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

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 monitor should always be tested before starting a tracing, either external or internal
mode 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 intrauterine catheter is used to pick up the fetal heart rate. 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

What is your first intervention in management of a patient experiencing variable decelerations?
a. Immediate delivery
b. Change maternal position
c. No treatment indicated

Etiology of a baseline FHR of 165bpm occurring for the last hour can be:
1. Maternal supine hypotension
2. Maternal fever
3. Maternal dehydration
4. Unknown
a. 1 and 2
b. 1, 2 and 3
c. 2, 3 and 4 correct answers c. 2, 3 and 4

What is the most probable cause of recurrent late decelerations?
a. Utero-placental insufficiency

c. 4 fetal heart rate accelerations in a 40 minute window
d. 2 fetal heart rate accelerations in a 20 minute window correct answers d. 2 fetal heart rate
