Skin color vs. skin pigmentation
|
-skin color: consistent with genetic background
-pigmentation: color of the person's skin |
|
Equipment needed for exam
|
strong direct lighting, small centimeter ruler, penlight, gloves
|
|
Inspect the skin. Abnormal color changes.
-pallor -erythemia -cyanosis -jaundice -mottling |
-pallor: paleness (vasoconstriction)
-erythemia: bright, dark, red (vasodilation) -cyanosis: bluish, mottled, usually around the mouth first, lower perfusion, sigh of heart failure/shock -jaundice: yellowish, occurs in the hard/soft palate of mouth first -mottling: patchwork of grey/blue on skin, occurs towards death, usually in the extremities first -hypo-hyperpigmentation: hypo: white, less pigmentation hyper: more pigmentation, freckles |
|
Palpate the skin. Grading for edema.
1+ 2+ 3+ 4+ |
1+ slight indentation, 2mm, normal contours, associated with interstitial fluid volume 30% above normal
2+ deeper pit after pressing, 4mm, lasts longer than 1+, fairly normal contour 3+ deep pit, 6mm, remains several seconds after pressing, skin swelling obvious by general inspection 4+ deep pit, 8mm, remains for a prolonged time after pressing, possible minutes, Frank swelling |
|
Brawny edema
|
fluid can no longer be displaced secondary to excessive interstitial fluid-membrane, no pitting, tissue palpates as firm or hard, skin surface shiny, warm, moist
|
|
Lesions
-confluent -discrete -annular -grouped -gyrated -target -linear -polycylic -zosteriform |
-confluent: lesions run together
-discrete: individual, remain separate -annular: only 1, circular, develop at center and spread out -grouped: clusters that don't run together -gyrated: snake like -target: target in the middle and spread out -linear: straight line -polycylic: annular lesions group together -zosteriform: linear arrangement of lesions that run along a nerve path |
|
Primary lesions:
|
primary lesions: from trauma, lesion that wasn't there before, on previously unaltered skin
|
|
Primary lesions
-macule -papule -mongolian spot, freckle, cafe au lait spot -nodule -wheal -vesicle -cyst -pustule |
-macule: <1cm, flat, hypopigmentation, freckle, small, patch=a lot of macules that run together
-papule: elevated, sharply circumscribed, <1 cm, pink/tan, mole, colored -mongolian spot, freckly, cafe au lait spot -nodule: solid, elevated, hard or soft, extends into dermis, benign or malignant -wheal: superficial, raised, mosquito bit, red, slightly irregular shape, itchy -vesicle: thin wall, bulging, <1cm, sharply defined, clear free fluid that comes out, seen in groups like Herpes (>1 cm=bulla) -cyst: encapsulated, goes into dermis, shiny skin, dermal involvement -pustule: puss-filled, doesn't go deep in dermis, elevated, pimple, circumscribed |
|
Secondary lesions:
|
lesions that change over time due to an outlying factor (scar)
|
|
Secondary lesions
-crust -scale -fissure -erosion -ulcer -excoriation -scar -atrophic scar -keloid -lichenification |
-crust: thin or dried out exudates, scabs, color varies (depends on fluid)
-scale: compact, dry/greasy, cradle cap, flakes of skin -fissure: break in surface of skin, linear, extends into dermis, crack in lips, dry -erosion: scooped out shallow depression, heals without a scar -ulcer: irregular in shape, could bleed, will leave a scar, bed sores, deep depression, extends into dermis -excoriation: abrasion from friction, roadrash, no scarring -scar: caused by repair of primary lesion, loss of normal tissue replaced by CT -atrophic scar: depression of skin level with tissue loss, stretch marks (striae), loss of epidermis -keloid: hypertrophic scar, elevated, excessive scar tissue, invasive, extends beyond injury site, smooth, claw-like -lichenification: moss-like, skin thickens over, scaly |
|
Vascular lesions:
|
no blood flow, will not blanch (due to no blood flow), refer to a blood source involvement to a lesion
|
|
Vascular lesions
-petichia -purpura -telanglectasia -strawyberry birth mark -live spots |
-petichiae: small hemorrhage, bleeding from superficial capillaries
-purpura: group of petichiae -telanglectasia: dilation of small vessels and capillaries cause flat, red marks to appear on the skin -strawberry birthmark -liver spots: normal due to aging, no treatment, sun exposure |
|
Stages of ecchymosis
1 2 3 4 5 |
1. bright red
2. bluish purple 3. blue green 4. yellowish 5. starts to disappear( stage happens in 24 hours) |
|
Stages of ulcers
1 2 3 4 |
1. skin isn't broken, red, no blanching, can intervene
2. broken skin, superficial skin loss, damage to epidermis, dermis involvement (aka erosion) 3. epidermis, dermis, subcutaneous tissue involved, skin scooped out, middle will be black and crater like 4. starting to see bone and CT, crater, other damage you can't see, tunneling-->damage under healthy skin (remember: black tissue (dead)=necrotic) |
|
Danger signs of lesions
ABCDE |
A-asymmetry
B-border irregularity C-color variation D-diameter, .6mm E-elevation and enlargement |
|
Turgor:
|
ability of skin to go back down after pinching (no tenting=good. tenting could indicate dehydration)
|
|
Mobility:
|
ability of skin to rise when pinched (pinch above clavicle)
|
|
Braden scale
|
Looks at skin integrity, higher number=more at risk for skin breakdown. skin assessment. looks at change of skin breakdown
|
|
Inspect and palpate the hair and scalp
-hirutism -vellus -alopecia -gray hair |
-hirsutism: increased body hair on females (indicates endocrine disorder)
-vellus: helps with body temp regulation (found in newborns, anorexia) -alopecia: hair loss, baldness -gray hair: caused by decrese in melanin production in follicles |
|
Inspect and palpate the nails of fingers and toes
-clubbing |
-clubbing significance: could indicate a respiratory disorder. clubbing angle=180' or greater. normal angle=160'
