Core Nursing Explanation
Key Concept Analysis: This question tests the priority nursing intervention for a patient with suspected
Abruptio placentae (Placental abruption) showing signs of maternal and fetal compromise. Abruptio placentae is the premature separation of the placenta from the uterine wall, which can lead to concealed or revealed hemorrhage, uterine irritability, and compromised fetal oxygenation. The scenario presents a
Key Point! true obstetric emergency with classic signs: severe pain, rigid abdomen, vaginal bleeding, maternal hypotension (
BP 90/60 mmHg), tachycardia (
HR 120 bpm), and ominous fetal heart rate (FHR) findings (
90 bpm with minimal variability).
Answer Rationale: The priority is
Prepare for immediate cesarean delivery and notify the operating room. This is because the primary problem is a compromised placenta that can no longer sustain the fetus, coupled with ongoing maternal hemorrhage. The fetal bradycardia indicates severe hypoxia, and the maternal vital signs suggest hypovolemic shock. The definitive treatment to stop the hemorrhage and potentially save the fetus is rapid delivery. All other actions are supportive but must not delay the primary intervention of emergency delivery.
Distractor Analysis:
- Option 1 (Administer oxygen): While oxygen administration is a supportive measure to increase maternal-fetal oxygenation, it does not address the root cause—the separated placenta. It is a secondary intervention.
- Option 2 (IV access and fluids): Establishing IV access and starting fluid resuscitation is critical for managing maternal hypovolemia and shock. However, in this acute, life-threatening scenario with fetal distress, the nurse would initiate this while simultaneously preparing for surgery. It is a concurrent, not the singular priority, action.
- Option 3 (Left lateral position): Positioning on the left side improves venous return and placental perfusion by taking pressure off the inferior vena cava. This is a correct and important intervention for fetal well-being, but again, it is a supportive measure that does not resolve the underlying catastrophic event.
Related Concepts: This scenario integrates knowledge of obstetric emergencies, fetal monitoring interpretation, and the nursing principle of prioritizing interventions that address the
Key Point! life-threatening problem for both mother and fetus. The nurse's role is to recognize the emergency, initiate supportive care, and facilitate the definitive treatment without delay.
Concept Summary
| Concept | Key Points |
| Abruptio Placentae | Premature separation of placenta. Causes pain, bleeding, uterine rigidity, fetal distress, maternal shock. |
| Fetal Compromise Signs | FHR < 110 bpm (Bradycardia), minimal/absent variability, late decelerations. |
| Maternal Shock Signs (Hypovolemic) | Hypotension, tachycardia, tachypnea, cool/clammy skin, anxiety. |
| Priority Nursing Action | Facilitate immediate delivery (often cesarean) to stop hemorrhage and rescue fetus. |
| Supportive Interventions | O2, large-bore IVs, fluids, left lateral position, continuous monitoring, emotional support. |
Side-by-Side Comparison!
| Placenta Previa | Abruptio Placentae |
| Pain: Usually painless | Pain: Sudden, severe, constant |
| Bleeding: Bright red, often profuse | Bleeding: Dark red, may be concealed |
| Uterus: Soft, non-tender | Uterus: Rigid, board-like, tender |
| Fetal Status: Often normal initially | Fetal Status: Often distressed (bradycardia) |
| Priority Intervention: Bed rest, monitor, prepare for C-section | Priority Intervention: Emergency delivery (C-section) |
Anatomy, Physiology & Pharmacology Points
- Pathophysiology: Separation causes hemorrhage into the decidua basalis, forming a hematoma that further separates the placenta. This destroys the area for gas/nutrient exchange.
- Consequences: Maternal: Hemorrhage → Hypovolemia → Coagulopathy (Disseminated Intravascular Coagulation - DIC). Fetal: Hypoxia → Acidosis → Death.
- Drugs: IV fluids (Lactated Ringer's, Normal Saline) for volume. Blood products may be needed. Tocolytics (like magnesium sulfate) are contraindicated in abruption.
Memory Tips
- Abruption = "Rupture" + "Abdominal": Think of a sudden rupture causing severe abdominal pain and a rigid "board-like" abdomen.

High-Frequency NCLEX Topics
NCLEX loves testing
prioritization in obstetric emergencies. You must distinguish between urgent (needs action now) and important (needs to be done soon) interventions. The rule: If both mother and baby are in immediate danger (like here), the action that saves both (emergency delivery) is
always the top priority over supportive measures.
Watch Out for Question Variations!
- Slight Variation: "The client is at 28 weeks with a small abruption, stable vitals, and a reassuring FHR strip." The priority may shift to monitoring, bed rest, and corticosteroid administration for fetal lung maturity, not immediate delivery.
- Different Angle: The question might ask for the first action instead of the priority. "First" often implies an initial assessment or stabilizing action (e.g., apply oxygen, position, start IV), while "priority" implies the most critical action for the outcome (delivery).
