A nurse is caring for a pregnant client at 32 weeks gestation who has been diagnosed with chorioamnionitis. Which nursing intervention should be the priority?

Chorioamnionitis is a serious intrauterine infection requiring immediate delivery and antibiotics to prevent maternal sepsis and fetal complications. Other interventions like fever reduction or positioning are supportive but do not address the underlying infection.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for a patient with Chorioamnionitis, which is an infection of the fetal membranes (chorion and amnion) and amniotic fluid. It is a true obstetric emergency. The pathophysiology involves bacterial infection ascending from the vagina into the uterus, leading to inflammation. This condition poses severe risks to both mother and fetus, including Maternal sepsis, Endometritis, and for the fetus, risks of Neonatal sepsis, Pneumonia, and long-term neurological injury. The cornerstone of treatment is source control—removing the infected environment (the uterus and its contents).

Answer Rationale: Key Point! The definitive treatment for chorioamnionitis is delivery of the fetus and placenta to eliminate the source of infection, combined with broad-spectrum intravenous antibiotics. At 32 weeks gestation, the fetus is considered preterm but viable. Delaying delivery to continue the pregnancy allows the infection to worsen, increasing the risk of catastrophic maternal sepsis and poor fetal outcomes. Therefore, the nurse's priority is to prepare for delivery (which may be via induction of labor or cesarean section) and ensure timely administration of antibiotics as prescribed. This intervention directly addresses the life-threatening nature of the condition.

Distractor Analysis:

• Option 1 (Administer acetaminophen): While managing maternal fever is a supportive measure for comfort and to reduce metabolic demand, it is not the priority. Fever is a symptom of the underlying infection; treating the symptom does not treat the cause. This is a secondary intervention.
• Option 2 (Encourage fluids): Maintaining hydration is important, especially with fever, to support maternal circulation and prevent dehydration. However, like fever management, this is a supportive measure and does not address the root cause of the infection.
• Option 3 (Left lateral position): This position is a standard, beneficial intervention in pregnancy to displace the uterus off the maternal inferior vena cava, improving venous return and uteroplacental perfusion. In the context of chorioamnionitis, optimizing fetal circulation is important, but it is again a supportive measure. The imminent threat of systemic infection outweighs the benefit of positional changes alone.

Related Concepts: The principle of ABCs (Airway, Breathing, Circulation) and Maslow's Hierarchy of Needs guides priority setting. Here, the threat to physiological integrity (risk of sepsis and death) from an untreated infection takes precedence over comfort, hydration, or even optimal fetal positioning. This scenario also integrates knowledge of obstetric emergencies and the nursing process, where assessment of a critical condition leads directly to planning for definitive treatment.

Side-by-Side Comparison!

Condition	Pathophysiology	Priority Nursing Intervention
Chorioamnionitis	Bacterial infection of amniotic sac.	Prepare for delivery & administer antibiotics. (Treat infection source)
Placental Abruption	Premature separation of placenta from uterus.	Assess for hemorrhage & shock, prepare for emergency delivery. (Treat hemorrhage)
Placenta Previa	Placenta implants over cervical os.	Maintain bed rest, monitor for bleeding, avoid vaginal exams or intercourse. (Prevent hemorrhage)

Anatomy, Physiology & Pharmacology Points

• Anatomy/Physiology: The amniotic sac is normally a sterile environment. Infection breaches this barrier, triggering a maternal inflammatory response (fever, tachycardia) that can lead to systemic inflammatory response syndrome (SIRS) and sepsis.
• Pharmacology: Antibiotics used are typically broad-spectrum, covering common pathogens like Group B Streptococcus and anaerobes (e.g., ampicillin + gentamicin, or clindamycin + gentamicin). They are given IV for rapid effect.

Memory Tips

• Acronym: D.A.D. for Chorio: Deliver, Antibiotics, Don't delay!
• Think Source Control: The baby and placenta are in an infected "bath." The priority is to get them out of there and treat the infection systemically.

