It is calculated as: Fluid Requirement (mL)=4×body weight (kg)×total BSA burned (%) Half of this amount is given over the first 8 hours from the time of burn injury, and the remaining half is given over the next 16 hours. **Rationale**: This formula helps prevent hypovolemic shock by restoring circulating volume, maintaining tissue perfusion, and preventing organ failure. 2\. **Rule of Nines -- BSA Calculation**    Answer: The rule of nines is a method used to estimate the total body surface area (TBSA) affected by burns. It divides the body into sections, each representing 9% or multiples of 9% of the total body area:    - Head and neck: 9%    - Each arm: 9%    - Each leg: 18%    - Anterior trunk: 18%    - Posterior trunk: 18%    - Genital area: 1%    Rationale: Accurately estimating TBSA is critical for guiding fluid resuscitation and treatment. 3\. **Medications for Burn Management**    Answer:    - Pain management: Opioids like morphine or fentanyl.    - Infection prevention: Topical antibiotics like silver sulfadiazine, systemic antibiotics as needed.    - Sedatives: For anxiety and agitation, benzodiazepines like lorazepam.    - Antipruritic medications: Antihistamines like diphenhydramine for itchiness.    Rationale: Pain control, prevention of infection, and comfort management are essential in the holistic care of burn patients. 4\. **Carbon Monoxide Poisoning** Answer: Carbon monoxide binds to hemoglobin more readily than oxygen, leading to hypoxia. Symptoms include headache, dizziness, nausea, confusion, and cherry-red skin coloration in severe cases. Treatment: involves high-flow 100% oxygen or hyperbaric oxygen therapy.    Rationale: Prompt treatment is essential to prevent tissue hypoxia and death. 5\. **Phases of Burn Care and Related Priority Interventions**    Answer: - [Emergent Phase:] First 24-48 hours. Priority: Airway, breathing, circulation, fluid resuscitation, and pain management. - [Acute Phase:] From diuresis to wound closure. Priority: Wound care, prevention of infection, pain control, and nutrition. - [Rehabilitation Phase:] After wound closure. Priority: Psychological support, physical therapy, and scar management.   Rationale: Different phases focus on stabilizing the patient, wound healing, and long-term recovery. 6\. **Types of Burns and Management**    Answer: - First-degree burns: Superficial, only epidermis affected. Management: Cool compresses, analgesics. - Second-degree burns: Partial thickness, epidermis, and part of the dermis. Management: Wound care, pain control, possible antibiotics. - Third-degree burns: Full thickness, affecting all skin layers. Management: Surgical interventions like grafting, intensive wound care.   Rationale: Management varies with the depth and severity of the burn. 7\. **Lab Values and Their Relationships to Burns/Burn Phases**    Answer: - [Electrolytes:] Hyponatremia or hyperkalemia common in the emergent phase due to fluid shifts. - [CBC:] Elevated WBCs in infection, decreased hematocrit due to hemolysis. - [BUN/Creatinine]: Monitored for renal function.    Rationale: Lab values guide fluid and electrolyte management and detect complications. 8\. **Prioritization of Burn Patients**    Answer: Airway management (especially with facial burns/inhalation injury) \> Fluid resuscitation \> Pain management \> Infection prevention.    Rationale: Airway and circulation are immediate life threats. 9\. **Risk for Burns Across the Lifespan**    Answer: - [Children]: Scald injuries from hot liquids. - [Elderly:] Decreased mobility and sensory perception.    Rationale: Age-specific factors increase burn risk, requiring targeted prevention. 10\. **Prevention of Burns/Education**    Answer: Use of smoke alarms, safe cooking practices, water heater temperature settings, and protective gear.    Rationale: Education reduces incidence and severity of burns. 11\. **Priority Actions for Patient with Fluid & Electrolyte Imbalances**    Answer: Monitor vital signs, fluid intake/output, and lab values. Administer appropriate IV fluids and electrolytes.    Rationale: Prevent complications like arrhythmias or shock. 12\. **Risk for AKI, CRF Across the Lifespan**    Answer: Dehydration in children, polypharmacy in elderly, existing comorbidities increase risk.   Rationale: Early recognition and management can prevent progression to chronic kidney failure. 13\. **Patient Teaching Diuretics** Answer: Take in the morning, monitor weight daily, report dizziness, muscle cramps. Maintain potassium intake if on non-potassium-sparing diuretics.   Rationale: Prevent adverse effects and ensure effective management. 14\. **Nephrotoxic Medications**   Answer: NSAIDs, aminoglycosides, contrast agents.    Rationale: Monitoring and minimizing use to protect kidney function. 15\. **Expected Findings with Abnormal GFR**   Answer: Elevated creatinine, uremic symptoms (fatigue, nausea), fluid overload. Rationale: Reduced GFR indicates impaired kidney function. 16\. **Management /Indications for Dialysis** Answer: Indicated for severe fluid overload, electrolyte imbalances (e.g., hyperkalemia), or uremic symptoms. Management includes monitoring fluid, electrolyte status, and access site care.   Rationale: Dialysis replaces kidney function in severe kidney failure. 17\. **Management of Fluid Volume Deficit/Overload**    Answer:    - Deficit: Administer IV fluids, monitor vital signs, urine output.    -Overload: Fluid restriction, diuretics, monitor respiratory status. Rationale: Proper balance is crucial for organ function. 18\. **Prioritization of Patients**   Answer: ABCs (Airway, Breathing, Circulation), severe pain, and high-risk patients (elderly, comorbidities). Rationale: Prioritize based on severity and potential for deterioration. 19\. **Renal Biopsy** Answer: Indicated for unexplained AKI, nephrotic syndrome. Post-procedure: Monitor for bleeding, bed rest. Rationale: Diagnosis of renal pathologies. 20\. **Third-spacing** Answer: Fluid shifts to interstitial spaces, seen in burns, sepsis. Management: Fluid resuscitation, monitor for signs of hypovolemia. Rationale: Can lead to decreased circulating volume and shock. 21\. **Dietary Teaching**    Answer: Low-sodium, low-potassium diet for renal patients. High-protein for wound healing in burns. Rationale: Diet tailored to condition aids in recovery and prevents complications. 1\. **Parkland Formula Calculation Practice Question** - **Question: A 70 kg adult patient presents with 40% total body surface area (TBSA) burns.
