Week 3 skin Flashcards
Purpose of the integumentary system?
Protects the body, regulates temperature, and provides sensory information.
Structures of the skin?
Three layers: epidermis, dermis, and subcutaneous tissue.
Intersectionality and the integumentary system?
Examines how social identities affect health outcomes related to skin.
Assessment of the integumentary system?
Examine skin for color, texture, moisture, temperature, and abnormalities.
Purpose of diagnostics for the integumentary system?
Identify skin conditions and infections.
Inflammatory response in the integumentary system?
Includes increased blood flow and white blood cell migration to injury sites.
Types of exudate?
Serous, purulent, sanguineous, and serosanguineous.
Clinical manifestations of inflammation?
Local: redness, heat, swelling, pain; Systemic: fever, malaise.
Healing process of wounds?
Involves hemostasis, inflammation, proliferation, and remodeling.
Nursing management of inflammation and healing?
Assess wounds, provide dressings, monitor for infection.
Pressure injury and its staging?
Damage due to prolonged pressure, staged I to IV by severity.
Nursing management of pressure ulcers?
Regular assessment, repositioning, hygiene, and appropriate dressings.
Scabies and bed bugs?
Scabies: mite infestation; Bed bugs: blood-feeding parasites; treated with medications.
What skin indicates about health?
Reflects hydration, circulation, and underlying health issues.
Structure and function of the epidermis?
Protective barrier, 0.05 - 0.1mm thick, regenerates every 28 days.
Role of the dermis?
Connective tissue providing strength, contains collagen, vascular.
Subcutaneous tissue’s contribution?
Attaches skin to muscle/bone, contains fat, regulates temperature.
Main functions of the integumentary system?
Protects tissues, guards against pathogens, regulates temperature, synthesizes vitamin D.
Importance of fat in the subcutaneous layer?
Insulates and protects the body.
How often does the epidermis regenerate?
Every 28 days.
Cells in the epidermis?
Melanocytes and keratinocytes.
Composition of the dermis?
Connective tissue, highly vascular, contains collagen.
Role of melanin in the skin?
Protects against UV radiation.
Temperature regulation by the integumentary system?
Through sweat secretion and fat insulation.
