NEW QUESTION # 27
Usually, the duration of an early deceleration in comparison with the contraction is:
- A. The same
- B. Longer
- C. Shorter
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract-Based NCC C-EFM References:
An early deceleration is defined by NICHD and NCC as a gradual decrease and return of the fetal heart rate associated with uterine contractions. NCC emphasizes that early decelerations are:
* Symmetrical
* Uniform in shape
* Mirror images of the contraction
This means:
* Onset of deceleration = onset of contraction
* Nadir of deceleration = peak of contraction
* Recovery = end of contraction
* Duration of the deceleration # duration of the contraction
Thus, the correct answer is C. The same.

NEW QUESTION # 28
The tracing shown is a:
- A. Category II
- B. Category I
- C. Category III
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract-Based NCC C-EFM References (No URLs):
Interpretation of fetal heart rate (FHR) tracings in the NCC C-EFM exam follows the standardized NICHD three-tier classification, which is fully adopted in NCC's content outline and recommended references such as AWHONN Fetal Heart Monitoring Principles & Practices, Miller's EFM Pocket Guide, Menihan, Simpson' s Perinatal Nursing, and Creasy & Resnik.
Baseline:
The tracing demonstrates an FHR baseline around 145-150 bpm, which falls within the normal range of 110-
160 bpm. NCC references define baseline as the mean FHR rounded to increments of 5 bpm over a 10-minute window.
Variability:
The strip shows minimal variability, with amplitude fluctuations approximately 0-2 bpm.
According to NCC-aligned definitions:
* Moderate variability: 6-25 bpm
* Minimal variability: 1-5 bpm
* Absent variability: undetectable amplitude
This tracing shows minimal variability, not moderate, so it cannot be Category I.
Accelerations:
No accelerations are present. Lack of accelerations alone does not classify the tracing as Category III.
Decelerations:
There are no recurrent late decelerations, no recurrent variable decelerations, and no prolonged decelerations. Without these, and with minimal variability, the tracing does not meet Category III criteria.
Category III criteria (per NICHD/NCC):
Must include at least one of the following:
* Absent variability with recurrent late decelerations
* Absent variability with recurrent variable decelerations
* Absent variability with bradycardia
* Sinusoidal pattern
None of these are present.
Category II criteria (per NICHD/NCC):
Category II includes tracings that are not Category I or III.
Examples specifically listed include:
* Minimal variability
* Absent accelerations after fetal stimulation
* Tachycardia
* Bradycardia without absent variability
* Variable or late decelerations occurring intermittently
Because this tracing shows minimal variability, a normal baseline, no accelerations, and no recurrent decelerations, it fits squarely into Category II.
Therefore, the correct classification is Category II.

NEW QUESTION # 29
Fetal cardiac output is essentially dependent on the fetal:
- A. Baroreceptors
- B. Activity
- C. Heart rate
Answer: C
Explanation:
Comprehensive and Detailed Explanation From NCC-Aligned Sources:
Because the fetal myocardium is immature, it has:
* Limited ability to increase stroke volume
* Limited ability to increase contractility
Therefore, fetal cardiac output (CO) is almost entirely dependent on heart rate.
NCC and AWHONN physiology describe:
* CO = stroke volume × heart rate
* In the fetus, stroke volume is relatively fixed
* Therefore, changes in HR directly affect cardiac output
* Tachycardia # increases CO
* Bradycardia # decreases CO # decreased perfusion and oxygen delivery
Why the other options are incorrect:
* A. Activity does not fundamentally determine CO.
* B. Baroreceptors regulate HR reflexively but are not the primary determinant of cardiac output.
Correct answer: C. Heart rate

