A nurse is caring for a 1-week-old newborn with suspected sepsis. The infant's vital signs are: temperature 97.2°F (36.2°C), heart rate 180 bpm, respiratory rate 68/min, and blood pressure 55/30 mmHg. Which nursing intervention should be the priority?
The newborn appears lethargic, has poor feeding tolerance, and exhibits mottled skin. Laboratory results show elevated white blood cell count and elevated C-reactive protein.

해설
Establishing vascular access for fluid resuscitation is the priority to address hypotension and shock in neonatal sepsis, ensuring adequate circulation before administering antibiotics. Other interventions are important but secondary to hemodynamic stabilization.
Clinical Judgment
This question assesses Prioritization and Clinical Judgment in a newborn showing signs of septic shock. The core principle is to address life-threatening conditions first. The infant presents with hypothermia, tachycardia, tachypnea, and hypotension, along with clear clinical signs of shock such as lethargy, poor feeding, and mottled skin. This is a Notify HCP! situation, indicating that sepsis has progressed to hemodynamic instability (septic shock). In this case, the most immediate threat is circulatory failure. Securing vascular access is the foundation for all subsequent treatments—including fluid resuscitation, medication administration, and blood sample collection—making it the first life-saving step.
Memory Tip
Remember the ABC (Airway, Breathing, Circulation) principle. For this infant, Circulation is the most threatened. The mnemonic "If there's shock, grab a Vein first" can also be helpful.
KR vs US
While fluid resuscitation and securing vascular access are also important in septic shock in Korea, the NGN/US exams apply the prioritization principle of "addressing the most life-threatening problem first" very strictly. Administering antibiotics is essential for treating the infection, but its effectiveness may be limited if hemodynamic stabilization is not achieved first.
Clinical Practice Guide
The first step in managing neonatal septic shock is rapid vascular access. This allows you to start bolus infusions of isotonic fluids (e.g., Normal Saline) to improve blood pressure and perfusion. At the same time, after collecting blood culture specimens, antibiotics should be administered as soon as possible (typically within 1 hour of securing vascular access). Continuous monitoring of vital signs, peripheral perfusion (capillary refill time), oxygen saturation, and urine output is essential.
Caution
In SATA (Select All That Apply) questions, if asked about "interventions needed for a septic neonate," both "antibiotic administration" and "fluid resuscitation" can be correct answers. However, if the question asks for the "highest priority intervention" as in this case, circulatory support (vascular access/fluids) always takes precedence when hemodynamic instability is present.
Neonatal Sepsis — Systemic bacterial infection occurring in newborns within 28 days of birth. It is classified into early-onset (within 7 days of birth) and late-onset based on the time of onset, and presents with nonspecific symptoms (lethargy, poor feeding, respiratory distress, etc.).
Septic Shock — Distributive shock due to sepsis. A systemic inflammatory response to infection causes vasodilation, capillary leakage, and abnormal blood distribution, leading to hypotension and organ hypoperfusion.
Mottled Skin — Mottled skin. A phenomenon where irregular white and red or blue patches appear on the skin, indicating peripheral vasomotor instability or poor perfusion, and an important sign of neonatal sepsis or shock.
Fluid Resuscitation — Emergency treatment that rapidly replenishes intravascular volume to restore blood pressure and tissue perfusion. In septic shock, bolus infusion of isotonic crystalloid solutions (e.g., normal saline) is the first step.
C-reactive Protein — C-reactive protein. An acute-phase reactant produced in the liver, its blood concentration rises sharply during infection or inflammation, and it is used for diagnosis and monitoring treatment response.
