Portage Pathophysiology Exam 1, 2, 3,
4, 6, 7&9 Test Bank Questions and
Correct Answers Updated &Already
Graded A
give one function of a membrane potential
Generate nerve impulse, muscle contractions, or cause hormone secretion
What is the term to describe when cells use energy to move ions against an electrical or chemical
gradient?
active transport
What term means "cell eating" and engulfs and then kills microorganisms or other particulate
matter?
phagocytosis
What is the term to describe when cells use energy to move ions against an electrical or chemical
gradient?
active transport
Give one function of a membrane potential:
Generate nerve impulse, muscle contractions, or cause hormone secretion
what is diffusion of water called?
osmosis
cervical intraepithelial neoplasia is a type of dysplasia? t or f
true
,endometrial hyperplasia is a normal physiologic occurrence. t of f
false
validity
how a tool measures what it is intended to measure
reliability
how likely the same result will occur if repeated
sensitivity
The proportion of people with a disease who test positive.
specificity
people without the disease who are negative on a given test
Definition of Pathophysiology
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
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
congenital factors (present at birth) or acquired (occurring after birth)
,Difference between morphology and histology
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
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?
Patient history, physical examination, and diagnostic tests.
Validity, reliability, sensitivity, and specificity definitions.
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.
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
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
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.
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.
Tertiary: occurs after a diagnosis has been made and clinical interventions are needed to reduce
complications.
Why is evidence based practice important?
Evidence-based practice is the conscientious, explicit, and judicious use of current best evidence
in making decisions about the care of individual patients. This is to counteract "the way things
have always been done," and to practice based on clinical research.
what are the 3 primary structures of the cell?
Nucleus, cytoplasm, and plasma membrane
What is the function of the nucleus?
control center of the cell and contains DNA and RNA
Name 3 structures within the nucleus
