Integument chap 30 (585-594) Flashcards
The integument includes what parts of the body?
The integument includes skin, hair, and nails.
Pungent body order may be related to what causes?
hyperhidrosis (excessive perspiration), poor hygiene, or bromhidrosis (foul-smelling perspiration)
Inadequate circulating blood or hmg and subsequent reduction in tissue oxygenating may cause the skin to have what coloring
pallor
Where is pallor most evident?
Pallor is most evident in areas with the least pigmentation such as the conjunctiva, oral mucous membrane, nail beds, palms of hands, and soles of feet
Pts w/dark skin may have pallor…
characterized by the absence of underlying red tones in the skin most readily seen in the buccal mucosa
Pts w/brown skin may have pallor…
characterized as a yellowish brown tinge
Pts w/black-skinned may have pallor…
characterized as ashen grey skin
Cyanosis, a bluish-tinge is most evidenced where on the body:
Nail beds, lips, and buccal mucosa (dark-skinned pts may show it in the lining of the eyelids, palms, and soles of their feet) is called:
jaundice (some dark-skinned pts may have a normal yellow tinge to their sclera) is a yellowish tinge first evident where in the body:
Sclera of the eyes and then the mucous membranes of the skin (also assess the the posterior part of the hard palate for yellow coloring).
Skin redness associated w/rashes or other conditions is called:
erythema
A birthmark is defined as what type of pigmentation?
hyperpigmenation
Vitiligo is defined as what type of pigmentation?
Vitiligo are patches of hypopigmentation caused by the distruction of melanocytes of the area
The presence of excess interstitial fluid that may appear swollen, shiny, and taut and tends to blanch the skin color or reddened if inflammation is present is called:
edema
Impaired venous circulation and in some cases reflects cardiac dysfunction or venous abnormalities can be seen as what type of edema?
generalized edema
A skin lesion that appears initially in response to some change in the external/internal environment is called?
primary skin lesion
A skin lesion that does not appear initially but result from chronicity, trauma, or infection of a skin lesion is called:
secondary skin lesion
A primary skin lesion that’s flat, unelevated change in color from 1mm-1cm (freckles, measles, flat moles, vitiligo, rubella) is called:
macule/patch
A primary skin lesion that’s circumscribed, solid elevation of skin less than 1cm (warts, acne, pimples, elevated moles) are called:
papules
A primary skin lesion that’s larger than 1cm (psoriasis, rubeola) is called
plaque
A primary skin lesion that has a circumscribed border, elevated, solid hard mass that extends deeper into the dermis, and are 0.5-2cm (squamous cell carcinoma, fibroma) is called:
Nodule
A primary skin lesion that has an irregular border, elevated, solid, hard mass that extends deeper into the dermis and can be larger than 2cm (malignant melanoma, hemangioma) is called:
tumor
A primary skin lesion that’s a vesicle or bulla filled w/pus (acne vulgaris, impetigo, chronic pustular psoriasis) is called?
pustule
A primary skin lesion that’s circumscribed, round or oval, thin translucent mass filled w/serous fluid or blood, and less than 0.5 cm (herpes simplex, early chic pox, small burn blister) is called:
vesicles
A primary skin lesion that’s circumscribed, round or oval, thin translucent mass filled w/serous fluid or blood, and that are larger than 0.5 cm (large blisters, herpes simplex, 2nd degree burns) is called:
Bullae
A primary skin lesion that’s elevated, encapsulated, fluid-filled or semisolid mass arising from subcutaneous tissue or dermis, and can be 1cm or larger (chalazion of the eyelid) is called:
cyst
A primary skin lesion that’s reddened, localized collection of edema fluid, irregular in shape, and size varies (hives, mosquito bites) is called?
Wheal
A secondary skin lesion that’s translucent, paper-like, sometimes wrinkled skin surface resulting from thinning or wasting away of the ski due to collagen/elastin loss (striae, aged skin) is called:
atrophy
A secondary skin lesion that’s wearing away of the superficial epidermis causing a moist, shallow depression that heals w/o scarring (due to no extending into the dermis; scratch marks, ruptured vesicles) is called:
erosion
A secondary skin lesion that’s rough, thickened, hardened area of epidermis resulting from chronic irritation such as scrating or rubbing (chronic dermatitis) is called:
lichenification
