T/F: Oxygen exchange in the placenta takes place in the intervillous space. -
CORRECT ANSWER True
T/F: The parasympathetic nervous system is a cardioaccelerator. - CORRECT
ANSWER False
T/F: Baroreceptors are stretch receptors which respond to increases or decreases in
blood pressure. - CORRECT ANSWER 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 ANSWER True
T/F: Variability can be determined with the fetoscope. - CORRECT ANSWER 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 ANSWER False
T/F: The most common artifact with the ultrasound transducer system for fetal heart rate
is increased variability. - CORRECT ANSWER True
T/F: All fetal monitors contain a logic system designed to reject artifact. - CORRECT
ANSWER True
T/F: The monitor should always be tested before starting a tracing, either external or
internal mode and labeled a test. - CORRECT ANSWER True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min. -
CORRECT ANSWER False
T/F: Both internal and external monitoring methods are equally accurate means of
obtaining the fetal heart rate and contraction patterns. - CORRECT ANSWER False
T/F: The external toco is usually placed over the uterine fundus to pick up contractions.
- CORRECT ANSWER True
T/F: The external toco gives measurable uterine pressure. - CORRECT ANSWER False
T/F: The fetal spiral electrode can be placed when vaginal bleeding of unknown origin is
present. - CORRECT ANSWER 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 ANSWER True
T/F: The spiral electrode is used to more accurately determine the frequency, duration,
and intensity of uterine contractions. - CORRECT ANSWER False
T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal, not
maternal. - CORRECT ANSWER False
T/F: The intrauterine catheter is used to pick up the fetal heart rate. - CORRECT
ANSWER False

monitoring. - CORRECT ANSWER True
T/F: Variable decelerations are a result of cord compression. - CORRECT ANSWER
True
T/F: The presence of FHR accelerations in the intrapartum and antepartum periods is a
sign of adequate fetal oxygenation. - CORRECT ANSWER True
T/F: Variable decelerations are a vagal response. - CORRECT ANSWER 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 ANSWER True
T/F: The fetal heart rate baseline can be determined during periods of marked
variability. - CORRECT ANSWER False
T/F: Anything that affects maternal blood flow (cardiac output) can affect the blood flow
through the placenta. - CORRECT ANSWER True
T/F: Variable decelerations are the most frequently seen fetal heart rate deceleration
pattern in labor. - CORRECT ANSWER True
T/F: Minimal variability is always an indicator of hypoxia and a Cesarean section is
indicated. - CORRECT ANSWER False
