NCC Electronic Fetal Monitoring Final Exam Questions Graded
A+ 2025
The greater affinity that fetal hemoglobin has for oxygen allows for:
a. easier release of oxygen to the tissues
b. greater binding of oxygen
c. stimulation of erythropoietin release - b. greater binding of oxygen
which statement best describes the relationship between maternal and fetal hemoglobin levels?
a. fetal hemoglobin is higher than maternal hemoglobin
b. maternal hemoglobin is higher than fetal hemoglobin
c. maternal and fetal hemoglobin is the same - a. fetal hemoglobin is higher than maternal hemoglobin
In the healthy fetus, blood flows from the right atrium to the left atrium through the:
a. ductus arteriosis
b. ductus venosus
c. Forman ovale - c. foramen ovale
In the healthy fetus, the umbilical cord enters the fetal abdomen and bypasses the liver through the
a. ductus arteriosis
b. ductus venosus
c. Forman ovale - b. ductus venosus
Stimulation of the sympathetic nervous system causes the fetal heart rate to
a. decrease
b. increase
c. remain the same - b. increase
baroreceptors respond mainly to changes in
,a. blood pressure
b. hormonal changes
c. oxygen and carbon dioxide levels - a. blood pressure
Which statement describes normal uterine activity
a. frequency of 1.5 - 2 minutes
b. intensity of 90mmhg early in labor
c. resting tone less than 20-25 mmHg - c. resting tone less than 20-25mmhg
Greater than 5 contractions in 10 minutes averaged over 30 minutes indicates
A. Excessive uterine activity
B. Hyperstimulation
C. Tachysystole - c. tachysystole
tracing showing early phase of labor. External toco being used and contractions have "spiky appearance"
this is due to:
a. artificat
b. fetal kicks
c. maternal respirations - c. maternal respirations
Tracing showing minimal variability. 10 minutes prior to this was cat 1. The appropriate action at this
time is to:
a. apply oxygen
b. continue to observe
c. perform scalp stimulation - b. continue to observe
"this is considered a sleep cycle - sleep cycles can last 15-25 minutes"
How to calculate mVU - add all the mmHg for contractions during a 10 minute period **subtract the
baseline pressure
, in the above EXTERNAL tracing the intensity of the contraction is:
a. 55mmhg
b. 70mmhg
c. indeterminate - c. indeterminate
Cannot determine strength with external monitors *
A 36 week gestation patient is brought to triage by squad after an MVA on her back. She is not bleeding
and denies pain. She is not short of breath, but c/o dizziness and nausea since they put her on the
gurney. The most likely cause is
A. Abruptio placenta
B. Preterm labor
C. Supine hypotension - c. supine hypotension
One compensatory mechanism that helps maintain oxygen availability to the fetus during maternal
exercise is
A. A decrease in maternal hematocrit
B. Transient increase in uterine blood flow
C. An increase in uterine oxygen uptake - c. an increase in uterine oxygen uptake
Tracing showing prolonged deceleration after recent epidural and intial bolus just delivered. Underlying
cause of this tracing is:
a. maternal vasodilation
b. parasympathetic blockage
c. prolapsed umbilical cord - a. maternal vasodilation
G3 at 39 weeks undergoing eIOL. SVE 6/90/+1. Toco showing tachysystole. Tracing with prolonged
deceleration. Priority action by the nurse would be:
a. apply O2 via NRB
