What is the benefit of using ice on an area of the skin?
Constricts blood vessels and blood flow decreases. Can help stop bleeding, minimize swelling, reduce pain.
How long do you apply ice/heat to the skin?
no longer than 20 minutes
How long should you apply heat?

What happens to the integumentary system as we normally age?
skin loses elasticity (causing wrinkles) and becomes thinner, hair and nails grows slower, hair thins and turns gray, brown spots may appear on skin, skin becomes drier
What substance gives our skin its color?
Melanin
Closed wound
The skin's surface is not broken (ex. bruise or internal bleeding)

What will happen if skin breakdowns are unreported?
Can worsen and become infected
Psoriasis

List the functions of the skin
Covers and protects the body, provide sensations through nerves, regulates body temperature, and prevents the loss of too much water.
Gangrene
Death of tissue, caused by a lack of blood flow.
Eczema
Dermatitis. General term for a variety of skin problems. Can be a temporary or chronic skin disorder, in which redness, itching, burning, welling, cracking, or weeping of the skin can occur
2nd Degree burn (partial-thickness)
Dermis - Blisters, some skin damage, redness, pain, swelling
Why use heat on the skin?
Dilates blood vessels and blood flow increases. Relieve muscle tension, elevates temp, increases waste removal from the area, brings more oxygen and nutrients to the the tissues for healing.
Non-sterile dressings are applied for what purpose?
Dry wounds that have less chance of infection
1st degree burn (superficial)
Epidermis - Redness/pain/swelling
What are the 3 layers of skin?
Epidermis, Dermis, Subcutaeous
3rd degree burn (full-thickness)
Epidermis, dermis, and underlying layer - Bubble, white, charred/black, peeled skin, very painful, serious scarring
Tinea
Fungal infection that causes red scaly patches to appear in a ring shape.
Skin cancer
Growth of abnormal skin cells.
Why is it important to report a possible skin breakdown to the nurse?
It can help prevent serious illnesses, and can be healed quickly before other complications can occur
Where do you typically see fungal infections?
Moist areas (toes, under breasts, groin area)
What does "intergument" means?
Natural protective covering
what is the skin?
Natural protective covering, or integument, and is the largest organ.
What is the first sign of skin breakdown?

Wart
Rough, hard bumps. Contagious, caused by virus that invades the skin, usually through a cut or tear.
What is scabies?
Skin infection that causes pimple-like irritations to form on the skin. Irritations are caused by tiny mites that burrow into the skin and lay eggs
Open wound
Skin that is not intact
What's all part of the integumentary system?
Skin, hair, nails, oil glands, sweat glands, subcutaneous tissue, and nerve endings.
What will moisture from applications do to the skin?
Strengthens the effect of heat and cold (but more likely to cause injuries)
What is a sitz bath?
Warm soak of the perineal area to clean perineal wounds and reduce inflammation and pain.
Sterile dressings are applied for what purpose?
When wound is new, open, or draining, or is at higher risk of infection
