Question | Answer |
---|---|
__ is the largest organ of the body, weighing about 40 pounds in the adults. The unbroken skin is considered the body's first defense against bacterial invasion. | Skin |
The active__include interpreting environmental temperature,helping to regulate body temperature, and functioning as an organ of excretion and secretion. | Function of skin |
What is the wound healing process? | wounds can heal by primary intention or secondary intention. |
In__ there is little or no tissue loss, such as clean surgical incision. The skin edges approximate,or close together, and the risk of infection developing is slight | Primary Intention |
_Is a would involving loss of tissue such as a severe laceration or chronic wound such as a pressure ulcer. The edges do not close, increasing the risk for infection and loss of tissue function. Potter and Perry pg.1062 | Secondary Intention |
With_, the wound is usually left open and allowed to heal by granulation. Tissue defects are filled with fragile granulation tissue(connective tissue with more abundant blood supply than collagen.) | Secondary Intention |
During___Scarring is usually extensive with the prolonged healing. | Secondary Intention |
Wounds that heal by primary intention and shallow wounds that only involve loss of the epidermis and perhaps some of the dermis are repaired by the resurfacing of the wound with new epidermal cells is called what? | Partial-Thickness Wound Repair |

_____is a collection of clotted blood, is a localized collection of blood underneath the tissues. It appears as a bluish swelling or mass. External bleeding will be more obvious. The dressings are saturated. | Hematoma |
_____ ______ are draining bright red blood. Observe closely particularly surgical wounds in the first 24 to 48 hours. | Surgical drains |
____ wound infection inhibits healing by increasing tissue damage and altering the healing process. Chances are greater when dead or necrotic tissue is present, foreign bodies are in or near the wound, and the blood supply and local tissue defense is redu | bacterial |
On a contaminated or traumatic wound, infection would usually occur in ___days. With a surgical wound the infection will occur in about 4-5 days. When an infection is present,a culture is usually taken of the exudate. | 2-3 |
The __ __ will appear tense,swollen,and painful, with redness extending beyond the immediate wound edge. | wound edges |
When dealing with infections, exudate may be nnpurulent(containing pus), yellow green,or brown and odorous depending on the causative organism. Systemic signs include_,_,_,_ | fever,general malaise, and elevated wbc count |
__is the partial or total separation of layers of skin and tissue above the fascia in a wound that is not healing properly.__ clients have a high risk of _ because of constant strain on their wounds and the poor vascularity of fatty tissue. | Dehiscence, obese, dihiscence |
Dehiscence occurs most often in __ __ __ after a sudden strain such as coughing,vomiting, or sitting up in bed. When Serosanguineous drainage increases from a wound, be alert for dihiscence. | abdominal surgical wounds |
__ occurs when the wound layers separate below the fascial layer, and ___may protrude through the wound opening. | Evisceration, visceral organs |
If evisceration occurs. It is a medical emergency requiring placement of sterile towels soaked in sterile ___ over the extruding tissues to reduce chances of bacterial invasion and drying before surgical repair occurs | saline |
__ is an abnormal opening between two organs or between an organ and the outside body.__ can result from wound-healing problems associated with trauma, infection,radiation exposure,or disease such as cancer | Fistula |
