intervillous space. —ANS: True
T/F: The parasympathetic nervous system is a cardioaccelerator.
—ANS: False
Guru01 - Stuvia
T/F: Baroreceptors are stretch receptors which respond to
increases or decreases in blood pressure. —ANS: True
T/F: There are two electronic fetal monitoring methods of
obtaining the fetal heart rate: the ultrasound transducer and the
fetal spiral electrode. —ANS: True
T/F: Variability can be determined with the fetoscope. —ANS:
False
T/F: Because the ultrasound transducer and toco transducer are
sealed units, they can be dipped in warm water to make cleaning
easier. —ANS: False
T/F: The most common artifact with the ultrasound transducer
system for fetal heart rate is increased variability. —ANS: True
T/F: All fetal monitors contain a logic system designed to reject
artifact. —ANS: True
T/F: The monitor should always be tested before starting a tracing,
either external or internal mode and labeled a test. —ANS: True

3cm/min. —ANS: True

T/F: Both internal and external monitoring methods are equally
accurate means of obtaining the fetal heart rate and contraction
patterns. —ANS: False
T/F: The external toco is usually placed over the uterine fundus to
pick up contractions. —ANS: True
T/F: The external toco gives measurable uterine pressure. —ANS:
False
T/F: The fetal spiral electrode can be placed when vaginal
bleeding of unknown origin is present. —ANS: 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.

—ANS: True
T/F: The spiral electrode is used to more accurately determine the
frequency, duration, and intensity of uterine contractions. —ANS:
Guru01 - Stuvia
False
T/F: The heart rate from a well-applied fetal spiral electrode can
only be fetal, not maternal. —ANS: False
T/F: The intrauterine catheter is used to pick up the fetal heart rate.
—ANS: False
T/F: The internal spiral electrode may pick up the maternal heart
rate if the baby has died. —ANS: True
T/F: Fetal arrhythmias can be seen on both internal and external
monitor tracings. —ANS: True
T/F: Variability and periodic changes can be detected with both
internal and external monitoring. —ANS: True
T/F: Variable decelerations are a result of cord compression. —
ANS: True
T/F: The presence of FHR accelerations in the intrapartum and
antepartum periods is a sign of adequate fetal oxygenation at the
time that it is observed —ANS: True
T/F: Variable decelerations are a vagal response. —ANS: 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. —ANS:
True
T/F: The fetal heart rate baseline can be determined during
periods of marked variability. —ANS: False
T/F: Anything that affects maternal blood flow (cardiac output)
can affect the blood flow through the placenta. —ANS: True
T/F: Variable decelerations are the most frequently seen fetal
heart rate deceleration pattern in labor. —ANS: True
T/F: Minimal variability is always an indicator of hypoxia and a
