What are the major functions of the integumentary system?
1. *Prevents penetration: barrier
2. *Protection: physical, chemical and thermal
3. Regulation: temperature
4. Perception: sensory organ (pain, touch, pressure,
temperature)
Other functions
Identification
Communication
Wound repair
Absorption/excretion
Production of vitamin D
Functions of Hair
Provides ……..Warmth
Protection
Sensation
………to underlying structures
Functions of Nails
Provides ….Protection to distal surfaces
Can be used for self-protection
Subjective Data
Health history
(blue pages)
Integumentary System-Health History
any past skin problems and their management
skin colour changes
temperature changes
texture changes
sweating
any masses including warts or moles (nevi)
Integumentary System-Health History
changes in masses, warts, nevi – also, cosmetic concerns and physical discomfort
rashes or eruptions
changes in hair texture or oiliness, hair loss, dandruff, hair bleaching, dyeing
management of any problems with hair or scalp
medications
Integumentary System-Health History
complaints of tenderness, flakiness, itchiness, lumps, sores on scalp, bleeding
problems with nails including breaking, ingrown nails, paronyhia (hangnails), nail biting
Self-care behaviours
Describe how to assess the client’s integumentary system by inspection and palpation?
Inspection and Palpation
1.How will you prepare the environment?
2. How will you prepare the client?
3.How will you protect the client’s privacy?
*4. What equipment is needed?(Direct lighting, small ruler, penlight,
gloves)
Objective Data
What are the general characteristics of the skin that should always be noted?
Inspection and Palpation of the skin
Inspect Colour
General pigmentation: freckles, mole (nevus), birthmarks.
Widespread colour changes: pallor, erythema, cyanosis, jaundice.
Palpate Temperature
Should be warm & equal bilaterally
Hypothermia: immobilized extremity, cast, IV (normal)
Hyperthermia: fever, exercise, trauma, infection or sunburn.
Palpate Moisture
Normal perspiration
Diaphoresis
Dehydration in mucous membranes
Palpate Texture
Smooth and firm
Even texture
Palpate Thickness
Epidermis is thin over most of the body
Calluses over palms and soles
Palpate Edema
Not normally present
Scale from 1+ to 4+
Most evident on feet, ankles, and sacral areas
Note extent and location
Palpate Mobility and Turgor
Mobility is the skin’s ease of rising
Turgor is its ability to return to place promptly.
Pinch up on skin and let go (ant. Chest under clavicle)
Inspect Vascularity or Bruising
Cherry (senile) angiomas
Ecchymosis (bruising): consistent with traumas of life.
Tattoos: document location on chart.
Inspect Lesions
1. Colour2. Elevation3. Pattern or shape (p.250-251)4. Size in cm (avoid quarter or pea)5. Location and distribution on body-
e.g. generalized or localized6. Exudate, note colour and odor
(See OH for images on p 290 -293)
Danger Signs….ABCDE
Asymmetry of a pigmented lesion
Border irregularity
Colour variation
Diameter greater than 6 mm
Elevation and enlargement(any change)
How do you examine a lesion?
Palpate, wear gloves
Roll nodule between thumb and forefinger to assess depth
Does it blanche with pressure or when stretched?

What are the criteria used in assessing the hair and scalp?
Inspection and Palpation of the hair and scalp
Inspect Colour
Pale blonde to total black
graying
Palpate Texture
Fine or thick
Straight, curly or kinky
shiny
Palpate Distribution
Fine hair coats the body
Coarse hair at the eyebrows, eyelashes and scalp
Puberty: hair to face (male), axillae and pubic region
Inspect Lesions
Clean and free from lesions
No nits or head lice
Seborrhea (dandruff) is normal
What criteria are used in assessing nails?
Inspection and Palpation of the nails
Inspect Shape and contour
Normally slightly curved or flat
Nail folds smooth and rounded
Nail edges are smooth, rounded and clean.
Normal nail angle- 160 degrees
Clubbing: occurs with long standing hypoxia - emphysema and chronic bronchitis
Inspect Consistency
Smooth and regular, not brittle or splitting
Thickness is uniform throughout nail
Nail firmly attached to nail bed
Inspect & Palpate Colour
Nail bed is pink
Brownish-black linear bands or streaks along the nail edge in dark-skinned individuals
White hairline linear markings usual as well.
Capillary refill: colour return is instant or within a few seconds. A sluggish return takes longer than 1 to 2 seconds.
