Integumentary System

Layer of Skin that contains dead skin cells

Epidermis (outer layer of skin)

Nerve receptors within the skin

Pacinian Corpuscle

Carries oxygen to the skin cells

Blood vessels

Connected to the hair follicle and secretes oil

Oil gland

Layer of skin that contains fatty tissue

Hypodermis

Protects skin from UV

Melanocyte

Gets rid of excess water and salts

Excretion (sweat gland)

Barrier to UV rays and pathogens

Epidermis (protect)

Nerves respond to pain, pressure, & temp

Sensory perception (pacinian corpuscle)

Blood vessels dilate(heat)contract(cold)- sweat is released to cool body

Temp. Regulator (Blood vessels and sweat glands)

Creates vitamin D from sun exposure

Production(melanocyte)

Absorbs certain chemicals through skin

Absorption

Temporary storage of fat, glucose

Storage

Absence of skin color (danger?)

Albino (extremely sensitive to sunlight/burns easily)

Pallor

What am I checking for in edema/how do I preform test

Ck for swelling of tissue fluid/press firmly on lower leg and observe how long a ‘pit’ remains after you remove your thumb

What am I cking for in blanching/how to preform test

Ck circulation/press thumb firmly on pts fingernail, release and time how fast color returns to normal, if it’s slow-poor circulation

What am I cking for in Turgor/how do I preform test

Ck for hydration/pinch area of skin on back of hand or arm, release and time how fast the skin reverts back to original place, if it’s 3 seconds and above their dehydrated

Normal range of oral temp

97.7-100.9 WNL

Most accurate temp site

Rectal/common in newborns

Least accurate temp site

Axillary (armpit) -common for newborns, babies, toddlers

Oral temp site

Most common and convenient-do NOT use w/ toddlers/confused pts

Aural(Tympanic) body temp site

Ear canal, common in infants/toddlers

Common triggers that raise temp.

Infection (Febrile(Fever)), exercise, high environmental temp

Common triggers that lower temp

Blisters w/ clear fluid

Vesicles- ex. Chickenpox

Firm, raised areas on skin

Papules- ex. Chickenpox, pimples

Signs of skin cancer

Change in size/shape/color of mole, bleeding/itching

Highly contagious skin infection caused by staphylococcus or strep/Tx/S&S

Impetigo- S&S(erythema,pustules,yellow crust) - Tx: wash lesions w/ soap & water; antibiotics

Which diseases are contagious

Rosacea

Flares and remission, typically older adults, redness flushing of skin, red bumps, cortisone cream, no cure
