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.

Normal umbilical arterial values per NCC/AWHONN/Menihan:

pH: 7.20–7.30

PaCO₂: 45–55 mmHg

HCO₃: 20–24 mEq/L

Base deficit: 0 to –5 (normal to mild respiratory changes)

This sample shows:

pH 7.25 → normal

Base deficit –4 → no metabolic acidosis

HCO₃ normal

Slightly elevated PaCO₂, consistent with mild respiratory influence but still normal

PaO₂ 20 mmHg is normal for cord arterial blood

This profile is not acidotic (acidosis requires pH <7.10 and base deficit ≥12).

It also does not indicate hypoxia, which would present with metabolic acidosis.

Therefore: Normal.

NCC-recommended physiologic texts (AWHONN, Menihan, Simpson, Creasy & Resnik) explain that variable decelerations are caused by umbilical cord compression. This process occurs in a three-step sequence, well known in fetal monitoring physiology:

Umbilical vein occlusion occurs first → decreases fetal venous return → brief fetal acceleration (a compensatory sympathetic response).

Umbilical artery occlusion follows → increases fetal systemic vascular resistance → variable deceleration as vagal stimulation lowers the fetal heart rate.

Release of compression → post-deceleration acceleration may occur.

Thus, an acceleration immediately before a variable deceleration represents the initial compression of the umbilical vein, not a hypoxic response. This is a normal physiologic response to transient cord compression, often described in AWHONN and Menihan's physiologic explanation of “shoulders” around variable decelerations.

Oligohydramnios can contribute to cord compression but does not explain accelerations preceding the deceleration. A “hypoxic reflex” would not produce a pre-deceleration acceleration.

Therefore, the correct physiologic cause is:

Umbilical vein occlusion.

During amnioinfusion, NCC emphasizes monitoring for uterine overdistention, which can lead to uterine hypertonus, uterine rupture, or placental separation. The primary way to evaluate overdistention is by measuring baseline uterine pressure via IUPC.

Rising resting tone (>20–25 mmHg) indicates accumulating fluid and risk.

Stopping the infusion intermittently allows recalibration and assessment of uterine baseline pressure.

Contraction pattern (option B) is important but not the primary safety parameter.

Pain (option C) is nonspecific and not a reliable indicator of uterine overdistention.

Thus, the infusion is stopped to assess baseline uterine pressure.
