A 32-year-old gravida 2, para 1 client at 34 weeks gestation presents to the labor and delivery unit with sudden onset of severe abdominal pain and vaginal bleeding. The client reports the pain started suddenly about 30 minutes ago and describes it as constant and severe. She has a history of cocaine use but denies recent use. Physical examination reveals a rigid, tender abdomen and dark red vaginal bleeding. Vital signs are: BP 90/60 mmHg, HR 120 bpm, RR 24/min. The fetal heart rate shows late decelerations with decreased variability. What is the nurse's highest priority action?

This scenario describes placental abruption, a life-threatening obstetric emergency requiring immediate delivery. The fetal heart rate pattern indicates severe fetal compromise, making immediate cesarean delivery the highest priority to save both maternal and fetal lives. Other options are supportive but secondary to delivery.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing action for a patient with suspected Placental abruption (Abruptio placentae). Abruption is the premature separation of the placenta from the uterine wall before delivery. It is an obstetric emergency characterized by Key Point! the classic triad of painful vaginal bleeding, uterine tenderness/rigidity, and fetal distress. The pathophysiology involves hemorrhage into the decidua basalis, leading to a concealed or revealed bleed, which compromises both maternal circulation (risk of hypovolemic shock and DIC) and fetal oxygenation.

Answer Rationale: The correct answer is Prepare for immediate cesarean delivery. The patient's presentation (sudden severe pain, rigid tender abdomen, dark red bleeding, hypotension, tachycardia) is highly indicative of a severe abruption. The fetal heart rate (FHR) tracing showing late decelerations and decreased variability signifies Key Point! acute, severe fetal compromise due to uteroplacental insufficiency. In the context of a viable fetus (34 weeks) with signs of maternal instability and fetal distress, the definitive treatment is expedited delivery, most often via cesarean section, to save both lives. This is the ultimate intervention that addresses the root cause.

Distractor Analysis:
Watch out for confusion! Option ② (Administer IV fluid bolus) is a critical supportive measure for maternal hypovolemia but is not the highest priority when the fetus is in immediate danger and the cause (the separated placenta) requires surgical resolution. Fluids are given concurrently while preparing for surgery.
• Option ③ (Position in left lateral position) is a standard intervention to improve uteroplacental perfusion by relieving aortocaval compression. However, in a severe abruption with a rigid uterus and fetal distress, repositioning alone is insufficient to reverse the crisis.
• Option ④ (Obtain blood for coagulation studies) is important because abruption can trigger Disseminated Intravascular Coagulation (DIC). However, this is a diagnostic/laboratory step. The clinical picture already demands immediate action; waiting for lab results would delay life-saving intervention.

Related Concepts: This scenario highlights the ABC (Airway, Breathing, Circulation) priority framework with a maternity twist. While stabilizing the mother's circulation is vital, the presence of a viable fetus in distress creates a dual-patient priority. Often, the quickest way to save the mother (by stopping the hemorrhage) is to deliver the fetus and placenta. Differentiate this from Placenta previa, which presents with painless, bright red bleeding and usually requires monitoring and planned delivery, not immediate surgery. Concept SummaryPlacental Abruption: Painful bleeding + uterine tenderness/rigidity + fetal distress. Risk factors: Hypertension, trauma, cocaine use, smoking, advanced maternal age.
Fetal Heart Rate (FHR) Findings in Distress: Late decelerations (uteroplacental insufficiency), decreased variability (acidosis), bradycardia.
Maternal Risks: Hypovolemic shock, Couvelaire uterus, DIC.
Nursing Priority: Recognize the emergency, prepare for immediate delivery (often C-section), provide simultaneous supportive care (IV access, fluids, oxygen, monitoring). Side-by-Side Comparison!

