T/F: The most common artifact with the ultrasound transducer system for fetal
heart rate is increased variability.
True
T/F: All fetal monitors contain a logic system designed to reject artifact.
True
T/F: Fetal arrhythmias can be seen on both internal and external monitor tracings.
True
T/F: Variability and periodic changes can be detected with both internal and
external monitoring.
True
T/F: Variable decelerations are a vagal response.
True
T/F: Variable decelerations are the most frequently seen fetal heart rate
deceleration pattern in labor.
True

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

,The most prevalent risk factor associated with fetal death before the onset of
labor is:
a. Low socioeconomic status
b. Fetal malpresentation

Which of the following conditions is not an indication for antepartum fetal
surveillance?
a. Gestational hypertension

T/F: Umbilical cord influences that can alter blood flow include true knots,
hematomas, and number of umbilical vessels.
True
T/F: Low amplitude contractions are not an early sign of preterm labor.
False
T/F: Corticosteroid administration may cause an increase in FHR accelerations.
False
T/F: Corticosteroid administration may cause an increase in FHR.
True
T/F: Contractions cause an increase in uterine venous pressure and a decrease in
uterine artery perfusion.
True
As a result of the intrinsic fetal response to oxygen deprivation, increased
catecholamine levels cause the peripheral blood flow to decrease while the blood
flow to vital organs increases. These flow changes along with increased
catecholamine secretions have what effect on fetal blood pressure and fetal heart
rate?
A. Increase BP and increase HR
B. Increase BP and decrease HR
C. Decrease BP and increase HR
D. Decrease BP and decrease HR
B. Increase BP and decrease HR
