Pathophysiology chapter 1 terms

Pathophysiology

the study of the functional changes that occur in the body as a result of an injury, disorder, or disease.

pathology

study of changes in cells and tissues as a result of injury or disease

physiology

the mechanisms of human body functioning

Disease

the functional impairment of cells, tissues, organs, or organ systems.

Syndromes

a specific condition with a recognizable, predictable pattern

pathogenesis

the origination and development at the point of disease onset.

Etiology

precise cause of disease

pathogen

disease causing microorganism

multifactorial

having more than one genetic and/or environmental causing events

idiopathic

no known etiology (no precise cause for the disease)

nosocomial

disease resulting from exposure to infection in the health care environment

iatrogenic

disease resulting from the inadvertent result of medical treatment

clinical manifestations

the presenting signs and symptoms of the disease

precipitating factors

triggers that promote the onset of clinical manifestations

local manifestations

found directly at the site of disease and confined to that area

systemic manifestations

present throughout the body

acute

begin abruptly and last a few days to a few months

chronic

last longer than 6 months

insidious

disease having a gradual onset

remissions

symptom-free periods of a chronic disease

exacerbations

flaring of symptoms in a person with a chronic disease

subacute

disease that falls between acute and chronic in duration and severity

asymptomatic

no noticeable symptoms even though diagnostic tests indicate presence of disease

diagnosis

label for the disease

nursing diagnosis

description of the human response to disease

prognosis

prediction of how the individual will proceed through the disease process

morbidity

a negative outcome with disease complications that impact the quality of life and possibly death

mortality

death

health

the perceived wholeness of the body, mind, and spirit

illness

a state that results in suffering. *(health and illness are on a dynamic continuum)

homeostasis

dynamic balance in the body marked by appropriate and effective response to stimuli

epidemiology

the study of disease in populations

incidence

the rate of occurrence of a disease (probability that a disease will occur in a certain population)

prevalence

(epidemiology) the ratio (for a given time period) of the number of occurrences of a disease or event to the number of units at risk in the population

endemic

when incidence and prevalence of a disease are predictable

epidemic

a dramatic increase in disease incidence in a population

pandemic

when and epidemic spreads across continents

primary prevention

prohibits a disease condition from occurring

secondary prevention

early detection and treatment of disease through screening

tertiary prevention

rehabilitation of a patient after detection of disease

concept

a general idea that can be applied to similar situations
