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 - CORRECT ANSWERS e. 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 NCC Electronic Fetal Monitoring Certification Exam 2022(100% Verified) T/F: The monitor should always be tested before starting a tracing, either external or internal mode and labeled a test. - CORRECT ANSWERS True T/F: The spiral electrode is used to more accurately determine the frequency, duration, and intensity of uterine contractions. - CORRECT ANSWERS False 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. - CORRECT ANSWERS True T/F: The external toco gives measurable uterine pressure. - CORRECT ANSWERS False T/F: The fetal spiral electrode can be placed when vaginal bleeding of unknown origin is present. - CORRECT ANSWERS False 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. - CORRECT ANSWERS