Anatomy, Physiology & Pharmacology PointsPathophysiology: Hemorrhage at the decidua basalis causes placental separation. This reduces surface area for gas/nutrient exchange (fetal hypoxia) and can lead to maternal coagulopathy due to release of thromboplastin into circulation.
Fetal Monitoring: Late decelerations are U-shaped dips in FHR that start after the peak of a contraction, indicating inadequate placental perfusion and fetal hypoxia.
Drug Alert: Cocaine is a vasoconstrictor and a major risk factor for abruption. It causes hypertension and reduced placental blood flow. Memory TipsAbruption = PAIN: Painful, Acute, Immediate delivery, Not normal uterus (rigid).
Previa = PAINLESS: Painless, Assessment first (ultrasound), Intervention may be delayed, No tenderness. High-Frequency NCLEX Topics NCLEX loves testing priority-setting in obstetric emergencies. You must differentiate between actions that are "important" and those that are "immediate life-saving." The rule: If the fetus is viable and in distress due to a correctable problem (like abruption), Key Point! preparation for delivery is almost always the top priority. Supportive measures (fluids, oxygen, positioning) are done while preparing for the definitive treatment. Watch Out for Question Variations! • Instead of asking for the priority action, it might ask: "The nurse anticipates preparing which medication?" (Answer might be Rhogam if Rh-negative, or corticosteroids for fetal lung maturity if delivery can be delayed slightly—which it can't in this case).
• It might describe a less acute scenario: "Client at 36 weeks with mild spotting and occasional cramping." Then the priority shifts to assessment (vital signs, FHR monitoring, ultrasound) and notification of the provider rather than immediate surgery.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse in Labor & Delivery. A patient is rushed in by her partner. She is pale, diaphoretic, clutching her abdomen, and crying in pain. She has visible dark red blood on her gown. Her partner says, "The pain came out of nowhere!"

Nursing Intervention Strategy:
1. Immediate Action & Assessment: While calling for help and the provider, apply oxygen via non-rebreather mask at 10-15 L/min. Place the patient in a left lateral tilt if possible, but do not delay transport to OR. Apply two large-bore IV catheters (14- or 16-gauge) and start isotonic crystalloid (Normal Saline or Lactated Ringer's) wide open. Continuously monitor BP, HR, O2 saturation, and FHR.
2. Communication & Preparation: Alert the charge nurse, obstetrician, anesthesiologist, and neonatal team (NICU). State clearly: "Possible severe abruption, mother unstable, fetus in distress." Begin preoperative preparation: informed consent (if possible), skin prep, Foley catheter insertion, and ensure blood products are available (type and crossmatch for 4 units).
3. Ongoing Monitoring & Support: Monitor for signs of developing DIC: check for bleeding from IV sites, gums, or oozing. Assess urine output (indicator of renal perfusion). Provide clear, calm explanations to the patient and family.

Patient Safety and Precautions: Never perform a vaginal exam if placenta previa is suspected. In abruption, a gentle speculum exam may be done by the provider to assess cervical dilation, but a digital exam is contraindicated if previa cannot be ruled out. Rapid fluid resuscitation is key, but be vigilant for signs of fluid overload, especially if the patient has underlying cardiac issues. Nursing Procedure & Medication FlowProcedure: Preparing for Emergency Cesarean Section:
1. Ensure consent is obtained (by provider).
2. Administer preoperative antibiotics (e.g., cefazolin) as ordered, typically within 60 minutes before incision.
3. Perform abdominal skin prep with chlorhexidine solution.
4. Insert indwelling urinary catheter to keep bladder empty.
5. Assist anesthesia provider with rapid-sequence induction.
6. Have neonatal resuscitation equipment (warmer, suction, ambu bag) ready in OR.
Medication/Vitals Focus: Titrate IV fluids to maintain systolic BP >90 mmHg. Anticipate orders for blood products (packed RBCs, fresh frozen plasma for coagulation factors). Monitor for uterine atony and hemorrhage after delivery. A Word from Your Senior Nurse "In moments like these, your ability to act quickly and think clearly under pressure saves lives. Placental abruption is one of the most terrifying obstetric emergencies because it threatens two patients at once. Your first instinct might be to 'fix' the mom's low BP with fluids, but you must see the bigger picture: the baby is suffocating. The fastest way to stop the internal bleeding and save the baby is to get them out. In clinical practice and on the NCLEX, always ask yourself: 'What is the problem that, if not fixed right now, will lead to death or severe harm?' Here, it's the separated placenta. That's why surgery is priority #1. You've got this!"
