Wk 5: neurosensory/ integumentary Flashcards
layers of the skin
epidermis (outside layer)
dermis (middle layer)
what is the largest organ in the body?
the skin
the dermis and epidermis are separated by what?
the dermal/epidermal junction
dermis
middle layer
provides strength and support for epidermis
protects layers underneath muscle, blood vessels and bones
epidermis
top outer layer
-basal layer=divides and proliferates, helping top cells slough off and die
primary purpose of skin
protection and sensory perception
integumentary assessment
-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)
pallor
pale, loss of color
in black skin tone can become grey
-look at palm of hands, lips or mucus membranes for people with darker skin
pitting edema
1+
2+
3+
4+
1+: 2mm depression, barley detectable, immediate rebound
2+: 4mm deep, few seconds to rebound
3+: 6mm deep, 10-12 seconds to rebound
4+: 8mm, very deep pitting, >20 seconds o rebound
hard, non-pitting edema is usually related to what?
an injury
pitting edema is d/t what
fluid issues/ overload
indications of pallor
anemia, shock, lack of blood flow
cyanosis
bluish discoloration
in darker skin tones pt can turn yellow-brown or grey
-check nail beds, lips, mucosa
indications of cyanosis
hypoxia, impaired venous return
Jaundice
characteristics/indications
yellow discoloration
look at sclera, mucus membranes
indicates liver dysfunction (RBC distruction)
-can look at palms of hands
erythema
redness
-in darker sin tones palpate skin as well to look for warmth and texture changes
-looks at face, skin pressure prone areas
indications for erythema
inflammation, vasodilation, sun exposure, elevated body temperature
risk factors for impaired skin integrity
impaired sensory perception
impaired mobility
ALOC
shearing
friction
moisture
shearing of skin
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)
friction
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
how does moisture affect skin integrity?
it softens your skin making it more susceptible to damage
what kind of patients are at risk for impaired skin integrity
- older adults with trauma
- spinal cord injuries
- nutritional deficits
- those in long term homes
- Acutely ill
- hospice
- DM
- ICU pt / critical care Pt
- incontinence
what areas are most prone to pressure ulcers
back of head, upper back/shoulders, elbows, inner knees, coccyx, heels
other considerations: pts with nasal cannulas on (inside nostrils/behind ears)
tissue ischemia
pressure applied over a capillary that exceeds normal capillary pressure
three major factors involved in pressure injury development
- pressure intensity
- pressure duration
- tissue tolerance (depends on low blood pressure, poor nutrition, aging, hydration)
deep tissue injury
persistent non-blanchable deep red/maroon/purple discoloration
cannot tell what layers are involved
blanchable vs non-blanchable
blanchable: skin turns red when pressure is relieved
non-blanchable: redness does not occur
unstageable injury
obscured by infection or dying skin (sloughing/eschar), cannot determine involvement
different types of MASD (moisture associated skin damage)
- incontinence associated dermatitis
- intertriginous dermatitis (moist skin rubbing against each other, monitor groin/axillary area)
- periwound moisture associated skin damage
- peristomal moisture associated skin damage
acute wound
-normal timely repair
-return to normal function/anatomical integrity
Ex: trauma/surgical incision
chronic wound
-wound fails to heal normally
-does not return to normal function/anatomical integrity
Ex: pressure ulcer, wound d/t vascular insufficiency
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
what labs do you need to looks at for the nutritional status of a patient?
albumin
pr-albumin
what kind of patients are at risk for poor tissue perfusion, leading to poor wound healing?
diabetics
PVD pt
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.
what does a low braden risk assessment scale indicate?
low score= higher risk for skin impairment
integumentary interventions
nutrition
incontinence/moisture management
positioning /mobilization
pressure prevention pads
Z-flow pillow
heel protectors
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)
three key components of wound management
- assessment
- cleansing
- protection
wound assessment
-appearance: red/yellow/black
-length/width/depth
sinus tracts, tunnels, redness/swelling
-closed wounds: skin edges should be well approximated (staples/ sutures/adhesives)
-drains/tubes present
-pain around incision
how to measure wounds
centimeters, chart in respect to a clock
first measure: head to toe
second: side to side
third: depth
note tunneling/undermining
what to document for wound drainage
amount of drainage
odor
consistency
color
integrity of surrounding skin
for accurate measurement, weight the dressing
1 g = __mL
1 mL
*or just state:s cant, moderate, large, copious amt of drainage
exudate color
serous drainage: watery clear
sanguineous: serum w/ red blood cells, thick/appears reddish
serosanguinous: serum an blood, watery, looks pale/pink
purulent: result of infection. WBC/tissue debris/bacteria. can be yellow, tan, green or brown
nursing interventions for patients with wounds
-hydration and nutrition (2.5 L fluid a day, protein, carbs, vitamins)
-monitor albumin/ pre-albumin
-wound cleansing
-remove sutures/staples
-administer pain meds
-give Abx
-monitor for effectiveness
-document descriptively and thoroughly
non-adherent wound dressing
to not breakdown skin integrity
