Prolapsed Umbilical Cord

NCLEX Review Guide: Prolapsed Umbilical Cord

Understanding Prolapsed Umbilical Cord

Definition and Types

  • Prolapsed umbilical cord occurs when the umbilical cord slips down through the cervix alongside or ahead of the presenting fetal part, causing cord compression and potential fetal hypoxia.
  • Occult prolapse involves cord compression without visible cord protrusion, while overt prolapse presents with visible cord at the introitus or protruding from the vagina.

Memory Aid: "CORD"

  • Compression leads to hypoxia
  • Occult vs Overt types
  • Raise hips immediately
  • Delivery must be expedited

Risk Factors and Assessment

High-Risk Situations

  • Malpresentation (breech, transverse lie) and multiple gestation increase risk due to poor fetal part fit in pelvis.
  • Polyhydramnios, premature rupture of membranes, and preterm labor create conditions where cord can slip past presenting part.
  • Cephalopelvic disproportion and grand multiparity contribute to inadequate fetal engagement.

Clinical Scenario

A 32-year-old G3P2 client at 36 weeks gestation with breech presentation experiences sudden rupture of membranes. FHR drops from 140 to 80 bpm with variable decelerations. Vaginal exam reveals pulsating cord at cervix.

Assessment Findings

  • Sudden onset of severe variable decelerations or bradycardia following rupture of membranes indicates potential cord prolapse.
  • Palpable pulsating cord on vaginal examination confirms overt prolapse requiring immediate intervention.
  • Fetal heart rate patterns show variable decelerations, bradycardia, or loss of variability indicating fetal compromise.

Emergency Management

Immediate Interventions

  1. Position client in knee-chest or Trendelenburg position to relieve cord compression by gravity.
  2. Insert sterile gloved fingers into vagina to elevate presenting part off the compressed cord until delivery.
  3. Cover exposed cord with sterile saline-soaked gauze to prevent drying and maintain cord temperature.
  4. Administer oxygen at 8-10 L/min via face mask to maximize maternal and fetal oxygenation.
  5. Prepare for immediate cesarean delivery as this is typically the fastest delivery method.

Key Points

  • Never attempt to push the cord back into the uterus
  • Maintain continuous pressure on presenting part until delivery
  • This is an obstetric emergency requiring immediate action
  • Document time of occurrence and interventions performed

Commonly Confused Concepts

Prolapsed Cord Nuchal Cord Cord Entanglement
Cord precedes fetus Cord around fetal neck Cord wrapped around body parts
Immediate emergency May resolve spontaneously Usually manageable during delivery
Requires position changes Monitor FHR patterns Careful delivery technique

Quick Differentiation

Prolapsed cord = Emergency positioning
Nuchal cord = Monitor and manage
Cord entanglement = Careful delivery

Study Tips and Memory Aids

NCLEX Success Strategies

  • Remember "FIRST" priorities: Face mask oxygen, Insert fingers to elevate, Raise hips, Sterile saline gauze, Transport to OR.
  • Key phrase: "Gravity is your friend" - use positioning to reduce cord compression.
  • Never choose answers involving pushing cord back, removing fingers from vagina, or delaying delivery.

Critical Thinking Points

  • Prolapsed cord questions often test prioritization skills
  • Look for sudden FHR changes after membrane rupture
  • Emergency cesarean is usually the correct delivery method
  • Continuous manual elevation is maintained until delivery

Quick Check

Scenario: FHR drops to 70 bpm after ROM, cord visible at introitus. What is the FIRST action?

Answer: Position client in knee-chest position and insert sterile gloved fingers to elevate presenting part.

Common Pitfalls

  • Don't confuse with other cord complications - prolapsed cord requires immediate emergency positioning.
  • Never attempt to reposition the cord - focus on relieving compression through maternal positioning.
  • Don't remove fingers from vagina once manual elevation is established until delivery occurs.
  • Avoid choosing tocolytics - delivery should be expedited, not delayed.

Self-Assessment Checklist

  • ☐ I can identify risk factors for cord prolapse
  • ☐ I understand emergency positioning techniques
  • ☐ I know the priority interventions in correct order
  • ☐ I can differentiate cord prolapse from other cord issues
  • ☐ I understand why cesarean delivery is usually required

You've got this! Remember that prolapsed cord questions test your ability to prioritize emergency interventions. Focus on immediate positioning and manual elevation - these are your key to NCLEX success! 🌟