High-Frequency NCLEX Topics Chorioamnionitis is a classic NCLEX High Yield topic. The exam tests your ability to recognize it as an emergency and to prioritize interventions that treat the underlying cause over supportive measures. Be prepared for questions linking maternal fever + tachycardia + fetal tachycardia + uterine tenderness to this diagnosis.

Watch Out for Question Variations!

• Symptom Recognition: "A client at 35 weeks has a fever of 38.8°C (101.8°F), uterine tenderness, and fetal tachycardia. The nurse should suspect..." (Answer: Chorioamnionitis).
• Priority Assessment: "After diagnosing chorioamnionitis, which assessment finding is most critical to report immediately?" (Answer: Signs of maternal sepsis, like hypotension or altered mental status).
• Patient Education: "A client asks why she needs to deliver early. The nurse's best response is based on which rationale?" (Answer: To prevent life-threatening infection for both mother and baby).

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on the labor and delivery unit. A 32-year-old G2P1 at 32 weeks gestation is admitted with complaints of fever, chills, and generalized malaise. She reports her "water broke" 18 hours ago. On assessment: Temp 39.1°C (102.4°F), HR 120 bpm, BP 118/74. The uterus is tender to palpation. The external fetal monitor shows a fetal heart rate (FHR) baseline of 170 bpm with minimal variability. The physician diagnoses chorioamnionitis.

Nursing Intervention Strategy:

1. Immediate Actions (Priority):
   • Notify the physician/CNM (Certified Nurse-Midwife) of the confirmed diagnosis and assessment findings.
   • Initiate two large-bore IV lines for fluid resuscitation and antibiotic administration.
   • Administer the prescribed broad-spectrum IV antibiotics STAT. Ensure you understand the drug, dose, route, and potential allergic reactions.
   • Prepare the patient for delivery: This may involve starting oxytocin (Pitocin) for induction of labor or preparing for a cesarean section. Ensure the operating room is notified if a C-section is planned.
   • Continuous electronic fetal monitoring (EFM) is essential to assess for fetal distress, which is common with infection.
2. Ongoing Supportive Care:
   • Monitor maternal vital signs frequently (every 15-30 minutes initially) for signs of worsening infection or sepsis (e.g., rising HR, dropping BP, increased fever).
   • Administer antipyretics (e.g., acetaminophen) as ordered for fever and comfort.
   • Encourage oral fluids if tolerated, or manage IV fluids to maintain hydration.
   • Position the patient in left lateral tilt, especially if supine, to optimize perfusion.
   • Provide emotional support and clear explanations to the patient and family about the urgency of the situation.

Patient Safety and Precautions:

• Key Point! Time is tissue (and life). Delays in antibiotic administration or delivery increase morbidity.
• Monitor for anaphylaxis with antibiotic administration.
• After delivery, the newborn will require immediate assessment by the neonatal team and will likely be started on antibiotics. The placenta should be sent to pathology for culture.
• The mother requires close postpartum monitoring for endometritis or wound infection.

Nursing Procedure & Medication Flow Antibiotic Administration in Chorioamnionitis:

1. Verify the order: e.g., "Ampicillin 2g IV now, then 1g IV q6h AND Gentamicin 5 mg/kg IV now (based on dosing weight)."
2. Perform allergy check.
3. Obtain blood cultures before administering the first dose of antibiotics, if possible, to identify the causative organism.
4. Administer via IV piggyback (IVPB) over the prescribed time (e.g., 30 minutes for ampicillin).
5. Monitor for effectiveness (reduction in fever, improvement in vital signs) and for side effects (nephrotoxicity/ototoxicity with gentamicin).

A Word from Your Senior Nurse "In real clinical practice, chorioamnionitis is one of those diagnoses that gets everyone moving quickly. Your role as the nurse is pivotal. You're the one at the bedside recognizing the subtle signs—maybe it's a mom who just 'doesn't look right' plus a fever—and escalating care. You're the one ensuring the antibiotics are hung without delay and that the patient understands why this sudden change in plan is happening. This isn't just about passing a test; it's about having the knowledge and confidence to act decisively when two lives are on the line. Remember: infection in pregnancy is a sprint, not a marathon. Your quick, prioritized actions make all the difference."
