NR 503 Midterm Exam Question and
Answer (2026) | A+ Verified | Accurate
Solutions
• Epidemiology . Answer: is the science of public health
• Population Health . Answer: focuses on risk, data, demographics, and outcomes.
• Outcomes . Answer: is the end result that follows an intervention
• aggregate . Answer: is a defined population.
• community . Answer: is composed of multiple aggregates
• data . Answer: is complied information
• Prevalence . Answer: measures the existence of a disease. Measures the number
of all cases of a disease or attribute in a population at a given time
• Incidence . Answer: measures the appearance of a disease. Measures the
occurrence of new events in a population over a period of time.
• surveillance . Answer: is the collection, analysis, and dissemination of data.
• high-risk . Answer: is an increased chance of poor health outcome.
• Morbidity . Answer: is the presence of illness in a population
• mortality . Answer: is related to the tracking deaths in an aggregate
• vital statistics . Answer: statistics on live births, deaths, fetal deaths, marriages
and divorces.
• cases . Answer: set of criteria used in making a decision as to whether an
individual has a disease or health event of interest
, • Social Justice . Answer: the view that everyone deserves equal rights and
opportunities —this includes the right to good health
• Inter-professional collaboration . Answer: The idea of sharing and implies
collective action oriented toward a common goal, in this case, improving the
quality and safety of patient care. It involves responsibility, accountability,
coordination, communication, cooperation, assertiveness, mutual respect, and
autonomy.
• Healthy People 2020 . Answer: aims to reach four overarching goals: 1.Attain
high-quality, longer lives free of preventable disease, disability, injury, and
premature death, 2. Achieve health equity, eliminate disparities, and improve the
health of all groups 3.Create social and physical environments that promote good
health for all. 4. Promote quality of life, healthy development, and healthy
behaviors across all life stages.
• Determinants of care/health . Answer: The range of personal, social, economic,
and environmental factors that influence health status are known ...
• risk analysis . Answer: the characterization of the potential adverse health effects
of human exposures to environmental hazards
• health disparities . Answer: the difference in health statuses between various
groups (populations).
• Sensitivity . Answer: measures the proportion of actual positives that are
correctly identified as such (e.g., the percentage of sick people who are correctly
identified as having the condition)
• Specificity . Answer: (also called the true negative rate) measures the proportion
of actual negatives that are correctly identified as such (e.g., the percentage of
healthy people who are correctly identified as not having the condition)
• Positive predictive value . Answer: is the probability that subjects with a positive
screening test truly have the disease
• epidemiological triangle . Answer: 1. A traditional model of infectious disease
causation, known as the Epidemiologic Triad is depicted in Figure 2. The triad
consists of an external agent, a host and an environment in which host and agent
are brought together, causing the disease to occur in the host.
