A pregnant client at 34 weeks gestation presents to the labor and delivery unit reporting a sudden gush of clear fluid from the vagina 2 hours ago. Which assessment finding would be the nurse's priority concern?
1Maternal temperature of 99.2°F (37.3°C)
2Fetal heart rate of 140 beats per minute
3Umbilical cord prolapse with fetal heart rate dropping to 80 beats per minute✓ 정답
4Amniotic fluid that tests positive for ferning
해설
Umbilical cord prolapse with fetal bradycardia (80 bpm) is an obstetric emergency requiring immediate intervention to prevent fetal hypoxia and death. Other findings (mild maternal fever, normal FHR, positive ferning) are less urgent.
Core Nursing ExplanationKey Concept Analysis: This question tests the nurse's ability to prioritize care in a patient with Premature Rupture of Membranes (PROM) at 34 weeks. The core theme is recognizing and responding to an obstetric emergency. When membranes rupture, especially with a sudden gush, the primary risks are cord prolapse and chorioamnionitis (intra-amniotic infection). The nurse must immediately assess for signs of fetal compromise, which indicate a life-threatening situation.
Answer Rationale: Key Point!Umbilical cord prolapse is a critical, time-sensitive emergency. When the cord descends through the cervix ahead of the presenting part (often after a gush of fluid), it can become compressed between the fetal body and the maternal pelvis. This compression obstructs blood flow, leading to severe fetal bradycardia (a heart rate of 80 bpm is dangerously low; normal is 110-160 bpm). This finding represents an immediate threat to fetal life and is the absolute top priority for nursing intervention.
Distractor Analysis:
Option 1 (Maternal temp 99.2°F/37.3°C): A mild elevation could be an early sign of infection (chorioamnionitis), which is a serious concern in PROM. However, it is not an immediate life threat like cord prolapse. Infection management is urgent but allows for a slightly longer response time (e.g., administering antibiotics).
Option 2 (FHR 140 bpm): This is a normal fetal heart rate. While reassuring, it does not change the fact that the nurse must first rule out or address emergencies. A normal finding is never the priority concern when an abnormal, life-threatening one is present.
Option 4 (Positive ferning): This test confirms that the fluid is indeed amniotic fluid, which is diagnostic for Rupture of Membranes (ROM). While an important assessment, confirming the diagnosis is secondary to assessing for immediate complications like cord prolapse or fetal distress.
Related Concepts: The nursing priority follows the ABC (Airway, Breathing, Circulation) principle, adapted for the fetus. In this scenario, fetal circulation (via the umbilical cord) is compromised. Immediate interventions for cord prolapse include calling for help, placing the mother in a Trendelenburg or knee-chest position to relieve pressure on the cord, administering oxygen, and preparing for an emergency cesarean delivery.
Concept Summary
Term
Description & Implication
Premature Rupture of Membranes (PROM)
Rupture of amniotic sac before onset of labor. Risk of infection (chorioamnionitis) and cord prolapse increases.
FHR < 110 bpm. Sign of fetal hypoxia/distress. A rate of 80 bpm indicates severe compromise.
Ferning Test
Microscopic pattern confirming amniotic fluid. Diagnostic, not a priority over assessing fetal status.
Chorioamnionitis
Infection of amniotic fluid and membranes. Sign: maternal fever, tachycardia, uterine tenderness. Treated with antibiotics.
Side-by-Side Comparison!
Finding in PROM
Clinical Significance
Nursing Priority
Cord Prolapse + Bradycardia
Immediate threat to fetal life (hypoxia).
HIGHEST PRIORITY. Emergency response required.
Maternal Fever (e.g., 101°F/38.3°C)
Sign of developing infection (chorioamnionitis).
Urgent. Requires prompt assessment, labs, and antibiotic administration.
Normal Fetal Heart Rate
Reassuring sign of fetal well-being.
Continue monitoring but does not indicate an emergency.
Positive Ferning
Confirms rupture of membranes.
Important for diagnosis, but not an acute threat.
Anatomy, Physiology & Pharmacology Points
Physiology: The umbilical cord contains two arteries and one vein, transporting oxygenated blood to the fetus and deoxygenated blood away. Compression disrupts this vital exchange.
Positioning: The Trendelenburg or knee-chest position uses gravity to shift the fetal presenting part (usually the head) upward and off the prolapsed cord.
Pharmacology: In PROM at 34 weeks, corticosteroids (betamethasone) may be given to accelerate fetal lung maturity, and antibiotics (e.g., ampicillin) are given prophylactically to prevent infection. However, these are secondary to managing an acute prolapse.
Memory Tips
PRIORITY Acronym for PROM: Prolapse check first, Relieve pressure (position), Immediate help, Oxygen, Ready for OR, Infection watch, Tocometer on, Yield to fetal status.
Think "Cord First": After any rupture of membranes (ROM), the first thought should be "Could the cord have come down?" followed by an immediate check of the fetal heart rate.
