A pregnant client at 36 weeks gestation presents to the labor and delivery unit with a sudden gush of clear fluid from the vagina 2 hours ago. The client reports no contractions but feels decreased fetal movement. Vital signs are stable, and the fetal heart rate shows minimal variability with occasional variable decelerations. What is the nurse's priority action?
1Perform a sterile speculum examination to confirm rupture of membranes
2Position the client in left lateral position and administer oxygen✓ 정답
3Prepare the client for immediate cesarean delivery
4Obtain a clean-catch urine specimen for analysis
해설
With PROM and FHR changes (minimal variability, variable decelerations), priority is optimizing fetal oxygenation by left lateral positioning and oxygen. Sterile speculum exam (1) delays intervention, cesarean (3) is premature without further assessment, and urine analysis (4) is not urgent.
Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing action for a patient with Premature Rupture of Membranes (PROM) at term (36 weeks) who presents with concerning Fetal Heart Rate (FHR) patterns. The core issue is the potential for fetal compromise indicated by decreased fetal movement, minimal variability, and variable decelerations. These signs suggest possible umbilical cord compression or uteroplacental insufficiency. The nurse's immediate goal is to improve fetal oxygenation and perfusion while preventing further complications like cord prolapse.
Answer Rationale: Key Point! The priority action is to improve fetal oxygenation. Left lateral positioning displaces the uterus off the maternal great vessels (aorta and inferior vena cava), improving venous return, cardiac output, and ultimately uteroplacental blood flow. Administering oxygen via face mask increases maternal oxygen saturation, which can improve fetal oxygen levels. This is a non-invasive, immediate intervention that addresses the root cause of the abnormal FHR patterns (potential hypoxia) before proceeding with diagnostic or definitive procedures.
Distractor Analysis:
Watch out for confusion! Option ① (Sterile speculum exam) is an important diagnostic step to confirm PROM and assess for cord prolapse, but it is not the immediate priority when the fetus shows signs of compromise. Performing an exam could delay life-saving interventions and, if cord prolapse is present, might worsen compression.
Option ③ (Prepare for cesarean) is a potential outcome, but it is premature. The nurse must first implement interventions to improve the fetal status. The decision for an immediate cesarean delivery would be made by the provider after further assessment and if resuscitative measures (like position change and oxygen) fail to correct the FHR pattern.
Option ④ (Urine specimen) is unrelated to the acute presentation. While a Urinary Tract Infection (UTI) can be a risk factor for PROM, collecting a urine sample does not address the immediate threat of fetal hypoxia.
Related Concepts: This scenario integrates knowledge of intrapartum fetal monitoring, the nursing process (assessment and intervention), and prioritization using ABCs (Airway, Breathing, Circulation). For the fetus, the "airway" and "oxygenation" are managed indirectly through the mother. The principles of maternal resuscitation improving fetal status are critical in obstetric emergencies.
Concept Summary
Concept
Key Takeaway
Premature Rupture of Membranes (PROM)
Rupture of amniotic sac before onset of labor. Risk: infection (chorioamnionitis), cord prolapse, fetal compromise.
FHR Variability & Decelerations
Minimal variability and variable decelerations are non-reassuring signs indicating potential fetal hypoxia/acidosis.
Priority Nursing Action
When FHR is non-reassuring: Position (left lateral), Stop oxytocin, Administer O2, Notify provider, Consider IV fluid bolus.
Cord Prolapse
Obstetric emergency. Cord presents before fetal presenting part. Signs: severe variable decelerations, palpable cord on exam. Intervention: Knee-chest position, manual elevation of presenting part, prepare for STAT cesarean.
Side-by-Side Comparison!
FHR Pattern
Causes
Nursing Implications
Variable Decelerations
Umbilical cord compression (e.g., from oligohydramnios after PROM).
Change maternal position (left/right lateral, knee-chest), Administer O2, Consider amnioinfusion if ordered.
Improve placental perfusion: Left lateral position, IV fluids, Correct hypotension, Administer O2.
Early Decelerations
Head compression (normal finding during descent).
Benign pattern. No intervention needed. Continue monitoring.
Anatomy, Physiology & Pharmacology Points
Physiology: The left lateral position relieves pressure on the maternal inferior vena cava, preventing supine hypotensive syndrome and maximizing blood flow to the placenta.
Pathophysiology: PROM leads to loss of amniotic fluid, which can cause umbilical cord compression (variable decels) and increases the risk of ascending infection.
Monitoring: Minimal FHR variability indicates decreased fetal central nervous system activity, often due to hypoxia, sleep cycle, or medications.
Memory Tips
Mnemonic for FHR Interventions: "Position, Oxygen, Fluids, Notify" (POFN).
Think: When the baby is in trouble (non-reassuring FHR), give it air and room (O2 and position change) first.
Priority Rule: In obstetrics, stable mom + compromised baby = interventions aimed at improving fetal status are often the priority.
