A+,GUARANTEED PASS.
What is the definition of "pathophysiology"? - CORRECT
ANSWERS-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.
Name the 5 etiologic factors and give an example if listed. -
CORRECT ANSWERS-Etiologic factors are the causes of a
disease.
1. Physical forces: trauma, burns, etc
2. Chemical agents: poisons, alcohol
3. Biological agents: bacteria, viruses
4. Genetic predisposition: inherent genes from both parents but
you don't necessarily develop the disease but are
predispositioned to it
5. Nutritional excess or deficiencies: Iodine deficiency can lead to
hypothyroidism. Nutritional excess in carbohydrates can lead to
irritable bowel syndrome.
What are the 2 types of risk factors? - CORRECT ANSWERS-
Congenital: present at birth
Acquired: occur after birth
What is the difference between morphology and histology? -
CORRECT ANSWERS-Morphology is defined as the fundamental
,structure or form of cells or tissues. Histology is the study of the
cells and extracellular matrix of body tissues.
Describe the difference between signs and symptoms and give
an example of each. - CORRECT ANSWERS-These both relate to
manifestations of a disease. Signs is an objective manifestation
while symptoms are a subjective complaint. Signs are apparent
to the physician, symptoms are apparent to the patient.
What are 3 important processes when coming to a diagnosis? -
CORRECT ANSWERS-Patient history, diagnostic testing, and a
physical examination.
Explain validity, reliability, sensitivity, and specificity. - CORRECT
ANSWERS-Validity: how a tool measures what it is intended to
measure i.e. the correct tool to do the job, such as using a blood
pressure cuff to measure blood pressure
Reliability: likelihood of yielding the same result of a test, usually
dependent on someone's experience and skill level
Sensitivity: proportion of people with a disease who test positive
Specificity: people without the disease who test negative for it
Define epidemiology and name some things that it tracks. -
CORRECT ANSWERS-Epidemiology is the study of disease
occurrence. It tracks the health of a community by tracking age,
race, nutritional habits and locations.
What is the difference between incidence and prevalence? -
CORRECT ANSWERS-Incidence is the number of new cases in the
population at a given time, prevalence is the number of cases
that exist in the population at a given time.
, Define mortality and morbidity. - CORRECT ANSWERS-Mortality is
the reason for death in a population. Morbidity is the effect of the
illness on someone's life, as it pertains to their quality of life.
Define primary, secondary, and tertiary prevention and give an
example of each. - CORRECT ANSWERS-Primary prevention is
what a person does to prevent a disease from occurring, for
example eating healthy and exercising.
Secondary prevention is aiming to detect and treat diseases
when they are either still curable or asymptomatic. An example
of this is a colonoscopy
Tertiary prevention is when a disease is diagnosed and clinical
interventions happen to cause further complications. For
example, using medication to reduce the risk of future heart
attacks.
Why is evidence-based practice important? - CORRECT
ANSWERS-Evidence-based practice is important because medical
professions follow up-to-date information and studies in order to
treat diseases. This ensures that new treatment options are
followed, preventing physicians from using outdates practices
that no longer benefit the patient.
What are the 3 primary structures of the cell? - CORRECT
ANSWERS-The nucleus, cytoplasm, and plasma membrane
What is the function of the nucleus? - CORRECT ANSWERS-The
nucleus is the control center for the cell and contains most of
the hereditary material, DNA and RNA.
Name 3 structures within the nucleus. - CORRECT ANSWERS-
Chromatin, nucleolus, and nuclear envelope
