b. Epidural
c. Hemorrhage
d. Diabetes
e. All of the
... [Show More] above - correct answeree. All of the above
How does the fetus compensate for decreased maternal circulating volume?
a. Increases cardiac output by increasing stroke volume.
b. Increases cardiac output by increasing it's heart rate.
c. Increases cardiac output by increasing fetal movement. - correct answereb. Increases
cardiac output by increasing it's heart rate.
Stimulating the vagus nerve typically produces:
a. A decrease in the heart rate
b. An increase in the heart rate
c. An increase in stroke volume
d. No change - correct answerea. A decrease in the heart rate
What initially causes a chemoreceptor response?
a. Epidurals
b. Supine maternal position
c. Increased CO2 levels
d. Decreased O2 levels
e. A & C
f. A & B
g. C & D - correct answereg. C & D
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 answereb. Decreases baseline
T/F: Oxygen exchange in the placenta takes place in the intervillous space. - correct
answereTrue
T/F: The parasympathetic nervous system is a cardioaccelerator. - correct
answereFalse
T/F: Baroreceptors are stretch receptors which respond to increases or decreases in
blood pressure. - correct answereTrue
T/F: There are two electronic fetal monitoring methods of obtaining the fetal heart rate:
the ultrasound transducer and the fetal spiral electrode. - correct answereTrue
T/F: Variability can be determined with the fetoscope. - correct answereFalse
NCC EFM Certification
T/F: Because the ultrasound transducer and toco transducer are sealed units, they can
be dipped in warm water to make cleaning easier. - correct answereFalse
T/F: The most common artifact with the ultrasound transducer system for fetal heart rate
is increased variability. - correct answereTrue
T/F: All fetal monitors contain a logic system designed to reject artifact. - correct
answereTrue
T/F: The monitor should always be tested before starting a tracing, either external or
internal mode and labeled a test. - correct answereTrue
T/F: The paper speed on the fetal monitor should always be set at 1cm/min. - correct
answereFalse
T/F: Both internal and external monitoring methods are equally accurate means of
obtaining the fetal heart rate and contraction patterns. - correct answereFalse
T/F: The external toco is usually placed over the uterine fundus to pick up contractions.
- correct answereTrue
T/F: The external toco gives measurable uterine pressure. - correct answereFalse
T/F: The fetal spiral electrode can be placed when vaginal bleeding of unknown origin is
present. - correct answereFalse
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 answereTrue
T/F: The spiral electrode is used to more accurately determine the frequency, duration,
and intensity of uterine contractions. - correct answereFalse
T/F: The heart rate from a well-applied fetal spiral electrode can only be fetal, not
maternal. - correct answereFalse
T/F: The intrauterine catheter is used to pick up the fetal heart rate. - correct
answereFalse
T/F: The internal spiral electrode may pick up the maternal heart rate if the baby has
died. - correct answereTrue
T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings. -
