Question 1 Not yet graded / 0 pts
What is the definition of “pathophysiology”?
Your Answer:
Changes to the bodies physiology caused by disease.
Pathophysiology is 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.
Question 2 Not yet graded / 0 pts
Name the 5 etiologic factors and give an example if listed.
Your Answer:
1: genetic: cogential heart defects
2: environmental: pollution
3: combo of both: lung disease from pollution
4: injury:; broken bone
5: lack of O2
Biologic agents (bacteria, viruses), physical forces (trauma, burns, radiation), chemical agents (poisons, alcohol), one’s genetic
inheritance, and nutritional excesses or deficiencies.
Question 3 Not yet graded / 0 pts
What are the 2 types of risk factors?
Your Answer:
congenital conditions and acquired defects
Risk factors can be categorized as congenital conditions (present at birth) or acquired defects (occurring after birth).
Question 4 Not yet graded / 0 pts
What is the difference between morphology and histology?
Your Answer:
, Question 6 Not yet graded / 0 pts
What are 3 important processes when coming to a diagnosis?
Your Answer:
looking at the symptoms of the pt
pt signs and pt history
diagnostic testing
The diagnostic process requires a careful history, physical examination (PE), and sometimes diagnostic tests.
Question 7 Not yet graded / 0 pts
Explain validity, reliability, sensitivity, and specificity.
Your Answer:
validity - ability to distinguish between who has a disease and who does not
sensitivity - ability to test to identify correctly those that have the disease.
specificity- ability of a test to correctly identify those who do not have the disease
reliability- how well the test works and how accurate the readings are.
Validity is how a tool measures what it is intended to measure. Reliability is how likely the same result will occur if repeated.
Sensitivity is 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.
Question 8 Not yet graded / 0 pts
Define epidemiology and name some things that it tracks.
Your Answer:
epidemiology is the study of the disease occurrence in a population
some things it tracks are: prevalence (# of ppl who have the disease at a particular time), incidence (# of NEW cases arising in the pop and a
specific time), Morbidity (the affects of the disease on a persons life), and mortality ( death rate statistics in the pop from disease)
Epidemiology is the study of disease occurrence in human populations. It tracks age, race, dietary habits, lifestyle, or
geographic location.
Question 9 Not yet graded / 0 pts
What is the difference between incidence and prevalence?
Your Answer:
prevalence looks at the total number of people in the population who have the disease at a specific time where as incidence look at the number
of new cases in the population at a specific time
Incidence is the number of new cases in a population at risk during a specified time. Prevalence is the number of people with
the disease in a population in a given time.
