Chapter 14 Flashcards
skin
the external membranous covering of the body
epidermis
the external layer of the skin, the majority of which is squamous cells
dermis
the internal layer of the skin: the location of blood vessels, lymph vessels, hair follicles, sweat glands, and sebum
subcutaneous
the layer beneath the dermis’ also known as the hypodermis
pressure ulcer
an open wound or sore caused by pressure, infection, or inflammation
decubitus ulcer
a skin lesion caused by continuous pressure on one spot, particularly on a bony prominence
blister
a bubble or sac formed on the surface of the skin, typically filled with a watery fluid or serum
gangrene
necrotic tissue resulting from a loss of blood supply
phalanges
fingers and toes (singular phalange or phalanx)
hair
a pigmented, cylindrical filament that flows out from the hair follicle within the epidermis
hair follicle
a saclike bulb containing the hair root
cyst
a fluid-filled or gas-filled bubble in the skin
furuncle
a staphylococcal infection in the subcutaneous tissue; commonly know as a boil
papule
a raised lesion with a diameter of less than 5 mm
macule
a flat lesion with a different pigmentation (color) when compared with the surrounding skin
nevus
an abnormally pigmented area of skin. a birthmark is an example
patch
a flat, small area of differently colored or textured skin; a large macule
bulla
a large vesicle that is filled with fluid
pustule
a swollen area of skin’ a vesicle filled with pus
scale
flakey exfoliated epidermis; a flake of skin
ulcer
an erosion or loss of the full thickness of the epidermis
carbuncle
a painful, pus-filled boil due to infection of the epidermis and underlying tissues, often caused by staphylococcus.
When coding a pressure Ulcer what two factors are needed?
anatomical location
depth of the lesion (also known as the sages of ulcer)
What are the five codeable stages?
stage 1 - red skin/irritation
stage 2 - blister
stage 3- pebble has caused a hole that has worn the skin
stage 4- pressure ulcers have become so deep that there is damage to the muscle and bone
unstageable - the lesion may be inaccessible because it is covered by a wound dressing that has not been moved or by a sterile blister or because of some other documented reason
