repositioning
-drawsheet or transfer board -position pt at 30 degrees lateral position -HOB at 30 degrees or less -trapeze bar
26
care planning (PRPPP)
-prevent : deterioration -reduce : factors that contribute to pressure and skin breakdown -prevent : infection -promote : healing -prevent : reoccurrence
27
what to do if pt has pressure injury
-document : stage, size, location, exudate, infection, pain and tissue appearance (picture, if needed) -wound care specialists -surgical treatment
28
wound care specialists -general principles
-determine if specific cleansing protocol and which type of dressings are appropriate -clean with normal saline to avoid damaging cells -keep slightly moist to encourage re-epithelialization
29
surgical treatments
-may be necessary -skin grafts, skin flaps, musculoskeletal flaps
30
pt and family teaching
-Teach prevention techniques to patient and caregivers, including early signs of skin breakdown and tissue injury -Continued nutritional support -Pressure ulcer care techniques, wound care at home -Turning Schedule
31
MASD
moisture associated skin damage
32
IAD
incontinence associated dermatitis
33
MARSI
medical adhesive related skin injury
34
lower extremity ulcers
-different pathophysiology from pressure ulcers -related to changes in blood flow to lower extremities due to chronic disease processes
35
PAD ___(full name)_________ causes problems with ________ in arteries, becoming ________ or ________, usually caused by atherosclerosis
peripheral artery diseases blood flow narrow blocked
36
ulcers caused by ________ and nutrition ________ as a result of ________ circulation

41
must revascularize arterial ulcers with ______ to treat ________, then topical treatment will help with _________ ulcer
stents ischemia healing
42
venous leg ulcers happen when
venous insufficiency occurs when blood flow cannot flow toward from veins in the legs
43
chronic venous insufficiency occurs when
valves are damaged, allowing blood to leak backward, resulting in venous stasis

venous leg ulcers are found where?
Lower legs
47
are venous leg ulcers painful?
painless to moderately painful
48
surrounding skin of venous leg ulcers
red, scaly, weepy, thin
49
_________ therapy promotes blood return and prevents blood from pooling
compression
50
diabetic ulcers are caused by

diabetic ulcers can be found
plantar aspect of foot, over metatarsal heads, under heels and on toes
52
diabetic ulcer wound margins
even, rounded or oblong shape with surrounding callus
53
are diabetic ulcers painful?
painless
54
diabetic ulcers can easily turn into
cellulitis or osteomyelitis
55
treatment of diabetic ulcers
removing stress/pressure from injured site, debriding wound, antibiotics if infection occurs
56
cellulitis
-inflammation of subq tissue -often following break in skin -staph and strep most often cause of infection
57
treatment of cellulitis
-Moist heat, immobilization, elevation -Systemic antibiotic therapy -Hospitalization if IV therapy warranted (severe infections) -Progression to gangrene if left untreated
58
treatment of skin and wound infections
-Cephalosporins -Some penicillins (narrow-spectrum pcn) -Carbapenems -Vancomycin -Clindamycin -Linezolid -Daptomycin -Levofloxacin
59
antibiotic resistance
emergence of resistance to antibiotics is a major concern
60
bacteria acquire resistance through ____________, where DNA coding for drug resistance is transferred from one bacterium to another
conjugation
61
antibiotics do _____ cause ________ changes, but they promote __________ or drug-resistant organisms by creating selection pressures that favor them
not genetic emergence
62
________ - __________ antibiotics promote ______ resistance than _________-________ antibiotics
broad spectrum narrow spectrum
63
psoriasis
common, chronic autoimmune inflammatory disorder characterized by plaque formation with varying degrees of severity
64
mild psoriasis
red patches covered with silver scales on scalp, elbows, knees, palms and soles
65
severe psoriasis
may involve entire skin surface and mucous membranes, superficial pustules, high fever, leukocytosis, painful fissuring of the skin
66
two processes of psoriasis
-accelerated maturation of epidermal cells -excessive activity of inflammatory cells
67
treatments of psoriasis
-topical (glucocorticoids, vitamin D3 analogs, tars) -systemic (methotrexate, biologic agents) -safe sun exposure -phototherapy -photochemotherapy (PUVA therapy)
68
avoid these psoriasis treatments
-scrubbing -long exposure to water -trying to remove scales
69
#1 sign of psoriasis
silver scales of skin
