Community Health Q&A | Community Health
1. A community health nurse is reviewing the levels of disease prevention.
Which of the following activities is an example of primary prevention?
A) Screening for hypertension at a community health fair
B) Providing case management for a client with diabetes
C) Teaching a class on healthy eating and physical activity
D) Administering antibiotics to a client with an infection
Correct Answer: Teaching a class on healthy eating and physical activity
Rationale: Primary prevention aims to prevent disease or injury before it
occurs. Health education on lifestyle modifications is a classic example.
Screening is secondary prevention, and case management and treatment are
tertiary prevention.
2. Which of the following is a key characteristic of a community health
nursing approach?
A) Focus on illness care for individuals and families
B) Emphasis on health protection, promotion, and disease prevention
C) Practice primarily in acute care hospital settings
D) Orientation toward individual bedside care
Correct Answer: Emphasis on health protection, health promotion, and
disease prevention
Rationale: Community health nursing is population-focused and emphasizes
health protection, health promotion, and disease prevention. It is distinct
from community-based nursing, which focuses on acute or chronic illness
care for individuals and families.
,3. According to the principles of epidemiology, what is the definition of
"incidence"?
A) The total number of cases of a disease in a population at a given time
B) The number of new cases of a disease in a population over a specific
period
C) The number of deaths from a disease in a population
D) The number of people at risk for a disease
Correct Answer: The number of new cases of a disease in a population over a
specific period
Rationale: Incidence measures the rate at which new cases of a disease
occur in a population. Prevalence is the total number of cases (both new and
existing) at a given time.
4. A nurse is using the epidemiological triangle to understand the spread of a
communicable disease. Which of the following are the primary components
of this model?
A) Host, Agent, and Environment
B) Host, Vector, and Time
C) Agent, Environment, and Socioeconomic factors
D) Host, Time, and Environment
Correct Answer: Host, Agent, and Environment
Rationale: The epidemiological triangle is a model that describes the
interaction between three primary factors in disease transmission: the host
(the person affected), the agent (the cause of the disease), and the
environment (the external factors that allow the disease to spread).
,5. Which of the following is a social determinant of health that a community
health nurse should assess?
A) Genetic predisposition to disease
B) Access to nutritious food
C) Blood type
D) Allergies
Correct Answer: Access to nutritious food
Rationale: Social determinants of health are the conditions in which people
are born, grow, live, work, and age. Access to nutritious food is a key social
determinant. Genetics, blood type, and allergies are biological factors.
6. A nurse is working with a community to reduce the incidence of teen
pregnancy. Which of the following strategies is most appropriate?
A) Providing sex education in schools
B) Increasing access to contraception
C) Promoting abstinence
D) All of the above
Correct Answer: All of the above
Rationale: A comprehensive approach to reducing teen pregnancy includes
sex education, increasing access to contraception, and promoting
abstinence. This multi-pronged strategy addresses the various factors that
contribute to teen pregnancy.
, 7. Which federal agency is primarily charged with providing assistance to
communities hit by natural disasters?
A) Centers for Disease Control and Prevention (CDC)
B) Federal Emergency Management Agency (FEMA)
C) National Institutes of Health (NIH)
D) World Health Organization (WHO)
Correct Answer: Federal Emergency Management Agency (FEMA)
Rationale: FEMA is the primary federal agency for disaster assistance,
supporting citizens and first responders to prepare for, protect against,
respond to, recover from, and mitigate all hazards.
8. A community health nurse is using the "community as partner" model.
Which of the following best describes this approach?
A) The nurse is the expert who tells the community what to do
B) The nurse and the community work together as equal partners
C) The community is passive and receives services from the nurse
D) The nurse only provides direct care to individuals
Correct Answer: The nurse and the community work together as equal
partners
Rationale: The "community as partner" model emphasizes collaboration
between the nurse and the community as equal partners, respecting the
community's strengths and resources and empowering community members
to take an active role in improving their health.
