All of the above How does the fetus compensate for decreased maternal circulating volume? 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. - CORRECT ANSWERS b. Increases cardiac output by increasing it's heart rate. 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 - CORRECT ANSWERS a. A decrease in the heart rate 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 - CORRECT ANSWERS g. C & D 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 - CORRECT ANSWERS b. Decreases baseline 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
