EFM Exam Dumps - NCC C-EFM Questions and Answers

Comprehensive and Detailed Explanation From Exact Extract NCC-Recommended Sources

The tracing demonstrates a very rapid, highly regular baseline fetal heart rate with minimal beat-to-beat variability—characteristic of fetal supraventricular tachycardia (SVT). NCC-recommended references, including AWHONN’s Fetal Heart Monitoring Principles & Practices, Menihan’s Electronic Fetal Monitoring: Concepts and Applications, Simpson & Creehan’s Perinatal Nursing, and Creasy & Resnik’s Maternal-Fetal Medicine all describe fetal SVT as a sustained tachyarrhythmia usually greater than 200 bpm, narrow-complex, and extremely regular in appearance.

AWHONN teaches that SVT appears as a “tight, rapid, uniform baseline with minimal variability.” Menihan states that “SVT may present on EFM as a nearly straight line due to the rapid, consistent rate with micro-oscillations.” This differs significantly from artifact, which appears disorganized, erratic, and inconsistent in amplitude. Additionally, “half-counting” is a Doppler misinterpretation that records half of an extremely fast fetal rate, usually resulting in a falsely lower heart rate—not the very rapid tracing shown here.

Creasy & Resnik emphasize that SVT is the most common pathological fetal arrhythmia and can lead to fetal compromise if prolonged, making accurate recognition essential. Miller’s Pocket Guide to Fetal Monitoring also identifies SVT as a pattern with a “smooth, fast rhythm lacking normal variability.”

All authoritative NCC-recommended references support that this EFM pattern is consistent with fetal SVT, not artifact or half-counting.

The fetal heart rate tracing shows a normal baseline (120–150 bpm), moderate variability, and no decelerations, consistent with a Category I pattern. According to AWHONN’s Fetal Heart Monitoring Principles & Practices and NCC Perinatal Safety recommendations, a Category I tracing reliably indicates normal fetal acid-base status at the time of assessment and is considered reassuring.

Simpson & Creehan emphasize that in triage, management decisions depend on cervical status, contraction pattern, membrane status, and fetal well-being. With a cervix at 1 cm/50%/-2, intact membranes, and no regular labor pattern, she is not in active or latent labor requiring admission, provided fetal status is reassuring.

Menihan states that a normal tracing lasting two hours with moderate variability supports safe discharge when maternal and fetal assessments are normal. Creasy & Resnik confirm that reassuring fetal testing plus absence of labor is appropriate for outpatient management.

Comprehensive and Detailed Explanation From Exact Extract–Based NCC C-EFM References:

The lower uterine tracing shows a repetitive contraction pattern characterized by pairs of contractions occurring close together, followed by a longer interval. This is known as “uterine contraction coupling.”

Key features confirming coupling:

Two contractions occur back-to-back, separated by only a few seconds.

Then a longer rest period occurs before the next pair.

This pattern persists over several minutes.

FHR remains normal with moderate variability and no decelerations.

Coupling is a uterine activity pattern, not a fetal heart rate abnormality.

Why the other answers are incorrect

A. Category I tracing

While the FHR itself may appear reassuring, the question is explicitly about the pattern shown, which is (per NCC classification) a uterine pattern, not a category designation.

C. Prolonged acceleration

A prolonged acceleration would be a fetal heart rate increase ≥15 bpm lasting ≥2 minutes but <10 minutes.

No such FHR increase appears on the strip.

Thus, the correct interpretation is B. Coupling of contractions.

According to the NCC C-EFM 2025 Exam Content Outline and recommended references such as AWHONN Fetal Heart Monitoring Principles, Simpson & Miller (Fetal Monitoring Text), and Menihan’s EFM Guide, recurrent variable or late decelerations with minimal or moderate variability during the second stage of labor—particularly when the patient has been pushing for ≥2 hours—indicate progressive fetal intolerance of labor.

