A 32-year-old woman at 34 weeks gestation presents to the emergency department with sudden onset of severe abdominal pain and vaginal bleeding. Assessment reveals a rigid, tender abdomen and fetal heart rate of 90 bpm. The nurse suspects abruptio placentae. What is the priority nursing intervention?

In abruptio placentae with fetal bradycardia and maternal hemorrhage, immediate cesarean delivery is the priority to prevent fetal death and maternal complications like DIC. Other interventions are supportive but secondary to emergency delivery.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a critical obstetric emergency: Abruptio placentae (Placental abruption). This is the premature separation of a normally implanted placenta from the uterine wall before delivery of the fetus. The pathophysiology involves hemorrhage into the decidua basalis, which can lead to concealed or revealed bleeding, uterine irritability, and compromised uteroplacental blood flow. The key clinical triad is painful vaginal bleeding, uterine tenderness/hypertonicity, and fetal distress. In this case, the signs are severe: sudden severe pain, rigid/tender abdomen, vaginal bleeding, and a fetal heart rate (FHR) of 90 bpm (severe fetal bradycardia; normal is 110-160 bpm). This indicates profound fetal hypoxia and imminent risk of fetal demise.

Answer Rationale: Key Point! The priority in a case of suspected severe placental abruption with signs of maternal shock and fetal distress is preparation for immediate delivery. The goal is to save both the mother and the fetus. At 34 weeks, the fetus is viable. A cesarean delivery is the fastest route to achieve delivery in this unstable scenario. The nurse's role is to initiate emergency protocols: notify the obstetrician and surgical team, prepare the operating room, and facilitate rapid transfer. This intervention directly addresses the root cause—the separated placenta—and is the definitive treatment to stop further hemorrhage and fetal compromise.

Distractor Analysis:
• Watch out for confusion! Option ①: Performing a vaginal exam is contraindicated in suspected placenta previa or significant abruption. It can provoke catastrophic hemorrhage by disturbing the placenta or clots. A digital exam should only be done in a controlled setting (e.g., delivery room) if placenta previa has been ruled out by ultrasound.
• Option ②: While pain management is important for maternal comfort, it is not the priority in a life-threatening emergency. Administering analgesics, especially opioids, could mask clinical signs of worsening shock or depress the already compromised fetus.
• Option ④: Positioning in Trendelenburg (head down) is generally not recommended for pregnant patients as it can compromise maternal respiratory status due to pressure from the gravid uterus on the diaphragm and major vessels. The priority is left lateral recumbent position to improve uteroplacental perfusion, but even that is secondary to preparing for immediate delivery in this critical scenario.

Related Concepts: This scenario highlights the ABC (Airway, Breathing, Circulation) priority framework applied to obstetrics. Maternal circulation is compromised by hemorrhage, and fetal circulation is compromised by placental separation. The intervention (cesarean delivery) is the definitive action to restore circulation for both. Other supportive measures include establishing large-bore IV access for fluid/blood resuscitation, administering oxygen, and continuous monitoring of maternal vital signs and fetal heart rate.

Concept Summary • Abruptio Placentae: Painful separation of placenta. Presents with dark vaginal bleeding, constant abdominal pain, rigid uterus, fetal distress.
• Placenta Previa: Painless separation. Presents with bright red, painless vaginal bleeding, soft non-tender uterus. (Key differential diagnosis!)
• Priority Intervention: Stabilize mother (IV, O2, monitor) → Prepare for immediate delivery (often cesarean) for severe cases with fetal distress/maternal instability.
• Major Complication: Disseminated Intravascular Coagulation (DIC) due to release of thromboplastin from the damaged placenta.

Side-by-Side Comparison!

