A nurse is caring for a laboring client at 40 weeks gestation who has been diagnosed with chorioamnionitis. The client's temperature is 101.2°F (38.4°C), heart rate is 110 bpm, and fetal heart rate shows baseline tachycardia at 170 bpm. Which nursing intervention should be the priority?

For chorioamnionitis during labor, immediate IV antibiotics are priority to treat infection and prevent maternal/fetal sepsis. Other options like cesarean preparation or fever management are secondary until antibiotics are administered.
Understanding Chorioamnionitis and the Clinical Picture
The scenario describes a client at term with chorioamnionitis, presenting with maternal fever (101.2°F / 38.4°C), maternal tachycardia (110 bpm), and fetal tachycardia (170 bpm). Chorioamnionitis, an infection of the amniotic membranes and fluid, triggers a systemic inflammatory response. This intrauterine inflammation and the associated maternal fever directly irritate the fetal myocardium and increase the fetal metabolic rate, leading to the baseline fetal tachycardia observed here. The diagnosis signifies that the infectious process is already established and poses significant risks to both the mother and the fetus, including neonatal sepsis, pneumonia, and maternal sepsis if not treated promptly [1,3].
Prioritizing Interventions: The "Why" Behind the Answer
The priority nursing intervention is to administer prescribed intravenous antibiotics immediately. The core pathophysiological problem is an active bacterial infection. The critical need for rapid management to mitigate serious maternal-newborn risks makes the prompt initiation of antibiotic therapy the cornerstone of treatment [2]. This is not merely a task to be completed; it is a time-sensitive intervention that directly targets the source of the clinical instability. Delaying antibiotic administration allows the infection to progress, increasing the risk of severe histological chorioamnionitis, which is independently associated with adverse neonatal outcomes, including NICU admission . Coordinated interprofessional collaboration is essential to ensure this prompt administration, as it directly impacts clinical outcomes [2].
Analyzing the Alternative Options
While the other options may be components of care, they are not the immediate priority.
- Prepare the client for immediate cesarean delivery: Delivery is the definitive cure, as it removes the infected tissue (placenta and membranes). However, the priority is to first establish adequate antibiotic coverage to reduce maternal bacteremia and prevent seeding of the surgical wound, thereby lowering the risk for postpartum endometritis and wound infection. Unless there are urgent fetal indications (e.g., profound, unremitting late decelerations), antibiotic therapy precedes surgical delivery. A diagnosis of chorioamnionitis alone, in the presence of a reassuring fetal status aside from tachycardia, does not mandate an immediate, emergent cesarean section.
- Increase the rate of intravenous fluid infusion: While the client is tachycardic and may have insensible fluid losses from fever, a fluid bolus is a supportive measure. It treats a symptom (tachycardia potentially related to hypovolemia) but does not address the underlying cause—the infection. The primary driver of the tachycardia is the systemic inflammatory response to infection, which will only resolve with source control via antibiotics and eventual delivery.
- Apply cool compresses to reduce maternal fever: This is a comfort measure that provides symptomatic relief for maternal fever but has no impact on the intra-amniotic infection. Reducing maternal surface temperature does not treat the fetal bacteremia or the inflamed environment the fetus is in. The fetal tachycardia is driven by the infectious and inflammatory milieu, not solely by the maternal temperature, making antipyretics and cooling measures secondary to treating the infection itself .
The foundational principle in managing chorioamnionitis is that antibiotic therapy is the immediate, evidence-based intervention to halt the progression of the disease and prevent severe maternal and neonatal complications [1,2,3].

Clinical Management of Intrapartum Chorioamnionitis
Diagnostic Criteria
Suspect chorioamnionitis when a laboring patient presents with maternal fever (≥100.4°F or 38.0°C) plus at least one of the following: maternal tachycardia (>100 bpm), fetal tachycardia (>160 bpm), purulent amniotic fluid, or uterine tenderness. The diagnosis is clinical; do not delay treatment awaiting culture results.
Immediate Nursing Priorities
Administer IV Antibiotics: Initiate broad-spectrum antibiotics (typically Ampicillin and Gentamicin) as soon as prescribed. This is the definitive treatment to reduce maternal and neonatal sepsis risk.
Continuous Fetal Monitoring: Assess fetal heart rate patterns for tachycardia, minimal variability, or late decelerations, which may indicate worsening fetal status.
Maternal Vital Signs: Monitor temperature, heart rate, and blood pressure every 1-2 hours to track response to therapy and detect early signs of sepsis.
Supportive Care and Delivery Planning
While antibiotics are the priority, supportive measures include antipyretics (e.g., Acetaminophen) for maternal comfort and to reduce fetal metabolic demand. Cesarean delivery is reserved for standard obstetric indications, not solely for chorioamnionitis. Notify the neonatal team of the diagnosis to prepare for potential neonatal resuscitation and sepsis evaluation.
Chorioamnionitis — An acute inflammation of the amniotic membranes and fluid, typically caused by an ascending bacterial infection, presenting with maternal fever, tachycardia, and fetal tachycardia.
Fetal Tachycardia — A baseline fetal heart rate greater than 160 bpm, often caused by maternal fever, infection, or fetal hypoxia, reflecting increased metabolic demand or direct myocardial irritation.
Priority Intervention — The most critical nursing action based on the ABCs or Maslow's hierarchy, which in infection cases targets the source to prevent systemic progression and sepsis.
