MDC 1 Final Exam
1. What is the role of skin?
-protects from invasion of pathogens
-thermoregulates
-keeps fluid/electrolytes balanced
2. What are the 3 layers to the skin?
-subcutaneous tissue (fat)
-dermis
-epidermis
3. What does the subcutaneous tissue do?
-innermost layer, covers muscle and bone
-fat cells make up this layer to help body absorb shock by padding the internal structures
4. What does the dermis do?
-layer above the fat layer/ composed of collagen and elastic fibers
-main purpose is to give skin flexibility/strength
5. What does the epidermis do?
-outermost layer
-acts as first line of defense between the body and environment
6. What are the 2 classifications of the onset of the wound?
-acute: short duration
-chronic: long duration
,7. What is class 1 level of contamination of a surgical wound?
-clean
-describes an uninfected operative would, no inflammation is encountered and the
respiratory, GI, or GU tract.
8. What is class 2 level of contamination of a surgical wound?
-clean/contaminated
-operative wound in which the respiratory, GI, or GU tract is entered under controlled
conditions and w/out unusual contamination
9. What is class 3 level of contamination of a surgical wound?
- contaminated
-open, fresh, accidental wounds, as well as op with major breaks in sterile fields.
-non-purulent inflammation is encountered
10. What is class 4 level of contamination of a surgical wound?
-dirty-infected
-incision created during an operation which viscera are perforated/acute inflammation
with pus is encountered during op.
11. What are the 4 phases of wound healing?
1: homeostasis-clotting
2: inflammatory phase-cleaning
3: proliferative phase- granulation
4: maturation phase-scar
, 12. What is regenerative or epithelial healing of wound healing?
when only the epidermis and part of the dermis are lost, no scar forms (shallow blister
or skin tear)
13. What is first intention of wound healing?
wound edges can connect (well-approximated)
14. What is second intention of wound healing?
wound edges cannot connect need help to heal (ex. extensive tissue loss, infected)
15. What is third intention of wound healing?
delayed healing than later can be closed (delayed primary healing)
16. What is the physical assessment (inspection/palpation) of the integumentary system?
-color, temp and moisture
-assess for localized edema
-decreased perfusion in any areas?
-medications?
-skin clean and dry
-risk for wounds bc of leisure activities?
17. What is serous wound drainage?
clear, watery, typical of clean wounds
18. What is sanguineous wound drainage?
bloody
