A 4-year-old child is admitted to the pediatric burn unit with second-degree burns covering 25% of the total body surface area (TBSA) from a house fire. The child is crying, restless, and has the following vital signs: temperature 100.2°F (37.9°C), heart rate 140 bpm, respiratory rate 32/min, and blood pressure 90/50 mmHg. What is the nurse's priority action?

Establishing IV access and fluid resuscitation is the priority for a pediatric burn patient with 25% TBSA burns to prevent hypovolemic shock. Pain management, cool dressings, and history-taking are secondary to hemodynamic stabilization.

Core Nursing Explanation Key Concept Analysis: This question tests the nursing priority for a major pediatric burn. The core principle is the Key Point! ABCs (Airway, Breathing, Circulation) of emergency care. In burn patients, especially with >20% TBSA (Total Body Surface Area) involvement, the primary threat to life in the first 24-48 hours is not the burn wound itself, but hypovolemic shock due to massive fluid shifts from the intravascular space into the interstitial tissues (third-spacing). The child's vital signs (tachycardia, tachypnea, borderline hypotension) are early signs of impending shock, making fluid resuscitation the immediate priority.

Answer Rationale: The correct answer is Establish IV access and begin fluid resuscitation. For a child with 25% TBSA second-degree burns, the Parkland formula (4 mL x kg x % TBSA burned) is used to calculate the 24-hour fluid resuscitation volume, with half given in the first 8 hours. Establishing IV access is the critical first step to deliver this life-saving therapy. The nurse's priority is to prevent circulatory collapse, which takes precedence over all other interventions.

Distractor Analysis:
• Watch out for confusion! Administer prescribed pain medication: While crucial for humane care and reducing stress (which can worsen shock), pain management is a secondary priority after securing the airway and IV access for fluid resuscitation. Medication administration often requires a patent IV line, and analgesics can potentially lower blood pressure further in a hypovolemic patient.
• Watch out for confusion! Apply cool, wet dressings: This is appropriate for minor, localized burns to stop the burning process. For major burns (>10% TBSA in children), applying cool dressings over a large area can lead to hypothermia, which worsens shock and coagulopathy. The priority is systemic stabilization, not local wound cooling.
• Watch out for confusion! Obtain a detailed history: A history is important for the medical record and to identify potential inhalation injury or abuse, but it is not the immediate life-saving action. The ABCs always come first. A focused, rapid assessment is done concurrently with interventions.

Related Concepts: The scenario also hints at potential inhalation injury (house fire), which would make securing the airway an even higher priority than circulation. However, the question stem does not present overt airway symptoms (stridor, soot in nares, hoarseness), so based on the given data, circulatory support is the clear priority. The child's restlessness and crying could be due to pain but are also classic signs of early hypoxia or hypovolemia.
Concept Summary • Rule of Nines for Pediatrics: For children, the head represents a larger percentage (18%) and the legs a smaller percentage than in adults. Accurate TBSA estimation is critical for fluid calculations.
• Burn Shock Pathophysiology: Burn injury increases capillary permeability → massive fluid and protein leak into interstitial space (edema) → decreased intravascular volume (hypovolemia) → decreased cardiac output → shock.
• Parkland Formula: 4 mL x Patient's weight (kg) x % TBSA burned. Give ½ of total in first 8 hours from time of burn, remaining ½ over next 16 hours. Use Lactated Ringer's (LR) as the initial fluid of choice.
• Nursing Priorities (Burn): 1. Airway & Breathing (100% O2 if inhalation suspected), 2. Circulation (IV access/fluids), 3. Wound Care & Pain Management, 4. Prevention of Complications (infection, compartment syndrome).

