A 32-year-old woman at 38 weeks gestation suddenly develops severe dyspnea, hypotension, and altered mental status during labor. The fetal heart rate shows severe bradycardia. Anaphylactoid syndrome of pregnancy (ASP) is suspected. What is the nurse's priority intervention?

Immediate cesarean delivery is the priority to remove the source of amniotic fluid embolism and allow effective maternal resuscitation. Other interventions like oxygen or fluid resuscitation are important but do not address the underlying cause.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for a suspected Anaphylactoid Syndrome of Pregnancy (ASP), also known as Amniotic Fluid Embolism (AFE). This is a rare, catastrophic, and often fatal obstetric emergency. The pathophysiology involves amniotic fluid, fetal cells, or debris entering the maternal circulation, triggering a severe anaphylactoid (allergic-like) reaction and disseminated intravascular coagulation (DIC). This leads to a triad of symptoms: acute respiratory distress, cardiovascular collapse (hypotension), and coagulopathy. The scenario describes the classic presentation: sudden dyspnea, hypotension, altered mental status, and fetal distress (severe bradycardia).

Answer Rationale: Key Point! The priority is Preparing for immediate cesarean delivery while initiating cardiopulmonary resuscitation (CPR). This is a critical, life-saving intervention for two reasons. First, the fetus is in severe distress (bradycardia), indicating imminent risk of death. Second, and more importantly for maternal survival, effective chest compressions during CPR are nearly impossible with a term-sized uterus compressing the maternal aorta and inferior vena cava (aortocaval compression). Delivering the fetus relieves this compression, allowing for effective circulation of blood and medications during resuscitation. The source of the ongoing embolic and coagulopathic insult is the pregnant uterus; delivery is part of treating the cause.

Distractor Analysis: Watch out for confusion! Option ② (Administer high-flow oxygen and establish IV access) represents excellent supportive care and is part of the standard management algorithm. However, in this specific scenario of maternal cardiac arrest or near-arrest with fetal distress, it is not the priority. You cannot oxygenate or resuscitate a patient effectively with an undelivered term pregnancy.
Option ③ (Left lateral position) is a standard maneuver to relieve aortocaval compression in a stable pregnant patient. In a patient with altered mental status and hypotension who may need CPR, the priority is to prepare for delivery and place the patient supine with manual left uterine displacement for resuscitation.
Option ④ (Coagulation studies and prepare for transfusion) addresses the anticipated DIC component of ASP, which is crucial. However, this is a diagnostic and treatment step that follows the immediate life-saving interventions of securing the airway, supporting circulation, and delivering the fetus to enable that support.

Related Concepts: The management of ASP follows the principles of managing any cardiopulmonary arrest with a special obstetric consideration: "If the mother can't be resuscitated within 4 minutes, prepare for perimortem cesarean delivery to save both the mother and the fetus." This intervention serves maternal resuscitation first, fetal salvage second.
Concept Summary

Concept	Key Points
Anaphylactoid Syndrome of Pregnancy (ASP)	Catastrophic entry of amniotic fluid into maternal circulation. Presents with sudden dyspnea, hypotension, altered mental status, coagulopathy (DIC).
Priority Intervention	In cardiac arrest/near-arrest: Immediate preparation for cesarean delivery to enable effective maternal CPR and relieve aortocaval compression.
Supportive Care	High-flow O2, large-bore IVs, fluid resuscitation, vasopressors, blood products for DIC – all initiated concurrently but secondary to the delivery priority in arrest.
Fetal Consideration	Fetal bradycardia is a sign of severe maternal compromise. Saving the mother is the best chance to save the baby.

Side-by-Side Comparison!

Obstetric Emergency	Key Feature	Initial/Priority Nursing Action
Anaphylactoid Syndrome of Pregnancy (ASP)	Sudden cardiorespiratory collapse + DIC + fetal distress.	Prepare for immediate cesarean delivery to facilitate maternal resuscitation.
Uterine Rupture	Sudden tearing pain, loss of fetal station, maternal tachycardia, hypotension.	Call for help, administer O2, establish large-bore IVs, prepare for emergency laparotomy.
Placental Abruption	Painful, dark vaginal bleeding; woody, tender uterus; fetal distress.	Position left lateral, administer O2, monitor for shock and DIC, prepare for urgent delivery.
Eclampsia	Seizure in a patient with preeclampsia.	Ensure patient safety (side-lying, padded rails), administer MgSO4 (Magnesium Sulfate) as ordered, prepare for delivery.

Anatomy, Physiology & Pharmacology Points

• Pathophysiology: Amniotic fluid embolism triggers a biphasic response: 1) Pulmonary vasospasm and hypertension leading to right heart failure and hypoxia. 2) Left heart failure and cardiovascular collapse, followed by DIC due to release of thromboplastin-like material.
• Aortocaval Compression: After 20 weeks gestation, the gravid uterus compresses major vessels in the supine position, reducing venous return and cardiac output by up to 30%. This makes CPR ineffective unless relieved.
• Drugs: Management is supportive. Epinephrine is first-line for cardiac arrest. Blood products (FFP, cryoprecipitate, platelets) are critical for managing the consumptive coagulopathy of DIC.

