5. The vagus nerve begins maturation 26 to 28 weeks. Its b. Decreases baseline
dominance results in what effect to the FHR baseline?
a. Increases baseline
b. Decreases baseline
6. T/F: Oxygen exchange in the placenta takes place in True
the intervillous space.
7. T/F: The parasympathetic nervous system is a car- False
dioaccelerator.
8. T/F: Baroreceptors are stretch receptors which re- True
spond to increases or decreases in blood pressure.
9. T/F: There are two electronic fetal monitoring meth- True
ods of obtaining the fetal heart rate: the ultrasound
transducer and the fetal spiral electrode.
10. T/F: Variability can be determined with the fetoscope. False
11. T/F: Because the ultrasound transducer and toco False
transducer are sealed units, they can be dipped in
warm water to make cleaning easier.
12. T/F: The most common artifact with the ultrasound True
transducer system for fetal heart rate is increased
variability.
13. T/F: All fetal monitors contain a logic system designed True
to reject artifact.
14. T/F: The monitor should always be tested before start- True
ing a tracing, either external or internal mode and
labeled a test.

15. T/F: The paper speed on the fetal monitor should al- False
ways be set at 1cm/min.
16. T/F: Both internal and external monitoring methods False
are equally accurate means of obtaining the fetal
heart rate and contraction patterns.
17. T/F: The external toco is usually placed over the uter- True
ine fundus to pick up contractions.
18. T/F: The external toco gives measurable uterine pres- False
sure.
19. T/F: The fetal spiral electrode can be placed when False
vaginal bleeding of unknown origin is present.
20. T/F: The ultrasound transducer is usually placed on True
the side of the uterus over the baby's back, as the fetal
heart is heard best there.
21. T/F: The spiral electrode is used to more accurately False
determine the frequency, duration, and intensity of
uterine contractions.
22. T/F: The heart rate from a well-applied fetal spiral False
electrode can only be fetal, not maternal.
23. T/F: The intrauterine catheter is used to pick up the False
fetal heart rate.
24. T/F: The internal spiral electrode may pick up the ma- True
ternal heart rate if the baby has died.

25. T/F: Fetal arrhythmias can be seen on both internal True
and external monitor tracings.
26. T/F: Variability and periodic changes can be detected True
with both internal and external monitoring.
27. T/F: Variable decelerations are a result of cord com- True
pression.
28. T/F: The presence of FHR accelerations in the intra- True
partum and antepartum periods is a sign of adequate
fetal oxygenation.
29. T/F: Variable decelerations are a vagal response. True
30. T/F: Late decelerations have a gradual decrease in FHR True
(onset to nadir 30 seconds) and are delayed in timing
with the nadir of the deceleration occurring after the
peak of the contraction.
31. T/F: The fetal heart rate baseline can be determined False
during periods of marked variability.
32. T/F: Anything that affects maternal blood flow (cardiac True
output) can affect the blood flow through the placen-
ta.
33. T/F: Variable decelerations are the most frequently True
seen fetal heart rate deceleration pattern in labor.
34. T/F: Minimal variability is always an indicator of hypox- False
ia and a Cesarean section is indicated.
