    • 72 hours 
    • Lavage areas with lots of water
    • Scrape away dry chemicals
  3. What are the three types of smoke inhalation injury?
    What will each look like?
    • CO poisoning: metabolic asphyxiation (CO takes up O2 sites in hemoglobin
    •  - n/v, fatigue, SOB, HA
    • Upper airway (above glottis): drooling, hoarseness, stridor
    • Lower airway (below glottis):
    • suspect if wheezing, labored breathing, rales, cough
  4. 1. How can electrical burns cause damage to tissues?
    2. Vfib or asystole most common?
    3. What is Myoglobinuria? What is its clinical manifestation?
    4. How much urine output do you want to have with this type of burn?
    • 1. Direct damage to nerves and vessels, and organs causing tissues necrosis
    • 2. Vfib most common
    • 3. Myoglobinuria: tubular necrosis from electrical burn that leads to kidney failure
    •  - Cinical manifestation: brown urine
    • 5. 75-100 ml/hr
  5. Match: redness, blanching on pressure. 
    Tactile sensation intact
    Pain
    Involves epidermis



    A.
  6. Match depth of burn: 
     - Blisters
     - Severe pain, edema
     - Involves Epidermis and dermis
     - Skin red, pink, wet, shiny seeping


    B.

  8. 1. When assessing TBSA, which one is the most accurate?
    2. Which one is used frequently for initial assessment?
    • 1. Lund browder
    • 2. Rule of 9
  9. Location of burn: how will each location of burn affect the patient

    1. Burn to face, neck, or torso
    2. Extremities
    3. Perineum, nose, and ears
    • 1. respiratory problems
    • 2. circulation hindered at hands and feet d/t swelling
    • 3. Prone to infection
  10. Prehospital care phase, first thing you do?
    Difference between a small and large thermal interventions?
    Other interventions?
    • First thing: Remove from burn source
    • Small (<10%): clean, cool tap water
    • Large: ABCs, don't use water, cover with dry sheet or blanket
    • Others: fluids and pain management
  11. 1. Describe the fluid emergent phase (Hypovolemic shock and edema formation)
    2. Reason for for hypovolemia and edema?
    3. What will Na and K look like?
    • Lasts 48-72 hours; 200-400ml/hr of water insensible loss
    • Reason for shift: Massive fluid shifts out of blood vessels d/t increased capillary permeability
    • Decreased serum Na, and increased K
  12. What will happen to each with increased permeability in a burn victim?
    1. Fluid shift: in or out of vessels
    2. Blood volume
    3. HcT (higher or lower)
    4. Viscocity
    • 1. Fluid shifts out of vessels (edema)
    • 2. Hypovolemia
    • 3. Higher HcT
    • 4. Higher blood viscosity
  13. How do you severe edema in a burn patient? (compromised blood flow causing edema)
    Escharotomy
  14. How can kidneys be damaged during emergent phase of burn?
    2 ways
    • Hypovolemic shock can lead to kidney ischemia (ATN)
    • Myoglobin breakdown obstructs tubules
  15. List collaborative management in emergent phase
    • Airway
    • Fluids
    • Wound care
    • pain/anxiety
    • early and aggressive nutritional support
    • DVT prophyalxis
  16. Why are DVTs higher risk in burn patients?
    Blood becomes thicker (higher HcT and blood viscosity)
  17. List fluid therapy in emergent phase
    What does the HR need to stay above?
    What is the Parkland formula?
    • 2 Large bore IV
    • Give fluids if TBSA >15% (>10% in kids)
    • HR: 120
    • Parkland: 4ml x %TBSA x weight (kg)
  18. T or F: wound care in burn victims will be a sterile procedure

    What are other considerations?
    True

    • Other: put on gown and mask
    •  - keep room warm
    •  - admin tetanus shot
  19. Nutrition: how many kcal/day will a patient need? 
    How much will their metabolism increase by?
    • 5kcal/day
    • 50-100% increase
  20. Which pain med will you administer for wound care?




    C.
  21. What is look out for when giving Toradol?
    Cr and BUN
  22. What will you use instead of a systemic abx to treat infection?
    Silver sulfadiazine
  23. Describe the acute phase
    How many hours does it start at?
    How will fluid shift?
    Amount of time to heal?
    • Starts after 72 hours
    • Fluid shifts back into vascular system
    •  - Diuresis
    • Takes weeks to months to heal
  24. List tx for partial and full thickness wounds in acute phase
    • Partial: Eschar removed 
    •  - Epithelial buds (eventually close wound)
    • Full: 
    •  - require surgical debridement
    •  - skin grafting
    •  - pt. education 
    •  - psychosocial support
  25. During acute phase, how will sodium and potassium levels be affected?
    • Sodium: can be both high or low
    •  - hydrotherapy pulls Na from open wounds
    • K: 
    •  - Can be high if deep muscle injury
    •  - can be low if GI suction, vomiting, or diarrhea
  26. Which one of these will be the biggest concern in acute phase?




    A.
  27. How do you prevent contractures in acute phase?
    ROM, splints, stretch exercises
  28. How will BG be affected during acute phase?
    • Can be high, due to increased cortisol levels.
    •  - Give insulin instead of cutting down calories
  29. What are some GI issues that can occur while treating the acute phase?

    What is the first sign of a GI bleed?
    • Sepsis from ileus -> NG tube 
    • Diarrhea from supplemental feedings
    • Constipation from decreased mobiility and narcotics
    • GI ulcers
    •  - First sign in GI bleed is vomiting blood
  30. What is autograft?
    • Growing of patient's own skin from biopsy
    • Takes 18-25 days, expanding up to 10,000x
  31. What will rehab phase look like in burns?
    How long can it take?
    What will you do for patient?
    What will you tell patient to avoid?
    • Pt's wounds are healing
    • Collagen fibers present in scar tissue
    • Tissues become raised and hyperemic
    • Nursing:
    •  - ROM, splints, massages, and education
    •  - Education: stay out of sun, smoking cessation
  32. This type of garment will minimize hypertrophic burn scarring during rehabilitation phase
    Elastic pressure garments
