A
the skin
3
Q
the dermis and epidermis are separated by what?
A
the dermal/epidermal junction
4
Q
dermis
A
middle layer
provides strength and support for epidermis
protects layers underneath muscle, blood vessels and bones
5
Q
epidermis
A
top outer layer
-basal layer=divides and proliferates, helping top cells slough off and die
6
Q
primary purpose of skin
A
protection and sensory perception
7
Q
integumentary assessment
A
-know norms vs concerning findings
-color (pallor, cyanosis, jaundice)
-moisture (MMM, diaphoresis)
-temperature (warm nml, cold can indicate poor perfusion, warm can indicate infection)
-texture (smooth, rough, tight, supple, thick, thin, indurated, elevated, soft)
-turgor (fluid balance, decreases with age)
-vascularity (color around vascular areas of skin, can be red/pink/pale, veins can be more or less visible, capillaries can be fragile, petechia)
-edema
-lesions (wounds/rashes/ any unusual findings)
8

19
Q
shearing of skin
A
affecting DEEPER levels of skin
sliding movement of skin and SQ tissue when muscle and bone are NOT MOVING
Ex: head of bed is elevated, patient slides down in bed, skin is stuck to where it was but underlying tissues move
-affects underlying tissue capillaries (stretched/damaged, leading to ischemia)
20
Q
friction
A
affecting OUTER layer of skin
two surfaces moving across one another
Ex: pulling a patient up in bed w/o draw sheet, or patient moves against draw sheet
21
Q
how does moisture affect skin integrity?
A
it softens your skin making it more susceptible to damage
22
Q
what kind of patients are at risk for impaired skin integrity
A
- older adults with trauma
- spinal cord injuries
- nutritional deficits
- those in long term homes
- Acutely ill
- hospice
- DM
- ICU pt / critical care Pt
- incontinence
23
Q
what areas are most prone to pressure ulcers
A
back of head, upper back/shoulders, elbows, inner knees, coccyx, heels
other considerations: pts with nasal cannulas on (inside nostrils/behind ears)
24
Q
tissue ischemia
A
pressure applied over a capillary that exceeds normal capillary pressure
25
three major factors involved in pressure injury development
1. pressure intensity
2. pressure duration
3. tissue tolerance (depends on low blood pressure, poor nutrition, aging, hydration)
26
deep tissue injury
persistent non-blanchable deep red/maroon/purple discoloration
**cannot tell what layers are involved**
27
blanchable vs non-blanchable
blanchable: skin turns red when pressure is relieved
non-blanchable: redness does not occur
28
unstageable injury
obscured by infection or dying skin (sloughing/eschar), cannot determine involvement
29
different types of MASD (moisture associated skin damage)
1. incontinence associated dermatitis
2. intertriginous dermatitis (moist skin rubbing against each other, monitor groin/axillary area)
3. periwound moisture associated skin damage
4. peristomal moisture associated skin damage
30
acute wound
-normal timely repair
-return to normal function/anatomical integrity
Ex: trauma/surgical incision
31
chronic wound

-does not return to normal function/anatomical integrity
Ex: pressure ulcer, wound d/t vascular insufficiency
32
what affects skin and wound healing
-nutrition (protein, Vit A/C, zinc, copper critical for healing. along with adequate caloric intake)
-tissue perfusion
-infection
-age/ loss of skin tugor
-loss of collagen
-overall wellness
-decreased WBC
-medications (steroids/ chemo/antiinflamatory)
-low Hgb
-chronic dz
33
what labs do you need to looks at for the nutritional status of a patient?
albumin
pr-albumin
34
what kind of patients are at risk for poor tissue perfusion, leading to poor wound healing?
diabetics
PVD pt
35
Which patient is most likely to experience delayed wound healing?
A. patient with high WBC
B. a 25 y/o male with no pertinent medical history
C. a 30 year old female who takes vitamin supplements everyday
D. A 85 year old male with DM
D. age can lead to slowed healing due to delayed inflammatory responses and delayed collagen synthesis. DM can cause poor perfusion.
36
what does a low braden risk assessment scale indicate?
low score= higher risk for skin impairment
37
integumentary interventions
nutrition
incontinence/moisture management
positioning /mobilization
pressure prevention pads
Z-flow pillow
heel protectors
38
which patient will not have a high chance of impaired wound healing?
A. a patient with PVD
B. a patient that is dehydrated with tenting of the skin
C. a patient with T1 DM
D. a patient admitted for constipation but now has regular GI movements
E. a 95 year old patient with decreased mobility
D. would not have a a higher chance to impaired wound healing, if his GI track was impaired and he was not absorbing nutrients adequately then he could.
rationale:
A. decreased circulation
B. loss of skin turgor / dehydration / decreased nutrients
C. impaired immune function
E. age/ mobility (age also causes decreases collagen)
39
