1. A community health nurse is planning a primary prevention strategy for a
local community. Which intervention is an example of primary prevention?
A) Providing influenza vaccinations at a community clinic
B) Conducting blood pressure screenings at a senior center
C) Teaching a diabetes management class for clients with type 2 diabetes
D) Referring a client with depression to a mental health counselor
Correct Answer: Providing influenza vaccinations at a community clinic
Rationale: Primary prevention aims to prevent disease before it occurs.
Vaccinations are a classic example of primary prevention. Screenings are
secondary prevention, diabetes management is tertiary prevention, and
mental health referral is also tertiary prevention.
2. A public health nurse is applying the core functions of public health. Which
activity represents the core function of assurance?
A) Conducting a community health needs assessment
B) Investigating a foodborne illness outbreak
C) Ensuring that a local health department has adequate staffing to provide
services
D) Analyzing morbidity and mortality data to identify trends
Correct Answer: Ensuring that a local health department has adequate
staffing to provide services
Rationale: The 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 policy development involves creating policies.
3. An epidemiologist is investigating an outbreak of a communicable disease.
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 agent 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 public 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
