This chemical mediator increases blood vessel permeability and causes swelling.
Histamine
This is the invasion and multiplication of microorganisms in body tissues.
Infection
This type of immunity is present at birth and provides immediate defense.
Innate immunity
Which layer of the skin lacks blood vessels and nerves?
Epidermis
This is the most common cause of pressure ulcers in immobile patients.
prolonged pressure on bony prominences
This type of immune cell is dominant in chronic inflammation and helps form granulomas.
Macrophages
This type of infection is acquired in a healthcare setting.
Nosocomial Infection
hese white blood cells engulf and digest pathogens.
Phagocytes
What is a raised, thin-walled lesion containing clear fluid called?
Vesicle
This stage of pressure injury involves partial-thickness skin loss with exposed dermis
Stage II pressure injury
This is the process of replacing damaged tissue with scar tissue.
Fibrosis
This immune system component produces antibodies.
B cells
These cells help activate B cells and other immune cells.
Helper T cells
What skin condition is caused by a type I hypersensitivity reaction to ingested substances?
Urticaria (hives)
This condition, involving excess fluid in tissues, increases the risk of skin breakdown.
Edema
This protein forms the structural framework of scar tissue.
Collagen
This immune response is slower but more specific to pathogens.
Adaptive Immunity
This term describes a weakened immune system that increases susceptibility to infections.
Immunodeficiency
What are signs of cellulitis?
red, swollen, painful areas with red streaks along lymph vessels
This type of friction-related force occurs when a patient slides down in bed.
Shear
This phase of healing involves new tissue formation and angiogenesis.
Proliferative phase
This is the chain of events that describes how infections are transmitted.
Chain of infection
This type of immunity is artificially acquired through immunization.
Vaccine induced immunity
This autoimmune skin disorder causes depigmented patches due to loss of melanocytes.
Vitiligo
This systemic condition can impair circulation and delay healing of pressure ulcers.
Diabetes Mellitus
