Ch. 6 & 9 Flashcards
Acute Pain
recent onset (less than 6 months), results from tissue damage, is usually self-limiting, and ends when the tissue heals
Persistent (Chronic) Pain
intermittent or continuous, lasting more than 6 months
Nociceptive Pain
results from activation of essentially normal neural systems that produce somatic or visceral pain
Neuropathic Pain
occurs from an abnormal processing of sensory input by the central or peripheral nervous systems
Referred Pain
pain in an area away from the tissue injury or disease
Phantom Pain
pain that feels like it’s coming from a body part that’s no longer there
Pain Threshold
point at which a stimulus is perceived as pain
Pain Tolerance
duration or intensity of pain that a person endures or tolerates before responding outwardly
Tissue Integrity
structural intactness and physiologic function of tissues and conditions that affect integrity
Primary Lesions
expected variations of the skin and include moles, freckles, patches, and comedones (acne) among adolescents and young adults
Secondary Lesions
some are considered expected variations; a scar is a common variation caused by injury to the skin
Vascular Lesions
many are considered common variations; bruising on a bony prominence is generally considered a common finding secondary to the activities of daily living
Ex: petechiae, purpura, ecchymosis, angioma
Petechiae
tiny, flat, reddish-purple, nonblanchable discoloration in skin LESS THAN 0.5 cm in diameter
increased vascular pressure = ruptured capillaries
appears on chest, mouth, nose, cheek
Purpura
flat, reddish-purple, nonblanchable discoloration in skin GREATER THAN 0.5 cm in diameter
Ecchymosis
bruise; reddish-purple, spot of variable size
Angioma
benign tumor consisting of a mass of small blood vessels; can vary in size from very small to large
Pressure Ulcer
localized injury to the skin and/or underlying tissue usually over a bony prominence as a result of pressure or pressure in combination with shear and/or friction
Stage 1 Pressure Ulcer
intact skin with nonblanchable redness, usually over a bony prominence; area may be painful, firm, soft, warmer, or cooler compared to adjacent tissue
Stage 2 Pressure Ulcer
partial-thickness loss of dermis; presents as a shiny or dry shallow open ulcer with pink wound bed without slough or bruising; may also present as an intact or open/ruptured serum-filled blister
Stage 3 Pressure Ulcer
full-thickness skin loss involving damage to or necrosis of subcutaneous tissue; subcutaneous fat may be visible, but bone, tendon, or muscles are NOT exposed; slough may be present; wound may include undermining and tunneling; depth varies by location
Stage 4 Pressure Ulcer
full-thickness tissue loss with exposed bone, tendon, or muscle; slough or eschar may be present within wound bed; undermining and tunneling often present; depth varies on location
Pallor
pale skin color that may appear white
cool/cold
Cyanosis
grayish-blue tone, especially in nail beds, earlobes, lips, mucous membranes, palms, and soles of feet
decreased oxygen
Jaundice
yellowish color of skin, sclera of eyes, fingernails, palms of hands, and oral mucosa
increased bilirubin
Erythema
reddish tone with evidence of increased skin temperature secondary to inflammation
increased inflammation and warmth
Petechiae vs. Purpura
Petechiae: less than 0.5 cm; appear as tiny red spots pinpoint to pin head in size
Purpura: more than 0.5 cm
Both: flat, reddish-purple, nonblanchable spots in skin
Vesical vs. Pustule vs. Bulla
Vesical: elevated, circumscribed, superficial, not into dermis; filled with serous fluid (clear); less than 1 cm
Pustule: elevated, superficial, lesion; filled with purulent fluid (white, yellow, brown)
Bulla: vesicle greater than 1 cm
Macule vs. Papule vs. Patch
Macule: flat, circumscribed area that is a change in color of skin; LESS THAN 1 cm
Papule: elevated, firm, circumscribed area less than 1 cm
Patch: flat, nonpalpable, irregular-shaped macule MORE THAN 1 cm
Finger Clubbing
no space is observed between the fingers and nail beds angle away from one another
base of nail is enlarged and curved
caused by proliferation of connective tissue, resulting in enlargement of distal fingers
Braden Scale
assessment tool for predicting the risk of pressure ulcers
Melanoma (signs of [ABC…])
A - asymmetry (not round or oval)
B - border (poorly defined or irregular border)
C - color (uneven, variegated)
D - diameter (usually greater than 6 mm)
E - evolving (skin lesion that looks different from others or is changing in size, shape or color)
F - feeling (itching, tingling, stinging)
Assessment of Skin Turgor
picking up and slightly pinching the skin on the forearm or under the clavicle; skin should be elastic and return to place immediately when released (less than 3 seconds)
