## 문제

A 3-day-old newborn in the NICU is suspected of having sepsis. The infant's temperature is 96.8°F (36.0°C), heart rate is 170 bpm, and respiratory rate is 65 breaths per minute. Blood cultures have been obtained. What is the most appropriate immediate nursing intervention?

## 보기

1. Wait for blood culture results before implementing any interventions
2. Initiate broad-spectrum antibiotic therapy as prescribed **✔ 정답**
3. Increase the ambient temperature in the isolette to normalize body temperature
4. Restrict fluid intake to prevent fluid overload

**정답: 2**

## 해설

Initiating broad-spectrum antibiotic therapy is the most appropriate immediate intervention for suspected neonatal sepsis to prevent rapid deterioration, as waiting for culture results or other measures delays critical treatment.

Clinical Presentation and Initial Recognition

This 3-day-old newborn presents with signs concerning for neonatal sepsis. The vital signs are significant for a temperature of 96.8°F (36.0°C), which represents hypothermia, a heart rate of 170 bpm (tachycardia), and a respiratory rate of 65 breaths per minute (tachypnea). In neonates, the inability to maintain a normal body temperature, particularly with a low or unstable temperature, is a classic and often more reliable sign of serious infection than fever [3]. These clinical markers, combined with the high index of suspicion in a NICU setting, fulfill the criteria for initiating the sepsis management pathway.

Rationale for Immediate Antibiotic Administration

The most appropriate immediate nursing intervention is to initiate broad-spectrum antibiotic therapy as prescribed. The foundational principle in sepsis management, strongly supported by international guidelines, is that early and effective antimicrobial therapy is a critical determinant of survival. The Surviving Sepsis Campaign pediatric guidelines explicitly recommend that administration of empiric broad-spectrum antibiotics should be initiated as soon as possible, ideally within one hour of recognition, especially in patients with septic shock or a high likelihood of sepsis [3]. The task force that developed the updated pediatric sepsis criteria also emphasizes that sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection, making time-sensitive intervention paramount . Delaying treatment to wait for culture results, as suggested in option 1, is contraindicated because a delay in antibiotic administration is directly associated with increased mortality. Blood cultures are a crucial diagnostic step to identify the causative organism, but they should never delay the initiation of therapy.

Analysis of Incorrect Options

- Option 1 (Wait for blood culture results): This action is dangerous and contradicts the core sepsis guideline recommendation for immediate, empiric treatment. Culture results take 24-72 hours, a period during which the patient’s condition can deteriorate rapidly without antimicrobial coverage [3].

- Option 3 (Increase ambient temperature): While providing a neutral thermal environment is an important supportive care measure to reduce metabolic demand, it does not address the underlying pathophysiology of sepsis. The hypothermia is a symptom of the dysregulated host response to infection, not a primary environmental problem. The priority is to treat the infection causing the thermal instability .

- Option 4 (Restrict fluid intake): This is not a standard initial intervention for suspected sepsis without clear signs of fluid overload. In fact, the initial hemodynamic management of pediatric septic shock often involves cautious fluid resuscitation to restore perfusion, not restriction, unless there is evidence of volume overload or specific contraindications [3]. Restricting fluids in a patient who may have increased insensible losses from tachypnea and a capillary leak could worsen their hemodynamic status.

Nursing Priority and Guideline Integration

The nurse's immediate role is to recognize the clinical signs of sepsis and act as the patient's advocate by ensuring timely implementation of the prescribed medical treatment. The 2008 Surviving Sepsis Campaign guidelines established the precedent that early goal-directed therapy, including prompt antibiotics, is the cornerstone of sepsis management . This principle has been reinforced and refined in subsequent pediatric-specific guidelines, which stress that the recognition of sepsis should trigger an immediate clinical response bundle that includes obtaining blood cultures, starting empiric broad-spectrum antibiotics, and measuring lactate, all within a strict timeframe [3]. The nurse must prioritize the administration of the prescribed antibiotics as the intervention with the highest impact on patient survival.References (research sources)

## 임상 시나리오

Neonatal Sepsis: Immediate Antibiotic InitiationTime-critical intervention for suspected sepsis in the NICU
For a newborn with suspected sepsis presenting with temperature instability (e.g., hypothermia of 36.0°C), tachycardia, and tachypnea, the priority is to administer broad-spectrum antibiotics as prescribed.

The Surviving Sepsis Campaign guidelines mandate that empiric antibiotics be started within 1 hour of recognition. Do not delay treatment while waiting for blood culture results.

CautionHypothermia, not fever, is a classic sign of serious infection in neonates. Supportive care like rewarming is secondary and must not postpone the administration of the first antibiotic dose.

## 핵심 개념

- **Neonatal Sepsis** — A life-threatening bloodstream infection in newborns within the first 28 days of life, often presenting with non-specific signs like temperature instability, respiratory distress, and lethargy.
- **Empiric Antibiotic Therapy** — Broad-spectrum antibiotics initiated before the specific causative organism is identified, based on the most likely pathogens for the clinical scenario.
- **Surviving Sepsis Campaign Guidelines** — International, evidence-based guidelines recommending that administration of IV antibiotics be initiated within 1 hour of sepsis recognition to reduce mortality.
