Case Study — Maternal-Newborn
Umbilical Cord Prolapse NGN Case Study
A Next Gen NCLEX-style unfolding case. Read each step, commit to your own answer — out loud or on paper — and only then reveal ours. The six steps mirror the NCSBN Clinical Judgment Measurement Model exactly as the exam tests it.

Educational use only. This case is a simplified learning exercise, not a delivery protocol — real obstetric emergencies follow provider orders and facility policy. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.
The Scenario
1420, labor & delivery: Ms. Okoro, 29, is a G2P1 at 39 weeks in active labor, 6 cm dilated, fetus at a high station (−2). She has been comfortable on continuous fetal monitoring with a reassuring tracing. The provider performs an amniotomy (artificial rupture of membranes); a large gush of clear fluid returns.
Seconds Later
- Fetal heart rate drops abruptly from a baseline of 140 to the 70s and stays there
- The monitor shows deep, prolonged variable decelerations
- Ms. Okoro is startled: “What’s happening? Is the baby okay?”
- On a quick sterile exam, you feel a pulsating loop of cord ahead of the presenting part
Step 1 — Recognize Cues
Which cues matter most right now? Flag them before revealing.
▸Reveal answer
The alarm cues: abrupt fetal bradycardia (140 → 70s) and deep prolonged variable decelerations immediately after rupture of membranes, plus a palpable, pulsating loop of cord ahead of the presenting part. Together these are cord prolapse until proven otherwise.
The setup cues (why she was at risk): a high, unengaged presenting part (−2 station) at the time of amniotomy leaves room for the cord to slip down with the fluid gush.
The trap: spending time re-checking the monitor or repositioning the transducer. Variable decels that appear the instant the water breaks demand a vaginal exam, not troubleshooting the equipment.
Step 2 — Analyze Cues
What explains this picture? Connect the cues.
▸Reveal answer
Umbilical cord prolapse (strongly supported): ROM + high station + immediate variable decels + a palpable cord = the cord is compressed between the presenting part and the pelvis, cutting off fetal oxygen. Variable decelerations are the classic FHR signature of cord compression.
Why not the others: placental abruption usually brings pain and bleeding; uterine rupture brings tearing pain and loss of station (and she has no scar); amniotic fluid embolism causes maternal collapse, not an isolated fetal deceleration. The palpable cord settles it.
Urgency: this is a time-critical fetal emergency — minutes of sustained cord compression cause hypoxic injury.
Step 3 — Prioritize Hypotheses
What drives your next action?
▸Reveal answer
1. Cord prolapse with fetal compromise — the priority, and it is already confirmed by the palpable cord. Everything now aims at restoring fetal oxygenation and getting to delivery.
2. Prepare for emergent cesarean — unless delivery is truly imminent vaginally (it is not, at 6 cm), cesarean is the route.
NGN logic: a confirmed, lethal, time-sensitive fetal emergency outranks everything — you act before you finish charting or explaining.
Step 4 — Generate Solutions
What should happen in the next minutes?
▸Reveal answer
Relieve the cord compression (the core intervention): keep your gloved hand in the vagina and lift the presenting part off the cord, and place the mother in knee-chest or Trendelenburg (or left-lateral with hips elevated) to use gravity.
Call for help and mobilize the team: activate the obstetric emergency response; notify the provider; ready the OR and neonatal team.
Support oxygenation: high-flow oxygen by non-rebreather; stop oxytocin if infusing; a tocolytic may be ordered to reduce contractions; start/verify IV access.
Do NOT: push the cord back in; keep any exposed cord moist with warm saline gauze and handle it minimally.
Step 5 — Take Action
Sequencing question: you are alone in the room when you feel the cord. What is your very first action — and how do you get help without leaving the patient?
▸Reveal answer
Keep your hand in place and lift the presenting part off the cord immediately — do not remove it to make a phone call. Call for help using the room’s emergency call system/pull cord or by summoning anyone within earshot; have that person alert the provider and the OR while you maintain elevation and reposition the mother into knee-chest.
The judgment inside it: your hand is the intervention — it stays until the cesarean team takes over in the OR. Everything else (oxygen, stopping oxytocin, IV, consent, transport) is delegated to arriving staff. You will physically go to the OR with your hand still elevating the presenting part.
Step 6 — Evaluate Outcomes
Reassessment: with your hand elevating the presenting part and the mother in knee-chest on high-flow oxygen, the fetal heart rate recovers into the 120s–130s within a minute and stays there during transport. What tells you the intervention is working, and what is not yet resolved?
▸Reveal answer
Working: the FHR recovery is the real-time proof that cord compression is relieved — the fetus is being oxygenated again. Maintained recovery during repositioning and transport confirms it.
Not resolved: the definitive fix is delivery. The compression can recur the instant pressure returns, so the hand stays and the team proceeds to emergent cesarean; the neonatal team stands ready for resuscitation.
The loop: evaluation feeds back to action — if the FHR had NOT recovered, you would escalate further and expedite delivery even faster.
Debrief — The Pattern to Keep
- ✦Variable decels or bradycardia the instant the water breaks = rule out cord prolapse with a vaginal exam — don't troubleshoot the monitor.
- ✦The intervention is your hand: lift the presenting part off the cord and keep it there until delivery.
- ✦Reposition to knee-chest or Trendelenburg to add gravity; give O2; stop oxytocin — never push the cord back in.
- ✦Get help without leaving the patient — your hand can't come off the cord to make a call.
- ✦The fetal heart rate recovery is the outcome measure; delivery (usually emergent cesarean) is the definitive fix.
