Document Content and Description Below

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: e. 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.: b. 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: 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: 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: b. Decreases baseline 6. T/F: Oxygen exchange in the placenta takes place in the intervillous space.: True 7. T/F: The parasympathetic nervous system is a cardioaccelerator.: False 8. T/F: Baroreceptors are stretch receptors which respond to increases or decreases in blood pressure.: 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.: True 10. T/F: Variability can be determined with the fetoscope.: 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.: False 12. T/F: The most common artifact with the ultrasound transducer system for fetal heart rate is increased variability.: 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.: True 15. T/F: The paper speed on the fetal monitor should always be set at 1cm/min.: False 16. T/F: Both internal and external monitoring methods are equally accurate means of obtaining the fetal heart rate and contraction patterns.: False 17. 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.: True 18. T/F: The spiral electrode is used to more accurately determine the fre- quency, duration, and intensity of uterine contractions.: False 19. T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal, not maternal.: False 20. T/F: The intrauterine catheter is used to pick up the fetal heart rate.: False 21. T/F: The internal spiral electrode may pick up the maternal heart rate if the baby has died.: True 22. T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings.: True 23. T/F: Variability and periodic changes can be detected with both internal and external monitoring.: True 24. T/F: Variable decelerations are a result of cord compression.: True 25. T/F: The presence of FHR accelerations in the intrapartum and antepar- tum periods is a sign of adequate fetal oxygenation.: True 26. T/F: Variable decelerations [Show More]
