Q

What is the difference between partial and full thickness burns?

A

Partial thickness (anything above subcutaneous tissue)
1st degree involves epidermis
2nd degree involves epidermis and dermis

Full thickness (subcutaneous tissue down to bone)
3rd degree involves epidermis and dermis down to subcutaneous fat, muscle and possibly bone

Q

What are the two major parts of injury in the emergent phase of a burn

A

Burn injury causes damage to tissue, then inflammatory response (increased capillary permeability) causes more issues such as:

fluid out of the intravascular space and into the interstitial spaces (third spacing)
Shift of electrolytes and possible necrosis of tissue
The immune system is also compromised because the skin is removed and the inflammatory process reduces the availability of the innate and specific immune systems

At risk of hypovolemic shock

Q

Manifestations of a Second degree Electrical Burn

A

May look superficial, but will have internal injuries that are more severe

17
Q

Manifestations of a Third degree Electrical Burn

A

Possible fractures or dislocations from muscle contraction

18
Q

What is the first intervention for a chemical burn

A

remove the source of the the chemical burn

19
Q

What are the secondary effects of major burns you should monitor for?

A

acute kidney injury

20
Q

What is a TBSA calculation

A

Total Body Surface Area (Rule of Nines)

21
Q

What are some medications you treat for the secondary effects of major burns

A

Analgesics
Sedatives
VTE prophylaxis
Tetanus immunization
Antibiotics/antimicrobials

Fluid therapy (use Parkland Formula)
Isotonic fluids-most commonly LR
Possible albumin administration

22
Q

What is the Parkland Formula

A

Determine fluid resuscitation for burn victims over the first 24 hours by:

multiplying 4ml times the percentage of body surface area times the patient’s weight in kg

multiply by .5 and give first half the first 8 hours and the second half the next 16 hours

If pt produces less than 30ml of urine/hr with current level of fluid therapy, tell doc. SHOULD have large diuresis as fluid shifts back into interstitial space

23
Q

Circumferential burns (compartment syndrome) often require what intervention?

A

Escharotomy or fasciotomy (allows swelling to occur without compromising circulation)

24
Q

What are the two types of wound care?

A

Open method: creams and salves with no dressing (around face and head)
Closed method: Burns have dressings

25
Q

T/F: You should always use sterile technique and provide pain medication when performing wound care on burn victims

A

True.

26
Q

What are the nursing priorities in order when a burn victim is in the emergent phase?

A

Monitor and manage airway
Provide oxygen support as needed
Establish IV access
Replace fluid therapy and monitor for effectiveness/over replacement
Strict I&O monitoring
Monitor for infection
Perform wound care
Monitor and prevent pressure injuries
Monitor and report abnormal lab values
Coordinate with PT/OT

27
Q

Describe the nutritional needs of a burn victim

A

hypermetabolic state, high calories diet

28
Q

Describe the sx of the acute phase of burn victim

A

Hyperglycemia r/t increased stress hormones can impede healing process

Increased urine output

increased pain level

29
Q

What are some lab manifestations of the acute phase of burn victims

A

Monitor for hemodilution

May change from hyponatremic to hypernatremia and hyperkalemic to hypokalemic. Must monitor chem panel

Elevated WBC and ESR/CRP

Hyperglycemia

ABGs

30
Q

Describe the changes in pharmacology for the acute phase of a burn

A

Starting to wean off of narcotics (pain meds) and sedation if possible
Try switching to PO fluid/electrolyte replacement
VTE prophylaxis
Antibiotics/antimicrobials
Continue monitoring glucose, may use insulin to control

31
Q

What type of wound care would a nurse perform during the acute phase

A

Manual debridement or with enzymes
Excision (escharectomy) (prep for graft)
Skin Grafting

32
Q

How do you prep a burn patient for OT/PT

A

Remove dressings to increase possible ROM

Will possibly have splints etc. to prevent contractures

33
Q

What is a Allograft

A

Try Cadaveric skin to see if pt will accept transplant at all

TEST TO DO AUTOGRAFT, NOT PERMANENET

34
Q

What is a Autograft

A

Skin taken from patient if there is enough

Skin grafts are typically meshed which allows the graft to cover a larger area

35
Q

What do you do if there is not enough skin available to make a graft

A

Possible cultured epithelial autograft (CEA).

Dermal Substitute
Different types that may be permanent or used as a bridge for a severely burned patient waiting on CEA

36
Q

T/F: The burn site is often more painful than the donor site

A

False: Donor site if often more painful than burn site

37
Q

What are the common complications found in burn patients?

A

Paralytic ileus
Contractures
Constipation
Curling’s ulcer (Burns cause a reduction in plasma volume, which can lead to ischemia and cell death in the stomach lining)
Hyperglycemia

38
Q

Itching, pain, skin flaking are manifestations of what phase of burn healing

A

Rehabilitation Phase
