T/F: Oxygen exchange in the placenta takes place in the intervillous space. - CORRECT ANSWERS True
T/F: The parasympathetic nervous system is a cardioaccelerator. - CORRECT ANSWERS False
T/F: Baroreceptors are stretch receptors which respond to increases or decreases in blood pressure. - CORRECT ANSWERS True
T/F: There are two electronic fetal monitoring methods of obtaining the fetal heart rate: the ultrasound transducer and the fetal spiral electrode. - CORRECT ANSWERS
True
T/F: Variability can be determined with the fetoscope. - CORRECT ANSWERS False
T/F: Because the ultrasound transducer and toco transducer are sealed units, they can be dipped in warm water to make cleaning easier. - CORRECT ANSWERS
False
T/F: The most common artifact with the ultrasound transducer system for fetal heart rate is increased variability. - CORRECT ANSWERS True
T/F: All fetal monitors contain a logic system designed to reject artifact. - CORRECT ANSWERS True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min. - CORRECT ANSWERS False
T/F: Both internal and external monitoring methods are equally accurate means of obtaining the fetal heart rate and contraction patterns. - CORRECT ANSWERS False
T/F: The external toco is usually placed over the uterine fundus to pick up contractions.
