ch 13 - skin care Flashcards
functions of the skin (7)
- protect underlying structures
- regulate body temp
- sensory input
- stores fat
- metabolism of fat and water
- gas exchange
- production of vit d
skin changes related to aging: epidermis (5)
- decreased melanocytes (lightened skin, decreased protection against sun)
- keratinocytes smaller (slowed wound healing)
- enlarged pigmented spots
- “liver spots”
- dermatosis papulosa nigra
skin changes related to aging: dermis (5)
- 20% thickness loss (tears/bruising more likely)
- dermal blood vessels decrease (pallor, cooler temp, increased susceptibility to skin cancer)
- decreased collagen synthesis (tears more easily)
- thickened and fragmented elastin fibers (“saggy” appearance)
- decreased sebum production (dryer skin)
skin changes related to aging: hypodermis (4)
- loss of subq fat tissue (higher risk injury)
- reduced efficiency of eccrine glands (temp regulation compromised)
- fewer meissners/pacinian corpuscles (diminished tactile sensitivity, higher risk injury)
- decreased langerhans cells (reduced skin immune response)
skin changes related to aging: hair (1)
- diminished melanocytes, loss of hair
- other
skin changes related to aging: nails (1)
-decreased circulation (brittle)
common skin conditions (8)
- xerosis
- pruritis
- scabies
- purpura
- skin tears
- keratosis
- herpes zoster
- candidiasis
-Extremely dry, cracked, and itchy skin
-Most common skin problem associated with
aging
xerosis
cause of xerosis
decreased epidermal filaggrin
where is xerosis most commonly seen
extremities
interventions for xerosis (7)
- maintain 60% humidity environment
- adequate fluid intake
- apply lotions to damp skin after bath
- mineral oil or vaseline is more effective than lotion
- tepid water for bathing, avoid long baths
- use super fatted soaps or skin cleansers
- can use petroleum jelly to affected areas before bed
Itchy skin (not a disease, but a symptom)
pruritis
what can aggravate pruritis (8)
- perfumed detergents
- fabric softeners
- heat
- sweating
- restrictive clothing
- fatigue
- exercise
- meds
3 examples of disease that can cause pruritis
- chronic renal failure
- biliary disease
- hepatic disease
-Causes intense itching • Caused by tiny mites • Contagious, easily transmitted through close physical contact; intimate or casual
scabies
3 objects that can transmit scabies
- clothing
- linen
- furniture
way to diagnose scabies
skin scraping
Tx scabies (3)
- prescribed lotion and creams
- wash clothes and linens in hot soapy water and dry with high heat
- clean and vacuum rooms
Fragility of dermal capillaries secondary to dermal
thinning causing blood vessels to rupture; extravasation of blood into surrounding tissues
purpura
where is purpura commonly seen
dorsal forearm
hands
who is more susceptible to developing purpura
pts taking blood thinners
how to decrease risk for developing purpura (2)
- pressure injury prevention
- fall prevention strategies
- Occurs because skin is thin and fragile
- Painful, acute, accidental in nature
skin tears
how are skin tears categorized
payne-martin classification system
management of skin tears (6)
- proper assessment
- control of bleeding
- cleanse with nontoxic solution
- appropriate dressing
- management of exudate
- prevention of infection
high risk pts for skin tears (7)
- old age
- fragile skin
- h/o skin tears/falls
- impaired activity
- impaired mobility
- impaired sensation
- impaired cognition
prevention tips for skin tears
- wear long sleeves/pants
- ensure adequate hydration and nutrition
- moisturize 2x daily
- careful transfers
- pad bed rails, wheelchairs arms, leg supports
- avoid adhesive products
- tepid water for bathing, soapless bathing products
- caregivers keep nails short and minimal jewelry
- fall preventions
-Benign growth
-Mainly see on trunk, face,
scalp, and neck
-Waxy, raised, stuck-on
appearance
-Flesh colored or
pigmented, various sizes
seborrheic keratosis
-Precancerous
-Related to exposure to
UV light
-Rough scaly sandpaper
patches
-Pink to reddish brown
with erythematous base
actinic keratosis
2 risk factors actinic keratosis
- increased age
- fair complexion
• a benign epidermal growth that presents as hyperpigmented or skin- colored papules • develop on the face and neck beginning in adolescence. -most commonly affects people of african/asian descent
dermatosis papulosa nigra
