c. Increases cardiac output by increasing fetal movement.
b. Increases cardiac output by increasing it's heart rate.
Stimulating the vagus nerve typically produces:

c. An increase in stroke volume
d. No change
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
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
b. Decreases baseline
T/F: Oxygen exchange in the placenta takes place in the intervillous space.
True
T/F: The parasympathetic nervous system is a cardioaccelerator.
False
T/F: Baroreceptors are stretch receptors which respond to increases or
decreases in blood pressure.
True
T/F: There are two electronic fetal monitoring methods of obtaining the fetal heart
rate: the ultrasound transducer and the fetal spiral electrode.
True
T/F: Variability can be determined with the fetoscope.
False
T/F: Because the ultrasound transducer and toco transducer are sealed units,
they can be dipped in warm water to make cleaning easier.
False
T/F: The most common artifact with the ultrasound transducer system for fetal
heart rate is increased variability.
True
T/F: All fetal monitors contain a logic system designed to reject artifact.
True
T/F: The monitor should always be tested before starting a tracing, either external
or internal mode and labeled a test.
True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min.
False
T/F: Both internal and external monitoring methods are equally accurate means of
obtaining the fetal heart rate and contraction patterns.
False
