transducer and the fetal spiral electrode. Correct Answers: True

warm water to make cleaning easier. Correct Answers: False

variability. Correct Answers: True

and labeled a test. 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: 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: The heart rate from a well-applied fetal spiral electrode can only be fetal, not maternal. Correct
Answers: False

T/F: The internal spiral electrode may pick up the maternal heart rate if the baby has died. Correct
Answers: True
T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings. Correct Answers:
True
T/F: Variability and periodic changes can be detected with both internal and external monitoring.
Correct Answers: True
T/F: Variable decelerations are a result of cord compression. Correct Answers: True
T/F: The presence of FHR accelerations in the intrapartum and antepartum periods is a sign of
adequate fetal oxygenation. Correct Answers: True
,T/F: Variable decelerations are a vagal response. Correct Answers: True
T/F: Late decelerations have a gradual decrease in FHR (onset to nadir 30 seconds) and are delayed
in timing with the nadir of the deceleration occurring after the peak of the contraction. Correct
Answers: True
T/F: The fetal heart rate baseline can be determined during periods of marked variability. Correct
Answers: False
T/F: Anything that affects maternal blood flow (cardiac output) can affect the blood flow through the
placenta. Correct Answers: True
T/F: Variable decelerations are the most frequently seen fetal heart rate deceleration pattern in labor.
Correct Answers: True
T/F: Minimal variability is always an indicator of hypoxia and a Cesarean section is indicated. Correct
Answers: False
