NCC Electronic Fetal Monitoring Certification Exam (Verified Answers)

• Which of the following factors can have a negative effect on uterine blood

flow?

• Hypertension
• Epidural
• Hemorrhage
• Diabetes
• All of the above

ANS All of the above

• How does the fetus compensate for decreased maternal circulating vol-

ume?

• Increases cardiac output by increasing stroke volume.
• Increases cardiac output by increasing it's heart rate.
• 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 decrease in the heart rate
• An increase in the heart rate
• An increase in stroke volume
• No change

ANS A decrease in the heart rate

• What initially causes a chemoreceptor response?
• Epidurals
• Supine maternal position
• Increased CO2 levels
• Decreased O2 levels
• A & C
• A & B

g. C & D: ANS g. C & D

• The vagus nerve begins maturation 26 to 28 weeks. Its dominance results

in what effect to the FHR baseline?

• Increases baseline
• Decreases baseline

ANS Decreases baseline

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

space ANS True 2 / 4

3 / 63

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 3 / 4

4 / 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

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

• 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
