Q

integumentary system

A

the structures of the integumentary system consist of the skin (and its structures and glands), the nails, and the subcutaneous tissue. this body system covers most of the surface of the body and is the body’s first line of defense against injury and infection. functions of the integumentary system include protection, repair, sensation, vitamin D synthesis, thermoregulation, and homeostasis

diaphoresis

A

the process of sweating. the sweat itself is perspiration. sweat is secreted by the sudoriferous glands. bacteria on the skin that digest sweat produce its characteristic odor.

94
Q

scabies

A

infestation of parasitic mites that tunnel under the skin and produce vesicles that are itchy

95
Q

contact dermatitis

A

local reaction from contact with a substance that is an allergen or irritant. the skin becomes inflamed or irritated

96
Q

urticaria

A

local allergic reaction due to food, plants, animals, insect bites, or drugs. there are raised areas of redness and edema that appear suddenly. itching causes the areas to enlarge.
aka hives.
each individual area is known as a wheal. a large wheal is a welt.

97
Q

actinic keratosis

A

benign (not cancerous) neoplasm. This raised, irregular, rough area of skin is dry and feels like sandpaper. it develops in middle-aged persons in areas exposed to the sun. the area can become cancerous.
aka solar keratosis

98
Q

hemangioma

A

benign mass of superficial, dilated blood vessels that is present at birth. most disappear without treatment by age 3

99
Q

lipoma

A

benign growth of adipose tissue in the subcutaneous layer. it makes a soft, rounded, fatty elevation of the skin

100
Q

nevus

A

benign skin lesion that is present at birth and has a variety of colors and shapes
mole: a raised and round nevus
port-wine stain: a flat, red-to-purple, and irregularly shaped nevus. it can be over a large area, often on the head and neck. aka birthmark

101
Q

papilloma

A

soft, flesh-colored growth that protrudes outwardly from the skin as a flap or a polyp on a stalk. aka skin tag.

102
Q

senile lentigo

A

light-to-dark brown, flat macules on the hands and face of older adults; they occur in areas chronically exposed to the sun.

Q

syndactyly

A

congenital abnormality in which the skin and soft tissues are joined between the fingers or toes. in some cases, the nails are also joined.

104
Q

polydactyly

A

a congenital abnormality in which there are extra fingers or toes

105
Q

cancer of the skin

A

a cancerous lesion or malignancy in areas of the skin that are chronically exposed to ultraviolet light radiation from the sun. skin cancer is more common in older adults because of a lifetime of sun exposure and in fair-skinned persons because there is less melanin to absorb radiation

106
Q

basal cell carcinoma

A

skin cancer that begins in the basal (bottom) layer of the epidermis. it appears as a raised, pearly bump. it is the most common type of skin cancer, but it is a slow-growing cancer that does not metastasize to other parts of the body

107
Q

kaposi sarcoma

A

cancer of the skin and subcutaneous tissue. it is an elevated, irregular, dark reddish-blue tumor. it also involves the mucous membranes and internal organs. this previously rare cancer is now commonly seen in patients with AIDS because of their impaired immune response.

111
Q

psoriasis

autoimmune disorder that produces an excessive number of abnormal epidermal cells. the skin is itchy, red, and covered with silvery scales and plaques on the scalp, elbows, hands, and knees. illness and stress can cause a flareup, and psoriasis has a hereditary component.

112

procedure in which necrotic tissues is removed from a burn, wound, or ulcer. done to prevent infection from developing, to determine the depth of the wound, or to create a clean, raw surface that is ready to heal or receive a skin graft.

136
Q

electrosurgery

A

procedure that uses an electrical current to remove a nevus, wart, skin tag, or small malignant lesion. the electrical current passes through an electrode and evaporates the lesion.

137
Q

fulguration

A

the electrode is held away from the skin and transmits the electrical current to the skin lesion as a spark

138
Q

electrodesiccation

A

the electrode is touched or inserted into the skin lesion to deliver the electrical current

139
Q

electrosection

A

a special electrode is used that can cut and remove the lesion

140
Q

incision and drainage (I&D)

A

procedure to remove fluid or pus from a cyst or abscess.
a scalpel is used to make an incision. most of the fluid or pus is manually expressed and the remainder is allowed to drain out

141
Q

laser surgery

A

procedure that uses pulses of laser light to remove birthmarks, tattoos, enlarged superficial blood vessels (rosacea), wrinkles, scars, or unwanted hair.

142
Q

skin resurfacing

A

procedure that removes the epidermis. used to treat acne scars and skin tone irregularities, remove tattoos, and promote the regrowth of smoother skin.

143
Q

chemical peel

A

uses a liquid acid to remove the epidermis

144
Q

dermabrasion

A

uses a rapidly spinning wire brush or diamond surface to mechanically scrape away (abrade) the epidermis

145
Q

laser skin resurfacing or laser peel

A

uses a computer-controlled laser to vaporize the epidermis

146
Q

microdermabrasion

A

uses aluminum oxide crystals to abrade and remove the epidermis

147
Q

skin turgor assessment

A

assesses the patient’s level of hydration by testing the skin turgor. a fold of skin pinched between the thumb and fingertips of the healthcare professional should flatten out immediately when released. dehydration causes the fold of skin to remain elevated or to flatten out very slowly

148
Q

ultherapy

A

procedure that uses ultrasound waves directed to the dermis and subcutaneous tissues. it stimulates the production of new collagen to lift and tighten the skin of the face and neck
