Q

What is Mechanical Debridement?

A

Techniques such as wet to dry dressings, whirlpool therapy, hydrotherapy

25
What is Enzymatic Debridement?
Use of enzymatic creams to break down necrotic tissue without affecting viable tissue around the wound ## Footnote Enzymatic debridement is a selective method that targets dead tissue.
26
What is Biotherapy (Maggot) Debridement?
Medical grade larvae dissolve dead and infected tissues from wounds by secreting enzymes that break down dead tissue ## Footnote The larvae are changed every 48-72 hours and disposed of in biohazard medical waste bags.
27
How does Biotherapy (Maggot) Debridement ensure healthy tissue remains unharmed?
The enzymes secreted by the larvae are neutralized so healthy tissue remains unharmed ## Footnote This method is effective but can be emotionally disturbing to clients.
28
What is Leech therapy used for?
Wound management requiring frequent changes ## Footnote Leech therapy helps in blood circulation and can assist in healing.
29
What type of dressings should be used around IV catheters and CVCs?
Transparent, occlusive dressings ## Footnote These dressings help protect insertion sites and reduce infection risk.
30
What is Negative Pressure Wound Therapy?
Wound Vac that suctions bacteria and stimulates regeneration ## Footnote This therapy promotes healing by creating a negative pressure environment.
31
What signs indicate a wound is healing?
Less redness, less drainage ## Footnote Monitoring these signs is crucial in wound assessment.
32
What laboratory results should the nurse review to assess antibiotic effectiveness?
Less WBC on labs ## Footnote A decrease in white blood cell count can indicate effective treatment.
33
What labs may the nurse want to review if the patient is on prolonged antibiotic therapy?
Therapeutic levels of antibiotics ## Footnote Monitoring for potential toxicity or side effects is important in prolonged therapy.
34
Younger skin has more what compared to older skin?
more collagen
35
EXAM Factor affecting skin integrity
Protein! helps with wound healing and foundation to repair skin.
36
Protein lowers blood sugar with diabetes
N/A
37
Wounds heal inside to out
38
Secondary Intention
wet to dry dressing
39
What happens during the inflammatory phase?
Clean up, blood vessels dialate, WBC increase
40
Proliferative growth phase
Granulation tissue forms: A new tissue made of collagen and other proteins replaces the provisional fibrin matrix  New blood vessels grow: Capillaries replace damaged vessels to restore circulation  Epithelialization occurs: New skin forms over the wound 
41
Maturation phase
Collagen production: Collagen is remodeled from type III to type I, and the collagen fibers cross-link to reduce scar thickness  Wound contraction: Myofibroblasts, a type of fibroblast, contract to close the wound edges   Apoptosis: Unneeded cells are removed through programmed cell death  Scar tissue: A buildup of collagen in the granulation tissue forms new scar tissue 
42
What is hemorrhage?
hemostasis usually occurs within minutes of injury When are clients most at risk for hemorrhage?Internal Hemorrhage – Swelling, hematoma may be present Why would a hematoma be dangerous?External Hemorrhage
43
What is infection?
What are s/s of infection in a wound? When would the client show s/s of infection after surgery? Fever, redness, drainage, smell, sweat
44
What is dehiscence?
separation of one or more layers of a wound use waist binder, often due to smoking, obesity and lack of nutrition
45
What is evisceration?
EMERGENCY is total separation of layers of the wound. It is a surgical complication. SOAK in sterile solution/ towels to prevent drying out
46
A nurse needs to chart within how many hours of admission for wounds?
24h
47
Slough
white, yellow, tan, stringy or loose, adherent to wound bed - Debride
48
Eschar
necrotic tissue, dry, thick, leathery, black, brown, or gray - Debride
49
What is the Braden scale for wounds? EXAM: example, patient has a score of 5, what intervention?
determine risk for pressure uclers What interventions? -barriers -scuds -protein -dry skin -nutrition -movement
50
Swabbing, tissue biopsy, and needle aspiration can be used to identify pathogens.  An Xray, CT, or MRI may be needed to assess how deep the infection is. Infection involving the bone or muscle may require specialized treatment or amputation.
What are other labs associated with new or chronic wounds? WBC, hemoglobin, lactic acid What is lactic acid? organ failure What does it indicate? septis Would the nurse draw labs or get cultures before or after administering antibiotics? Before
51
Diabetic ulcer vs staged wound
52
Staged vs upstaged wound
53
Wound interventions
swab, clean, send sample of to lab. Apply dressing. call wound nurse stage 2 or more
54
isotonic solution
normal saline
55
What PPE should be worn during irrigation?
face shield
56
Penrose drain
small tube, not structured
57
Jackson pratt drain or called hemovac
placed to suction #1 intervention- remove take off cap, no suction
58
Remove suction when draining
Drains
59
Serous Wound
straw colored
60
Serous- sanguineous Wound
yellow/red
61
Sanguineous Wound
Bloody
62
purulent Wound
pus infection
63
Tissue in wound bed
Slough and Eschar Granulation tissue – Pink to red moist tissue, pebble like – Clean and protect Nongranulating tissue – absence of granulation but pink and shiny – Promote tissue growth, keep clean Epithelial - regenerating epidermis, pink, pearly white – Clean and protect
