Portage Pathophysiology Module 1
Exam And All Correct Answers 2024.
What is the definition of pathophysiology? - Answer the study of the body's response to altered
function or disease
Name the 5 etiologic factors and give an example - Answer 1. physical force (burns)
2. chemical agents (poison)
3. bioloigcal agents (bacteria)
4. genetic predisposition
5. nutritional excesses/deficiencies
What are 2 types of risk factors? - Answer congenital and acquired
What is the difference between mophology and histology? - Answer morphology is the structure of cells
or tissues whereas histology is the study of cells at the tissue level
Describe the difference between signs and symptoms and given an example of each - Answer A sign is
an objecetive manifestation (fever, edema) whereas a symptom is a subjective complaint (dizziness, pain,
difficulty breathing)
What are 3 important processes when coming to a diagnosis? - Answer 1. patient history
2. physical examiniation
3. diagnostic testing
Define epidemiology and some things that it tracks - Answer The study of disease occurence in human
populations. For example, they may track age, rae, nutritional habits, lifestryle, and/or geographic
location
Incidence - Answer the number of new cases in a population at risk during a specified time
, Prevalence - Answer number of people with the disease in a population at a given time
Validity - Answer how a tool measures what it is intended to measure
Reliabilty - Answer likelihood of the same result occuring with repeated testing
Sensitivity - Answer proportion of people with a disease who test positive for that disease
Specificity - Answer people without tthe disease who test negative for that disease
Mortality - Answer Cause of death in a population; death rate
Morbidity - Answer effect of an illness on one's life
Primary Prevention - Answer Attempts to elimiate risk factors in order ro prevent disease from occuring
(ex: taking a multivitamin to prevent nutritional deficiencies)
Secondary Prevention - Answer aims to detect and treat disease early, usually while the disease is
asymptomatic and curable (ex: going to the doctor for an annual pap smear)
Tertiary Prevention - Answer occurs after a diagnosis has been made, and clinical intervention is needed
to reduce complications and/or deterioration (ex: use of prescribed medication after a heart attack to
reduce the risk of a future event or death)
Why is evidence-based practice important? - Answer By relying on current best, scientific evidence, one
can make the best decision regarding a patients health rather than saying "this is the way it has always
been done"
What are 3 primary structures of the cell? - Answer 1. nucleus
2. plasma membrane
