A 6-year-old child is admitted to the burn unit with second-degree burns covering 25% of the total body surface area (TBSA) from a house fire. The child is in the acute phase of burn injury. Which nursing intervention should be the priority during this phase?

해설
During the acute phase of burn injury, maintaining fluid and electrolyte balance is the highest priority to prevent hypovolemic shock and organ failure. Other interventions like nutrition, infection prevention, and pain management are important but secondary in this phase.

Core Nursing Explanation Key Concept Analysis: This question tests the priority nursing intervention for a pediatric patient in the acute (emergent/resuscitative) phase of a major burn injury. The core theme is understanding the pathophysiological sequence of events following a burn. The acute phase begins immediately after the injury and lasts 24-72 hours. The primary threat is hypovolemic shock due to massive capillary leak, which causes a rapid shift of intravascular fluid, proteins, and electrolytes into the interstitial space (third spacing). This leads to decreased cardiac output, hypotension, and potential organ failure. For a child with 25% TBSA second-degree burns, this risk is significant and life-threatening.

Answer Rationale: Key Point! The correct answer is 4 because fluid resuscitation is the absolute priority in the first 24-48 hours. The nurse must meticulously monitor intake and output (I&O), vital signs, urine output (target: 1 mL/kg/hr in children), and electrolyte levels (especially sodium and potassium) to guide IV fluid replacement, often using formulas like the Parkland formula. This directly addresses the primary threat to life.

Distractor Analysis:
Watch out for confusion! Option 1: While high-protein, high-calorie nutrition is crucial for wound healing, it is a priority in the later (rehabilitative) phase, not the acute phase. In the first 24-48 hours, gut function is often impaired (paralytic ileus), making aggressive oral intake inappropriate.
• Option 2: Infection prevention with topical antibiotics is vital but is a secondary priority after establishing hemodynamic stability. Wound care typically begins after initial resuscitation.
• Option 3: This represents poor pain management practice. Burn pain is severe and requires scheduled, proactive analgesia, not PRN (as-needed) dosing. Pain management is a high priority for comfort and to reduce metabolic stress, but it does not supersede the immediate need for fluid resuscitation to prevent shock.

Related Concepts: The "Rule of Nines" for estimating TBSA in adults differs for children due to their larger head-to-body ratio. The priority of care follows the ABCs (Airway, Breathing, Circulation) of emergency management. In burn injuries, airway assessment for inhalation injury is always the first priority, but the question specifies the child is already admitted, implying airway is secure, making circulation/fluid status the next priority.
Concept SummaryPhases of Burn Injury: 1) Emergent/Resuscitative (0-72 hrs): Shock prevention. 2) Acute/Wound Healing (After fluid stabilization): Infection control, wound care, nutrition. 3) Rehabilitative (From healing onward): Function, scarring, psychosocial support.
Pathophysiology of Acute Phase: Capillary leak → Third spacing → Hypovolemia → Shock.
Nursing Priorities (Acute Phase): 1) Airway & Breathing (Inhalation injury). 2) Fluid Resuscitation (Circulation). 3) Pain Management. 4) Wound Care & Infection Prevention.

