needed to meet increased metabolic demands and promote healing

37
Q

A scald is an example of which type of burn?

A

Second Degree

38
Q

Nursing Care re: Burns.

A
  • Prevent heat loss
  • Fluid balance and adequate hydration
  • Prevent infection
  • Pain management
  • Promote nutrition (increase protein and calories)
  • Dressings and ointments
39
Q

Phase of Burn:

First 24-48 hrs

A

Acute Phase (Fluid Resuscitation Phase)

40
Q

Phase of Burn:

Completion of adequate resuscitation through wound coverage

A

Management Phase

41
Q

Phase of Burn:

Begins once the majority of the wounds have healed.

A

Rehabilitation Phase

42
Q

Vaseline on burns?

A

NO, nothing w/ petroleum

COOL WATER!!!

43
Q

Why cover the burn w/ gauze?

A
  • to prevent contamination

- to alleviate pain by avoiding air contact

44

A

anti-inflammatory agent such as DECADRON (dexamethasone)

45
Q

Parkland Formula

A

The Parkland formula is a burn formula used to estimate the amount of replacement fluid required for the first 24 hours in a burn patient so as to ensure they remain hemodynamically stable.

2-4 mL/kg x TBSA

46
Q

47
Q

Methods of Wound Care:

Wound remains exposed to air after cleaning.

A

Exposure Therapy

48
Q

Methods of Wound Care:

Wound is resurfaced after cleaning.

A

Occlusive Dressing

49
Q

Methods of Wound Care:

Immediate debridement of necrotic eschar

Natural process of proteolytic degradation of tissues by body and bacterial enzymes

A

Primary Excision

50
Q

The immediate postburn period is marked by dramatic alterations in —

A

circulation (50% decrease circulation)

called burn shock,

51
Q

Why are children younger than 2 at an increased risk for dehydration when burned?

A

lack of ability to concentrate urine due to immaturity of kidneys

52
Q

Why are kidneys affected in burns?

A

Loss of fluid from the intravascular compartment causes renal vasocronstriction that in turn leads to reduced renal plasma flow and depressed GFR

53
Q

Why GI problems in burns?

A

Loss of blood volume decreases Blood Flow to GI system by 1/3 even when cardiac output is maintained by fluid resuscitation

Ischemia results, causing painful ulcers, enterocolitis

54
Q

How can we support the increased metabolism needs of burn victims?

A

increase protein and carbohydrates

55
Q

Most reliable indicators for assessing how well fluid resuscitation has workd?

A

Cap refill

alterations in sensorium

urinary output

56
Q

Grafts:

—- come from people (ex: cadavers or foreskin)

— come from different species (pigskin, etc.)

A

Allografts (homografts)

Xenografts (heterografts)

NOTE: Transcyte — come from bioengineered foreskin tissue (temporary)

57
Q

Types of Temporary Grafts:

A
  • Allografts (Homografts)
  • Xenografts (Heterografts)
  • Synthetic Skin Coverings
58
Q

When do burn scars become HYPERtrophic?

A

when no pressure was put on the skin graft

59
Q

Autograft (from own body)

Isograft (from twin)

60
Q