Memory Tips

• Acronym for ASP Triad: Dyspnea, Collapse, Coagulopathy (DCC).
• Priority Rule: Think "ABCs for Mom, then D for Delivery." In maternal arrest, you must Deliver to do effective ABCs.
• Timing: Remember the "4-minute rule" for perimortem C-section: If no return of spontaneous circulation (ROSC) in 4 minutes of CPR, deliver to save the mother and possibly the fetus.

High-Frequency NCLEX Topics ASP is a high-acuity, low-frequency topic that the NCLEX loves to test because it requires prioritization and integration of knowledge (OB, med-surg, critical care). You will likely be given a scenario where you must choose between several correct actions (oxygen, IV, position, delivery) and identify the one that is most critical first. Always look for keywords: "sudden," "severe dyspnea," "hypotension," "altered mental status," "fetal bradycardia."
Watch Out for Question Variations!

• Symptom Identification: "A laboring patient develops acute respiratory distress and hypotension. The nurse suspects amniotic fluid embolism. Which finding would further support this suspicion?" (Answer: Development of coagulopathy/DIC – bleeding from IV sites, gums).
• Post-Delivery Care: "Following emergency cesarean for ASP, the patient is admitted to ICU. Which lab result is the nurse's priority to monitor?" (Answer: Fibrinogen level – it is consumed in DIC).
• Team Communication: "The nurse identifies signs of ASP. After calling for help, what is the nurse's next action?" (Answer: Initiate CPR if pulseless/apneic AND call for preparation of the OR for immediate cesarean delivery).

Nursing Clinical Practice Guide Clinical Scenario: You are the labor nurse for Gina, a 32-year-old G1P0 at 38 weeks. She has been in active labor for 6 hours with epidural analgesia. Suddenly, she sits up gasping, "I can't breathe!" You note her SpO2 is 85%, heart rate 140 bpm, BP 70/40, and she becomes confused. The external fetal monitor shows a fetal heart rate of 60 bpm (profound bradycardia).

Nursing Intervention Strategy: 1. Immediate Action (Seconds): Shout for help! Call a Code Blue and an Obstetric Emergency (e.g., "Stat cesarean to Room 5!"). If she loses consciousness and is pulseless, begin high-quality CPR. 2. Simultaneous Priorities: While calling for help, your team should: * Airway/Breathing: Apply a non-rebreather mask at 15 L/min or prepare for rapid sequence intubation by the anesthesia team. * Circulation: Establish TWO large-bore (14- or 16-gauge) IV lines. Begin a rapid isotonic crystalloid (Normal Saline or Lactated Ringer's) bolus. * Delivery: This is the core intervention. Communicate clearly to the team: "Patient is in probable AFE with arrest/near-arrest. We need to move to OR NOW for perimortem C-section." The goal is incision within 5 minutes of arrest. 3. Ongoing Management: In the OR/ICU, anticipate and manage DIC: massive transfusion protocol (MTP) with packed red blood cells (PRBCs), fresh frozen plasma (FFP), platelets, and cryoprecipitate.

Patient Safety and Precautions: * Do not delay CPR for transport. Initiate CPR immediately at the bedside. Manual left uterine displacement (pushing the uterus to the left) must be performed during compressions to relieve aortocaval compression until delivery. * Communication is critical. Use closed-loop communication. Designate roles: one nurse for meds/IVs, one for documentation/time-keeping, one for communicating with family. * Know your facility's OB emergency protocols. Many have specific "AFE/Maternal Arrest" packs or carts.
Nursing Procedure & Medication Flow During Maternal Code with Perimortem C-Section: 1. CPR: Compressions at 100-120/min. Allow full chest recoil. Switch compressors every 2 minutes. 2. Defibrillation: If a shockable rhythm (VF/VT) is identified, defibrillate at standard energy levels. It is safe for the fetus. 3. Medications: Administer code medications (Epinephrine 1mg IV q3-5min) per ACLS protocol. There is no change in dosing for pregnancy. 4. Delivery: The obstetrician will perform the fastest possible cesarean delivery. The nurse assists by ensuring the surgical team has immediate access, continuing CPR until the moment of incision, and preparing neonatal resuscitation for the baby. 5. Post-Delivery: Continue full ACLS. Now, CPR may become more effective. Aggressively treat coagulopathy with blood products as they arrive.
A Word from Your Senior Nurse This is one of the most terrifying scenarios in obstetrics. Remember, your knowledge and swift, prioritized actions can mean the difference between life and death for two people. In a crisis, fall back on your fundamentals: Airway, Breathing, Circulation – but in the pregnant patient, you must immediately add D for Delivery to that sequence when there is arrest. Don't panic. Your role is to recognize, call for the right help, start life-supporting measures, and be the organized point person for your team. Studying these high-stakes scenarios builds the mental muscle memory you need to act decisively in real life. You've got this!
