5. 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)Decreases baseline

6.T/F: Oxygen exchange in the placenta takes place in the

intervillous space (Answer) True

7.T/F: The parasympathetic nervous system is a cardioaccelerator (Answer)False

8.T/F: Baroreceptors are stretch receptors which respond to increases

or decreases in blood pressure (Answer) True

3 / 63

9.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

10.T/F: Variability can be determined with the fetoscope (Answer) False

11.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

12.T/F: The most common artifact with the ultrasound transducer system

for fetal heart rate is increased variability (Answer) True

13. T/F: All fetal monitors contain a logic system designed to reject artifact.: True

14.T/F: The monitor should always be tested before starting a tracing,

either external or internal mode and labeled a test (Answer) True

15.T/F: The paper speed on the fetal monitor should always be set

at 1cm/min (Answer) False

16.T/F: Both internal and external monitoring methods are equally

accurate means of obtaining the fetal heart rate and contraction patterns

(Answer) False

17.T/F: The external toco is usually placed over the uterine fundus to pick

up contractions (Answer) True

18.T/F: The external toco gives measurable uterine pressure (Answer) False19.T/F: The fetal spiral electrode can be placed when vaginal bleeding

of unknown origin is present (Answer) False

4 / 63

20.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

21.T/F: The spiral electrode is used to more accurately determine the

fre- quency, duration, and intensity of uterine contractions (Answer)

False

22.T/F: The heart rate from a well-applied fetal spiral electrode can only

be fetal, not maternal (Answer) False

23.T/F: The intrauterine catheter is used to pick up the fetal heart rate

(Answer) False

24.T/F: The internal spiral electrode may pick up the maternal heart rate if

the baby has died (Answer) True

25.T/F: Fetal arrhythmias can be seen on both internal and external

monitor tracings (Answer) True

26.T/F: Variability and periodic changes can be detected with both

internal and external monitoring (Answer) True
