,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.
7. Define epidemiology and name some things that it tracks.:
Epidemiology is the study of disease occurrence. It tracks the health
of a community by tracking age, race, nutritional habits and
locations.
8. What is the difference between incidence and prevalence?:
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.
9. Define mortality and morbidity.: Morbidity is the effect of an
illness on one's life. Mortality statistics deal with the cause of death
in a population.
10. Define primary, secondary, and tertiary prevention and give an
example of each.: Primary prevention is what a person does to
prevent a disease from occurring, ex. eating healthy and exercising.
, Secondary prevention is aiming to detect and treat diseases when they
are either still curable or asymptomatic. ex. pap smear for cervical
cancer
Tertiary prevention is when a disease is diagnosed and clinical
interventions happen to cause further complications. Ex, using
medication to reduce the risk of future heart attacks.
11. Why is evidence-based practice 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.
12. What are the 3 primary structures of the cell?: The
nucleus, cytoplasm, and plasma membrane
13. What is the function of the nucleus?: The nucleus is the
control center for the cell and contains most of the hereditary
material, DNA and RNA.
14. Name 3 structures within the nucleus.: Chromatin,
nucleolus, and nuclear envelope
