,Which of the following factors can have a negative effect on uterine blood
flow?
a. Hypertension
b. Epidural
c. Hemorrhage
d. Diabetes
e. All of the above - correct ans:e. 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 ans:b.
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 ans:a. 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 ans:g. 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 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
