Anatomy & Physiology
Serving as your first line of defense against the environment, it is the skin's outermost layer.
What is the epidermis?
The term describes a completely unbroken cutaneous surface, entirely free of cuts, tear, or lesions.
What is intact skin?
This biologic process is driven by a combination of internal genetic traits and external environmental stressors.
What is skin aging?
This type of wound healing occurs when a wound naturally heals from the bottom up, commonly seen in pressure injuries.
What is secondary intention healing?
This presentation notes that pressure injuries are fundamentally this type of lesion, a term meaning they are caused by localized deficiency of blood supply.
What is ischemic?
The skin plays a crucial role in regulating this vital bodily function.
What is body temperature?
This type of wound occurs when the skin or a mucous membrane is broken, allowing blood to escape the body.
What is an open wound?
This waxy, white biofilm coats and protects the skin of a newborn baby.
What is called vernix?
Inflammation, proliferation, and maturation represent the three sequential sages the body undergoes to repair damaged tissue.
What are the phases of wound healing/
Ischemia causes this condition, which refers to the premature death of cells and living tissue.
What is necrosis?
Hair follicles, sweat glands, and nerve endings are primarily located within this thick layer of skin.
What is the dermis?
This is the bodies natural response to tissue damage or foreign organisms causing pain, erythema, edema and warmth.
What is inflammation?
In addition to a lack of subcutaneous fat, this structural skin characteristic places newborns at risk for rapid heat loss.
What is thin skin?
Dehiscence and evisceration typically manifest within a specific timeframe following a surgical procedure.
What is 4-5 days post-op?
This term describes the development of a breach or open sore on the skin's surface, which typically occurs after tissue necrosis.
What is ulceration?
This deepest skin layer is packed with fat cells that protect your body from impacts and help retain heat.
What is the hypodermis (or subcutaneous layer)?
A hard crust that covers an open wound consisting of dried plasma proteins and dead cells.
What is an eschar?
This inflammatory skin condition characterized by clogged pores typically peaks during puberty.
What is acne?
This type of wound remains open for 3-5 days to allow infection or edema to resolve.
What is tertiary healing?
Pressure injuries occur as a combination of issues such as immobility, inadequate nutrition, and advanced age.
What are risk factors?
The system regulates involuntary body processes, such as directing the skin to control temperature via sweating and changes in blood flow.
What is the autonomic nervous system?
Your skin's appearance, texture, and protective capabilities are directly influenced by these four core factors.
What are genetics, overall health, physical activity, and age?
As you age, a decrease in skin collagen and thickness causes the skin to become this.
What is be thinner and less elastic?
This fluid composed of dead cells and plasma escapes from blood vessels during the inflammatory process, taking forms such as serous, purulent, or sanguineous.
What is exudate?
An area which features a deep, severe wound with a black, necrotic center (eschar) represents this type of wound.
What is a Stage 4 pressure injury/ulcer?
