- Factors affecting skin integrity
Answer Developmental Level
- infants - baby "dewey"
- Older adults - "drier" Circulation
- Mobility/Activity Level
- Nutrition/Hydration State of Health
- Physical Status Medical Interventions
- What results in skin aging?
Answer sun radiation, tobacco, temperature, nutrition, stress, lack of sleep, pollution
- Hemostasis phase
Answer first stage in wound healing that occurs immediately after injury
- blood vessels constrict
- clotting
- redness and increased heat
- Inflammation phase
Answer 4-6 days; phagocytosis and WBC, generalized body response to hemostasis, growth factor released-acute inflammation (pain, heat, red- ness, swelling)
- vessels dilate & capillary permeability increases
- Proliferation phase
Answer lasts several weeks; 1 / 2
granulation tissue develops to fill in wounds; fibroblastic, regenerative, connective tissue
- capillaries grow across wound
- new blood cell formation
- oxygen and nutrients needed to heal
- Maturation phase
Answer Long term - 6 weeks; can last months of years; collagen remodeled;
blood vessels compressed
- scar
After 3 months, 80-80% of tensile strength is regained.
- Types of wound healing
- Primary intention
Answer primary intention secondary intention tertiary intention
Answer wound edges well-approximated
- Secondary intention
- Tertiary intention
Answer wound edges not well approximated; heals by granulation tissue formation wound=jagged
