470 QUESTIONS AND CORRECT DETAILED ANSWERS
1. Which of the following factors can have a negative effect on uterine blood
flow?
a. Hypertension
b. Epidural
c. Hemorrhage
d. Diabetes
e. All of the above
ANS: e. All of the above
2. How does the fetus compensate for decreased maternal circulating volume?
a. Increases cardiac output by increasing stroke volume.
b. Increases cardiac output by increasing it's heart rate.
c. Increases cardiac output by increasing fetal movement.
,ANS:b. Increases cardiac output by increasing it's heart rate.
3. Stimulating the vagus nerve typically produces:
a. A decrease in the heart rate
b. An increase in the heart rate
c. An increase in stroke volume
d. No change
ANS: a. A decrease in the heart rate
4. 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
ANS: g. C & D
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
ANS: b. Decreases baseline
6. T/F: Oxygen exchange in the placenta takes place in the intervillous space.
ANS: True
, 7. T/F: The parasympathetic nervous system is a cardioaccelerator.
ANS: False
8. T/F: Baroreceptors are stretch receptors which respond to increases or de-
creases in blood pressure.
ANS: True
9. 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
10. T/F: Variability can be determined with the fetoscope.
ANS: 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.
ANS: False
12. T/F: The most common artifact with the ultrasound transducer system for
fetal heart rate is increased variability.
ANS: True
13. T/F: All fetal monitors contain a logic system designed to reject artifact.
ANS: True
