INTEGRAL COMPONENTS OF CLIENT CARE Flashcards
Growth of microorganisms in body tissue where they are not usually found. Such microorganism is called an infectious agent.
INFECTION
Ability of a microorganism to produce disease. Microorganisms also vary in the severity of the diseases they produce and the degree of communicability. Ex.
Common colds
VIRULENCE
Detectable alteration in normal tissue function
DISEASE
Transferable to an individual by direct or indirect contact
COMMUNICABLE DISEASE
Ability to produce disease; thus a pathogen is a microorganism that cause disease
PATHOGENICITY
causes disease or infection in a healthy individual.
TRUE PATHOGEN
causes disease only to a susceptible individual.
OPPORTUNISTIC PATHOGEN
Freedom from disease-causing microorganisms
ASEPSIS
2 BASIC TYPES OF ASEPSIS
MEDICAL & SURGICAL
Practices that keep an area or object free of all microorganisms; practices that destroy all microorganisms and spores
Used for all procedures involving the
sterile areas of the body.
SURGICAL ASEPSIS
All practices intended to confine a specific microorganism to a specific area
Limits the number, growth, and transmission of microorganisms
Objects referred to as clean or dirty (soiled, contaminated)
MEDICAL ASEPSIS
is the condition in which acute organ dysfunction occurs secondary to infection
SEPSIS
Most common infection- causing microorganisms
BACTERIA
Spreads and damages different body parts
SYSTEMIC INFECTION
Limited to a specific body part where the microorganisms remain
LOCAL INFECTION
Primarily consist of nucleic acid and therefore must enter living cells in order to reproduce. (rhinovirus- common colds, hepatitis, HIV)
VIRUSES
Live on other living organisms (malaria, helminths- protozoa)
PARASITES
Is the process by which strains of microorganisms become resident flora. Microorganisms may grow and multiply but do not cause a disease.
Invasion to unprotected area is infection.
COLONIZATION
Yeasts and molds (candida albicans- normal flora in human vagina)
FUNGI
Systemic infection resulting from bacteremia.
SEPTICEMIA
Microorganisms reveals in the person’s blood
BACTEREMIA
May occur slowly over a long period
May lasts months or years
CHRONIC INFECTIONS
Appear suddenly or last a short period of time.
ACUTE INFECTIONS
