Introduction
This practice assessment is designed to rigorously evaluate the knowledge and clinical reasoning required for
certification in electronic fetal monitoring. The examination assesses proficiency in interpreting fetal heart rate
tracings, understanding underlying maternal-fetal physiologic mechanisms, and applying evidence-based
interventions to safeguard fetal well-being during the intrapartum period. Candidates must demonstrate the
ability to distinguish reassuring from non-reassuring patterns, recognize evolving fetal compromise, and
communicate critical findings effectively within the interprofessional team. Scenario-based questions challenge
,clinical judgment, adherence to NICHD terminology, and alignment with current AWHONN and ACOG standards.
This 100-question, multiple-choice assessment serves as a definitive preparation tool for the NCC EFM certification
examination and promotes excellence in perinatal clinical practice.
SECTION ONE
Question 1
A nurse is evaluating a fetal heart rate tracing and notes that the baseline is 150 bpm with variability of
approximately 8 to 12 bpm. The tracing shows no decelerations. According to NICHD terminology, this
variability should be classified as:
A. Absent variability
B. Minimal variability
C. Moderate variability
D. Marked variability
🟢 Correct Answer: C
🔴 RATIONALE: NICHD defines moderate variability as an amplitude range of 6 to 25 bpm from the peak to
trough of the FHR fluctuation. An amplitude of 8 to 12 bpm falls squarely within this range. Moderate variability
indicates a well-oxygenated fetal central nervous system with balanced sympathetic and parasympathetic input.
It is the most reassuring variability pattern and is a required criterion for a Category I tracing.
Question 2
,During the active phase of labor, the external tocodynamometer shows contractions occurring every 2 minutes
and lasting 60 to 70 seconds each. The patient reports intense pain. The nurse palpates the uterine fundus and
notes that it feels firm but can be indented slightly at the contraction peak. This palpation finding suggests that
the monitor may be:
A. Accurately reflecting the true intensity of the contractions
B. Underestimating the intensity of the contractions
C. Overestimating the intensity of the contractions
D. Measuring the maternal heart rate instead of contractions
🟢 Correct Answer: B
🔴 RATIONALE: External tocodynamometry measures the change in abdominal wall contour, not direct
intrauterine pressure. A firm uterus at the peak that still allows slight indentation suggests the contraction is
moderately strong, but the tocodynamometer tracing deflection may appear lower than expected due to
maternal adipose tissue, belt placement, or maternal position. An IUPC would be needed for accurate
quantitative measurement of intensity.
Question 3
A laboring patient at 40 weeks gestation has an FHR tracing that shows recurrent decelerations beginning after
the contraction starts, with the lowest point occurring well after the contraction peak, and a slow return to
baseline. The baseline variability is minimal. The nurse correctly identifies this pattern as:
A. Recurrent early decelerations with minimal variability
B. Recurrent variable decelerations with minimal variability
, C. Recurrent late decelerations with minimal variability
D. Intermittent prolonged decelerations with minimal variability
🟢 Correct Answer: C
🔴 RATIONALE: The key distinguishing feature of late decelerations is the timing—the nadir occurs after the
peak of the contraction, and the return to baseline is also delayed. They have a gradual onset and are reflective
of uteroplacental insufficiency. Combined with minimal variability, this is a Category II tracing that requires
prompt evaluation and intervention, as it suggests the fetus may be experiencing hypoxic stress.
Question 4
Which physiologic mechanism best explains the occurrence of early decelerations?
A. Umbilical vein compression causing decreased fetal blood return
B. Fetal head compression causing vagal nerve stimulation
C. Reduced uteroplacental blood flow during contractions
D. Maternal hypotension from epidural anesthesia
🟢 Correct Answer: B
🔴 RATIONALE: Early decelerations are caused by compression of the fetal head during uterine contractions,
particularly as the head descends into the pelvis. This compression stimulates the vagus nerve, which slows the
sinoatrial node firing rate, producing a gradual decrease in heart rate that mirrors the contraction, with the
nadir at the contraction peak. Early decelerations are generally benign and not associated with fetal hypoxia
when variability is normal.
