identification
Social determinants of health, health disparities, equity, and vulnerable populations
Health promotion, disease prevention, screening, and risk reduction
Environmental health, sanitation, housing, occupational hazards, and environmental
exposures
Communicable diseases, immunization, outbreak investigation, and infection prevention
Chronic disease management, behavioral health, nutrition, and community-based
interventions
Emergency preparedness, disaster management, triage, and public health response

Community partnerships, health education, cultural competence, ethics, advocacy, and
program evaluation
1. Which statement best describes the primary focus of community health nursing when
compared with traditional acute-care nursing?
A. Providing treatment exclusively to individuals after illness has developed
B. Focusing primarily on hospital-based diagnostic procedures and medication administration
C. Improving the health of populations while addressing individual needs within their
communities
D. Limiting nursing interventions to clients who have established medical diagnoses
Answer: C
Rationale: Community health nursing focuses on population health while still addressing
individual and family needs within the broader community context.
2. What is the primary purpose of conducting a comprehensive community assessment
before developing a population health intervention?
A. To identify community strengths, risks, resources, and health needs that should guide
planning
B. To determine which individual residents require immediate hospitalization
C. To establish the exact number of healthcare providers needed in every facility
D. To replace all existing community programs with newly developed interventions
, Page 3 of 116
Answer: A
Rationale: Assessment identifies population characteristics, health problems, assets, resources,
and environmental factors needed to develop appropriate interventions.
3. Which epidemiological measure describes the number of new cases of a disease
occurring within a specified population during a defined period?
A. Prevalence
B. Incidence
C. Mortality
D. Case-fatality ratio
Answer: B
Rationale: Incidence measures newly occurring cases during a specified period, whereas
prevalence measures existing cases.
4. Why is prevalence particularly useful when public health professionals are planning
services for people living with chronic conditions?
A. It identifies only newly diagnosed individuals during an outbreak
B. It measures the number of deaths attributable to a disease
C. It determines whether a disease is transmitted through direct contact
D. It estimates the total burden of existing disease within a population
, Page 4 of 116
Answer: D
Rationale: Prevalence includes existing cases and therefore helps estimate the overall burden of
chronic diseases requiring ongoing services.
5. A community nurse discovers that a neighborhood has unusually high rates of
uncontrolled hypertension. Which action should occur first?
A. Assess population characteristics, contributing factors, existing resources, and barriers to care
B. Immediately distribute antihypertensive medications to all residents
C. Recommend hospitalization for every resident with elevated blood pressure
D. Begin an exercise program without collecting additional community information
Answer: A
Rationale: A population-focused intervention should begin with assessment rather than
assuming the cause or implementing an unplanned intervention.
6. Which example represents a social determinant of health rather than an individual
biological risk factor?
A. Genetic predisposition to cardiovascular disease
B. Elevated serum cholesterol
C. Lack of reliable transportation to healthcare services
D. Family history of type 2 diabetes
