NCC Electronic Fetal Monitoring Certification Exam
(Verified 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 All of the above
2. How does the fetus compensate for decreased maternal circulating vol-
ume?
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 Increases car-diac 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 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 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
decreases 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.-
: True
14. T/F: The monitor should always be tested before starting a tracing, either
external or internal mode and labeled a test ANS True
15. T/F: The paper speed on the fetal monitor should always be set at
1cm/min ANS False
