25
epibole
rolled over edge w/ dry skin
26
hyperkeratosis
excess of skin
27
serous, serosanguineous, sanguineous, purulent
serous - clear serosanguineous - mix of blood sanguineous - bloody purulent - pus
28
What is critical colonization? What is required?
bacteria is replicating and antibiotics are required
29
sharp debridement
carefully cut off part of wound Non-selective
30
autolytic debridement
dressing placed on wound and body natural enzymes used - moisture accumulates, old tissue swells up and separates from the wound Selective
31
enzymatic debridement
add certain enzymes to dressing Selective
32
mechanical debridement
dry dressing put on and soaks up wound and then ripped off Non-selective
33
What braces limit spinal flexion and are used for a compression fracture on anterior part of the vertebrae?
Jewett and CASH brace
34
Sterile vs clean technique
sterile - sterile field, equipment, PPE and for high-risk patients clean - clean gloves, clean field and for non-immunocompromised patients
35
What is the Braden scale? Scoring?
- asses wound risk - lower score = more risk (max score 18) Sever risk < or = 9 High risk 10-12 Moderate risk 13-14 Mild risk 15-18
36
repositioning schedules for bed and chair
bed - every 2 hours chair - every 1 hour and weight shifts every 15 min
37
Braden scale 6 risk factors
- sensory perception - moisture - activity level - mobility level - nutrition - friction/shear
38
What is used to assess protein metabolism or nutritional status of a patient?
nitrogen-balance study
39
Physical signs of dehydration (6)
- dry skin - cracked lips - decreased BP - increased pulse rate - constipation - concentrated urine
40
Clinical signs of dehydration (5)
- increased lab values - decreased BP - increased pulse rate - constipation - concentrated urine
41
Pressure ulcer “Dos and Don’ts”
Do – skin checks, proper nutrition, position changes | Don’t – oily soaps/lotions, wrinkled sheets
42
Colonization vs Infection
Colonization – group of organisms living together in body prior to tissue invasion not causing infection Infection – invasion of tissues by microorganisms resulting in systemic reaction
43
3 signs of infection
- local and systemic symptoms - contamination and bacterial balance - clinical abnormalities
44
surface swab culturing
cleansing wound w/o antiseptic solution
45
Needle aspiration
needle into tissue to aspirate fluid that contains organisms
46
Tissue biopsy
removal of tissue w/ scalpel or punch biopsy
47
benefits of a moist wound bed
- communication amongst cells - communication w/ growth factors - construction of collagen - migration of new epithelium
48
steps to the healing process of wound | - What type of wounds is this done for?
injury - hemostasis (stopping of bleeding) - inflammation - proliferation - repair and remodeling - scar maturation Only done for partial or full-thickness wounds
49
What are the barriers to healing in a chronic wound?
- Longer healing time w/ timelines based on wound site, cause of wound, and age/physical condition of patient - Inflammatory process persists and wound immune defense is impaired - Healing process stagnates and may require active wound treatment
50
What are the four primary types of chronic wounds?
- Pressure ulcers - Venous ulcers - Arterial ulcers - Diabetic ulcers
51
Which type of chronic wound occurs from prolonged pressure, usually on a bony prominence?
pressure ulcer
52
Which type of chronic wound has minimal drainage, often occurs on the toes or dorsum of the foot, and is accompanied by a weak or absent pulse?
arterial ulcers
53
Which type of chronic wound most often occurs on the plantar surface of the foot, results from uncontrolled elevated blood glucose, and is a major cause of amputations?
diabetic ulcers
54
Which type has heavy drainage, irregular wound borders, and often results in hemosiderin stains around the lower leg/ankle?
venous ulcers
55
What are the secondary signs of infection? (7)
- Delayed healing - Changes in color of wound bed - Friable (easily crumbled) granulation tissue - Absent or abnormal granulation tissue - Increase or abnormal order - Increased drainage - Increased pain at wound site
56
active vs passive topical dressings
active - aid in changing biological or chemical environment in wound and may also have characteristics of passive dressings passive - cover wound, maintain moisture balance, may protect form outside environment insults via physical barrier
57
Negative Pressure Wound Therapy (NPWT)
- Involves placing a dressing into wound cavity and applying a controlled sub-atmospheric pressure - Removes chronic edema, leading to increased localized blood flow and applied forces result in enhanced formation of granulation tissue
58
What type of wound is contraindicated for negative pressure wound therapy?
ischemic wounds
59
What is the desired wound appearance that indicates the development of granulation tissue?
red and beefy and should increase in size w/ each wound reevaluation
60
what two colors indicate non-viable tissue?
Black/brown or yellow
61
How do you measure ABI and what are ranges?
ankle systolic pressure over the brachial systolic pressure normal: 0.9-1.3 mild: 0.7-0.89 moderate: 0.4-0.69 severe: <0.4 values over 1.3 are non-compressible vessels
62
What are some hallmarks of superficial infections? (7)
- non-healing - bright red granulation tissue - friable and exuberant granulation - new areas of breakdown and necrosis - increased exudate - bridging of soft tissue and the epithelium - foul odor
63
What are some hallmarks of deep wound infections? (10)
- pain - swelling, induration (growing hard/sclerosis) - erythema (>2 cm) - wound breakdown - increased size of satellite areas - undermining or tunneling - probing to bone - flu-like symptoms - anorexia - erratic glucose control
64
What are the most common areas for diabetic ulcers?
- plantar aspect of foot - over metatarsal heads - under heel
65
Which classification system provides percent of risk of foot ulcer and amputation based on medical status?
diabetic foot risk classification
66
Which classification system assesses ulcer depth along with presence of gangrene and loss of perfusion using six grades (0-5); does not fully address infection and ischemia.
Wagner Ulcer Classification
67
Which classification system assesses ulcer depth, presence of infection and presence of signs of LE ischemia using a matrix of four grades combined with four stages?
University of Texas Wound Classification System
68
Which classification system describes presence of infection and ischemia better and may help in predicting the outcome of the diabetic ulcer?
University of Texas Wound Classification System > Wagner Ulcer Classification System
