질문 # 78
The black pattern represents the heart rate pattern for Baby A. The blue pattern represents the heart rate pattern for Baby B. A possible etiology of the baseline fetal heart rate of Baby A is:
정답：C
설명：
Comprehensive and Detailed Explanation From NCC-Aligned Sources:
The black tracing (Baby A) demonstrates:
* Baseline ~170-175 bpm
* Moderate variability
* No recurrent decelerations
This is fetal tachycardia.
NCC physiology guidelines list common causes of fetal tachycardia:
* Maternal fever / infection (chorioamnionitis)
* Maternal dehydration
* Maternal anxiety
* Maternal hyperthyroidism
* Fetal infection
* Certain medications (terbutaline, illicit stimulants)
Why the other options are incorrect:
* A. Fetal positioning does not influence baseline heart rate.
* C. Magnesium sulfate typically lowers fetal baseline and variability-it does not cause tachycardia.
Thus, the most likely etiology is infection.

질문 # 79
A woman has been 5 cm dilated for the past 3 hours. The tracing shown has developed over the last 30 minutes. The best initial course of action is to:
정답：A
설명：
Comprehensive and Detailed Explanation From Exact Extract-Based NCC C-EFM References:
The fetal heart rate tracing demonstrates recurrent deep variable decelerations with a rapid drop in FHR, a V-shaped pattern, and slow return to baseline. These are classic signs of cord compression. According to NCC, AWHONN, Miller, Menihan, and Simpson, recurrent variable decelerations require immediate intrauterine resuscitative interventions before any decision regarding operative birth.
NCC-aligned intervention steps include:
* Maternal repositioning (first-line for cord compression)
* Reducing or stopping oxytocin if infusing
* IV fluid bolus
* Amnioinfusion (if appropriate and recurrent deep variables persist)
* Oxygen only if other measures fail (per NCC/AWHONN updated guidance)
The cervix has remained unchanged at 5 cm for 3 hours (a prolonged latent or early active labor pattern), but the fetal tracing shows Category II-recurrent variable decelerations. Category II dictates corrective action, not immediate delivery unless it progresses to Category III.
Cesarean birth (option C) is reserved for:
* Persistent Category III
* Failure of intrauterine resuscitation
* Proven fetal intoleranceNone of these conditions have been met yet.
Thus, the correct initial management is B. Perform intrauterine resuscitative measures.

질문 # 80
Maternal fever can cause fetal tachycardia because the increased maternal temperature:
정답：C
설명：
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.

질문 # 81
This fetal heart rate tracing is from a woman in the second stage of labor. This tracing is best interpreted as:
정답：A
설명：
Comprehensive and Detailed Explanation From NCC-Aligned Sources:
The tracing shows the classic features of variable decelerations:
* Abrupt onset (<30 seconds from baseline to nadir)
* Rapid drop followed by a rapid recovery
* Significant variability in shape, depth, and timing
* "Shouldering"-brief accelerations before or after the deceleration, typical of cord compression
* The decelerations vary in appearance and timing relative to contractions In second stage, this pattern is extremely common due to:
* Recurrent cord compression during descent
* Maternal pushing
* Reduced amniotic fluid with advancing labor
Why the other options are incorrect:
A). Intermittent late decelerations
* Late decelerations are uniform, smooth, begin after the contraction peak, and recover after the contraction ends.
* This tracing shows abrupt, variable-shaped, non-uniform decels # NOT late decels.
C). Wandering baseline
* A wandering baseline is a slowly fluctuating, low-amplitude, smooth, preterminal pattern.
* This tracing shows an identifiable baseline with variability and clear decelerations, not wandering baseline.
Thus, the tracing is most consistent with variable decelerations.

질문 # 82
The fetal heart rate tracing shown is consistent with
정답：A
설명：
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.
