A 6-year-old child sustained second-degree burns covering 15% of the body surface area from a house fire. During the acute phase of burn management, which nursing intervention should be the highest priority?

## 보기

1. Administer prescribed analgesics to manage pain and discomfort
2. Monitor vital signs every hour to detect early changes
3. Maintain strict intake and output monitoring with hourly urine measurements **✔ 정답**
4. Apply topical antimicrobial agents to prevent wound infection

**정답: 3**

## 해설

In the acute phase of pediatric burns, fluid resuscitation and monitoring are the highest priority to prevent hypovolemic shock, with hourly urine output being the most reliable indicator. Pain management, vital signs monitoring, and wound care are secondary until hemodynamic stability is achieved.

Understanding the Acute Phase of Burn Injury

For a child with 15% second-degree burns, the acute phase begins approximately 36–48 hours after the injury, once the initial fluid shift starts to resolve. However, the immediate post-burn period is dominated by a massive systemic inflammatory response. This triggers a profound capillary leak, where fluid, electrolytes, and proteins shift from the intravascular space into the interstitial tissues. This phenomenon, known as burn shock, leads to life-threatening hypovolemia, decreased cardiac output, and inadequate end-organ perfusion if not aggressively managed. The highest priority during this critical window is to preserve vital organ function, particularly the kidneys, which are highly sensitive to hypoperfusion [1].

Why Fluid Resuscitation Monitoring is the Priority

The correct answer is maintaining strict intake and output with hourly urine measurements. In the context of burn shock, traditional clinical indicators like blood pressure and heart rate are often late signs of hypovolemia and can be misleading due to compensatory vasoconstriction. The most reliable and practical bedside indicator of adequate fluid resuscitation and end-organ perfusion is urine output (UOP). For a 6-year-old child, the goal is typically to maintain UOP at 1.0–1.5 mL/kg/hour. Hourly monitoring allows the nurse to titrate IV fluid rates precisely, a concept central to modern burn fluid protocols. While invasive monitoring like PiCCO or PAC can provide more direct hemodynamic data, they carry risks of infection and require specialized expertise, making meticulous UOP monitoring the safest and most effective primary nursing intervention to prevent acute kidney injury and ensure survival [1].

Analysis of Other Options

- **Option 1 (Administer prescribed analgesics):** Pain management is a crucial component of holistic burn care, but it is secondary to hemodynamic stabilization. Severe pain can be managed with IV opioids only after adequate tissue perfusion is ensured, as vasoconstriction from shock can alter drug absorption and metabolism. Addressing physiological instability takes precedence.

- **Option 2 (Monitor vital signs every hour):** While vital sign monitoring is important, it is a component of assessment, not a direct intervention. More critically, a child in burn shock may maintain a normal blood pressure until 30% or more of circulating volume is lost, making it an insensitive marker. The intervention that directly guides life-saving therapy is the titration of fluids based on hourly UOP.

- **Option 4 (Apply topical antimicrobial agents):** Wound care and infection prevention are priorities in the sub-acute and rehabilitative phases. In the initial acute phase, the immediate threat to life is hypovolemic shock, not infection. Topical agents are applied after initial debridement and stabilization of the patient's hemodynamic status.

Connecting the Evidence to NCLEX Practice

This question tests the NCLEX principle of Maslow's Hierarchy of Needs within a physiological crisis. The narrative review on fluid management confirms that "precise and timely fluid management is essential for survival" in severe burns and that urine output remains a cornerstone clinical indicator despite its limitations [1]. For the NCLEX, you must recognize that in the acute phase of a burn, airway, breathing, and circulation are paramount. Within circulation, the most direct nursing intervention to ensure adequate fluid resuscitation is strict I&O with hourly urine measurements, as this data point drives the clinical decision-making to prevent irreversible shock and renal failure.

Pediatric Burn Fluid Resuscitation MonitoringPrioritizing Hourly Urine Output in the Acute Phase
During the acute phase of burn injury, burn shock from massive capillary leak makes urine output (UOP) the most reliable indicator of fluid resuscitation adequacy. For a 6-year-old child, the target UOP is 1.0–1.5 mL/kg/hour.

Vital signs like blood pressure and heart rate are late signs of hypovolemia and can be misleading due to compensatory vasoconstriction. Hourly UOP monitoring allows precise titration of IV fluids.

CautionDo not rely solely on vital signs to assess perfusion in burn patients. A decrease in UOP is an early warning sign of inadequate renal perfusion and requires immediate adjustment of fluid rates.

## 핵심 개념

- **Burn Shock** — A state of profound hypovolemia and decreased cardiac output caused by a massive systemic inflammatory response and capillary leak following a major burn.
- **Urine Output (UOP)** — The most reliable bedside indicator of adequate fluid resuscitation and end-organ perfusion; goal for a 6-year-old is typically 1.0–1.5 mL/kg/hour.
- **Acute Phase** — The period beginning 36–48 hours post-burn, dominated by fluid shifts and the resolution of burn shock, requiring intensive monitoring.