Very minor burns (140, RR >30, and systolic BP 임상 시나리오 Nursing Clinical Practice Guide Clinical Scenario: You are the nurse receiving a 4-year-old, 18 kg child via ambulance. The child is wrapped in a clean sheet, crying inconsolably. Paramedics report 25% TBSA mixed partial-thickness (second-degree) burns to the chest, abdomen, and right arm from a house fire. No obvious airway distress noted en route. Nursing Intervention Strategy: 1. Rapid Primary Survey (ABCs): While listening to report, visually assess airway (no stridor), breathing (rate and effort), and circulation (palpate peripheral pulse, check capillary refill >2 seconds). 2. Immediate Action: Call for help and establish two large-bore IV lines (if possible) in unburned areas. Begin infusing Lactated Ringer's per the Parkland protocol. For this child: 4 mL x 18 kg x 25% = 1800 mL total in 24 hours. First 8-hour volume = 900 mL, rate = ~113 mL/hr. 3. Concurrent Assessments: Attach monitor (HR, BP, SpO2), insert Foley catheter to strictly monitor urine output (goal: 18 mL/hr). Obtain weight. Keep child warm with a radiant warmer or warm blankets to prevent hypothermia. 4. Secondary Priorities: Once IV is running and vitals are being monitored, administer IV opioid analgesia (e.g., morphine) as ordered for pain. Begin a focused history from parents/EMS. Gently clean and cover burns with sterile, non-adherent dressings (e.g., silver sulfadiazine) as per unit protocol. Patient Safety and Precautions: • Never apply ice or very cold water to major burns. • Calculate IV drip rates accurately and use an infusion pump. Fluid needs are dynamic and require hourly reassessment. • Monitor for compartment syndrome, especially with circumferential burns. Assess pulses, sensation, and movement distal to the burn hourly. • Use strict aseptic technique for all wound care. Burn patients are profoundly immunocompromised. Nursing Procedure & Medication Flow Procedure: Establishing IV Access in a Pediatric Burn Patient 1. Select site: Unburned area (foot, saphenous vein) if possible. If only burned sites are available, intraosseous (IO) access may be needed. 2. Use the largest bore catheter possible (e.g., 22g or 20g). 3. Secure meticulously with a transparent dressing for visibility. 4. Label the line clearly. Medication: IV Morphine for Pain • Dose is weight-based (e.g., 0.05-0.1 mg/kg). For 18 kg: 0.9 - 1.8 mg. • Administer slowly IV push, monitoring for respiratory depression, especially after initial fluid resuscitation improves perfusion. • Always have naloxone (Narcan) available. A Word from Your Senior Nurse "In the chaos of a burn admission, your calm, systematic approach is everything. Remember your ABCs like a mantra. That crying, restless child isn't just in pain—their body is fighting to maintain blood pressure. Getting that IV line in and fluids running is the single most important thing you can do in those first minutes. In clinicals and on the NCLEX, when you see 'major burn' and 'pediatric,' let your brain immediately shout 'FLUIDS!' It’s that connection between pathophysiology (capillary leak) and nursing action (IV resuscitation) that makes you a safe, thinking nurse." 핵심 개념 Hypovolemic Shock — A life-threatening condition where severe blood or fluid loss makes the heart unable to pump enough blood to the body, leading to organ failure. In burns, it's caused by massive fluid shifts from the bloodstream into tissues. Parkland Formula — The standard calculation (4 mL x kg x % TBSA burned) for the volume of Lactated Ringer's solution required for the first 24 hours of fluid resuscitation in a major burn patient. Total Body Surface Area — The percentage of the body affected by burns, estimated using tools like the Rule of Nines. It is the critical factor determining the need for IV fluid resuscitation. Capillary Permeability — The tendency of capillaries to leak fluid and proteins into the surrounding tissues. It is dramatically increased after a major burn injury, causing edema and intravascular volume depletion. Inhalation Injury — Damage to the respiratory tract from breathing in hot air, smoke, or toxic chemicals. A key concern in fires, it can cause airway swelling and is a primary cause of death in burn patients. 마이메르시로 국가고시 완벽 대비 기출문제와 상세 해설을 무료로. 내 약점을 분석하고 진도를 관리하며 더 똑똑하게 공부하세요. 무료로 시작하기 App Store Google Play 학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요.
