A nurse is caring for a 35-week late preterm infant with mild respiratory distress. Which nursing intervention should be the highest priority?

Surfactant replacement therapy is the priority for RDS as it directly addresses surfactant deficiency. Other interventions are supportive but not immediate priorities: antibiotics don't treat RDS, prone positioning helps but doesn't correct the underlying cause, and phototherapy is for hyperbilirubinemia.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a late preterm infant (35 weeks) presenting with respiratory distress. The core theme is recognizing the likely underlying cause—Respiratory Distress Syndrome (RDS)—and understanding the definitive, life-saving treatment. RDS is primarily caused by a deficiency of pulmonary surfactant, a substance produced by type II alveolar cells that reduces surface tension in the lungs, preventing alveolar collapse at the end of expiration. Late preterm infants (34-36 weeks) are at significant risk for surfactant deficiency as their lungs are still maturing.

Answer Rationale: Key Point! The highest priority intervention is to prepare for surfactant replacement therapy administration. This directly addresses the primary pathophysiological problem of surfactant deficiency. Administering exogenous surfactant improves lung compliance, reduces the work of breathing, and decreases the need for high levels of oxygen and mechanical ventilation. It is a critical, time-sensitive intervention to prevent further respiratory deterioration and complications like bronchopulmonary dysplasia (BPD).

Distractor Analysis:
Watch out for confusion! Option ① (Administer prophylactic antibiotics) is incorrect because it addresses a potential complication (infection) rather than the immediate, life-threatening cause of the distress. While sepsis can mimic RDS, the scenario specifies "mild respiratory distress" in a late preterm infant, making RDS the most probable primary diagnosis. Antibiotics are not a treatment for surfactant deficiency.
Option ② (Position the infant in prone position) is a supportive measure. While the prone position can improve oxygenation by optimizing ventilation-perfusion matching and reducing the work of breathing, it is a non-invasive, supportive intervention that does not correct the underlying surfactant deficiency. It would be implemented, but it is not the definitive, highest-priority treatment.
Option ④ (Initiate phototherapy) is incorrect because it addresses a common comorbidity in preterm infants—hyperbilirubinemia—but is unrelated to the primary problem of respiratory distress. Jaundice and respiratory distress are managed concurrently but independently; phototherapy is not an intervention for improving respiratory status.

Related Concepts: The nursing process guides us to prioritize interventions that address the most immediate threat to life (Airway, Breathing, Circulation - ABCs). In this case, surfactant therapy directly supports "Breathing." Understanding the pathophysiology of RDS is essential for predicting clinical signs (tachypnea, grunting, retractions, nasal flaring) and anticipating the necessary medical and nursing interventions. Concept Summary

Concept	Key Takeaway
Respiratory Distress Syndrome (RDS)	Surfactant deficiency leads to alveolar collapse, poor lung compliance, and respiratory distress in preterm infants.
Surfactant Replacement Therapy	Definitive, high-priority treatment for RDS. Administered via endotracheal tube, often requiring careful positioning and monitoring.
Late Preterm Infant (34-36 weeks)	High risk for RDS, temperature instability, feeding difficulties, and hyperbilirubinemia.
Nursing Priority (ABCs)	Airway and Breathing are top priorities. Interventions that directly support these systems take precedence.

Side-by-Side Comparison!

Intervention	Purpose / Indication	Priority in RDS
Surfactant Therapy	Replace deficient pulmonary surfactant to improve lung compliance.	HIGHEST - Corrects the root cause.
Prone Positioning	Supportive care to improve oxygenation and reduce work of breathing.	Supportive - Helps manage symptoms.
Prophylactic Antibiotics	Prevent or treat bacterial infection (e.g., sepsis, pneumonia).	Secondary - Used if infection is suspected or proven.
Phototherapy	Treat hyperbilirubinemia by breaking down bilirubin in the skin.	Concurrent Care - Addresses a common comorbidity, not the respiratory issue.

Anatomy, Physiology & Pharmacology Points

• Physiology: Surfactant is produced by type II pneumocytes. Production significantly increases after about 35 weeks gestation. A deficiency increases alveolar surface tension, leading to atelectasis (collapse), decreased lung compliance, ventilation-perfusion mismatch, and hypoxemia.
• Pharmacology: Exogenous surfactants (e.g., beractant, poractant alfa) are derived from animal lungs. Administration is an intratracheal instillation. Nursing responsibilities include ensuring correct dosing, preparing for potential airway obstruction during administration, and monitoring for rapid improvements in oxygenation and compliance.

