Definition
A. Epidermis
1. Stratum Corneum
2. Stratum Basale

Definition
1. constant movement of cells
2. desquamation
3. protection

Definition
1. Protect
2. Support
Term
What are functions of the dermis in injured skin?
Definition
to restore

2. lacerations
3. contusion
4. puncture
5. penetrating
6. avulsion
Term
What are the types burn wounds?

Term
What are acute wounds and what are its characteristics?
Definition
wounds that progress through the normal sequence of repair
Characteristics: wounds edges well approximated, decreased risk of infection
Term
What are chronic wounds and what are the characteristics?
Definition
wounds that do not progress through the normal sequence of repair (anything that last longer than 6 weeks)
Characteristics: wound edges often not approximated, increased risk of infection, delayed healing process
Term
healing process includes...
Definition
primary
secondary
tertiary
Term
what are intentional wounds and what are the characteristics?
Definition
results of planned invasive therapy or treatment
characteristics: clean wound edges, bleeding controlled, low risk for infection, wound healing is facilitated
Term
what are unintentional wounds and what are the characteristics?
Definition
occur from unexpected trauma
characteristics:
wound edges are usually jagged, multiple trauma is common, bleeding is uncontrolled, high risk for infection, and prolonged healing time
Term
what are open wounds and what are the characteristics?
Definition
the surface of the skin is broken
characteristics
potential tissue damage, increased risk of infection, risk for bleeding, risk for delayed wound healing
Term
what are closed wounds and what are the characteristics?
Definition
skin is not broken (blunt trauma, spring, pressure ulcer)
characteristics:
low risk of infection
Term
What is primary wound care healing and what are the characteristics?
Definition
occurs in wounds with minimal tissue loss
characteristics:
wound edges well approximated, wound edges seal together rapidly, decreased risk for scarring, decreased risk for infection
Term
What is secondary wound healing and what are the characteristics?
Definition
healing occurs with tissue loss (actual tissue loss)
characteristics:
wound edges not approximated, openings fill with granulation tissue, later, epithelial cells grow over the granulation tissue, increased risk for infection, increased risk for scarring
Term
What is tertiary wound healing and what are the characteristics?
Definition
occurs when there is a delay in the time between injury and the closure of the wound
characteristics:
wound surfaces granulate, scarring is common, high risk for infection
Term
what is partial-thickness healing and what are the characteristics?
Definition
shallow wounds involving loss of the epidermis and possibly partial loss of the dermis
characteristics:
healing occurs by regeneration
Term
what are the components of wound healing in a partial- thickness wound?
Definition
inflammatory response- normal for the 1st 24 hrs, redness, swelling, serious drainage, but only healthy for 1st 24hrs.
epithelial proliferation
reestablishment of epidermis
Term
what is the healing process of partial thickness healing?
Definition
Inflammatory response- redness and swelling, moderate serous exudate, limited to the first 24 hours after injury
epithelial proliferation- redness and swelling
reestablishment of the epidermis- new epithelium is only a few cells thick, cells slowly reestablish normal thickness, new cells appear pink dry tissue
