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 Less]
