NR503 FINAL EXAM STUDY GUIDE
Review primary, secondary, & tertiary prevention practices, screening, vulnerable populations, and the role of the nurse practitioner.
Week 5 (Ch. 2)
1. Discriminate populations at risk for development of chronic health conditions while associating the role of the Advanced
Practice Nurse in levels of promotion.
Common risk factors: unhealthy diet, physical inactivity, and tobacco use
Childhood risk: There is now extensive evidence from many countries that conditions before birth and in early childhood
influence health in adult life. For example, low birth weight is now known to be associated with increased rates of high blood
pressure, heart disease, stroke and diabetes.
Risk accumulation: Ageing is an important marker of the accumulation of modifiable risks for chronic disease: the impact of risk
factors increases over the life course.
Underlying determinants: The underlying determinants of chronic diseases are a reflection of the major forces driving social,
economic and cultural change – globalization, urbanization, population ageing, and the general policy environment.
Poverty: Chronic diseases and poverty are interconnected in a vicious circle. At the same time, poverty and worsening of already
existing poverty are caused by chronic diseases. The poor are more vulnerable for several reasons, including greater exposure to
risks and decreased access to health services. Psychosocial stress also plays a role.
Preventative health actions are often categorized in three levels:
● Primary prevention - aims to prevent disease or injury before it ever occurs.
▪ This is done by preventing exposures to hazards that cause disease or injury, altering unhealthy
or unsafe behaviors that can lead to disease or injury, and increasing resistance to disease or
injury should exposure occur.
▪ Nurses play the part of educators that offer information and counseling to communities
and populations that encourage positive health behaviors
▪ Examples include:
● legislation and enforcement to ban or control the use of hazardous products (e.g.
asbestos) or to mandate safe and healthy practices (e.g. use of seatbelts and bike
helmets)
● education about healthy and safe habits (e.g. eating well, exercising regularly,
not smoking)
● immunization against infectious diseases.
● Secondary prevention - aims to reduce the impact of a disease or injury that has already occurred
▪ This is done by detecting and treating disease or injury as soon as possible to halt or slow its
progress, encouraging personal strategies to prevent reinjury or recurrence, and
implementing programs to return people to their original health and function to prevent long-
term problems.
▪ Nurses work with these patients to reduce and manage controllable risks, modifying the
individuals’ lifestyle choices and using early detection methods to catch diseases in their
beginning stages when treatment may be more effective.
▪ Examples include:
● regular exams and screening tests to detect disease in its earliest stages
(e.g. mammograms to detect breast cancer)
● daily, low-dose aspirins and/or diet and exercise programs to prevent further heart
attacks or strokes
● suitably modified work so injured or ill workers can return safely to their jobs.
● Tertiary prevention - aims to soften the impact of an ongoing illness or injury that has lasting effects
▪ This is done by helping people manage long-term, often-complex health problems and injuries
(e.g. chronic diseases, permanent impairments) in order to improve as much as possible their
ability to function, their quality of life and their life expectancy.
▪ Nurses are tasked with helping individuals execute a care plan and make any additional
behavior modifications necessary to improve conditions
▪ Examples include:

● cardiac or stroke rehabilitation programs, chronic disease management programs (e.g.
for diabetes, arthritis, depression, etc.)
● support groups that allow members to share strategies for living well
● vocational rehabilitation programs to retrain workers for new jobs when they have
recovered as much as possible.

Members of minorities are overrepresented on the low tiers of the socioeconomic ladder. Poor economic achievement is also a
common characteristic among populations at risk, such as the homeless, migrant workers, and refugees. However, the APN should be
able to distinguish between cultural and socioeconomic class issues and not interpret behavior as having a cultural origin when the
fact is based on socioeconomic class. A good resource for APNs is the Cross-Cultural Health Care Program (CCHCP), which has a
plethora of materials to improve cultural competency among healthcare providers, including a training program for healthcare
providers. In order to provide appropriate healthcare interventions, culture and all its variants must be addressed.
(p28)APRNs may be able to access health information needed by working together with other sectors outside of health, such as
housing, labor, education, and community-based or faith-based organizations that offer services to immigrant communities. This
involves the collection, documentation, and use of data that can be used to monitor health inequalities in exposures, opportunities, and
outcomes. Examples of social determinants that are related to health inequalities include poverty, educational level, racism, income,
and poor housing. These inequalities can lead to
poor quality of life, poor self-rated health, multiple morbidities, limited access to resources, premature death, and unnecessary risks
and vulnerabilities.
(p25) APRNs can best determine the effectiveness of an intervention and long-term impact by focusing on an accurate assessment and
interpretation of data that are generated or collected using individual, population, and community health indicators.
(p27)APRNs can work in partnership with community members to identify what community members see as relevant and important,
build social capital, use outcome data to advocate for changes in policy, and then continue to work in partnership to identify strategies
to intervene, monitor,and improve those outcomes
(p40-41)APRNs have numerous resources they can access to improve quality and timely access to quality healthcare and decrease
health disparities. The National Partnership for Action (NPA) to End Health Disparities ( minorityhealth.hhs.gov/npa) was started by
the Office of Minority Health
to mobilize individuals and groups to work to improve quality and eliminate health disparities. The National Priorities includes key
private and public stakeholders who have agreed to work on major health priorities of patients and families, palliative and end-of-life
care, care coordination, patient safety, and population health. The Quality Alliance Steering Committee is another partnership of
healthcare leaders who work to improve healthcare quality and costs. Various strategies to bridge the gaps in healthcare quality are
available at the national level and may be applied or considered at the state, regional, or local level in collaboration with stakeholders
as a means of decreasing health disparities.
(p43) APRNs are better prepared to develop effective interventions to eliminate or reduce health disparities. Such strategies may
include advocating better health insurance coverage
for poor and immigrant populations; ensuring that sufficient services exist in
underserved areas; assessing the interaction among social environments, genetics,
and population health; encouraging minority participation in research studies with community-based participatory research and
specifically with practice-based research networks; using linguistically and culturally appropriate communication and written
handouts; promoting and facilitating community partnerships; and implementing strategies to encourage people from minority
populations to become healthcare professionals
2. Compare and contrast variables that differentiate those categorized at being at risk for marginalization of health care.
Definition: when an individual or group is put into a position of less power or isolation within society because of discrimination Limits
their opportunities and means for survival. When an individual is marginalized, they are unable to access the same services and
resources as other people and it becomes very difficult to have a voice in society.
Marginalization – major cause of vulnerability, which refers to exposure to a range of possible harms, and being unable to deal with
them adequately.
● Variables: social class, race, homelessness, substance abuse, prison/offending, mental health problems, HIV positive
● Women are more likely to be marginalized than men, because of their gender. This is evident through the social,
economic, and power imbalances that exist between men and women. For example, more women than men live
in poverty, and men continue to have more secure, full-time jobs and higher income than their female
counterparts.
