F- WOUND CARE Flashcards
is a break or disruption in the
normal integrity of the skin and tissues. That disruption may range
from a small cut on a finger to a third -degree burn covering almost
all of the body.
wound
wounds made by blunt force that typically does not break the skin but causes considerable tissue damage with bruising and swelling.
CONTUSED WOUNDS
is an open wound that’s caused by the skin rubbing against a rough surface.
Abrasion
is a penetration of the skin and often the underlying tissues by a sharp instrument.
PUNCTURE
wounds—made by an object
that tears tissues producing jagged, irregular edges; examples include glass, jagged wire, and blunt knife.
LACERATED WOUNDS
is a penetration of the skin and the underlying tissues, (e.g., from a bullet or metal fragments) and coming out of the skin.
Penetrating wound
The skin surface is broken, providing a portal of entry for microorganisms. Bleeding, tissue damage, and increased risk for infection and delayed healing may accompany open wounds. Examples include incisions and abrasions.
OPEN WOUND
- results from a blow, force, or strain caused by trauma such as a fall, an assault, or a motor vehicle crash.
- The skin surface is not broken, but soft tissue is damaged, and internal injury and hemorrhage may occur. Examples include ecchymosis and hematomas.
CLOSED WOUND
such as surgical incisions, usually heal within days to weeks. The wound edges are well approximated (edges meet to close skin surface) and the risk of infection is lessened. Usually move through the healing process without difficulty
ACUTE WOUNDS
A chronic wound is one that has failed to progress through the phases of healing in an orderly and timely fashion and has shown no significant progress toward healing in 30 days.
CHRONIC WOUND
DEGREE OF CONTAMINATION: are uninfected wounds in which there is minimal inflammation and the respiratory, gastrointestinal, genital, and urinary tracts are not entered. Primarily closed wounds.
CLEAN WOUNDS
DEGREE OF CONTAMINATION:
are surgical wounds in which
the respiratory, gastrointestinal, genital, or urinary tract has been
entered. Such wounds show
no evidence of infection.
Clean-contaminated wounds
include open, fresh, accidental wounds and surgical wounds involving a major break in sterile technique or a large amount of spillage from the gastrointestinal tract. show evidence of inflammation.
CONTAMINATED WOUND
include wounds containing dead tissue and wounds with evidence of a clinical infection, such as purulent drainage.
Dirty or infected wounds
is material, such as fluid and cells, that has escaped from blood vessels during the inflammatory process and is deposited in tissue or on tissue surfaces.
EXUDATE
give some functions of exudate
- Dilution of toxins produced by bacteria and dying cells
- Transport of leukocytes and plasma proteins, including antibodies, to the site
- Transport of bacterial toxins, dead cells, debris, and other products of inflammation away from the site
is composed primarily of serum, watery in appearance, and has a low protein count.
SEROUS EXUDATE
This type of exudate is seen with mild inflammation resulting in minimal capillary permeability changes and minimal protein molecule escape.
EX. BLISTER FORMATION AFTER A BURN
SEROUS EXUDATE
_______ exudate is also called pus. It generally occurs with severe inflammation accompanied
by infection.
PURULENT
What makes purulent exudate thicker than serous exudate?
- presence of leukocytes, liquefied dead tissue debris, and dead living bacteria.
T OR F: PURULENT EXUDATE may vary in color depending on the causative organism (yellow, green, brown)
consists of large amounts of red blood cells, indicating damage to capillaries that is severe enough to allow the escape of red blood cells from plasma. This type of exudate is frequently seen in open
wounds.
Sanguineous exudate
