A laboring client at 38 weeks gestation suddenly experiences severe variable decelerations on the fetal heart rate monitor. Upon vaginal examination, the nurse palpates the umbilical cord protruding from the cervix. What is the nurse's immediate priority action?
1Position the client in knee-chest or Trendelenburg position and apply upward pressure to the presenting part✓ 정답
2Immediately clamp the umbilical cord to prevent further prolapse
3Cover the exposed cord with sterile saline-soaked gauze and monitor fetal heart rate
4Prepare the client for immediate vaginal delivery to expedite birth
해설
Positioning in knee-chest or Trendelenburg and applying upward pressure relieves cord compression, the priority in umbilical cord prolapse. Other actions (clamping, covering cord, vaginal delivery) are incorrect or secondary.
Core Nursing ExplanationKey Concept Analysis: This question tests the immediate nursing priority for a life-threatening obstetric emergency: Umbilical Cord Prolapse. This occurs when the umbilical cord slips through the cervix ahead of the fetal presenting part (usually the head). The prolapsed cord becomes compressed between the fetal head and the maternal pelvis, leading to severe Variable Decelerations on the fetal heart rate (FHR) monitor due to compromised blood flow and oxygen supply to the fetus. The priority is to relieve pressure on the cord immediately to prevent fetal hypoxia, brain damage, or death.
Answer Rationale: Key Point! The correct answer is to position the client in a knee-chest or Trendelenburg position and apply upward pressure to the presenting part. This action uses gravity to shift the fetal presenting part (head) away from the pelvis, relieving compression on the umbilical cord. The upward manual pressure (often done with a sterile-gloved hand during a vaginal exam) further lifts the presenting part off the cord. This is the immediate, life-saving intervention to restore umbilical blood flow while preparing for an emergency cesarean delivery.
Distractor Analysis:
Watch out for confusion! Option ② (Immediately clamp the cord) is dangerous. Clamping a prolapsed cord before delivery completely cuts off the fetus's only oxygen supply, leading to immediate fetal demise. Clamping is only done after the baby is born.
Option ③ (Cover cord with gauze and monitor) is an important but secondary action. While keeping the cord moist and sterile is necessary to prevent drying and infection, it does not address the immediate threat of cord compression and fetal hypoxia. Monitoring alone is insufficient during an active emergency.
Option ④ (Prepare for immediate vaginal delivery) is incorrect because with a prolapsed cord and a high presenting part, vaginal delivery is often impossible or would take too long, risking severe fetal compromise. The definitive treatment for a prolapsed cord is an emergency cesarean section.
Related Concepts: This scenario is a classic example of applying the ABC (Airway, Breathing, Circulation) priority framework to fetal well-being. The cord is the fetus's lifeline for circulation and oxygenation. Relieving cord compression is analogous to establishing an airway. The nursing process here is rapid: Assess (identify prolapse and FHR decels) → Diagnose (risk for impaired fetal gas exchange) → Plan/Implement (immediate positioning to relieve pressure and prepare for C-section) → Evaluate (monitor FHR for improvement).

Side-by-Side Comparison!
Obstetric Emergency
Key Feature
Immediate Nursing Priority
Umbilical Cord Prolapse
Cord palpable/presenting at cervix. Severe variable decels.
Painful, dark vaginal bleeding; rigid, tender uterus.
Assess maternal-fetal status (vitals, FHR), prepare for emergency delivery.
Uterine Rupture
Sudden, sharp abdominal pain; loss of uterine contour; fetal distress.
Call for help, prepare for immediate laparotomy and hysterectomy.
Shoulder Dystocia
Head delivers, but shoulders are stuck.
Call for help, perform McRoberts maneuver (hyperflex thighs to abdomen).
Anatomy, Physiology & Pharmacology Points
• Pathophysiology: Compression of the umbilical cord vessels (one vein, two arteries) obstructs fetal circulation. The vein (carrying oxygenated blood to fetus) is compressed first, causing hypoxia. This triggers a vagal response, leading to the characteristic Variable Deceleration on the FHR strip.
• Risk Factors: Conditions that prevent the fetal head from snugly fitting into the pelvis: Malpresentation (breech, transverse), Polyhydramnios (excess amniotic fluid), Multiparity (lax uterine muscles), premature rupture of membranes (PROM) with a high presenting part.
