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 ans - b. Decreases baseline
T/F: Oxygen exchange in the placenta takes place in the intervillous space. Correct ans
- True
T/F: The parasympathetic nervous system is a cardioaccelerator. Correct ans -
False
,T/F: Baroreceptors are stretch receptors which respond to increases or decreases in blood pressure.
Correct ans - 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 ans - True
T/F: Variability can be determined with the fetoscope. Correct ans - 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 ans - False
T/F: The most common artifact with the ultrasound transducer system for fetal heart rate is
increased variability. Correct ans - True
T/F: All fetal monitors contain a logic system designed to reject artifact. Correct
ans - True
T/F: The monitor should always be tested before starting a tracing, either external or internal mode
and labeled a test. Correct ans - True
T/F: The paper speed on the fetal monitor should always be set at 1cm/min. Correct ans -
False
T/F: Both internal and external monitoring methods are equally accurate means of obtaining the
fetal heart rate and contraction patterns. Correct ans - False
T/F: The external toco is usually placed over the uterine fundus to pick up contractions. Correct ans
- True
T/F: The external toco gives measurable uterine pressure. Correct ans - False
T/F: The fetal spiral electrode can be placed when vaginal bleeding of unknown origin is present. Correct
ans - 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 ans - True
T/F: The spiral electrode is used to more accurately determine the frequency, duration, and intensity of
uterine contractions. Correct ans - False
T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal, not maternal.
Correct ans - False
, T/F: The intrauterine catheter is used to pick up the fetal heart rate. Correct ans
- False
T/F: The internal spiral electrode may pick up the maternal heart rate if the baby has died.
Correct ans - True
T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings. Correct ans -
True
T/F: Variability and periodic changes can be detected with both internal and external monitoring.
Correct ans - True
T/F: Variable decelerations are a result of cord compression. Correct ans - True
T/F: The presence of FHR accelerations in the intrapartum and antepartum periods is a sign of
adequate fetal oxygenation. Correct ans - True
T/F: Variable decelerations are a vagal response. Correct ans - 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 ans
- True
T/F: The fetal heart rate baseline can be determined during periods of marked variability.
Correct ans - False
T/F: Anything that affects maternal blood flow (cardiac output) can affect the blood flow through
the placenta. Correct ans - True
T/F: Variable decelerations are the most frequently seen fetal heart rate deceleration pattern in labor.
Correct ans - True
T/F: Minimal variability is always an indicator of hypoxia and a Cesarean section is indicated.
Correct ans - 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
d. Oxygen
e. Stop oxytocin infusion Correct ans - b. Change maternal position
Etiology of a baseline FHR of 165bpm occurring for the last hour can be:
