NCC Certified - Electronic Fetal Monitoring 認定 EFM 試験問題 (Q46-Q51):

質問 # 46
Stimulation of the vagus nerve in a healthy fetus will cause:

正解：B

解説：
Comprehensive and Detailed Explanation From NCC-Aligned Sources:
Vagal stimulation is part of the parasympathetic nervous system, which causes:
* Slowing of the fetal heart rate (FHR)
* Rapid but temporary changes in HR
* Seen with head compression, scalp stimulation, or fetal movement
NICHD/NCC physiology explains:
* Vagus nerve activation # acetylcholine release # slowed SA node firing # decrease in FHR
* This mechanism is responsible for early decelerations during labor due to head compression.
Why the incorrect answers are wrong:
* B. Increased cardiac contractility # sympathetic effect, not vagal.
* C. Increased fetal blood pressure # also a sympathetic effect.
Correct answer: A. Decreased fetal heart rate

質問 # 47
A woman at 36-weeks gestation comes in because of uterine contractions radiating to the back. She has no insurance. In accordance with the Emergency Medical Treatment and Active Labor Act (EMTALA), she is obligated to be:

正解：A

解説：
Comprehensive and Detailed Explanation From Exact Extract-Based NCC C-EFM References:
NCC's Professional Issues domain includes EMTALA obligations for pregnant patients. EMTALA requires that ANY individual who presents to a hospital emergency department-regardless of insurance status- must receive:
* A Medical Screening Examination (MSE)
* Stabilization of any identified emergency medical condition (including labor)
* No transfer unless the patient requests it or the hospital cannot provide necessary stabilizing care This patient reports contractions at 36 weeks, which qualifies as a potential emergency medical condition until ruled out by the medical screening exam.
Correct obligations per EMTALA:
* She must NOT be transferred solely due to lack of insurance (option C).
* She does NOT need to be admitted unless labor is confirmed (option A).
* She must receive a medical screening examination and stabilization (option B).
Thus, the correct answer is B. Stabilized and receive a medical screening examination.

質問 # 48
A woman at 39-weeks gestation is in early labor, 2-3 cm dilated, 85% effaced, and -2 station. Based on the fetal heart rate tracing shown, what is the most appropriate first intervention?

正解：A

解説：
Comprehensive and Detailed Explanation From Exact Extract-Based NCC C-EFM References:
The tracing shows significant artifact, periods of signal loss, and abrupt changes inconsistent with physiologic fetal patterns. This is typical of poor signal quality, not actual fetal decelerations. In early labor at -2 station, external FHR monitoring often loses contact due to fetal position and maternal movement.
NCC and AWHONN emphasize the following when artifact is present:
* Correct signal quality before interpreting the tracing.
* Troubleshooting steps include:- Adjusting transducer location- Ensuring adequate ultrasound gel- Repositioning the mother- Checking for maternal heart rate contamination Why the other options are incorrect:
* B. IV fluid bolus - Indicated for hypotension or late decelerations, not for artifact.
* C. Terbutaline - Used for tachysystole with fetal intolerance; there is no tachysystole shown.
Thus, the correct first step is A. Adjust the fetal monitor.

質問 # 49
The ratio of oxyhemoglobin to the total amount of hemoglobin available is called oxygen

正解：B

解説：
Comprehensive and Detailed Explanation From Exact Extract NCC-Recommended Sources Oxygen saturation refers to the percentage of hemoglobin binding sites occupied by oxygen. NCC physiology resources, including Simpson & Creehan and Creasy & Resnik, define oxygen saturation as the
"ratio of oxyhemoglobin to total hemoglobin"-the same definition used in fetal oxygenation discussions.
Oxygen affinity refers to hemoglobin's tendency to bind oxygen (related to the oxyhemoglobin dissociation curve).
Oxygen carrying capacity refers to the total amount of oxygen hemoglobin can transport, independent of current saturation.
AWHONN and Menihan emphasize that fetal oxygenation assessment is dependent on understanding oxygen saturation, not affinity or carrying capacity, when discussing fetal hypoxemia and gas exchange.

質問 # 50
The pattern on the fetal heart rate tracing shown is likely due to

正解：B

解説：
Comprehensive and Detailed Explanation From Exact Extract Sources:
The tracing demonstrates an abrupt-onset, sharp, V-shaped deceleration, occurring simultaneously with or slightly after a contraction-classic for variable decelerations, which are caused by umbilical cord compression.
According to AWHONN Fetal Heart Monitoring Principles & Practices, variable decelerations are defined by:
* "Abrupt decreases in FHR below baseline of at least 15 bpm, lasting at least 15 seconds and less than 2 minutes."
* "Most commonly associated with umbilical cord compression, whether transient or recurrent." Physiology reference (Simpson & Miller, Pocket Guide):
* Compression of the umbilical vein causes a brief acceleration.
* Compression of the umbilical arteries triggers a vagal response, producing a rapid deceleration.
* This creates the characteristic sharp 'V', 'U', or 'W' shape on the monitor.
Placental insufficiency (Choice B) produces late decelerations, which are gradual, not abrupt.
Fetal head compression (Choice A) produces early decelerations, which mirror contractions and have a gradual pattern.
Thus, the tracing is most consistent with variable decelerations caused by umbilical cord compression.
