Applied Pathophysiology Exam 1 | Definitions,
Epidemiology & Diagnostics | Actual Exam
Q&A Verified and A+ Graded
Define pathophysiology
The study of the body's response to dysfunction or disease,
Define pathogenesis
Sequence of events from the initial stimulus to the expression of the disease,
Define etiology
The study of the causes of disease,
Define diagnosis
The identification of a disease based on signs, symptoms, and tests,
Define clinical manifestations
Signs and symptoms that reflect the disease's presence,
Define clinical course
The evolution of a disease, including stages (acute, subacute, chronic, etc.),
Define reliability (in testing)
Ability of a test to give the same result when repeated,
Define validity (in testing)
Extent to which a test measures what it is intended to measure,
Define sensitivity
Proportion of true positives, ability to identify those with disease,
Define specificity
Proportion of true negatives, ability to identify those without disease,
Define epidemiology
Study of disease occurrence in human populations,
, Define incidence
Number of new cases of a disease in a population over a given time,
Define prevalence
Total number of existing cases in a population at a given time,
Define morbidity
Effects of an illness on a person's life,
Define mortality
Number of deaths in a population due to a disease,
Define natural history of a disease
Progression of a disease without medical intervention,
Define prognosis
Expected outcome and chance of recovery,
What is primary prevention
Removing risk factors before disease occurs (e.g., immunizations),
What is secondary prevention
Early detection and treatment while disease is curable (e.g., Pap smear),
What is tertiary prevention
Preventing complications or further deterioration (e.g., rehab),
Chapter 3 - Cellular Adaptation
Injury, and Death
Why do cells adapt
To survive and maintain function in response to stress or changes,
Define atrophy
Decrease in cell size (e.g., disuse muscle wasting),
Define hypertrophy
Increase in cell size (e.g., enlarged heart from hypertension),
