33
Q

Ulcer

A

A skin ulcer is a sore on the skin. Skin ulcers often form when blood circulation is impaired. Bed sores

34
Q

Stages of Bed Sores ( 4)

A

Stage 1 - epidermis
stage 2- dermis
stage 3 - subcutaneous tissue, fat
stage 4- muscle & bone

35
Q

Who is at risk for bed sores

A

IMMOBILE PATIENTS

INCONTINENT PATIENTS

36
Q 
Braden Scale (6 risk factors)
whats good/whats bad
A

six major risk factors:

  1. sensory perception
  2. moisture
  3. activity
  4. mobility
  5. nutrition
  6. Friction/Sheer.

lower the score, the more likely the patient will develop a pressure ulcer.
18< risk
12< HIGH RISK

Asses upon admission and again 48-72 hours

37
Q

Assessing moles for cancer

ABCDE-EFG

A 
Asymmetry of one side to the other
Borders-irregular=bad
Change in color
Diameter >6 mm =bad
Evolving over time
-
Elevated
Firm to palpation
Growing progressively
38
Q

Pruritus

39
Q

Reactive hyperemia

A

is the transient increase in organ blood flow that occurs after a period of ischemia (ex: arterial occlusion)

40
Q

linear

41
Q

Geographic

A

scalloped boarders, resembling the boarders of a map

42
Q

gyrate

43
Q

target

multiple rings- bullseye

44
Q

zosteriform

A

follows nerve root

45
Q

annular

A

ring like arrangement

46
Q

discrete

A

separate distinct lesions, not joined to one another

47
Q

Arciform

A

Arch shape

48
Q

serpiginous

A

(of a skin lesion or ulcerated region) having a wavy margin.

49
Q

Paronychia

A

infection of the skin folds around the nails

50
Q

Leukonychia

A

transverse white lines, commonly known as Mees lines in the nails

51
Q

Q

Classification of wounds (5)

A
  1. Open/Closed
  2. acute/chronic
  3. clean/contaminated/Infected
  4. superficial/partial or Full thickness
  5. Penetrating
55
Q

Primary Intention

A

edges are approximated

examples: Surgical incisions, paper cuts, and small cutaneous wounds usually heal by primary closure. - Minimal scarring

56
Q

Secondary intention

A

wound edges not approximated
tissue loss
heals from inner layer to surface

requires a granulation tissue matrix to be built to fill the wound defect.

57
Q

Tertiary intention

A

granulating tissue brought together

delayed closure of wound edges

58
Q

Regeneration

A

In epidermal wounds

NO scar

59
Q

Partial Thickness wound repair (3)

A
  1. inflammatory response ( vasodilation, redness, swelling, moderate amount of serous exudate
  2. Reproduction, migration and reestablishment of epidermal layers
  3. reestablishment of epithelial layers
60
Q

Full thickness wound repair (4)

A
  1. Hemostasis- control blood loos, establish bacterial control, seal defect
  2. Inflammatory response- vasodilation, exudate
  3. proliferative healing- granulated tissue, contraction of wound, surface repair
  4. remodeling- final stage, scar tissue
61
Q

Important labs for Wounds
