A 5-day-old newborn in the NICU is suspected of having sepsis. The nurse notes the infant has a temperature of 96.8°F (36°C), abdominal distension, and weak cry. Which nursing action should be the HIGHEST priority?

Respiratory assessment and support is the highest priority as sepsis can rapidly progress to life-threatening respiratory failure in newborns. Other actions like antibiotics, blood cultures, or warming are secondary.

Core Nursing Explanation This question tests the critical nursing skill of prioritization in a neonatal emergency, specifically for a newborn with suspected sepsis. The core principle is the ABCs (Airway, Breathing, Circulation), which always take precedence over diagnostic or treatment interventions. Key Concept Analysis The scenario describes a 5-day-old in the NICU with signs of neonatal sepsis: hypothermia (96.8°F/36°C), abdominal distension, and a weak cry. A weak cry is a significant red flag, as it can indicate respiratory distress, fatigue, or neurological depression—all potential consequences of systemic infection. In neonates, sepsis can cause rapid deterioration, leading to apnea, respiratory failure, and septic shock. Therefore, the nurse's first action must be to ensure the infant's physiological stability, starting with the airway and breathing. Answer Rationale Key Point! Option ④, "Assess and support respiratory status," is the highest priority. The weak cry is a non-specific but highly concerning sign that demands immediate respiratory assessment. Before administering antibiotics (which treat the cause) or obtaining cultures (which diagnose it), the nurse must ensure the baby is breathing effectively. Supporting the airway and breathing is a fundamental, life-preserving intervention that aligns with the ABC priority framework. Distractor Analysis Watch out for confusion! While all the actions are important and will be performed, they are not the *first* priority.
① Administer prescribed antibiotics immediately: Antibiotics are crucial for treating sepsis, but administration is not the *first* action. The nurse must first ensure the patient is stable enough to receive them. A patient in respiratory arrest cannot benefit from antibiotics.
② Obtain blood cultures before any interventions: Cultures are essential for diagnosis and guiding antibiotic therapy. However, the standard of care is to obtain cultures *before* administering the first dose of antibiotics to avoid false-negative results. While this is a key step, it is still secondary to ensuring physiological stability (ABCs).
③ Place the infant under a radiant warmer: Correcting hypothermia is important for metabolic stability and is part of supportive care. However, a weak cry indicates a potentially more immediate threat to life (inadequate breathing) than a slightly low temperature. Related Concepts Neonatal sepsis is a medical emergency. Signs are often subtle and non-specific (e.g., temperature instability, feeding intolerance, lethargy, weak cry). The nursing approach always follows: Stabilize (ABCs) → Diagnose (labs/cultures) → Treat (antibiotics, supportive care). Remember, you cannot treat a patient who is not breathing.

Nursing Clinical Practice Guide Clinical Scenario You are the NICU nurse for Baby Girl Rodriguez, born at 38 weeks, now day 5 of life. She was feeding well but today is lethargic, has a weak cry when stimulated, feels cool to thetouch, and her abdomen appears slightly distended and firm. Your initial rapid assessment reveals heart rate 180 bpm, respiratory rate 70 with mild subcostal retractions, and SpO2 92% on room air. Nursing Intervention Strategy 1. Immediate Assessment & Support (ABCs): Your first action is to assess the airway and breathing. You would stimulate the infant, ensure the airway is patent, and apply supplemental oxygen via nasal cannula or hood to maintain SpO2 >95%. You would prepare bag-valve-mask ventilation at the bedside. Simultaneously, you call for help and alert the neonatal provider. 2. Diagnostic Actions: Once breathing is supported, you would obtain blood cultures (and possibly a lumbar puncture per protocol) *before* administering the first dose of antibiotics. You would also draw labs (CBC with differential, CRP). 3. Treatment & Supportive Care: After cultures are drawn, you administer the first dose of IV antibiotics (e.g., ampicillin and gentamicin) promptly. You place the infant under a radiant warmer with a servo-control probe to correct hypothermia. You would hold feeds due to abdominal distension (risk for necrotizing enterocolitis) and initiate IV fluids. 4. Ongoing Monitoring: Continuous cardiorespiratory monitoring, frequent vital signs, strict I&O, and assessment for signs of shock (capillary refill >3 seconds, mottling, hypotension). Patient Safety and Precautions - Key Point! Never delay respiratory support for any other procedure. - Strict aseptic technique is mandatory for all invasive procedures (blood draws, IV access) in an immunocompromised septic infant. - Know the signs of respiratory failure in neonates: apnea, severe retractions, grunting, cyanosis. Nursing Procedure & Medication Flow Sequence for Suspected Neonatal Sepsis: 1. Assess & support ABCs (Airway, Breathing, Circulation). 2. Call for help/rapid response. 3. Obtain blood cultures (and other cultures as ordered) using sterile technique. 4. Administer first dose of IV antibiotics STAT (ensure correct weight-based dosing). 5. Initiate thermoregulation (radiant warmer). 6. Establish IV access if not present, begin IV fluids. 7. Implement continuous monitoring and frequent reassessments. A Word from Your Senior Nurse "In the NICU, we say 'a quiet baby is a sick baby.' That weak cry is your patient's only way of telling you they're in trouble—listen to it! In high-stakes situations like sepsis, your brain might scream 'get the antibiotics!' but your hands need to follow the ABCs first. Mastering this prioritization isn't just for the NCLEX; it's the muscle memory that saves lives. Always ask yourself: 'What will kill my patient first?' The answer is almost always a problem with the ABCs."
