C-EFM EXAM PREP Questions and Answers
1. During an non stress test, a significant increase in the Fetal heart
rate is observed following fetal movement. This FHR characteristic is
best described as
A. Baseline Variability
B. An acceleration
C. A deceleration
D. Sinusoidal pattern
ANS B An Acceleration
Rational
Accelerations are transient increases in the FHR above the baseline rate, with fetal movement, indicating fetal
wellbeing.
Baseline variability refers to fluctuations in the FHR around the baseline level,
decelerations are decreases in FHR and
a sinusoidal pattern is a smooth, wave-like undulating pattern in FHR, not related to fetal movement.
2. A pregnant patient's ultrasound reveals a single umbilical artery. What
poten- tial outcome is most associated with this finding?
A. Increased risk of chromosomal anomalies
B. Unaffected pregnancy outcome
C. Decreased fetal movement

, D. Enhanced placental function
ANS A. Increased risk of chromosomal anomalies
Rational
The presence of a single umbilical artery can be associated with an increased risk of congenital anomalies/
abnormalities. Further evaluation is warranted in these situations
3. In the context of maternal-fetal oxygen exchange the role of the
placenta includes
A. Oxygen production
B. Facilitating gas exchange by simple diffusion
C. Active transport of oxygen from fetus to mother
D. Filtering maternal antibodies from reaching the fetus.
ANS B. Facilitating gas exchange by
simple dittusion
Rational
The placenta assists in the exchange of Oxygen and CO2 between maternal and fetal blood supplies by
means
of simple dittusion.
It cannot create oxygen. It allows for transfer of antibodies from mom to baby..
