The vagus nerve begins maturation 26 to 28 weeks. Its dominance results in
what effect to the FHR baseline?
pg. 1
,a. Increases baseline
b. Decreases baseline correct answers b. Decreases baseline
T/F: Oxygen exchange in the placenta takes place in the intervillous space.
correct answers True
T/F: The parasympathetic nervous system is a cardioaccelerator. correct
answers False
T/F: Baroreceptors are stretch receptors which respond to increases or
decreases in blood pressure. correct answers 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
answers True
T/F: Variability can be determined with the fetoscope. correct answers 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 answers
False
T/F: The most common artifact with the ultrasound transducer system for
fetal heart rate is increased variability. correct answers True
T/F: All fetal monitors contain a logic system designed to reject artifact.
correct answers True
T/F: The monitor should always be tested before starting a tracing, either
external or internal mode and labeled a test. correct answers True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min.
correct answers False
pg. 2
,T/F: Both internal and external monitoring methods are equally accurate
means of obtaining the fetal heart rate and contraction patterns. correct
answers False
T/F: The external toco is usually placed over the uterine fundus to pick up
contractions. correct answers True
T/F: The fetal spiral electrode can be placed when vaginal bleeding of
unknown origin is present. correct answers 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 answers
True
T/F: The spiral electrode is used to more accurately determine the frequency,
duration, and intensity of uterine contractions. correct answers False
T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal,
not maternal. correct answers False
T/F: The intrauterine catheter is used to pick up the fetal heart rate. correct
answers False
T/F: The internal spiral electrode may pick up the maternal heart rate if the
baby has died. correct answers True
T/F: Fetal arrhythmias can be seen on both internal and external monitor
tracings. correct answers True
pg. 3
, T/F: Variability and periodic changes can be detected with both internal and
external monitoring. correct answers True
T/F: Variable decelerations are a result of cord compression. correct answers
True
T/F: The presence of FHR accelerations in the intrapartum and antepartum
periods is a sign of adequate fetal oxygenation. correct answers True
T/F: Variable decelerations are a vagal response. correct answers 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 answers True
T/F: The fetal heart rate baseline can be determined during periods of marked
variability. correct answers False
T/F: Anything that affects maternal blood flow (cardiac output) can affect the
blood flow through the placenta. correct answers True
T/F: Variable decelerations are the most frequently seen fetal heart rate
deceleration pattern in labor. correct answers True
T/F: Minimal variability is always an indicator of hypoxia and a Cesarean
section is indicated. correct answers 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
