1. A community health nurse is implementing a primary prevention strategy.
Which intervention best exemplifies this level of prevention?
A) Providing influenza vaccinations at a community health fair
B) Conducting blood pressure screenings at a senior center
C) Teaching a diabetes self-management class
D) Referring a client with depression to a mental health counselor
Correct Answer: Providing influenza vaccinations at a community health fair
Rationale: Primary prevention aims to prevent disease before it occurs.
Vaccinations are a classic primary prevention strategy. Screenings are
secondary prevention, disease management is tertiary, and mental health
referral is also tertiary prevention.
2. A public health nurse is applying the core functions of public health. Which
activity best represents the function of assurance?
A) Conducting a community health needs assessment
B) Analyzing morbidity and mortality data to identify trends
C) Ensuring that a local health department has adequate staffing and
resources
D) Developing a policy to reduce tobacco use in public spaces
Correct Answer: Ensuring that a local health department has adequate
staffing and resources
Rationale: The three core functions of public health are assessment, policy
development, and assurance. Assurance involves ensuring that necessary
health services are available and accessible to the community. Assessment
,involves data collection and analysis, and policy development involves
creating policies.
3. An epidemiologist is investigating an outbreak of foodborne illness at a
community picnic. Which measure is most useful for determining the speed
at which the disease is spreading?
A) Prevalence rate
B) Attack rate
C) Incidence rate
D) Case fatality rate
Correct Answer: Attack rate
Rationale: Attack rate is the proportion of people who become ill in a
population exposed to a risk factor over a specific period. It is useful for
measuring the speed and extent of spread in an outbreak. Prevalence
measures existing cases, incidence measures new cases over time, and case
fatality measures deaths among cases.
4. A community health nurse is using the epidemiological triad to analyze the
spread of a disease. Which component of the triad represents the organism
or factor that causes the disease?
A) Host
B) Environment
C) Agent
D) Vector
Correct Answer: Agent
,Rationale: The epidemiological triad consists of agent, host, and
environment. The agent is the organism or factor that causes the disease
(e.g., bacteria, virus). The host is the person affected, the environment is the
external conditions, and the vector is the organism that transmits the agent.
5. A nurse is calculating the incidence rate of a disease in a community.
Which formula should the nurse use?
A) Number of new cases / Population at risk × 1,000
B) Number of existing cases / Total population × 1,000
C) Number of deaths from disease / Number of cases × 100
D) Number of cases / Population exposed × 100
Correct Answer: Number of new cases / Population at risk × 1,000
Rationale: Incidence rate measures the number of new cases of a disease in
a population at risk over a specific time period. Prevalence measures existing
cases, case fatality measures deaths among cases, and attack rate measures
the proportion of exposed people who become ill.
6. A community health nurse is conducting a community assessment. Which
source of data is considered primary data?
A) Census data
B) Vital statistics reports
C) Surveys and interviews with community members
D) Hospital discharge data
Correct Answer: Surveys and interviews with community members
Rationale: Primary data are collected directly from the source, such as
through surveys, interviews, and focus groups. Secondary data are existing
, data collected by others, such as census data, vital statistics, and hospital
discharge data.
7. A nurse is evaluating a community health program. Which outcome
measure is most indicative of the program's effectiveness?
A) Number of participants who attended the program
B) Change in health behaviors or health status of participants
C) Cost of the program per participant
D) Number of staff hours required to implement the program
Correct Answer: Change in health behaviors or health status of participants
Rationale: Outcome evaluation measures the effectiveness of a program by
assessing changes in health behaviors or health status. Attendance, cost,
and staff hours are process measures that do not directly indicate
effectiveness.
8. A community health nurse is working with a population that has a high
rate of obesity. Which level of prevention is the nurse implementing when
counseling individuals about healthy eating and exercise?
A) Primary prevention
B) Secondary prevention
C) Tertiary prevention
D) Primordial prevention
Correct Answer: Primary prevention
Rationale: Counseling individuals about healthy eating and exercise to
prevent obesity is an example of primary prevention, which aims to prevent