NEW QUESTION # 30
A 30-minute tracing with moderate variability, accelerations, and one variable deceleration would be classified as:
- A. Category II
- B. Category I
- C. Category III
Answer: A
Explanation:
Comprehensive and Detailed Explanation From NCC-Aligned Sources:
NICHD/NCC criteria:
Category I must have ALL of the following:
* Baseline 110-160 bpm
* Moderate variability
* No late or variable decelerations
* Early decelerations may be present or absent
* Accelerations may be present or absent
Because this tracing has one variable deceleration, it fails Category I criterion ("no late or variable decelerations").
Category III requires:
* Absent variability with recurrent late decels, recurrent variables, or bradycardia, or
* Sinusoidal pattern
Those findings are not present.
Therefore, any tracing that:
* Has moderate variability and accelerations,
* But includes a variable deceleration, and
* Does not meet Category III criteria
...falls into the Category II (indeterminate) group.
Correct classification: B. Category II.

NEW QUESTION # 31
A woman at 38-weeks gestation is admitted to labor and delivery following a fall down the stairs three hours ago. She started feeling contractions in the ambulance. The fetal heart rate tracing shown is on initial evaluation and represents 25 minutes. This tracing is most consistent with a
- A. category I tracing
- B. category II tracing
- C. category III tracing
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract without any URL or Links According to the NCC C-EFM 2025 Candidate Guide, Pattern Recognition and Intervention requires the candidate to classify fetal heart rate (FHR) patterns using the NICHD 2008 three-tier system, which NCC endorses across all recommended resources (AWHONN Fetal Heart Monitoring Principles and Practices, Menihan Electronic Fetal Monitoring, Simpson & Creasy, Miller's Pocket Guide).
A Category II tracing is defined as "indeterminate" and includes any FHR pattern that is not Category I and not Category III. NCC references indicate that Category II may include:
* Minimal or marked variability
* Absence of accelerations after fetal stimulation
* Recurrent variable decelerations with moderate variability
* Prolonged decelerations lasting 2-10 minutes
* Baseline tachycardia or bradycardia without absent variability
In the tracing provided:
* The baseline FHR is approximately 135-145 bpm, within normal limits.
* Moderate variability is not consistently present; variability is borderline minimal-moderate at times.
* No significant accelerations are seen over the 25-minute evaluation period.
* No recurrent late or prolonged decelerations are present.
* There are occasional subtle variable-type dips, but not enough to meet criteria for Category III.
NCC-endorsed texts (such as AWHONN and Menihan) state that a tracing with minimal variability for less than 40 minutes and without recurrent decelerations is Category II, as it fails to meet the requirements for Category I (must have moderate variability and accelerations absent decelerations) and lacks the criteria for Category III (must have absent variability with recurrent late decels, recurrent variable decels, bradycardia, or sinusoidal pattern).
Therefore, this pattern is indeterminate, consistent with Category II, and requires continued surveillance and evaluation, which aligns with NCC-recommended clinical decision-making competencies.
NEW QUESTION # 32
Prenatal diagnosis shows that a fetus has renal agenesis. During delivery, what type of electronic fetal heart rate pattern is most likely to be seen due to a common complication associated with this syndrome?
- A. Fetal heart block
- B. Late decelerations
- C. Variable decelerations
Answer: C
Explanation:
Comprehensive and Detailed Explanation From NCC-Aligned Sources:
Renal agenesis # severe oligohydramnios (due to absent fetal urine production).
Oligohydramnios causes:
* Cord compression
* Recurrent variable decelerations
* Possible prolonged decels from cord entrapment
This is one of the hallmark FHR complications in renal agenesis.
Why the other options are incorrect:
* A. Heart block - associated with maternal autoimmune antibodies, not renal anomalies.
* B. Late decelerations - associated with uteroplacental insufficiency, not fluid deficiency.
Correct answer: C. Variable decelerations.

