NCC Electronic Fetal Monitoring
Certification Exam Questions and Answers
(2022/2023) (Verified Answers)

How does the fetus compensate for decreased maternal circulating volume?
a. Increases cardiac output by increasing stroke volume.
b. Increases cardiac output by increasing it's heart rate.
c. Increases cardiac output by increasing fetal movement. -correct answer b.
Increases cardiac output by increasing it's heart rate.

Stimulating the vagus nerve typically produces:
a. A decrease in the heart rate
b. An increase in the heart rate
c. An increase in stroke volume
d. No change -correct answer a. A decrease in the heart rate

c. Increased CO2 levels
d. Decreased O2 levels
e. A & C
f. A & B
g. C & D -correct answer g. C & D

The vagus nerve begins maturation 26 to 28 weeks. Its dominance results in what effect
to the FHR baseline?
a. Increases baseline
b. Decreases baseline -correct answer b. Decreases baseline

T/F: Baroreceptors are stretch receptors which respond to increases or decreases in
blood pressure. -correct answer True

T/F: There are two electronic fetal monitoring methods of obtaining the fetal heart rate:
the ultrasound transducer and the fetal spiral electrode. -correct answer True

T/F: Variability can be determined with the fetoscope. -correct answer False

T/F: Because the ultrasound transducer and toco transducer are sealed units, they can
be dipped in warm water to make cleaning easier. -correct answer False

T/F: The most common artifact with the ultrasound transducer system for fetal heart rate
is increased variability. -correct answer True

T/F: All fetal monitors contain a logic system designed to reject artifact. -correct answer
True

T/F: The monitor should always be tested before starting a tracing, either external or
internal mode and labeled a test. -correct answer True

T/F: The paper speed on the fetal monitor should always be set at 1cm/min. -correct
answer False

T/F: Both internal and external monitoring methods are equally accurate means of
obtaining the fetal heart rate and contraction patterns. -correct answer False

T/F: The external toco is usually placed over the uterine fundus to pick up contractions.
-correct answer True

T/F: The external toco gives measurable uterine pressure. -correct answer False

T/F: The fetal spiral electrode can be placed when vaginal bleeding of unknown origin is
present. -correct answer False

T/F: The ultrasound transducer is usually placed on the side of the uterus over the
baby's back, as the fetal heart is heard best there. -correct answer True

T/F: The spiral electrode is used to more accurately determine the frequency, duration,
and intensity of uterine contractions. -correct answer False

T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal, not
maternal. -correct answer False

T/F: The intrauterine catheter is used to pick up the fetal heart rate. -correct answer
False

T/F: The internal spiral electrode may pick up the maternal heart rate if the baby has
died. -correct answer True

T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings. -
correct answer True

T/F: Variability and periodic changes can be detected with both internal and external
monitoring. -correct answer True

T/F: Variable decelerations are a result of cord compression. -correct answer True

T/F: The presence of FHR accelerations in the intrapartum and antepartum periods is a
sign of adequate fetal oxygenation. -correct answer True

T/F: Variable decelerations are a vagal response. -correct answer True

T/F: Late decelerations have a gradual decrease in FHR (onset to nadir 30 seconds)
and are delayed in timing with the nadir of the deceleration occurring after the peak of
the contraction. -correct answer True

T/F: The fetal heart rate baseline can be determined during periods of marked
variability. -correct answer False

T/F: Anything that affects maternal blood flow (cardiac output) can affect the blood flow
through the placenta. -correct answer True

T/F: Variable decelerations are the most frequently seen fetal heart rate deceleration
pattern in labor. -correct answer True

T/F: Minimal variability is always an indicator of hypoxia and a Cesarean section is
indicated. -correct answer False

What is your first intervention in management of a patient experiencing variable
decelerations?
a. Immediate delivery
b. Change maternal position
c. No treatment indicated
d. Oxygen
e. Stop oxytocin infusion -correct answer b. Change maternal position

Etiology of a baseline FHR of 165bpm occurring for the last hour can be:
1. Maternal supine hypotension
2. Maternal fever
3. Maternal dehydration
4. Unknown
a. 1 and 2
