1
Q
Signs of infection
A
- Fever
- Chills
- Excessive thirst
2
Q
Phases of wound healing: Hemostasis
A
- Vessels constrict
- Clotting factors activate
- Clot formation seals
- Platelets release growth factors
3
Q
Phases of wound healing: Inflammatory
A
- Vasodilation causes edema, erythema, and exudate
- Leukocytes arrive to clean up
- Macrophages appear
- Results is a clean wound bed
4
Q
Phases of Wound healing: Proliferative
A
- Epitheliation begins
- Pink granulation tissue is formed
- Angiogenesis
- Collagen is synthesized and begins to strengthen creating structural integrity
- Wound edges approach each other
5
Q
Phases of wound healing: Maturation
A
- Collagen is remodelled
- Well-healed scar
6
Q

A
- Adequate blood prefusion and O2
- Nutrition and hydration

- Pressure off-leading
- Wound infection or increased bioburden
- Advanced age
- Diabetes Mellitus
- Corticosteroid therapy or used of other immunosuppressive agents
- Medical devices
7

A
- Thermoregulation
- Metabolism
- Immunity