• Pharmacology Note: Tocolytics (e.g., Terbutaline) are sometimes used to relax the uterus temporarily if there is a delay in getting to the operating room, but this is a physician order. The nurse's independent action is positioning.
Memory Tips
• Acronym: POP – Prolapsed Cord → Off the cord Pressure → Position change (Knee-chest).
• Visualize: Imagine the baby's head is sitting on a garden hose (the cord). To get water (oxygen) flowing again, you must lift the head off the hose. That's what knee-chest position does!
• Priority Order: 1) Position, 2) Push (upward pressure), 3) Prepare for C-section, 4) Keep cord Protected (moist).
High-Frequency NCLEX Topics
Umbilical cord prolapse is a high-yield topic for NCLEX-RN. The exam tests your ability to:
1. Recognize the signs (severe variable decels + palpable cord).
2. Prioritize the immediate independent nursing action (positioning to relieve pressure).
3. Differentiate between correct emergency actions and harmful or delayed actions (e.g., clamping vs. covering).
Expect questions that combine FHR interpretation with emergency management.
Watch Out for Question Variations!
• Instead of "What is the priority action?", it could be: "The nurse palpates the umbilical cord. Which client position should the nurse initiate?" (Answer: Knee-chest).
• Or: "After initiating the priority intervention for cord prolapse, which action should the nurse take next?" (Answer: Notify the physician/Midwife and prepare for emergency cesarean section).
• The scenario could involve a different risk factor (e.g., "client with ruptured membranes and breech presentation").
Nursing Clinical Practice GuideClinical Scenario: You are the labor & delivery nurse for Maria, G2P1 at 38 weeks. Her membranes ruptured spontaneously 30 minutes ago. While assisting her to the bathroom, she says she feels "something coming out." You quickly help her back to bed, perform a sterile vaginal exam, and feel a pulsating, rope-like structure. You glance at the monitor: the fetal heart rate has dropped from 140 to 60 bpm with a deep, variable deceleration pattern.
Nursing Intervention Strategy:
1Immediate Action (Do Not Leave Client)Yell for help. While keeping your sterile-gloved hand in the vagina, gently apply upward pressure against the fetal presenting part (head) to lift it off the cord.
2PositioningInstruct assistants to immediately place Maria in an exaggerated Trendelenburg position (head down, feet up) or a Knee-Chest position. This uses gravity to pull the fetus back into the uterus.
3Communication & PreparationAs you maintain pressure and position, direct your team:
• "Call the OB stat! We have a cord prolapse."
• "Notify anesthesia and the OR team for an emergency C-section."
• "Bring the fetal monitor to the OR."
4Ongoing CareOnce in position, if possible, cover the exposed cord with sterile, saline-soaked gauze to prevent drying. Continue to monitor FHR for recovery from decelerations.
Patient Safety and Precautions:
• NEVER attempt to push the cord back in. This can cause vasospasm and worsen compromise.
• NEVER clamp or cut the cord.
• Maintain upward pressure and positioning continuously until the moment of delivery in the OR.
• Provide clear, calm explanations to the terrified patient and partner: "We need to move quickly to keep your baby safe. We are taking you for a C-section right now."
Nursing Procedure & Medication FlowProcedure: Responding to Umbilical Cord Prolapse
2Relieve PressureCall for help. Apply upward vaginal pressure. Position client (Knee-chest/Trendelenburg).
3ReportNotify physician/midwife, anesthesia, OR team.
4Rapid TransportTransfer client to OR while maintaining pressure and position. Monitor FHR en route.
5Ready for SurgeryAssist with rapid preoperative preparation (consent, IV, Foley catheter, surgical prep).
Medication Note: Tocolytics like Terbutaline 0.25 mg SQ may be ordered by the physician to relax the uterus. The nurse administers it while monitoring for maternal tachycardia. Oxygen at 10 L/min via non-rebreather mask is always administered to the mother to maximize fetal oxygenation.
A Word from Your Senior Nurse
In obstetrics, seconds count. A prolapsed cord is one of the most nerve-wracking emergencies because you are literally holding the baby's lifeline in your hand (or against your finger). Your knowledge and swift, calm action directly determine the outcome. On the NCLEX, they are testing your clinical judgment under pressure: Can you pick the one action that buys time and saves a life? In the real world, this is why we drill emergency protocols. Remember: Position, Pressure, Prepare. That sequence is your mantra for this scenario. You've got this!
