WEEK 2-ATI Flashcards
alterations in tissue integrity
layers in the skin
epidermis
dermis
hypodermis
epidermis layers
made of up of four or five layers depending on the area of your body (soles of the feet require 5 since it’s thicker skin in that area)
what does the epidermis serve as
the outermost layer of the skin and provides the waterproof nature of the skin and influences skin color
contains natural flora, which is not pathogenic in the body’s normal state
common skin bacteria
Staphylococcus epidermitis, aureus, and cutibacterium acnes
dermis
directly beneath the epidermis
dermis layer
contains 2 layers
The sweat glands, hair, hair follicles, muscle, sensory neurons, and blood and lymphatic vessels are in the dermis.
hypodermis
deepest layer and is also referred to as the subcutaneous fascia
what does the hypodermis contain
This layer contains adipose lobules and connective tissue, as well as hair follicles, sensory neurons, and blood vessels.
who has thinner skin
children and people after the fifth decade
causes of skin pathologies
Allergens, injury, irritants, diseases, immune responses, and genetics
define skin wound
disruption in the epidermal layer that can go deeper into the dermis or subcutaneous tissue.
what happens during the first stage of wound healing
clotting is initiated
vasoconstriction occurs
fibrin mesh is established
vasodilation occurs
causing hyperemia and edema
neutrophils are recruited to kill bacteria and debride necrotic tissue
proliferation
starts from day 3-day 10 and takes weeks to complete
It is characterized by granulation tissue and repair of vascular structures. The new vascular network brings nutrients to help heal the wound. Epithelialization begins. Fibroblasts proliferate to the wound, and granulation tissue develops.
tissue remodeling
occurs from day 21 up to a year
During the remodeling phase, the balance of synthesis of new cells and degradation of tissue is no longer needed. Collagen strengthens the wound.
clients at risk for skin injuries
advanced in age, multiple health problems, physical limitations, poor nutrition, incontinence, poor circulation and oxygenation, decreased sensation, altered cognition, and taking multiple medications.
alterations in skin integrity can occur for a variety of reasons, including…?
moisture, friction, shearing, pressure, burns, and trauma.
friction
Mechanical force of dragging skin across surface.
shearing
The force of body structures upon the skin, moving in opposite direction.
a common cause of moisture-related skin conditions
incontinence
incontinence-associated dermatitis (IAD)
caused by prolonged exposure to moisture from urine and stool.
intertrigo
inflammation of the skin on surfaces that have folds, such as between the fingers, axilla, and under breasts.
example of shearing
An example is the shearing force of the coccyx on the subcutaneous tissues and the friction of the skin surface as the body slides down or is pulled up in bed
friction vs. shearing
Friction affects the superficial layers, whereas shearing affects the deeper tissues.
who is at the highest risk for skin tears
clients older than 65 because aging and fragile skin is more susceptible to separating and tearing
