1. A community health nurse is calculating the incidence rate of a new
respiratory illness. There were 50 new cases in a population of 10,000 people
over one year. What is the incidence rate per 1,000 population?
• A. 2 per 1,000
• B. 5 per 1,000
• C. 10 per 1,000
• D. 50 per 1,000
Correct Answer: B. The incidence rate is calculated as (number of new cases /
total population at risk) × 1,000. (,000) × 1,000 = 5 per 1,000.
2. A nurse is reviewing data for a county and finds 200 existing cases of diabetes
out of a population of 50,000. Which measure is the nurse calculating?
• A. Incidence rate
• B. Mortality rate
• C. Prevalence rate
• D. Attack rate
Correct Answer: C. Prevalence rate measures all existing cases (both new and old)
of a disease in a population at a given time. It is calculated as (total existing cases
/ total population) × 1,000.
3. A nurse is educating a community group about the chain of infection. Which
link would the nurse identify as the focus for a client with a new diagnosis of
tuberculosis?
• A. Reservoir
• B. Portal of exit
• C. Susceptible host
, • D. Mode of transmission
Correct Answer: C. The susceptible host is the person who is at risk for infection.
In this scenario, the client with a new diagnosis is the susceptible host who has
acquired the infection.
4. A community health nurse is conducting a screening for hypertension at a
local health fair. This activity is an example of which level of prevention?
• A. Primary prevention
• B. Secondary prevention
• C. Tertiary prevention
• D. Primordial prevention
Correct Answer: B. Secondary prevention focuses on early detection and
treatment of disease through screening activities, such as checking blood
pressure.
5. A nurse provides a community education session on smoking cessation to
high school students. This is an example of which level of prevention?
• A. Primary prevention
• B. Secondary prevention
• C. Tertiary prevention
• D. Quaternary prevention
Correct Answer: A. Primary prevention aims to prevent disease or injury before it
occurs. This is done by preventing exposure to hazards, altering unhealthy
behaviors, and increasing resistance to disease.
6. A client with a history of a stroke is receiving physical therapy to regain
mobility. This is an example of which level of prevention?
• A. Primary prevention
• B. Secondary prevention
• C. Tertiary prevention
, • D. Health promotion
Correct Answer: C. Tertiary prevention aims to soften the impact of an ongoing
illness or injury that has lasting effects. This is done by helping people manage
long-term, complex health problems and injuries to improve as much as possible
their ability to function, their quality of life, and their life expectancy.
7. A nurse is investigating a foodborne illness outbreak. Which epidemiological
term describes the number of new cases in a specific population during a
specific time?
• A. Prevalence
• B. Incidence
• C. Morbidity
• D. Mortality
Correct Answer: B. Incidence refers to the number of new cases of a disease that
occur in a population during a specified period.
8. A public health nurse is conducting a community assessment. Which of the
following is the primary reason for this assessment?
• A. To identify individual health needs
• B. To comply with state regulations
• C. To determine the community's health status and needs
• D. To evaluate the effectiveness of existing programs
Correct Answer: C. A community assessment is the cornerstone of community
health nursing. Its primary purpose is to systematically collect and analyze data to
understand the health status, needs, and resources of a population.
9. A nurse is using the epidemiological triangle to analyze a communicable
disease outbreak. Which components should the nurse include?
• A. Agent, host, environment
• B. Host, agent, vector
, • C. Environment, host, reservoir
• D. Agent, environment, vector
Correct Answer: A. The epidemiological triangle is a traditional model for
infectious disease causation and includes three components: an external agent, a
susceptible host, and an environment that brings the host and agent together.
10. A nurse is planning a community health program. What is the most
important first step in the program planning process?
• A. Developing goals and objectives
• B. Identifying available resources
• C. Performing a needs assessment
• D. Implementing the intervention
Correct Answer: C. The nursing process and program planning both begin with
assessment. A needs assessment identifies the health problems and strengths of
the community, which is essential for effective planning.
11. A community health nurse is educating a group about the importance of
immunizations. This activity is aimed at breaking the chain of infection at which
link?
• A. Reservoir
• B. Portal of entry
• C. Susceptible host
• D. Mode of transmission
Correct Answer: C. Immunizations work by increasing a person's resistance to a
specific disease, thereby making them a less susceptible host.
12. A nurse is calculating the prevalence of asthma in a school. There are 20
students with asthma out of a total of 500 students. What is the prevalence rate
per 100 students?
• A. 2 per 100
