A nurse is caring for a 1-day-old newborn born at 37 weeks gestation who exhibits signs of respiratory distress. The infant has a respiratory rate of 70 breaths per minute, nasal flaring, and mild intercostal retractions. Which nursing intervention should the nurse implement first?

Positioning in a neutral thermal environment and assessing oxygen saturation are the first steps to evaluate respiratory distress severity before implementing interventions like oxygen or notification. Other options may be needed based on assessment findings.

Understanding the Clinical Presentation

The newborn in this scenario is exhibiting classic signs of respiratory distress, including tachypnea with a respiratory rate of 70 breaths per minute, nasal flaring, and intercostal retractions. These findings indicate increased work of breathing as the infant attempts to maintain adequate gas exchange. At 1 day of age, this presentation can stem from several transitional or pathological causes, such as transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), or infection. The immediate priority is not to apply a specific treatment blindly but to conduct a focused, non-invasive assessment to determine the severity of hypoxemia, which will guide the urgency and type of the next intervention.

Prioritizing Nursing Interventions

The question asks for the first nursing intervention. Using a clinical reasoning framework, assessment must precede and guide all other actions. Before notifying a physician or initiating a therapy like oxygen, the nurse must gather critical, objective data at the bedside.

- Option 1 (Administer supplemental oxygen): While the infant is in distress, administering oxygen without first knowing the oxygen saturation (SpO₂) is premature and potentially harmful. The 2025 neonatal resuscitation guidelines emphasize a targeted approach to oxygen therapy to avoid the risks of both hypoxia and hyperoxia ^[2]. Hyperoxia can lead to oxidative stress and tissue injury. Therefore, oxygen titration must be guided by pulse oximetry readings.
- Option 2 (Notify the pediatrician): Communication with the physician is essential, but it is most effective when the nurse can provide a complete clinical picture using a structured assessment tool. A study on the PSU-neonatal early warning score (PSU-NEWS) highlights that such scores are designed to help nurses rapidly assess a neonate's status and then communicate clinical concerns with objective data, facilitating a more efficient and accurate response ^[1]. Calling the physician before having a full set of vital signs, including SpO₂, would delay the gathering of information that is critical for medical decision-making.
- Option 4 (Prepare for intubation): Preparing for invasive ventilation is a high-acuity intervention that is not the first-line response for an infant with mild-to-moderate retractions who is breathing spontaneously. The initial steps of neonatal stabilization always begin with less invasive measures, including positioning, clearing the airway, and providing continuous positive airway pressure (CPAP) or oxygen if needed, guided by assessment ^[2].

Why Option 3 is the First Priority

Placing the infant in a neutral thermal environment and assessing oxygen saturation is the correct first step because it combines a fundamental supportive measure with a critical assessment. A neutral thermal environment minimizes oxygen consumption due to cold stress, which can worsen respiratory distress. Simultaneously, applying a pulse oximeter to obtain a pre-ductal SpO₂ reading provides immediate, objective data on the infant's oxygenation status. Research on clinical monitoring in the NICU demonstrates that when physicians evaluate a multiparameter monitor, their visual attention is primarily captured by SpO₂ and heart rate to determine the presence of vital sign alterations . This confirms that oxygen saturation is a pivotal data point in the rapid assessment of a neonate's clinical trajectory. By first obtaining this value, the nurse can then accurately report the complete clinical picture, including the degree of hypoxemia, to the pediatrician and safely initiate or withhold oxygen therapy based on evidence-based target saturation ranges.
