NCC EFM ACTUAL EXAM EXAM STUDY
SHEET EXAM Q&A 2026 GRADED A+.
⫸ 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. 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 Answer: a. A decrease in the heart rate
⫸ What initially causes a chemoreceptor response?
a. Epidurals
b. Supine maternal position
c. Increased CO2 levels
d. Decreased O2 levels
e. A & C
f. A & B
,g. C & D 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 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
