do gestations less than 32 weeks need?
2 to 4 mu - ANSWER-At what rate is exogenous oxytocin at for the mother during the
first stage of labor?
22 to 24 greater than 22 - ANSWER-What is the normal HCO3 in an umbilical artery?
3 mu - ANSWER-At what rate is exogenous oxytocin at for the fetus during the first
stage of labor?
30 to 60 minutes - ANSWER-How long does it take to reach a steady state of plasma
concentration for Pitocin?
49 to 56
Less than 60 - ANSWER-What is the normal PCO2 for an umbilical artery?
5-25 - ANSWER-What is a normal AFI?
50 to 70 bpm - ANSWER-What ventricular rate in a fetus is associated with a complete
or third-degree heart block?
51-56% - ANSWER-What is the fetal Hct?
60-90 minutes - ANSWER-How one does it take for significant acidemia to take place?
60% - ANSWER-What percentage is uteroplacental blood flow decreased by during
cxts?
7.20-7.29
Greater than or equal to 7.10 - ANSWER-What is normal pH in the umbilical artery?
8 to 10 - ANSWER-What is the normal value for a BPP?
80-100 mL/kg - ANSWER-What is a normal blood volume for a fetus at term?
A pacemaker implantation - ANSWER-How can a complete heart block be treated in a
neonate?
, Accelerations peak greater than 15 bpm above the baseline and last for greater than 15
seconds - ANSWER-What is a reactive NST for greater than 32 weeks?
Accelerations with a peak of greater than 10 bpm above the baseline and duration of
longer than 10 seconds - ANSWER-What is a reactive NST for less than 32 weeks?
Acetylcholine is released which decreases the intrinsic heart rate
Vagus stimulation - ANSWER-What happens when the parasympathetic nervous
system is stimulated?
Adrenergic activity - ANSWER-What is marked variability mediated by?
Aerobic metabolism with O2 then there's hypoxemia (decrease in O2) which leads to
tissue hypoxia. The body is forced to resort to anaerobic metabolism which leads to a
buildup of lactic acid in the blood. This then causes metabolic acidosis (causes cellular
death). - ANSWER-Explain the oxygenation depletion cascade
An NST, fetal breathing movement, fetal movement, fetal tone, and amniotic fluid
volume - ANSWER-What does a biophysical profile or BPP consist of?
anaerobic metabolism - ANSWER-The metabolism that takes place in the absence of
oxygen; the principle product is lactic acid.
Any type of bleeding - ANSWER-What is a contraindication for terbutaline?
Assess his vascular resistance to blood flow within the placenta
Monitors for IUGR - ANSWER-What does a umbilical artery Doppler velocimetry do?
At least three contractions and a 10 minute span each lasting greater than 40 seconds -
ANSWER-How many contractions are needed for a contraction stress test?
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?
Bradycardia and hypertension - ANSWER-What effect do chemoreceptors have?
By sending and receiving US waves through the mothers abdomen
When the waves are reflected from moving objects like the fetal heart the frequency
changes slightly
This change is then analyzed by the electronics inside the transducer and converted
into audible beeps - ANSWER-How do you fetal dopplers work?
Can decrease variability and accelerations - ANSWER-What do narcotics to you in
regards to fetal heart rates?