Feature	Abruptio Placentae	Placenta Previa
Pain	Severe, constant abdominal/back pain	Painless bleeding (may have contractions)
Bleeding	Dark, may be concealed or revealed	Bright red, painless, recurrent
Uterus	Firm, rigid, tender, hypertonic	Soft, non-tender
Fetal Status	Often distressed (bradycardia, late decels)	Usually normal unless major hemorrhage
Vaginal Exam	Contraindicated until previa ruled out	Absolutely contraindicated
Delivery Mode	Often emergency cesarean	Scheduled cesarean (if complete previa)

Anatomy, Physiology & Pharmacology Points • Pathophysiology: Hemorrhage into decidua basalis → formation of retroplacental clot → separation → loss of placental surface area for gas/nutrient exchange → fetal hypoxia. Uterine tetany occurs due to irritation from blood.
• Fetal Heart Rate (FHR): Normal range is 110-160 bpm. Bradycardia (

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in Labor & Delivery. A patient arrives as described. She is pale, diaphoretic, clutching her abdomen, and terrified. Her partner is equally anxious.

Nursing Intervention Strategy:
1. Immediate Assessment & Action (First 2 minutes):
• Shout for help. Activate the obstetric emergency team (OB, anesthesia, NICU, OR staff).
• Position: Assist to left lateral tilt to optimize venous return and placental flow while preparing for transport.
• Monitor: Apply continuous external fetal monitor (EFM). The FHR tracing will likely show bradycardia with minimal variability.
• Access: Establish two large-bore IV lines (16- or 18-gauge) for rapid fluid resuscitation. Draw stat labs: CBC, coagulation panel (PT/PTT, fibrinogen, D-dimer), type and crossmatch for 4+ units of blood.
• Oxygen: Apply non-rebreather mask at 10-15 L/min to maximize maternal and fetal oxygenation.
2. Preparation for OR (Next 5 minutes):
• Communication: Notify the charge nurse, OB physician, and anesthesia. Relay critical info: "34 weeks, suspected severe abruption, FHR 90, maternal unstable."
• Patient Preparation: Quickly explain the need for emergency surgery. Obtain informed consent if possible. Insert Foley catheter to monitor urine output (key indicator of perfusion).
• Transport: Safely and swiftly transfer the patient to the operating room with monitoring and oxygen in place.
3. Post-Delivery Care: Anticipate the need for massive transfusion protocol (MTP) due to risk of DIC and ongoing hemorrhage. Monitor for uterine atony after delivery.

Patient Safety and Precautions:
• Absolute Contraindication: NO vaginal or cervical exams until placenta previa is definitively ruled out by ultrasound (if time permits) or in the controlled environment of the OR.
• Medication Caution: Avoid sedatives or opioids that can further depress the fetus. Tocolytic agents (to stop labor) are contraindicated as they can mask signs of shock and delay definitive treatment.
• Monitoring: Continuously assess for signs of worsening shock (tachycardia, hypotension, tachypnea, decreased urine output, altered mental status) and DIC (oozing from IV sites, petechiae).

Nursing Procedure & Medication Flow Emergency Cesarean Preparation Flow:
1. Alert Team → 2. IV Access & Labs → 3. Apply Monitors & O2 → 4. Brief Patient/Family → 5. Foley Insertion → 6. Rapid Transport to OR.
Medication Anticipation:
• In OR: Anesthetic agents (often general anesthesia for speed), uterotonics like Oxytocin (Pitocin) or Methylergonovine (Methergine) after delivery to contract the uterus.
• Post-op: Analgesics, antibiotics, possibly blood products (Packed RBCs, Fresh Frozen Plasma, Platelets, Cryoprecipitate).

A Word from Your Senior Nurse "In moments like these, your calm, decisive action is everything. You are the coordinator of the emergency response. You don't have time to do everything yourself, but you must know what needs to be done and delegate effectively. Remember, in obstetrics, you are caring for two patients, but the mother's stability is paramount for fetal survival. Trust your assessment: severe pain + rigid uterus + fetal bradycardia = a ticking time bomb. Your rapid escalation and preparation for surgery can literally save two lives. This is why we drill on emergency protocols—so when the real thing happens, muscle memory takes over."
