keloid development is some individuals
Pressure Ulcer Scale for Healing
National Pressure Ulcer Advisory Panel
measures length, depth, width, and amount of drainage, and tissue type.

serum from the serous membrane of the body
purulent exudate consists of?

consists of pus and blood

seen often is new wound that is infected
serosanguineous drainage consists of ?
clear and blood tinged drainage

seen in surgical incisions

erosion of a blood vessel
Signs of an internal hemorrhage ?
distention of the area
possible sanguineous drainage from the surgical drain
After surgery, the risk of a hemorrhage is greatest ?
first 48 hours
What are the nurses action when a client is hemorrhaging?
apply pressure dressings to the area
monitor vital signs
call the physician
Severe infection causes?
elevated white blood cell count
When is surgical infection most likely to occur?
2 to 11 days postoperatively
partial or total rupturing of a sutured wound.

usually involves an abdominal wound
evisceration. when does it occur? what clients are at risk?
protrusion of the internal viscera through an incision
likely to occur 4 to 5 days post-op
obesity, poor nutrition, multiple trauma, failure of suturing, coughing, vomiting, and dehydration increase the risk
What should the nurse do in the event the client states " something has given away" ?
apply sterile dressing
place client in bed with knees bent
notify surgeon
Pressure points with the client in a supine position?
heels ( calcaneus)
back of the head
Pressure points if the client is in a side lying position?
knee=medial & lateral condyle
greater trochanter
side of the head
Pressure points with the client in the prone position?
genitalia (men)
breast (women)
cheeks and ears
Pressure points with the client is a Fowler's position?
What are the nutritional needs of a client who has a wound that is healing?
rich in+ Protein
vitamins A & C
iron, zinc, and copper
Areas most likely to have problems with skin break down?
skin folds ex:under the breast
areas that are frequently moist=perineum
areas that receive extensive pressure ex:trochanter and coccyx
Assessing common pressure sites
1.natural or fluorescent light
2. a room that is not too cold or hot
3.inspect for whitish or reddened area
4. inspect for areas of abrasions or excoriations
5. palpate surface temperature
6. palpate over bony prominence and areas of edema
yellow wounds=liquid to semi-liquid slough may be accompanied by purulent drainage.
remove nonviable tissue
apply wet to dry dressing
irrigating the wound
using absorbent dressing material= impregnated nonadherent, hydrogel dressing, or exudate absorber
consult DR. about the use of an antimicrobial gel.
red wounds= late regenerative phase
protect to avoid disturbance
1. gently cleansing w/o pressure
2. avoid dry gauze or wet-to dry dressings
3. apply a antimicrobial agent
4. apply gauze or transparent film, or hydrocolloid dressing
5. change infrequently
black wounds= covered with thick nerotic tissue aka eschar
require debridement
when eschar is removed the wound is treated as a yellow wound then a red wound
How does a nurse treat a wound if more than one color is present?

provide range of motion exercises
What are some special considerations that require caution when using heat and cold applications?
Neurosensory impairment
Impaired mental status
Impaired circulation
Immediately after injury or surgery
open wounds
Would cold therapy be used on an open wound?
No because cold decreases blood flow: which will slow down healing
Would heat therapy be affective immediately after surgery?
No. heat increases bleeding.
Would heat or cold therapy be used on a client who has diabetes, peripheral vascular disease, or congestive heart failure?
NO, because they would not have the ability to dissipate heat via blood circulatory system= tissue damage.