High-Frequency NCLEX Topics
This integrates several high-yield NCLEX areas: Prioritization, Fetal Assessment, and Obstetric Emergencies. You must know the significance of different FHR patterns and the corresponding immediate, independent nursing actions. NCLEX loves to test the nurse's ability to act before the provider arrives.
Watch Out for Question Variations!
If the question adds "and the nurse sees the umbilical cord protruding from the vagina", the priority becomes knee-chest position and manual elevation to relieve pressure, preparing for an immediate cesarean delivery (cord prolapse emergency).
If the question states "fever and uterine tenderness" with PROM, the priority shifts to administering antibiotics for suspected chorioamnionitis while also monitoring the fetus.
If FHR is absent (no variability, no accelerations, recurrent late or variable decels), the priority is preparing for emergency delivery.
Nursing Clinical Practice GuideClinical Scenario: You are the nurse in triage. A 36-week pregnant patient, Maria, arrives stating her "water broke" in a gush at home. She is anxious and reports the baby hasn't been moving as much. You place her on the monitor. The FHR baseline is 150s, but the tracing shows minimal variability and occasional variable decelerations down to 80 bpm. Her vital signs are BP 118/74, HR 88, SpO2 98% on room air.
Nursing Intervention Strategy:
Immediate Action (First 60 seconds): Call for help/alert the provider while simultaneously:
Verbally instruct and assist Maria to roll onto her left side.
Apply a non-rebreather oxygen mask at 10-15 L/min.
Increase the IV fluid rate (if an IV is present) with a bolus of Lactated Ringer's as per protocol.
Assessment & Communication:
Reassess the FHR tracing. Has the variability improved? Have the decelerations resolved?
Perform a sterile speculum examination only if the FHR recovers and it is safe to do so, checking for cord prolapse and confirming ROM.
Document the time of ROM, characteristics of fluid, FHR patterns before and after interventions, and all actions taken.
Ongoing Care & Preparation:
Continue continuous electronic fetal monitoring.
Monitor maternal temperature every 2 hours for signs of infection.
Prepare for the likelihood of induction of labor or cesarean section, as delivery is often indicated for term PROM, especially with non-reassuring status.
Patient Safety and Precautions:
Contraindication: Do NOT perform a digital cervical exam if PROM is suspected or confirmed unless the patient is in active labor and delivery is imminent. This increases the risk of infection and could precipitate cord prolapse.
Medication Caution: If oxytocin (Pitocin) is ordered for induction, monitor closely for uterine hyperstimulation, which can worsen fetal hypoxia.
Key Monitoring: Watch for signs of chorioamnionitis (maternal fever >100.4°F, fetal tachycardia, uterine tenderness, foul-smelling amniotic fluid).
Nursing Procedure & Medication FlowProcedure: Administering Oxygen to a Laboring Patient
Explain the procedure to the patient: "Maria, I'm going to give you some oxygen to help give your baby a boost."
Apply a non-rebreather mask, ensuring the reservoir bag inflates.
Set the flow rate to 10-15 L/min.
Assess patient comfort and oxygen saturation via pulse oximeter (target SpO2 >95%).
Re-evaluate the FHR tracing within 2-3 minutes for improvement.
Document the time oxygen started, flow rate, patient response, and FHR changes.
A Word from Your Senior Nurse
"In the whirlwind of labor and delivery, your calm, quick thinking is everything. That FHR monitor is your direct line to the baby. When you see those variable decels and minimal variability, your hands should almost automatically reach to turn the patient and grab the O2 mask. We buy time for the baby and information for the provider. Remember, you are the one at the bedside 24/7—your actions in those first critical minutes directly impact outcomes. Study these protocols until they're second nature, so in clinicals or on the NCLEX, choosing the priority action feels instinctive, not like a guess."
Premature Rupture of Membranes — Rupture of the amniotic sac (chorioamniotic membranes) before the onset of labor. At term (≥37 weeks), it is often followed by spontaneous labor. Preterm PROM (<37 weeks) carries risks of prematurity, infection, and cord compression.
Variable Decelerations — Abrupt, visually apparent decreases in the fetal heart rate (FHR) below baseline. The deceleration is variable in duration, depth, and timing relative to contractions. They are typically caused by umbilical cord compression.
Fetal Heart Rate (FHR) Variability — Fluctuations in the baseline FHR that are irregular in amplitude and frequency. It reflects a balanced interaction between the fetal sympathetic and parasympathetic nervous systems. Minimal or absent variability can indicate fetal sleep, CNS depression, or hypoxia.
Left Lateral Position — A positioning intervention where the pregnant patient lies on her left side. This displaces the uterus off the maternal inferior vena cava and aorta, improving venous return, cardiac output, and uteroplacental blood flow. It is a first-line intervention for non-reassuring fetal status.
Cord Prolapse — An obstetric emergency where the umbilical cord descends through the cervix ahead of the fetal presenting part. It is often associated with PROM, abnormal fetal presentation, or a high presenting part. It causes cord compression, leading to severe, prolonged variable decelerations and fetal hypoxia.
