A nurse is caring for a laboring client at 36 weeks gestation who has been diagnosed with chorioamnionitis. The client's temperature is 101.2°F (38.4°C), pulse is 110 bpm, and fetal heart rate shows moderate tachycardia at 170 bpm. Which nursing intervention should be the priority?

Immediate IV antibiotics are the priority to prevent maternal and fetal sepsis in chorioamnionitis. Other interventions are supportive but secondary to infection control.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a patient with Chorioamnionitis (intra-amniotic infection). This is a serious obstetric infection of the fetal membranes and amniotic fluid, most commonly caused by ascending bacteria from the vagina. The pathophysiological mechanism involves infection leading to maternal systemic inflammatory response (fever, tachycardia) and fetal stress (tachycardia). The greatest risks are progression to maternal Sepsis and neonatal sepsis, which can be life-threatening for both.

Answer Rationale: Key Point! The cornerstone of management for chorioamnionitis is prompt administration of broad-spectrum intravenous (IV) antibiotics. This intervention directly targets the underlying cause—the infection. Delaying antibiotics increases the risk of bacteremia, septic shock, and poor neonatal outcomes. The scenario presents clear signs of infection (maternal fever, tachycardia, fetal tachycardia), making antibiotic administration the immediate, life-preserving priority.

Distractor Analysis: Watch out for confusion! Option ① (position changes) is a comfort measure and part of general labor care but does not address the acute, systemic threat of infection.
Option ③ (cool compresses) is a supportive, symptomatic treatment for fever. While it may provide comfort and help lower body temperature, it is a non-priority intervention compared to treating the infection's source.
Option ④ (increase oral fluids) is important for hydration, especially with fever, but is again a supportive measure. In the context of active labor and potential for emergency delivery, IV fluids are typically administered, making oral intake a secondary concern.

Related Concepts: The priority follows the ABC (Airway, Breathing, Circulation) and "Treat the Cause" principles. While the patient's airway and breathing are not compromised, the infection is a direct threat to maternal circulation (risk of septic shock) and fetal well-being. Therefore, treating the cause (infection) with antibiotics takes precedence over comfort or symptomatic measures.

Concept Summary

Concept	Key Points
Chorioamnionitis	Infection of amniotic sac & fluid. Risks: maternal/neonatal sepsis, preterm labor, cerebral palsy.
Clinical Signs (Maternal)	Fever >100.4°F (38°C), maternal tachycardia, uterine tenderness, foul-smelling amniotic fluid.
Clinical Signs (Fetal)	Fetal tachycardia (>160 bpm) is the most common sign.
Priority Intervention	Immediate IV antibiotic administration (e.g., ampicillin + gentamicin).
Definitive Treatment	Delivery of the fetus and placenta (source removal). Antibiotics are given before and after delivery.

Side-by-Side Comparison!

Condition	Primary Concern / Pathophysiology	Priority Nursing Intervention
Chorioamnionitis	Systemic infection leading to sepsis.	Administer IV antibiotics immediately to treat infection.
Preeclampsia with severe features	Vasospasm, hypertension, risk of seizure (eclampsia).	Administer magnesium sulfate to prevent seizures.
Prolapsed umbilical cord	Cord compression causing fetal hypoxia.	Relieve pressure on cord (e.g., knee-chest position, manual elevation of presenting part).

Anatomy, Physiology & Pharmacology Points

• Pathophysiology: Bacteria ascend from the vagina through the cervix, breaching the amniotic membranes. The inflammatory response releases prostaglandins, which can stimulate uterine contractions, potentially leading to preterm labor.
• Fetal Physiology: Fetal tachycardia is a compensatory response to stress, often due to the fetal inflammatory response syndrome (FIRS) or early hypoxia from placental inflammation.
• Pharmacology: Common antibiotic regimens include ampicillin (covers Gram-positive and some Gram-negative) plus gentamicin (covers Gram-negative). Clindamycin may be added for anaerobic coverage, especially after C-section.

Memory Tips

• Acronym: A.F.F.I.R.M.
  Antibiotics First For Intra-amniotic infection Management.
• Rule of "T's" for Priority: Think "Treat the cause" before "Treat the symptom." Antibiotics treat the cause (infection), cool compresses treat a symptom (fever).
• Fetal Heart Rate (FHR) clue: Sustained fetal tachycardia in the presence of maternal fever is a classic red flag for chorioamnionitis.

