1. A community health nurse is conducting a vaccination clinic for seasonal influenza. Which
level of prevention does this activity represent?
A. Secondary prevention
B. Tertiary prevention
C. Quaternary prevention
D. Primary prevention
Correct Answer: D
Explanation: Primary prevention aims to prevent the onset of disease or injury before it
occurs. Immunizations are a classic example of primary prevention as they provide
immunity to a population before exposure. This intervention reduces the overall burden of
disease within the community by preventing transmission chains.
2. Which of the following factors are considered social determinants of health (SDOH) that a
nurse must assess during a community health profile? (Select All That Apply)
A. Economic stability and income levels
B. Access to quality education
,C. Individual genetic predispositions
D. Neighborhood and built environment
E. Social and community context
F. Health care access and quality
Correct Answer: A, B, D, E, F
Explanation: Social determinants of health are the conditions in the environments where
people are born, live, learn, work, play, worship, and age. According to Healthy People
2030, these include economic stability, education access, health care access, neighborhood
environment, and social context. While genetics (Choice C) affects health, it is considered a
biological factor rather than a social determinant.
3. The public health nurse is analyzing the number of new cases of syphilis reported in the
county over the last six months. Which epidemiological measure is the nurse evaluating?
A. Incidence rate
B. Prevalence rate
C. Attack rate
D. Case fatality rate
Correct Answer: A
Explanation: Incidence refers specifically to the number of new cases of a disease
occurring in a population during a specified period. This differs from prevalence, which
,counts all existing cases (both old and new) at a specific point in time. Monitoring incidence
helps nurses understand the rate of spread and the effectiveness of current prevention
programs.
4. A nurse is investigating an outbreak of foodborne illness at a local school. Using the
epidemiological triangle, the nurse identifies the contaminated lettuce as which component?
A. The Environment
B. The Agent
C. The Host
D. The Vector
Correct Answer: A
Explanation: The epidemiological triangle consists of the host, the agent, and the
environment. In this scenario, the contaminated lettuce serves as the environment or the
medium that allows the agent to reach the host. The agent would be the specific bacteria or
virus on the lettuce, and the students are the hosts.
5. A nurse working in a rural community identifies several barriers to health care access for
the local population. Which factors are likely contributing to this disparity? (Select All That
Apply)
A. Long travel distances to specialty providers
B. Lack of reliable public transportation
C. Higher proportions of uninsured residents
, D. An overabundance of healthcare specialists
E. Limited access to high-speed internet for telehealth
Correct Answer: A, B, C, E
Explanation: Rural populations often face unique challenges including geographic
isolation and lack of transport. Economic factors such as higher poverty rates and lower
insurance coverage also impede access. Telehealth is a potential solution, but it is often
limited by poor broadband infrastructure in remote areas.
6. Which intervention by the nurse is an example of secondary prevention?
A. Teaching a class on healthy cooking for heart health
B. Assisting a patient with stroke rehabilitation
C. Providing skin cancer screenings at a local beach
D. Administering a tetanus booster to an injured worker
Correct Answer: C
Explanation: Secondary prevention focuses on early detection and prompt intervention to
limit the severity of a disease. Screenings for cancer, hypertension, or diabetes are hallmark
secondary prevention activities. These actions occur after the disease process has begun
but before clinical symptoms are significant.
