SKIN, HAIR, AND NAILS Flashcards
- areas of dark, velvety discoloration in body folds and creases
- often affect armpits, groin, and neck
acanthosis nigricans
Pigment cells of the skin, melanocytes, are destroyed in certain areas resulting to loss of skin color in the form of depigmented, or white, patches of skin
vitiligo
increased amount of deoxygenated homoglobin associated with hypoxia
cyanosis
reduced amount of oxyhemoglobin
location: face, conjunctiva, nail beds
anemia
reduced visibility of oxyhemoglobin as a result of decreased blood flow
location: skin, nail beds, conjunctiva, lips
shock
congenital or autoimmune condition causing lack of pigment
vitiligo
Hands, fingertips, or feet turn blue because they are not getting enough oxygen rich blood
peripheral cyanosis / acrocyanosis
Generalized bluish discoloration of the body and the visible mucous membranes, which occurs due to inadequate oxygenation secondary to conditions that lead to an increase in deoxygenated hemoglobin or presence of abnormal hemoglobin
central cyanosis
Triad of redness, warmth, and burning pain, most notably affecting the extremities
erythromelalgia
Causes the blood vessels in the extremities to narrow, restricting blood flow
raynaud’s phenomenon
- yellow-orange skin color
- increased deposition of bilirubin in the tissues
jaundice
- redness of skin
- increased viability of oxyhemoglobin as a result of dilation or increased blood flow
erythema
- black and blue skin color
- extravasation of blood into the subcutaneous tissue
ecchymosis
Classically seen with hyperpigmentation due to adrenocorticotropic hormone melanogenesis
addison’s disease
Inherited condition that affects the production of melanin, the pigment that colors the skin, hair and eyes
albinism
persisted scaly plaques on the scalp, face, ears which subsequently can progress to scarring, atrophy, dyspigmentation, and permanent hair loss in affected hair-bearing areas
discoid lupus erythematosus
true or false: inspecting skin on limbs, under breasts, and in groin area are commonly done for obese clients
true
- persistent nonblanchable erythema of intact skin
- In darker skin tones, may appear with persistent red, blue, or purple tones
- Most common of all pressure ulcers. “At risk” person
stage 1 ulcer
- partial-thickness skin loss involving epidermis, dermis, or both
- is superficial and presents as an erosion, blister, or vesicle
stage 2 ulcer
full-thickness skin loss involving damage or necrosis of subcutaneous tissue that may extend down to, but not through underlying fascia
stage 3 ulcer
- full-thickness skin loss with extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structure
- undermining and sinus tracts may also be present
stage 4 ulcer
- original lesions from previously normal skin
- directly associated with a disease process
- rarely specific to a single disease
primary
- originated from primary skin lesions
- may be initiated by external forces (scratching or infection) or the healing process
secondary
lesions associated with bleeding, aging, circulatory conditions, diabetes, preganancy, and heptaic diseases
vascular
a circumsized, flat lesions that differs from surrounding skin because of its color
