FINAL EXAM - Integumentary System, Burns, Wounds Flashcards
(262 cards)
Epidermis - Characteristics (10)
- Prevents dehydration2. Protects from microbes3. Keeps nutrients in the skin4. Responds to stimuli5. Keratin6. Reproductive layer of the skin7. Surrounds hair follicles8. Surrounds sweat and sebaceous glands9. thin10 avascular
The dermis contains (9)
- hair follicles2. nerve endings3. lymph vessels4. blood vessels5. collagen6. elastin7. sweat8. sebaceous glands 9. fibroblasts
fibroblasts in the dermis produce
collagen
Fn’s of the dermis (3)
- provides nutrition2. provides protection3. source of blood flow
Phases of wound healing (5)
- hemostasis2. inflammation3. epithelialization4. proliferation5. maturation
Hemostasis
platelets aggregate, clot formation
inflammation - what occurs and what are the clinical signs
phagocytosis, clinical signs are heat, pain, redness
epithelialization
migration of basal cells; need most environment
proliferation
granulation, contraction
maturation
remodeling, scar formation
Primary (First Intention)
wound borders approximate
Secondary
wound borders are not approximated
Delayed Primary (Third Intention)
Sutured after infection is controlled
Subcutaneous tissue - characteristics (3)
- mostly fat and fascia2. blood vessels that support the dermis and epidermis3. provides cushioning and insulation
What must remain intact in order to get wound to granulate?
periosteum
Tendons are _____ _____ when healthy, but have poor ______
shiny whitevascularity
Acute wound
heals in the expected sequence and time frame
Chronic wound
fails to heal as expected, does not proceed through normal phases of healing
Chronic wound characteristics (4)
- repeated trauma2. abnormal blood flow3. large bacterial load4. local tissue ischemia
Etiology of chronic wounds (3)
- PVD2. DM3. physical immobility
Intrinsic factors of delayed wound healing (5)
- age - geriatric2. chronic diseases3. edema4. poor perfusion - lack of blood flow5. immunosuppression
Extrinsic factors of delayed wound healing (6)
- poor nutrition and hydration2. medications3. necrosis4. bioburden5. infection6. incontinence
Iatrogenic factors of delayed wound healing (4)
- inappropriate wound management2. Desiccation (wound pops open)3. Inadequate offloading4. improper handling of dressings
Factors to consider with wound assessment (7)
- wound classification2. new onset vs recurrence3. wound history - time present, prior treatment interventions4. anatomical location5. Wound appearance6. Appearance of periwound7. sensation
