Skin, Hair, and Nails Flashcards
- physical barrier that
protects the underlying
tissues and organs from
microorganisms, physical
trauma, ultraviolet radiation,
and dehydration
SKIN
plays a vital role in
temperature maintenance,
fluid and electrolyte balance,
absorption, excretion,
sensation, immunity, and
vitamin D synthesis
SKIN
- provides an individual
identity to a person’s
appearance
SKIN
Skin is composed of three layers:
the ________________
epidermis, dermis and SQ tissue or (hypodermis)
thicker on the palms of the
hands and soles of the feet
SKIN
connected to underlying
structures by subcutaneous
tissue
SKIN
- consists of layers of
keratinized cells
HAIR
- found over much of the
body except for the lips,
nipples, soles of the feet,
palms of the hands, labia
minora, and penis
HAIR
- develops within a sheath
of epidermal cells called the
hair follicle
HAIR
- growth occurs at the base
of the follicle, where cells in
the hair bulb are nourished
by dermal blood vessels
HAIR
- shaft is visible above the
skin
HAIR
- located on the distal
phalanges of fingers and
toes are hard, transparent
plates of keratinized
epidermal cells that grow
from a root underneath the
skin fold called the cuticle
NAIL
- body extends over the
entire nailbed and has a pink
tinge as a result of the rich
blood supply underneath
NAIL
- At the base of the nail is
the _______________
unula, a paler, crescent
shaped area.
protect the distal ends of
the fingers and toes.
NAILS
To perform a complete and accurate assessment, it is
important to collect the following data;
- current symptoms
- clients past and family history
- lifestyle
- health practices
Collecting Subjective Data: Guidelines
➢ Ask straightforward questions
➢ Non-judgemental approach
➢ Skin disorders – potentially damaging to the person’s
body image and self concept
Readiness for enhanced health management: Skin Hair and Nail integrity related to healthy hygiene and skin care practices, avoidance, of overexposure to sun
Health Promotion Diagnoses
Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances. Prevents loss of moisture. Reduces harmful effects of UV radiation. Acts as a sensory organ (touch, detects temperature)
structure and function of the skin
Each hair has a hair shaft and a hair root. The shaft is the visible part of the hair that sticks out of the skin. The hair root is in the skin and extends down to the deeper layers of the skin. It is surrounded by the hair follicle (a sheath of skin and connective tissue), which is also connected to a sebaceous gland
structure and function of the hair
Nails are accessory organs of the skin. They are made of sheets of dead keratinocytes and are found on the far, or distal, ends of the fingers and toes. The keratin in nails makes them hard but flexible. Nails serve a number of purposes, including protecting the digits, enhancing sensations, and acting like tools

structure and function of the nail
protect the sensitive tips of fingers and toes. We don’t need our nails to survive, but they do support the tips of our fingers and toes, protect them from injury, and help us pick up small objects. Without them, we’d have a hard time scratching an itch or untying a knot.
purpose of the nails
The hair on our heads doesn’t just look nice. It keeps us warm by preserving heat. Hair in the nose, ears, and around the eyes protects these sensitive areas from dust and other small particles. Eyebrows and eyelashes protect eyes by decreasing the amount of light and particles that go into them.
purpose of the hair
Skin warm, dry, with good turgor, No abnormal pigmentation, bleeding, rash, or other lesions.
Normal findings of skin
Normal terminal hair is black, brown, red, yellow, or variations in shades of these colors. The hair is coarse of fine and shinny
Normal findings of hair
Normal nails are translucent, shiny and firm in texture.
Longitudinal bands of pigment can normally be seen in black patients.
With aging nails may lose their luster, thicken and become yellow.
Longitudinal ridging also develops with aging.
Normal findings of nail
iscoloration (dark streaks, white streaks, or changes in nail color) changes in nail shape (curling or clubbing) changes in nail thickness (thickening or thinning)
abnormal findings of the nail
Alopecia (nonscarring). Skin disorders, certain drugs, certain diseases, autoimmunity, iron deficiency, severe stress, scalp radiation, pregnancy, or pulling at your own hair.
Alopecia (scarring). …
Hirsutism. …
Hair shaft disorders. …
Inflammation.
