ANSWERS
g What type of prevention is screening or exams? - Secondary Prevention
Tertiary Prevention - What type of prevention is a cardiac or stroke rehabilitation program?
What prevention attempts to minimize negative effects, prevents further disease or disorder related to
complications, prevent relapse, and restore the highest physical or psychological functioning possible? -
Tertiary Prevention
What prevention emphasizes on early disease detection by screening? - Secondary Prevention
Primary Prevention - What prevention refers to preventing disease before it occurs?
Secondary Prevention - Which type of prevention are these examples of:
-The APN screens all pregnant patients for Hepatitis B, and Group Beta Strep.
-An APN school nurse examines all students for lice at the beginning of the school year.
-Each year the school nurse administers a visual test to all students who do not wear glasses or contacts.
-The APN supervised patients with smallpox who are quarantined.
-Before immigrants are allowed to immigrate to the US, the public health nurse ensures that individuals
have a chest x-ray.
Tertiary Prevention - Which type of prevention are these examples of:
-Mrs. A. goes directly to rehabilitation following a total hip replacement.
-Mr. B. adopts a Health Heart diet to control his high cholesterol.
-14 year old Lindsey Hemoglobin AC1 is within normal limits and is able to decrease her insulin.
-Mrs. Brown, who has been diagnosed with osteoarthritis, is able to maintain normal activity without
pain if she is compliant with her treatment plan.
-Many trauma patients can resume normal activities after rehabilitation.
Primary Prevention - What type of prevention are these examples of:
-The APN teaching students who are not pregnant about birth control and natural family planning
methods.

-The APN is active in his/her professional organization to lobby that pesticides are banned from

How does a provider determine the usefulness, appropriateness, of a screening test? - The target
population needs to be identifiable and accessible and the disease should affect a sufficient number of
people. The screening test should be sensitive enough to detect most cases and be specific enough to
limit the number of false positives. Screening test should be relatively inexpensive, easy to administer,
and have minimal side effects. The validity of the screening test is the ability to accurately identify those
that have the disease.
Where would a NP look to find a screening test? - US Preventive Services Task, Agency for Healthcare
Research and Quality
What determines if a screening test should be used? - Determining if a screening test should be used can
be evaluated by the success of a screening tool. Does the screening tool do what it was intended to do
and reduce the overall mortality, decrease case fatality, increase early detection, reduce complications or
increase quality of life?
Can you explain what "descriptive epidemiology" means? What is the purpose? How is it used? -
Concerned with characterizing the amount and distribution of health and disease within a population.
Through the process of looking at rates, incidence, prevalence, mortality, survival, and prognosis we have
and understanding of a disease and knowledge of how populations differ. Also, what interventions would
be best for who.
How are causation and descriptive epidemiology related, how do they work together to aid evidence-
based care? - Descriptive epidemiology is the first step in any epidemiology investigation or in analyzing
any health problem from a research perspective. Causation is found through further research study to
determine the best interventions in patient care and overall population health. They both work together
to aid evidence-based care by describing patterns of disease in populations and identifying potential risk
factors.
What does "causation" mean? - The relationship between cause and effect
Can you relate causation to primary, secondary and tertiary interventions? - Causation is the cause and
effect relationship in which one variable controls the changes in another variable. Such as smoking
increases risk of lung cancer. Primary intervention would be to eliminate or reduce factors related to the
variable. Such as reducing factors that cause asthma-obesity, pollution, sedentary lifestyle. Secondary
intervention would be early detection of asthma symptoms. Tertiary interventions would be managing
the asthma and stopping the progression of the asthma.
What are the 5W's of descriptive epidemiology: - What = health issue of concern
Who = person
Where = place
