NCC EFM PRACTICE COMPREHENSIVE STUDY
GUIDE WITH SOLUTIONS
◉ 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.
Answer: True
◉ T/F: The spiral electrode is used to more accurately determine the
frequency, duration, and intensity of uterine contractions..
Answer: False
◉ T/F: The heart rate from a well-applied fetal spiral electrode can
only be fetal, not maternal..
Answer: False
◉ T/F: The intrauterine catheter is used to pick up the fetal heart
rate..
Answer: False
◉ T/F: The internal spiral electrode may pick up the maternal heart
rate if the baby has died..
Answer: True
,◉ T/F: Fetal arrhythmias can be seen on both internal and external
monitor tracings..
Answer: True
◉ T/F: Variability and periodic changes can be detected with both
internal and external monitoring..
Answer: True
◉ T/F: Variable decelerations are a result of cord compression..
Answer: True
◉ T/F: The presence of FHR accelerations in the intrapartum and
antepartum periods is a sign of adequate fetal oxygenation..
Answer: True
◉ T/F: Variable decelerations are a vagal response..
Answer: True
◉ T/F: Late decelerations have a gradual decrease in FHR (onset to
nadir 30 seconds) and are delayed in timing with the nadir of the
deceleration occurring after the peak of the contraction..
Answer: True
,◉ T/F: The fetal heart rate baseline can be determined during
periods of marked variability..
Answer: False
◉ T/F: Anything that affects maternal blood flow (cardiac output)
can affect the blood flow through the placenta..
Answer: True
◉ T/F: Variable decelerations are the most frequently seen fetal
heart rate deceleration pattern in labor..
Answer: True
◉ T/F: Minimal variability is always an indicator of hypoxia and a
Cesarean section is indicated..
Answer: False
◉ What is your first intervention in management of a patient
experiencing variable decelerations?
a. Immediate delivery
b. Change maternal position
c. No treatment indicated
d. Oxygen
, e. Stop oxytocin infusion.
Answer: b. Change maternal position
◉ Etiology of a baseline FHR of 165bpm occurring for the last hour
can be:
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.
Answer: c. 2, 3 and 4
◉ What is the most probable cause of recurrent late decelerations?
a. Utero-placental insufficiency
b. Head compression
c. Cord compression
d. Maternal position change.
Answer: a. Utero-placental insufficiency
