Exam 1 Full Overview Flashcards
A state of optimal physical, mental, and social well-being; means different things to different people
Health
Disease of body or mind
Illness
What illness persists for a long time
Chronic
What illness develops suddenly and resolves in a short time
Acute
What illness is there no cure for and ends in death
Terminal
What illness develops without being caused by another health problem
Primary
What illness results from a primary illness
Secondary
What illness is present at birth
Congenital
What illness starts with no known cause
Idiopathic
What are the stages of illness
Transition, acceptance, convalescence
What stage- the onset of illness may consist of vague, nonspecific symptoms
Transition
What stage- the person stops denying illness and assumes the “sick role”
Acceptance
What stage- the process of recovering after the illness and starts regaining health
Convalescence
What are some variable that influence health and illness
Genetic influence, age, sex, culture, religion, beliefs, previous health experiences
Any action undertaken to promote health, prevent disease, or detect disease in an early asymptomatic stage
Health behavior
Without symptoms
Asymptomatic
Any activity someone takes to determine their actual state of health and to seek a suitable remedy for a health problem
Illness behavior
Considers the persons biologic, psychological, sociological, and spiritual aspects and needs
Holistic approach
What are Maslow’s hierarchy of needs in order
Physiologic, safety and security, love and belonging, self-esteem, self-actualization
Tendency of biologic systems to maintain a state of internal environment by continually adjusting to changes needed for survival
Homeostasis
Occurs in response to long-term exposure to stress
General adaptation syndrome
What are the stages of general adaptation syndrome
Alarm, resistance, and exhaustion
What stage- hormone release mobilizes the body defenses
Alarm stage
What stage- the body is battling for equilibrium
Stage of resistance
What stage- occurs when stress is present over a long enough time to deplete the body’s resources for adaptation
Stage of exhaustion
Adjusting to or solving challenges
Coping
Strategies that protect us from increasing anxiety; used to maintain and improve self-esteem
Defense mechanisms
Avoids or delays occurrence of a specific disease or disorder
Primary prevention
Following guidelines for screening for diseases that are easily treated if found early
Secondary prevention
Rehabilitation measures after the disease or disorder has stabilized
Tertiary prevention
The entry of a microorganism into the body that multiplies and disrupts tissue integrity
Infection
Microorganisms capable of causing disease
Pathogens
Single-cell microorganisms lacking a nucleus that reproduce from every few minutes up to several weeks
Bacteria
How is bacteria classified
need for oxygen, shape, and Gram staining properties
What bacteria needs oxygen to live and grow
Aerobic
What bacteria only grown in the absence of oxygen
Anaerobic
Chemical substance that can kill or alter the growth of bacterial organisms
Antibiotic
Extremely small particles of nucleic acids, either DNA or RNA, with a coat of protein, and in some cases a membranous envelope, that can trigger in immune reaction or damage cells in other ways
Viruses
Tiny, primitive organisms of the kingdom fungi that contain no chlorophyll that thrive in warm, moist environments
Fungi
Killing or suppressing growth of microorganisms
Antimicrobial
What is the chain of infection
Process by which an infection is spread from one person to another; infectious agent, source, portal of exit, mode of transmission, portal of entry, susceptible host
What is an infectious (causative) agent and examples
Any microorganism or biologic agent capable of causing disease; bacteria, virus, parasite, fungus
What is a source (reservoir) and examples
Places where microorganisms are found; animal, insect, inanimate object, human
What is a portal of exit and and examples
Route by which a pathogen leaves the body of its host; respiratory tract, GI tract, blood, skin/mucosal surfaces
What are examples of modes of transmission (transfer)
Contact, airborne, droplet, vector-borne
What is portal of entry and examples
Pathogens enter the body through the mucous membrane; GI tract, nonintact skin, respiratory tract
What are examples of susceptible host
Immunosuppressed, trauma, surgery, chronically ill, and elderly
What is the first line of defense
Intact skin
What is the second line of defense
Helps destroy pathogens that escape the first line
Slows the growth of microorganisms
Fever
Increased production of leukocytes (WBC)
Leukocytosis
Eat bacteria, work to destroy or stop invasion
Phagocytosis
Localized response to injury
Inflammatory response
Interferes in the replication of many viruses; in response to viral invasion
Interferon
What is the third line of defense
Immune response
Immunity where the fetus receives antibodies from the mother
Naturally acquired passive immunity
