PN3006 Final: Questions And Accurate Answers (A+)
Dermal-epidermal junction Right Ans - separates dermis and epidermis
Epidermis Right Ans - Outer layer of skin
Dermis Right Ans - Inner layer of skin
Tidy wound Right Ans - surgical incisions caused by sharp objects. * heal by
primary intention*
Dirty wound Right Ans - Due to crushing, tearing or avulsion, devitalized
tissue, vascular injury, liberal excision or burns Heals by secondary intention
Clean wound Right Ans - non-penetrated blunt trauma
Clean-contaminated wound Right Ans - Similar to a clean wound, but
because the surgery involves organ systems that are likely to contain bacteria,
the risk for infection is greater.
Contaminated wound Right Ans - a wound with bacteria present resulting
from trauma, a break in sterile technique during surgery or spillage of bowel
contents or other bacteria-laden material during surgery
Infected wound Right Ans - a wound containing large amounts of microbes
that shows signs of infection; a dirty wound
Primary intention healing Right Ans - tissue surfaces are approximated
(closed) and there is minimal or no tissue loss, formation of minimal
granulation tissue and scarring (surgical wound)
Secondary intention healing Right Ans - Occurs in a wound that is
extensive, and edges cannot be approximated (burns)
Tertiary wound healing Right Ans - initially healed by secondary and then
primary once edges are approximated
Factors effecting wound healing? Right Ans - age
nutrition
, underlying disease
decreased blood flow and O2 delivery
Immunocompromised
infection or foriegn matter
dehiscence
Phases of wound healing Right Ans - Hemostasis
Inflammatory
Proliferation
Maturation
Hemostasis Right Ans - stoppage of bleeding
Inflammatory healing phase Right Ans - begins with the injury when cells
migrate to site.
Proliferation phase of wound healing Right Ans - -begins on 3rd, 4th day -
lasts 2-3 weeks
-macrophages continue to clear the wound of debris and stimulate fibroblasts
which synthesize collagen
-new capillary networks formed to provide oxygen and nutrients to spport
collagen and for further synthesis of granulation tissue
-tissue is deep pink
-full thickness wound begins to close by contration as new tissue is grown
-scarring influenced by degree of stress on wound
maturation phase Right Ans - the third phase of wound healing, in which
scar tissue forms
serous drainage Right Ans - clear, watery plasma
sanguineous drainage Right Ans - bloody drainage
Serous Sanguineous: Right Ans - Clear and blood tinged
purulent Right Ans - containing pus
Wound drains Right Ans - . Jackson- pratt
hemo vac