NEW QUESTION # 33
The presence of fetal breathing movements on a biophysical profile reflects adequate:
- A. Neurologic function
- B. Pulmonary vasoconstriction
- C. Surfactant levels
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract-Based NCC C-EFM References:
A biophysical profile (BPP) assesses 5 components:
* FHR reactivity
* Fetal breathing movements
* Fetal tone
* Fetal movement
* Amniotic fluid volume
According to NCC/AWHONN, fetal breathing movements are controlled by the fetal central nervous system, specifically brainstem integrity.
Thus, fetal breathing movements signify normal neurologic function, particularly intact CNS and oxygenation.
Why the others are incorrect:
* Pulmonary vasoconstriction is not assessed by BPP.
* Surfactant levels do not correlate directly with fetal breathing movement scores.
Correct answer: A. Neurologic function.

NEW QUESTION # 34
(Full question statement)
Interobserver reliability in interpretation of fetal heart rate tracings is greatest when the tracing is:
- A. Indeterminate
- B. Normal
- C. Abnormal
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract Without Links:
NCC examination standards and AWHONN clearly state that normal Category I patterns have the highest interobserver agreement because they contain objective, easily identifiable components:
* baseline 110-160 bpm
* moderate variability
* absence of late or variable decelerations
* presence or absence of accelerations
Simpson highlights that Category II tracings have poor reliability due to multiple combinations of variability and decelerations, while Category III patterns have higher agreement but occur far less frequently, limiting reliability measures.
Research cited within NCC-endorsed materials confirms that clinicians demonstrate the greatest agreement in identifying normal Category I patterns, making normal the correct answer.
NEW QUESTION # 35
Maternal fever can cause fetal tachycardia because the increased maternal temperature:
- A. Decreases tissue perfusion
- B. Increases fetal metabolism
- C. Inhibits catecholamine release
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract-Based NCC C-EFM References:
Maternal hyperthermia-most commonly from infection-causes a rise in fetal temperature, which increases fetal metabolic rate. The fetus responds by increasing heart rate to meet the increased oxygen demand.
Effects include:
* Increased fetal oxygen consumption
* Enhanced fetal cardiac output
* Resultant tachycardia, often 160-180 bpm
This mechanism is repeatedly outlined in NCC's physiology domain, AWHONN, Menihan, Simpson, and Creasy & Resnik.
Option A is incorrect because maternal fever does not reduce perfusion.
Option C is incorrect because catecholamines are often elevated, not inhibited.
Thus, the mechanism is increased fetal metabolism.

NEW QUESTION # 36
Tachysystole can have a negative effect on fetal oxygenation during labor by
- A. blocking active transport of oxygen to the fetus
- B. interfering with reperfusion of the intervillous space
- C. increasing maternal blood pressure
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract NCC-Recommended Sources NCC-recommended physiology references (AWHONN, Simpson & Creehan, Menihan, Creasy & Resnik) consistently state that the primary mechanism by which tachysystole affects fetal oxygenation is reduced uteroplacental perfusion, specifically through impaired intervillous space reperfusion.
During a normal contraction cycle, the fetus receives oxygen between contractions, when the uterus relaxes and maternal blood re-enters the intervillous space. AWHONN's Fetal Heart Monitoring Principles & Practices explains that tachysystole-defined as more than five contractions in 10 minutes averaged over 30 minutes-shortens or eliminates the relaxation phase, preventing adequate placental reoxygenation.
Simpson & Creehan highlight that "tachysystole decreases uteroplacental blood flow and interferes with replenishment of oxygenated maternal blood in the intervillous space." Menihan emphasizes that fetal hypoxemia in tachysystole results from interrupted perfusion, not from altered oxygen transport or maternal hemodynamic changes. Creasy & Resnik confirm that uterine overactivity reduces intervillous perfusion during contractions and impairs fetal oxygen exchange.
Thus, the physiologic problem is failure of the intervillous space to reperfuse, which compromises fetal oxygenation.

