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

The most prevalent risk factor associated with fetal death before the onset of labor is:
a. Low socioeconomic status
b. Fetal malpresentation
c. Uteroplacental insufficiency
d. Uterine anomalies Correct Answer-c. Uteroplacental insufficiency

d. Gestational age Correct Answer-a. Vibroacoustic stimulation
T/F: Umbilical cord influences that can alter blood flow include true knots, hematomas, and number of
umbilical vessels. Correct Answer-True
T/F: Low amplitude contractions are not an early sign of preterm labor. Correct Answer-False
T/F: Corticosteroid administration may cause an increase in FHR accelerations. Correct Answer-False
T/F: Corticosteroid administration may cause an increase in FHR. Correct Answer-True
T/F: Contractions cause an increase in uterine venous pressure and a decrease in uterine artery
perfusion. Correct Answer-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
