1. A community health nurse is reviewing the core functions of public health. Which activities
should the nurse identify as part of the ‘Assessment’ core function? (Select all that apply.)
A. Monitoring health status to identify community health problems
B. Diagnosing and investigating health problems and hazards in the community
C. Developing policies and plans that support individual and community health efforts
D. Enforcing laws and regulations that protect health and ensure safety
E. Evaluating effectiveness, accessibility, and quality of personal and population-based
health services
F. Researching for new insights and innovative solutions to health problems
Correct Answer: A, B
Explanation: The core function of Assessment includes monitoring health status and
diagnosing/investigating health hazards. Policy Development involves creating plans and
laws, while Assurance involves enforcing laws and evaluating services. Understanding
these distinctions is vital for public health nurses to prioritize activities that collect and
analyze data about the community’s health.
,2. Which of the following interventions describes a nurse working in a community-oriented
nursing role?
A. Developing a program to reduce the incidence of childhood obesity across the school
district
B. Providing wound care to a patient in their home following a surgery
C. Administering IV antibiotics to a client at an outpatient infusion center
D. Teaching a diabetic patient how to self-administer insulin in a clinic setting
Correct Answer: A
Explanation: Community-oriented nursing focuses on the health of the community or a
population as a whole. This differs from community-based nursing, which focuses on
providing acute or chronic care to individuals and families within the community.
Developing a district-wide obesity program addresses the population level, fitting the
definition of community-oriented practice.
3. A nurse is conducting a screening for hypertension at a local community center. This
activity represents which level of prevention?
A. Secondary prevention
B. Primary prevention
C. Tertiary prevention
D. Quaternary prevention
, Correct Answer: A
Explanation: Screening activities are classified as secondary prevention because they aim
to detect disease in its early stages before symptoms appear. Primary prevention focuses
on preventing the disease from occurring, while tertiary prevention focuses on
rehabilitation and management of established disease. Identifying hypertension early
allows for intervention to prevent complications like stroke or heart disease.
4. In the epidemiological triangle, which of the following would be considered the ‘host’
factor? (Select all that apply.)
A. Genetic susceptibility
B. Bacteria or viruses
C. Age and sex
D. Climate and weather
E. Immunological status
Correct Answer: A, C, E
Explanation: Host factors are intrinsic factors that influence an individual’s susceptibility
or response to an agent. These include genetics, age, sex, and immunological status.
Bacteria and viruses are ‘agents,’ and climate is an ‘environmental’ factor.
5. The nurse is analyzing the incidence of a disease in a specific county. How is the incidence
rate calculated?
A. The number of all existing cases of a disease in a population at a given time