Anatomy, Physiology & Pharmacology PointsPhysiology: Burn injury releases inflammatory mediators (histamine, prostaglandins) that dramatically increase capillary permeability. This causes the loss of intravascular volume and proteins (like albumin) into tissues, leading to edema and low blood volume.
Pharmacology (Fluids): Lactated Ringer's (LR) is the crystalloid fluid of choice for initial burn resuscitation because its electrolyte composition is similar to plasma and it helps correct metabolic acidosis.
Calculation: The Parkland Formula: 4 mL LR x kg body weight x %TBSA burned. Half is given in the first 8 hours post-burn, the second half over the next 16 hours.
Memory TipsAcronym for Burn Priorities: "ABCs and Fluids First!" (Airway, Breathing, Circulation/Fluids).
Phases Mnemonic: "Rescue with Fluids (Resuscitative) → Heal the Wound (Acute) → Rehabilitate (Rehabilitative)."
High-Frequency NCLEX Topics Burns are a high-yield topic. The NCLEX loves to test: 1) Prioritization (Fluids before food/wound care). 2) TBSA calculation (especially in children). 3) Signs of adequate fluid resuscitation (e.g., urine output). 4) Differentiating phases of care.
Watch Out for Question Variations! • Instead of asking for the priority intervention, a question might ask: "Which assessment finding indicates effective fluid resuscitation?" (Answer: Urine output of 1 mL/kg/hr).
• Or: "The nurse is calculating fluid needs using the Parkland formula. What is the total volume for the first 24 hours for a 20 kg child with 30% TBSA burns?" (Answer: 4 x 20 x 30 = 2400 mL).
• It could also shift to: "Which finding is a priority to report in the acute phase?" (Answer: Urine output < 1 mL/kg/hr, indicating inadequate resuscitation).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse in the Pediatric Burn Unit. A 6-year-old, 20 kg child named Leo is 4 hours post-injury with 25% TBSA partial-thickness (second-degree) burns to his chest and arms. He has two large-bore IVs infusing Lactated Ringer's. He is alert but anxious, with a heart rate of 130 bpm, blood pressure of 92/50 mmHg, and a Foley catheter in place.

Nursing Intervention Strategy:
1. Assessment: Perform focused assessments every hour. Monitor: Hourly urine output (goal: 20 mL/hr for this 20 kg child), vital signs, capillary refill, lung sounds (for pulmonary edema from over-resuscitation), and level of consciousness. Weigh the child daily (same scale, same time).
2. Fluid Management: Calculate the 24-hour fluid requirement using the Parkland formula (4 mL x 20 kg x 25% TBSA = 2000 mL). Administer 1000 mL in the first 8 hours (from time of burn) and the remaining 1000 mL over the next 16 hours. Use an IV pump for precise control. Document strict I&O.
3. Pain Management: Administer IV opioids (e.g., morphine) on a scheduled basis and before wound care procedures. Use pain scales appropriate for children (e.g., FACES scale).
4. Wound & Infection Prevention: Once hemodynamically stable (usually after 24-48 hrs), perform wound care per protocol (gentle cleansing, application of prescribed topical antimicrobial like silver sulfadiazine). Maintain strict aseptic technique.
5. Nutrition: Collaborate with a dietitian. Initiate enteral nutrition via a feeding tube if oral intake is insufficient to meet hypermetabolic demands, which can be 1.5-2 times the basal caloric need.

Patient Safety and Precautions: Never apply ice to burns. Keep the child warm (burns disrupt thermoregulation). Be vigilant for signs of compartment syndrome from circumferential burns (severe pain, pallor, paresthesia, pulselessness). Elevate burned extremities to reduce edema.
Nursing Procedure & Medication Flow Fluid Resuscitation Monitoring Procedure:
1. Ensure patent, large-bore IV access (e.g., 18-20 gauge).
2. Program IV pump with the calculated fluid rate.
3. Measure urine output hourly via Foley catheter. Report if < 1 mL/kg/hr.
4. Assess for signs of under-resuscitation (low UOP, tachycardia, hypotension) and over-resuscitation (crackles in lungs, increased edema, shortness of breath).
5. Monitor serum electrolytes, especially sodium (risk of hyponatremia) and potassium (risk of hyperkalemia from cell damage).

Medication Caution: Topical antimicrobials like silver sulfadiazine are contraindicated in patients with sulfa allergies. Monitor for leukopenia with its use.
A Word from Your Senior Nurse "In the burn unit, the first 24 hours are a race against time to replace what's leaking out. Your most critical tool is not the wound dressing—it's the I&O sheet and your stethoscope. That hourly urine output number tells you if your patient's kidneys (and by extension, their entire body) are getting enough blood flow. Never forget the simple measures: weigh them daily, listen to their lungs, and keep them warm. Mastering this acute phase management is what turns a life-threatening injury into a survivable one. On the NCLEX, they're testing if you know what kills first. In practice, you're using that knowledge to stop it."