High-Frequency NCLEX Topics Chorioamnionitis is a Core topic in maternal-newborn nursing. The NCLEX-RN loves to test:

1. Priority Setting: Recognizing that antibiotic administration is the #1 action.
2. Assessment Findings: Knowing the triad of maternal fever, maternal tachycardia, and fetal tachycardia.
3. Postpartum Implications: Understanding that antibiotics must continue after delivery until the mother is afebrile for 24-48 hours.

Watch Out for Question Variations!

• Shift from Intervention to Assessment: "The nurse suspects chorioamnionitis. Which finding should the nurse report immediately?" (Answer: Fetal tachycardia with maternal fever).
• Shift to Postpartum Care: "A client delivered 12 hours ago following a diagnosis of chorioamnionitis. Which finding requires immediate intervention?" (Answer: Temperature spike to 101.8°F / 38.8°C, indicating possible ongoing infection).
• Shift to Medication Administration: "The nurse is to administer gentamicin IV for chorioamnionitis. Which action is most important?" (Answer: Monitoring peak and trough levels to prevent nephrotoxicity/ototoxicity).

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on the labor and delivery unit. Your patient, a 36-week gravida, has ruptured membranes for 18 hours. She now has a temperature of 38.6°C, appears flushed and uncomfortable, and her monitor shows a fetal heart rate consistently at 165-172 bpm. The physician diagnoses chorioamnionitis and orders "Ampicillin 2g IV now, then Gentamicin 5mg/kg IV now."

Nursing Intervention Strategy:

1. Immediate Action (Priority): Acknowledge the order and prepare and administer the IV antibiotics without delay. Verify the patient's allergies first (especially to penicillin for ampicillin).
2. Concurrent Supportive Care:
   • Assessment: Continue frequent monitoring of maternal vital signs (every 30-60 minutes initially) and continuous electronic fetal monitoring (EFM). Document the characteristics of any amniotic fluid (odor, color).
   • Comfort & Safety: Provide cool washcloths to the forehead, encourage position changes for comfort, and administer acetaminophen as ordered for fever. Remember, these are done alongside, not instead of, antibiotics.
   • Hydration: Maintain IV access and administer IV fluids as ordered to support circulation and prevent dehydration from fever.
3. Communication & Preparation: Inform the obstetric team of the patient's status. Prepare for the likelihood of expedited delivery (vaginal or cesarean) once antibiotics have been initiated. Educate the patient and family about the diagnosis and plan in simple terms.

Patient Safety and Precautions:

• Antibiotic Precautions: Gentamicin is nephrotoxic and ototoxic. Ensure dosing is based on current weight. Monitor urine output and be aware that peak/trough levels will be drawn.
• Neonatal Precautions: Notify the neonatal resuscitation team (NRT) prior to delivery. The newborn will require close observation and likely blood cultures and empiric antibiotics after birth.
• Infection Control: Practice strict hand hygiene and standard precautions. While chorioamnionitis is not typically "contagious" in the airborne sense, it underscores the importance of aseptic technique during vaginal exams and procedures.

Nursing Procedure & Medication Flow Procedure: Administering IV Antibiotics for Chorioamnionitis

1. Verify: Physician's order, patient identity (two identifiers), and allergy status.
2. Prepare: Obtain antibiotics from pharmacy/pyxis. Ampicillin often requires reconstitution. Check expiration dates.
3. Administer:
   • Use a patent IV line. If one is not present, establish IV access promptly.
   • Administer ampicillin first (often over 30 minutes), followed by gentamicin (often over 30-60 minutes).
   • Do not mix antibiotics in the same IV bag or syringe unless specifically compatible.
4. Monitor: Observe for signs of anaphylaxis during and after infusion (rash, wheezing, hypotension). Monitor for Red Man Syndrome with vancomycin if it is part of the regimen (flushing, rash, hypotension).
5. Document: Drug, dose, route, time, site, and patient response (e.g., "IV antibiotics initiated, patient tolerating well").

A Word from Your Senior Nurse "In the fast-paced world of L&D, chorioamnionitis is one of those 'time is tissue' situations—but here, time is two lives. Your quick action in getting those antibiotics on board is the single most important thing you can do as the nurse. It's easy to get distracted by the fever, the fetal heart rate tracing, and the patient's discomfort. Your brain must automatically sort those into 'treat cause' vs. 'manage symptoms.' Remember this: delaying antibiotics by even an hour can change the outcome for that baby. So when you see that classic triad—mom with a fever, mom's heart racing, baby's heart racing—your internal alarm should scream 'INFECTION, NEED ANTIBIOTICS NOW.' That clinical judgment, backed by solid knowledge, is what makes an excellent nurse."
