When does hemostasis occur?
Immediately after injury.
Hemostasis increases perfusion causing ____ and ____.
Pain and swelling
What happens during the hemostasis phase of wound healing?
Blood clotting > same blood vessels dilate and capillary permeability increases > plasma and blood components leak out > exudate > swelling and pain.
How long does inflammation last?

How long does proliferation last?
Several weeks
What happens during the proliferation phase of wound healing?
Fibroblasts build new tissue, capillaries bring O2 and nutrients, and granulation tissue forms.

Irradiation
Blunt instrument, overlying skin remains intact, with injury to underlying soft tissue; possible resultant bruising and/or hematoma.
Contusion
Toxic agents such as drugs, acids, alcohols, metals, & substances released from cellular necrosis
Chemical
Friction; rubbing or scraping epidermal layers of skin; top layer of skin abraded.
Abrasion
Injury and underlying diabetic neuropathy, peripheral arterial disease, diabetic foot structure
Diabetic Ulcers
Tearing a structure from normal anatomic position; possible damage to blood vessels, nerves, and other structures
Avulsion
Injury and underlying ischemia, resulting from underlying conditions, such as atherosclerosis or thrombosis
Arterial Ulcers
Blunt or sharp instrument puncturing the skin; intentional (such as venipuncture) or accidental
Puncture
High or low temperatures; cellular necrosis as a possible result
Thermal
Compromised circulation secondary to pressure or pressure combined with friction
Pressure Ulcers
Foreign object entering the skin or mucous membrane and lodging in underlying tissue; fragments possibly scattering through tissues.
Penetrating
Tearing of skin and tissue with blunt or irregular instrument; tissue not aligned, often with loose flaps of skin and tissue
Laceration
19-23 score on the braden scale is ____ risk.
No
What is low risk score on the braden scale?
15-18
13-14 score on the braden scale is what kind of risk?
Moderate
What is a high risk score on the braden scale?
10-12
Anything less than or equal to 9 is considered what kind of risk on the braden scale?
Very high risk
Intact skin with a localized area of nonblanchable erythema is a stage ____ pressure injury.
1
What is a stage 2 pressure injury?
- Partial-thickness loss of skin with exposed dermis.
- The wound bed is viable, pink, moist, and may also present as an intact or ruptured serum-filled blister.
- Adipose (fat) and deeper tissue are not visible.
- Granulation tissue, slough, and eschar are not present.
What stage of pressure injury is this explaining?
- Full-thickness loss of skin, adipose (fat) is visible in the ulcer, granulation tissue, and epibole (rolled wound edges) are often present.

- Epibole (rolled edges), undermining, and/or tunneling often occur. Depth varies.
Stage 4 pressure injury
What is an unstageable pressure injury?
- Full-thickness skin and tissue loss in which the extent of tissue damage within the ulcer cannot be confirmed because of slough or eschar.
- If slough or eschar is removed, a stage 3 or 4 pressure injury will be revealed.
Intact or nonintact skin with localized area of persistent nonblanchable deep red, maroon, or purple discoloration or epidermal separation revealing a dark wound bed or blood-filled blister. This is what kind of pressure injury?
Deep tissue pressure injury
____ ____ On admission assess the skin, then reassess every shift and with any change in condition.
