NCC Electronic Fetal Monitoring Certification Exam Questions and
Answers (2024) (Verified Answers)
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 -answer-b. Decreases baseline
T/F: Oxygen exchange in the placenta takes place in the intervillous space. -
answer-True
T/F: The parasympathetic nervous system is a cardioaccelerator. -answer-False
T/F: Baroreceptors are stretch receptors which respond to increases or
decreases in blood pressure. -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. -answer-True
T/F: Variability can be determined with the fetoscope. -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. -answer-False
T/F: The most common artifact with the ultrasound transducer system for fetal
heart rate is increased variability. -answer-True
T/F: All fetal monitors contain a logic system designed to reject artifact. -answer-
True
T/F: The monitor should always be tested before starting a tracing, either external
or internal mode and labeled a test. -answer-True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min. -
answer-False
T/F: Both internal and external monitoring methods are equally accurate means of
obtaining the fetal heart rate and contraction patterns. -answer-False
T/F: The external toco is usually placed over the uterine fundus to pick up
contractions. -answer-True
T/F: The external toco gives measurable uterine pressure. -answer-False
,T/F: The fetal spiral electrode can be placed when vaginal bleeding of unknown
origin is present. -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. -answer-True
T/F: The spiral electrode is used to more accurately determine the frequency,
duration, and intensity of uterine contractions. -answer-False
T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal, not
maternal. -answer-False
T/F: The intrauterine catheter is used to pick up the fetal heart rate. -answer-
False
T/F: The internal spiral electrode may pick up the maternal heart rate if the baby
has died. -answer-True
T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings.
-answer-True
T/F: Variability and periodic changes can be detected with both internal and
external monitoring. -answer-True
, T/F: Variable decelerations are a result of cord compression. -answer-True
T/F: The presence of FHR accelerations in the intrapartum and antepartum
periods is a sign of adequate fetal oxygenation. -answer-True
T/F: Variable decelerations are a vagal response. -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. -answer-True
T/F: The fetal heart rate baseline can be determined during periods of marked
variability. -answer-False
T/F: Anything that affects maternal blood flow (cardiac output) can affect the
blood flow through the placenta. -answer-True
T/F: Variable decelerations are the most frequently seen fetal heart rate
deceleration pattern in labor. -answer-True
T/F: Minimal variability is always an indicator of hypoxia and a Cesarean section is
indicated. -answer-False
