1. Epidermis regeneration 4 to 6 weeks
time
2. Stratum germinativum Innermost epidermis layer that produces new cells, synthesizes ker-
(basale) atin, and contains melanin and Langerhans cells.
3. Rete Ridges Interconnected projections that anchor the epidermis to the dermis,
preventing them from sliding.
4. Subcutaneous Layer func- Provides insulation and cushioning, and attaches the dermis to un-
tion derlying muscle and bone using adipose tissue.
5. Capillary Closing Pressure Greater than 12 to 32 mmHg, causing tissue hypoxia and cell death
threshold when exceeded.
6. Braden Scale score indi- Lower than 18
cating risk
7. Norton Scale score indi- 10 or below
cating high risk
8. Stage 1 Pressure Injury Intact skin with nonblanchable erythema (redness that does not turn
white when pressed).
9. Stage 2 Pressure Injury Partial-thickness loss of skin with exposed dermis, viable
pink/red/moist wound bed, or serum-filled blister.
10. Stage 3 Pressure Injury Full-thickness skin loss with visible adipose tissue, granulation tissue,
and potential epibole, undermining, or tunneling.
11. Stage 4 Pressure Injury Full-thickness skin and tissue loss with directly palpable or exposed
fascia, muscle, tendon, ligament, cartilage, or bone.

Unstageable Pressure In- Full-thickness skin and tissue loss obscured by slough or eschar,
jury preventing the extent of damage from being confirmed.
13. Deep Tissue Pressure In- Intact or non-intact skin with a persistent, nonblanchable deep red,
jury (DTPI) maroon, or purple discoloration.
14. Primary Intention Healing Wounds with minimal tissue loss and approximated edges that heal
quickly with minimal scarring.
15. Secondary Intention Heal- Wounds with significant tissue loss that remain open and fill with
ing granulation tissue from the bottom and sides.
16. Tertiary Intention Healing A wound left open temporarily to allow edema or infection to resolve
before being surgically closed.
17. Inflammatory Phase dura- Begins immediately and lasts about 3 days.
tion
18. Proliferative Phase key Angiogenesis, collagen synthesis, wound contraction, and granula-
events tion tissue formation.
19. Maturation Phase scar Reorganizes collagen and gains strength, reaching up to 80 percent
strength of original tissue strength.
20. Wound Dehiscence Partial or complete separation of tissue layers during the healing
process, often occurring 5 to 9 days post-surgery.
21. Wound Evisceration Total separation of tissue layers allowing visceral organs to protrude;
a medical emergency requiring the patient to be laid flat with a
sterile gauze over the area.
22. Fistula An abnormal connection between two internal organs or between
an internal organ and the outside of the body.
