,T/F: There are two electronic fetal monitoring methods of obtaining the fetal
heart rate: the ultrasound transducer and the fetal spiral electrode. - ✔✔True
T/F: Variability can be determined with the fetoscope. - ✔✔False
T/F: Because the ultrasound transducer and toco transducer are sealed units,
they can be dipped in warm water to make cleaning easier. - ✔✔False
T/F: The most common artifact with the ultrasound transducer system for fetal
heart rate is increased variability. - ✔✔True
T/F: All fetal monitors contain a logic system designed to reject artifact. -
✔✔True
T/F: The monitor should always be tested before starting a tracing, either
external or internal mode and labeled a test. - ✔✔True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min. -
✔✔False
T/F: Both internal and external monitoring methods are equally accurate means
of obtaining the fetal heart rate and contraction patterns. - ✔✔False
T/F: The external toco is usually placed over the uterine fundus to pick up
contractions. - ✔✔True
T/F: The external toco gives measurable uterine pressure. - ✔✔False

, T/F: The fetal spiral electrode can be placed when vaginal bleeding of unknown
origin is present. - ✔✔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. - ✔✔True
T/F: The spiral electrode is used to more accurately determine the frequency,
duration, and intensity of uterine contractions. - ✔✔False
T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal,
not maternal. - ✔✔False
T/F: The intrauterine catheter is used to pick up the fetal heart rate. - ✔✔False
T/F: The internal spiral electrode may pick up the maternal heart rate if the
baby has died. - ✔✔True
T/F: Fetal arrhythmias can be seen on both internal and external monitor
tracings. - ✔✔True
T/F: Variability and periodic changes can be detected with both internal and
external monitoring. - ✔✔True
T/F: Variable decelerations are a result of cord compression. - ✔✔True
T/F: The presence of FHR accelerations in the intrapartum and antepartum
periods is a sign of adequate fetal oxygenation. - ✔✔True
