9 a Flashcards
skin meaning
Skin is a dynamic organ in a constant state of
change; cells of the outer layers continuously shed and are replaced by inner cells
moving to the surface.
the largest organ of the body, making up 16% of body weight
skin function
immune function, temperature regulation,
sensation and vitamin production.
acute wound example
is the result of tissue damaged by trauma. This may be
deliberate, as in surgical wounds of procedures, or be due to accidents caused by
blunt force, projectiles, heat, electricity, chemicals or friction.
CHRONIC wound
fails to progress or respond to treatment over the normal
expected healing time frame (4 weeks) and becomes “stuck” in the inflammatory
phase.Wound chronicity is attributed to the presence of intrinsic and extrinsic
factors including medications, poor nutrition, co-morbidities or inappropriate
dressing selection
LAYERS OF SKIN
Epidermis
demis
hypodermis
epidermis
Is the outer layer of the skin, comprised of epithelial cells
Regenerated every 2-4 weeks, subject to an individual’s
age and friction forces applied to the skin
Receives nutrients from the dermis below
Comprised of 4 to 5 layers depending on the body location
Dermis
The middle layer of the skin, made up of two layers
Contains nerves, connective tissue, collagen, elastin and
specialized cells such as fibroblasts and mast cells
Responsible for inflammatory reactions which occur in
response to trauma and infection
Has receptors for heat, cold, pain, pressure, itch and
tickle
Hypodermis:
Is the inner most layer of the skin, referred to as the
subcutaneous layer
Supports the dermis and epidermis
Comprised of adipose tissue, connective tissue and blood
vessels
Functions to store lipids, protect underlying organs,
provide insulation and regulate temperature
ASSESSMENT
History
The patient’s medical, surgical, pharmacological and
social history
Examination
Of the patient as a whole; then focus on the wound

Inspection/Observation
Look:
Colour of the skin (is it pale/flushed, cyanotic, burned tissue)
Rash: Note the size, colour, texture and shape of the lesions (e.g.: raised or flat, fluid
filled) and the number and distribution (e.g.: sparse, numerous, over limbs etc.), itchy,
painful.
Note which area of the body it covers.
Bruising/wounds/pressure injuries: Assess any existing wounds and utilise a Wound Care
Assessment tab in the EMR flowsheet for ongoing wound assessment and management.
Examine high risk areas regularly, including bony prominences and equipment sites
(masks, plasters, tubes, drains, etc.) for pressure injuries. Report any irregular
bruising.
Nevi/Moles: Observe for size, any irregular borders, variation in colours. Larger nevi
and changing ones should be reviewed by appropriate medical staff.
Hair: observe the condition ( especially the scalp) Cradle cap is most common in
newborns and is identified by thick, crusty scales over the scalp. Observe for lice or
ticks
Palpate:
Skin temperature, moisture, turgor, oedema, deformities, haematomas and crepitus
Hair texture for brittleness, moisture