NEW QUESTION # 37
Interventions undertaken to address fetal tachycardia are targeted at maximizing
- A. sympathetic autonomic tone
- B. maternal circulation
- C. uteroplacental perfusion
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract NCC-Recommended Sources Fetal tachycardia is typically caused by maternal fever, dehydration, hypoxia, medications, infection, or fetal stress. AWHONN and Simpson & Creehan emphasize that management focuses on improving oxygen delivery across the placenta, which is governed by uteroplacental perfusion.
Menihan's EFM text states that "interventions for fetal tachycardia must address oxygen transfer by optimizing uteroplacental blood flow," including hydration, reducing uterine activity, maternal repositioning, and treating maternal fever.
Increasing maternal circulation alone is insufficient unless it improves placental blood flow. Enhancing fetal sympathetic tone is not a clinical goal and would worsen tachycardia.
Creasy & Resnik highlight that fetal heart rate abnormalities resolve when uteroplacental perfusion is restored, confirming this as the primary target of intervention.

NEW QUESTION # 38
This tracing demonstrates:
- A. Prolonged deceleration
- B. Category III tracing
- C. Bradycardia
Answer: A
Explanation:
Comprehensive and Detailed Explanation From NCC-Aligned Sources:
A prolonged deceleration is defined by NICHD and NCC as:
* A deceleration lasting #2 minutes but <10 minutes
* Decrease in FHR of #15 bpm
* Can occur with or without uterine contractions
This tracing shows:
* A deep drop in FHR down to ~60-70 bpm
* Duration lasting several minutes
* Recovery back to baseline
* Moderate variability present afterward
Because variability remains present and the tracing does not show:
* Absent variability
* Recurrent late decelerations
* Recurrent variable decelerations with absent variability
* Bradycardia for #10 minutes
...it does not meet criteria for Category III.
It is also not bradycardia, because bradycardia requires:
* Baseline <110 bpm for 10 minutes or longer
Therefore the correct interpretation is a prolonged deceleration.

NEW QUESTION # 39
This fetal heart rate tracing represents:
- A. Prolonged acceleration
- B. Coupling of contractions
- C. Category I tracing
Answer: B
Explanation:
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.

NEW QUESTION # 40
Accelerations that last 10 minutes or more are considered:
- A. Baseline variability
- B. A baseline change
- C. Tachycardia
Answer: B
Explanation:
Comprehensive and Detailed Explanation From NCC-Aligned Sources:
NICHD definitions endorsed by NCC:
* An acceleration lasting #10 minutes is no longer an acceleration
* It is classified as a baseline change
* This also applies to decelerations lasting #10 minutes being considered a new baseline bradycardia Why the incorrect answers are wrong:
* B. Baseline variability # refers to amplitude fluctuations, not duration.
* C. Tachycardia # requires baseline >160 bpm for 10 minutes, but the definition of "acceleration #10 minutes = baseline change" supersedes this.
References:NCC C-EFM Candidate Guide; NICHD Definitions; AWHONN FHMPP.
NEW QUESTION # 41
A woman (G1, P0) at 41-weeks gestation presents to OB triage to rule out labor. Her cervical exam is 1 cm/50%/-2. Membranes are intact. She would like to go home if not in labor. Based on this tracing, which represents the last two hours, the best approach is:
- A. admission to hospital
- B. further observation
- C. discharge to home
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract NCC-Recommended Sources 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.

NEW QUESTION # 42
When monitoring monochorionic-monoamniotic twins, which of the following fetal heart rate patterns would be anticipated?
- A. Baseline tachycardia
- B. Minimal variability
- C. Variable decelerations
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract (NCC-Referenced Sources) Mono-mono twins share a single amniotic cavity, which significantly increases the risk of cord entanglement
, a concept highlighted in AWHONN FHM, Creasy & Resnik Maternal-Fetal Medicine, and Miller's EFM Pocket Guide.
These texts emphasize:
* "Cord entanglement is nearly universal in monoamniotic twins."
* "Variable decelerations are common due to recurrent cord compression." Baseline tachycardia or minimal variability are not expected baseline characteristics, but may appear only in pathologic circumstances.
Thus, variable decelerations are the expected and anticipated FHR pattern in mono-mono twins.
