NURS319 - SKIN EXAM QUESTIONS AND CORRECT ANSWERS
integumentary system
The _________________ includes skin, hair, nails, sweat glands, and oil glands. The
largest and most visible of all organs, skin serves as an effective barrier between the
outside environment and the internal concerns of the body, aids in the regulation of
body temperature and in maintaining fluid and electrolyte balance.
epidermis, dermis, and subcutaneous layer
Skin is composed of three layers of tissue:
true
Each layer of skin is unique in structure and function and forms the basis for how
medications are administered either by injection or topically.
epidermis
The ___________ is the visible, outermost layer that makes up about 5% of the depth of
the skin. The epidermis has either four or five sublayers depending on its thickness.
stratum basale (also called the stratum germinativum); stratum spinosum, stratum
granulosum, stratum lucidum, stratum corneum.
five layers from innermost to outermost:
stratum corneum
The ______________ contains abundant amounts of the protein keratin that provides an
effective barrier that repels bacteria and other foreign matter: most substances are
unable to penetrate this barrier.
stratum basale
The deepest epidermal layer, the ____________, supplies the epidermis with new cells
after the older superficial cells have been damaged or lost by normal wear.
On average its takes about __ weeks to move from the stratum basale to the body
surface.
melanocytes
Specialized cells within the deepest layers of the epidermis, called ____________,
secrete the dark pigment melanin, which offers a degree of protection from the suns
ultraviolet rays. The number and type of melanocytes determine the overall pigment of
, the skin. The more melanin, the darker the skin dermis
The middle layer of the skin is the _________, which accounts for about 95% of the skins
thickness. The dermis provides a foundation for the epidermis and accessory structures
such as hair and nails. Most sensory nerves that transmit the sensations of touch,
pressure, temperature, pain, and itch are located within the dermis as are oil glands and
sweat glands.
hypodermis
Underlying the dermis is the subcutaneous tissue, or ___________, which is primarily
composed of adipose tissue that cushions, insulates, and serves as an energy reservoir
for the body.
urticaria
___________ is a hypersensitivity reaction that appears as hives, but is often itchy as well
as eruptions can exhibit pruritis, or itching. Food allergies sometimes show up this way.
pruritus
Pruritis is a general condition associated with dry, scaly, skin, or a parasite infection.
may also be a sign of systematic pathology, such as serious hepatic or renal
impairment.
true
A significant number of drugs have urtica or pruritis listed as potential adverse effects.
erythema
_____________, or redness of the skin, accompanies inflammation and many other skin
disorders. Inflammation is a characteristic of burns and trauma to the skin.
infectious, inflammatory, or neoplastic
One simple method of distinguishing skin disorders is to group them into:
Infectious
bacterial, fungal, parasitic and viral infections
Inflammatory
trauma and severe sunburn. Overgrowth of glands, excessive production of hormones,
or an infection such as acne and rosacea. Diseases that cause itching, cracking and
shedding like atopic dermatitis, contact dermatitis, seborrhoeic dermatitis, stasis
dermatitis and psoriasis
Neoplastic