Memory Tips

• Mnemonic for RDS Signs: "Grunting, Retractions, Apnea (or flaring), Cyanosis, Tachypnea" → GRACT.
• Think: "No SURFactant, can't catch a breath wave." The priority is to give the SURF (surfactant).
• Rule of 35: Infants born before ~35 weeks are at high risk for surfactant deficiency. The question's "35-week" infant is right on the cusp.

High-Frequency NCLEX Topics NCLEX frequently tests priority-setting for neonatal emergencies. RDS and its management are core topics. Remember: Treat the cause, not just the symptoms. In neonatal respiratory distress, always consider surfactant deficiency first for preterm infants, and be ready to assist with or prepare for its administration as a top-priority action. Watch Out for Question Variations!

• Symptom Identification: "The nurse assesses a 33-week preterm infant. Which finding is most suggestive of RDS?" (Look for grunting, retractions).
• Post-Surfactant Care: "Following surfactant administration, which action is most important?" (Monitor for acute airway obstruction and assess oxygenation/ventilation).
• Prevention Focus: "The nurse is teaching a client at risk for preterm labor. Which intervention is most effective in preventing RDS?" (Administration of antenatal corticosteroids to the mother to accelerate fetal lung maturity).

Nursing Clinical Practice Guide Clinical Scenario: You are in the Neonatal Intensive Care Unit (NICU). A newborn, Baby Boy Lee, born at 35 weeks gestation via spontaneous vaginal delivery, is admitted to your care. He is tachypneic (respiratory rate 70/min), with audible expiratory grunting and mild subcostal retractions. His oxygen saturation is 88% on room air.

Nursing Intervention Strategy:

1. Assessment & Notification: Perform a rapid but thorough respiratory assessment (rate, effort, breath sounds, color, SpO2). Immediately notify the neonatal provider (neonatologist or NNNP) of the infant's respiratory status. Anticipate orders for arterial blood gas (ABG) and a chest X-ray.
2. Immediate Supportive Care: While preparing for definitive treatment, provide supportive care:
   • Apply pulse oximeter for continuous SpO2 monitoring.
   • Initiate supplemental oxygen via nasal cannula or hood as ordered to maintain SpO2 >90%.
   • Position the infant in a prone or side-lying position with proper neck alignment to optimize lung expansion.
   • Minimize handling and environmental stressors to reduce oxygen consumption.
3. Preparing for Priority Intervention: The provider diagnoses RDS and orders surfactant replacement therapy. Your role:
   • Gather equipment: Surfactant vial (warmed per protocol), sterile syringes, endotracheal tube (ETT) supplies (if not already intubated), suction equipment.
   • Assist the provider during the intratracheal instillation. This may involve turning the infant's head and torso to different positions to distribute the medication throughout the lungs.
   • Monitor vigilantly for complications during administration: bradycardia, desaturation, or ETT obstruction.
4. Post-Administration Care & Monitoring:
   • Expect rapid improvements in oxygenation and compliance. Be prepared to wean oxygen and ventilator settings quickly to avoid hyperoxia.
   • Frequent assessment of vital signs, breath sounds, and work of breathing.
   • Continue comprehensive care: maintain thermoneutral environment, initiate trophic feeds as tolerated, monitor for jaundice (hyperbilirubinemia).

Patient Safety and Precautions:

• Surfactant Administration: Ensure the ETT is correctly positioned before and after administration. Have suction ready. Do not suction the ETT for 1-2 hours after administration unless absolutely necessary to avoid removing the medication.
• Infection Control: Maintain strict aseptic technique during all procedures, especially those involving the airway.
• Thermoregulation: Use a radiant warmer or incubator to prevent cold stress, which increases metabolic demand and oxygen consumption.

Nursing Procedure & Medication Flow Assisting with Surfactant Administration (General Steps): 1. Verification: Verify order, patient identity, and medication. Warm the surfactant vial as per manufacturer instructions (usually to room temperature). 2. Preparation: Draw up the exact dose into a syringe without air bubbles. Ensure the ETT is patent and secure. 3. Positioning & Administration: Assist the provider who will instill the medication in divided doses (e.g., quarter turns). The infant is typically repositioned (left side, right side, head up, head down) after each aliquot to promote distribution. 4. Monitoring: Continuously monitor heart rate, oxygen saturation, and color during the procedure. Provide manual ventilation with 100% oxygen as needed. 5. Post-Procedure: Secure the ETT. Document the procedure, dose, lot number, and the infant's response. A Word from Your Senior Nurse "In the NICU, every second counts for a struggling newborn.
