answers A+ Grade
Definition of Pathophysiology
- correct answer defined as not only the cellular and organ changes that occur with disease, but also the
effects that these changes have on total body function.
5 etiologic factors and an example of each
- correct answer Biological: bacteria and viruses
Physical: trauma, burns, and radiation
Chemical: poisons, drugs
One's genetic inheritance
Nutritional excesses or deficiencies
2 types of risk factors
- correct answer congenital factors (present at birth) or acquired (occurring after birth)
Difference between morphology and histology
- correct answer Morphology - fundamental structure or form of cells or tissues (includes the gross and
microscopic changes)
Histology - study of the cells and extracellular matrix of body tissues (at the tissue level)
Signs and symptoms
- correct answer Signs - objective and can be seen or measured. Elevated temp, leg edema, and changes
in pupil size.
symptoms - subjective. pain, trouble breathing, dizziness.
3 important processes when coming to a diagnosis?
- correct answer Patient history, physical examination, and diagnostic tests.
, Validity, reliability, sensitivity, and specificity definitions.
- correct answer Validity - how a tool measure what it is intended to measure.
Reliability - likelihood the same result occurring with multiple testing.
Sensitivity - the proportion of people with a disease who are positive for that disease.
Specificity - are people without the disease who are negative on a given test.
Define epidemiology and name some thing that it tracks.
- correct answer Epidemiology is the study of disease occurrence in human populations. It tracks, age,
race, dietary habits, lifestyle, or geographic location.
Difference between incidence and prevalence
- correct answer Incidence - the number of new cases in a population
Prevalence - the number of people with the disease in a population in a given time
Define Mortality and Morbidity
- correct answer Mortality - the statistics that deal with cause of death in a population
Morbidity is the effect of illness on one's life.
Define Primary, secondary, and tertiary prevention and give an example of each.
- correct answer Primary: remove risk factors to prevent disease from occurring. Examples - yearly check
up, daily vitamin, vaccination, wearing seatbelts or helmets.
Secondary: detect and treat disease early, usually while the disease is asymptomatic and curable.
Example - pap smears, checking bp and cholesterol and colonoscopy screening. Usually all done by
setting of a physician.