High-Frequency NCLEX Topics
NCLEX heavily tests prioritization and obstetric emergencies. Cord prolapse is a classic "Which finding is most concerning?" or "What should the nurse do first?" question. Remember: Any alteration in fetal heart rate following ROM is a red flag until proven otherwise.
Watch Out for Question Variations!
From Symptom to Action: "The nurse confirms a cord prolapse. What is the first action?" (Answer: Reposition mother to Trendelenburg/knee-chest).
Changing the Gestational Age: At term (37+ weeks) with PROM, the priority may shift to assessing for labor onset and infection, but cord prolapse remains the top acute emergency.
Including Variable Decelerations: A question might present a fetal monitor strip showing variable decelerations after ROM, which can indicate cord compression, testing the same concept.
Nursing Clinical Practice GuideClinical Scenario: You are the nurse in triage. Maria, 34 weeks pregnant, states, "My water broke at home with a big gush." She is anxious but currently comfortable. Your initial assessment reveals clear fluid pooling.
Nursing Intervention Strategy:
Immediate Assessment (First 60 seconds):
Ask the client to remain on the stretcher/bed. Do NOT perform a digital vaginal exam at this point if the presenting part is not engaged, as it may displace the cord or introduce infection.
Apply the external fetal monitor (tocometer and ultrasound transducer) immediately to obtain the FHR and check for contractions.
Visually inspect the perineum for any visible loops of cord. If seen, do not attempt to push it back in.
If FHR is Bradycardic (as in the question):
Call a Code OB/Stat Cesarean immediately. Use the call light and shout for help if needed.
Positioning: With assistance, manually elevate the presenting part by inserting a gloved hand into the vagina to push the fetus off the cord, OR immediately place the mother in a steep Trendelenburg position or have her assume a knee-chest position on the bed.
Oxygen: Apply a non-rebreather mask at 10-15 L/min to maximize maternal-fetal oxygenation.
Prepare for Surgery: The team will rush for an emergency cesarean delivery. Your role is to continue relieving cord pressure, explain procedures quickly to the mother, and support her.
If FHR is Normal (Initial Assessment):
Proceed with a sterile speculum exam (not digital) to visually confirm pooling and possibly collect fluid for ferning/fetal fibronectin tests.
Assess vital signs, including temperature (for infection).
Monitor for signs of labor (contractions).
Initiate protocols for preterm PROM (steroids for lung maturity, antibiotics).
Patient Safety and Precautions:
Watch out for confusion! A digital vaginal exam is contraindicated in suspected PROM if the presenting part is not firmly engaged (floating), due to the risk of causing a cord prolapse or introducing infection.
Document the time of rupture, color, odor, and amount of fluid (meconium-stained fluid is another concern).
Continuous electronic fetal monitoring is standard of care after PROM due to the risk of cord compression.
Nursing Procedure & Medication FlowFor Cord Prolapse Emergency:
1. Shout for Help/Activate Emergency.
2. Position: Knee-chest or Trendelenburg.
3. Oxygen: Apply 100% via non-rebreather.
4. Manual Displacement (if trained): Use sterile glove, maintain pressure until delivery.
5. Transport: Bed to OR.
For Preterm PROM Management (Non-Emergent):
- Medication: Betamethasone 12 mg IM x 2 doses 24 hours apart. Purpose: Accelerate fetal lung maturity.
- Medication: Antibiotics (e.g., Ampicillin + Erythromycin protocol). Purpose: Prolong latency period and prevent GBS (Group B Streptococcus) infection.
- Monitoring: Vital signs q4h, strict I&O, daily labs (WBC), continuous fetal monitoring.
A Word from Your Senior Nurse
"In labor and delivery, seconds count. Your rapid, calm assessment is what stands between a routine admission and a catastrophic outcome. When you hear 'my water broke,' your mental checklist must start with the fetus. Is the heart rate okay? Could the cord be compromised? This isn't just test knowledge—it's a real-life script. On the NCLEX, they are testing your clinical judgment: can you spot the one finding that means 'act now'? In this question, the bradycardia coupled with prolapse is the siren. Everything else is background noise. Master this prioritization, and you'll be ready for both the exam and the delivery room."
Premature Rupture of Membranes — Rupture of the amniotic sac before the onset of labor at any gestational age. Increases risks of infection (chorioamnionitis) and umbilical cord prolapse.
Umbilical Cord Prolapse — An obstetric emergency where the umbilical cord descends through the cervix into or beyond the vagina ahead of the fetal presenting part. Risk of cord compression and fetal hypoxia is high.
Fetal Bradycardia — A fetal heart rate (FHR) below 110 beats per minute. A sign of fetal hypoxia/distress. Severe bradycardia (e.g., 80 bpm) requires immediate intervention.
Chorioamnionitis — Infection of the amniotic fluid, fetal membranes, placenta, and/or decidua. Clinical signs include maternal fever, tachycardia, uterine tenderness, and foul-smelling amniotic fluid.
Trendelenburg Position — A position where the patient's head is lowered and feet are elevated. Used in cord prolapse to use gravity to shift the fetal presenting part cephalad (upward), relieving pressure on the prolapsed cord.