AWHONN states that when the fetal tracing displays recurrent variable decelerations with ongoing stress from long second stage, the recommended intervention is operative or expedited vaginal birth, provided the fetal station is at +2 or lower. AWHONN and Simpson emphasize that reducing oxytocin is insufficient when the tracing demonstrates ongoing significant decelerations during active pushing with adequate descent.

The NCC blueprint within Pattern Recognition & Intervention emphasizes:

Identifying worsening recurrent decelerations

Acting when fetal tolerance is decreasing

Prioritizing timely intervention when the second stage exceeds standard limits with a non-reassuring tracing

Because she is fully dilated, vertex at +2, and tracing shows recurrent decelerations during pushing, the evidence-based next step is expediting birth, typically via operative vaginal delivery.

Comprehensive and Detailed Explanation From Exact Extract (NCC-Referenced Sources)

According to the NCC C-EFM Exam Outline and AWHONN Fetal Heart Monitoring (5th & 6th ed.), recurrent variable decelerations with progressive reduction in variability reflect worsening fetal hypoxia, especially when coupled with prolonged second stage and arrest of descent.

AWHONN and Menihan both state that:

“Minimal variability with recurrent decelerations indicates inability of the fetus to maintain adequate oxygenation.”

“Failure of descent in second stage with non-reassuring patterns requires operative delivery.”

Creasy & Resnik emphasize that operative vaginal birth requires:

(1) fetal head at +2 station or below,

(2) favorable position,

(3) reassuring fetal status.

Here, the fetus is OP, descent has arrested, and FHR is non-reassuring. This contraindicates vacuum extraction.

Therefore, the appropriate management under NCC competencies is cesarean birth.

Comprehensive and Detailed Explanation From NCC-Aligned Sources:

The single best indicator of fetal oxygenation and neurologic integrity is:

Moderate baseline variability

Variability reflects:

Normal autonomic regulation

Adequate fetal oxygenation

Intact neurologic pathways

Absence of decelerations is helpful but not as predictive.

Baseline FHR (e.g., 140–150) is normal, but baseline alone does not confirm well-being.

Correct answer: C. Presence of variability

Comprehensive and Detailed Explanation From Exact Extract–Based NCC C-EFM References:

This tracing demonstrates a normal, reassuring fetal heart pattern that is technically categorized as Category I, indicating normal fetal acid–base status. Before any decision regarding discharge or induction, NCC emphasizes correct assessment of the tracing quality, fetal status, and uterine activity.

Key Tracing Characteristics

Baseline:Approximately 135–145 bpm, well within the normal range of 110–160 bpm.

Variability:The strip shows moderate variability (6–25 bpm), the strongest indicator of adequate fetal oxygenation per NCC, AWHONN, and NICHD.

Accelerations:Several accelerations are present—another reassuring feature of normal fetal well-being.

Decelerations:No variable, late, or prolonged decelerations are present.

Uterine Activity:The lower channel shows poor recording quality and inconsistent signal—suggesting the toco is not capturing contractions well, not that the patient is contracting excessively or not at all.

Correct interpretation per NCC:

NCC emphasizes distinguishing between physiologic assessment and technical artifact.

The fetal tracing is completely reassuring.

The only abnormality is the poor uterine activity signal, a common triage occurrence due to:

Toco placement

Maternal body habitus

Positioning

Low contraction intensity in early labor

Thus, the correct next step is to optimize equipment (reposition the toco, adjust belt, palpate contractions) and continue to monitor.

Why the other options are incorrect:

B. Admit for induction – NOT indicated

There is no evidence of fetal compromise.

No indication for induction is present (pain score 4/10, reassuring FHR, term pregnancy).

NCC emphasizes avoiding unnecessary interventions.

C. Discharge to home – NOT yet appropriate

You cannot safely discharge a patient with a poorly monitored contraction pattern.

Adequate assessment requires confirming uterine activity—after fixing the toco.

Therefore, the appropriate action is:

A. Adjust tocotransducer and continue to monitor.
