Question 1
A public health nurse is conducting a community assessment in a county
with increasing rates of uncontrolled hypertension. Which intervention
best reflects the primary prevention level?
A. Referring clients with blood pressure readings above 160/100 mm Hg
to a primary care provider
B. Providing rehabilitation services to clients who experienced strokes
C. Conducting community blood pressure screenings and identifying
individuals at risk
D. Teaching clients with diagnosed hypertension how to prevent renal
complications
Answer: C. Conducting community blood pressure screenings and
identifying individuals at risk
Rationale: Screening is generally considered secondary prevention
because it aims to detect disease early, often before symptoms occur.
Primary prevention would focus on preventing hypertension itself
through interventions such as sodium reduction, physical activity,
weight management, and health education. Rehabilitation after stroke
represents tertiary prevention. Therefore, although screening is an
important public health activity, option C is technically secondary
prevention.

,Question 2
A public health nurse is planning an intervention to reduce childhood
obesity in a community. Which intervention represents primary
prevention?
A. Referring children with obesity to a pediatric endocrinologist
B. Providing nutrition and physical-activity education to all elementary
school students
C. Screening children for hypertension associated with obesity
D. Providing physical therapy to children with obesity-related
musculoskeletal problems
Answer: B. Providing nutrition and physical-activity education to
all elementary school students
Rationale: Primary prevention attempts to prevent disease or injury
before it develops. Teaching healthy eating and physical activity to an
entire population can reduce obesity risk. Screening for hypertension
is secondary prevention, while specialty treatment and rehabilitation
are tertiary interventions.
Question 3
A public health nurse is investigating an outbreak of acute gastroenteritis
in a community. Several residents who attended the same picnic
developed vomiting and diarrhea within 24 hours. What should the nurse
do first?
A. Immediately close the community food establishment
B. Begin systematic collection of epidemiologic information
C. Administer antibiotics to all individuals who attended the picnic
D. Notify every household in the county that an outbreak has occurred
Answer: B. Begin systematic collection of epidemiologic information
Rationale: The first steps in outbreak investigation include verifying
the diagnosis and existence of an outbreak, establishing a case
2
,definition, identifying cases, and collecting information about time,
place, person, exposures, and symptoms. Premature closure of an
establishment or mass treatment without adequate evidence may be
inappropriate.
Question 4
A public health nurse develops a case definition during an outbreak
investigation. Which statement best describes a case definition?
A. A list of medications used to treat the disease
B. A standardized set of clinical and/or epidemiologic criteria used to
identify cases
C. A legal document identifying individuals responsible for the outbreak
D. A laboratory test that confirms every suspected case
Answer: B. A standardized set of clinical and/or epidemiologic
criteria used to identify cases
Rationale: A case definition establishes consistent criteria for
determining whether an individual should be classified as a suspected,
probable, or confirmed case. It allows investigators to systematically
identify and count cases during an outbreak.
Question 5
A nurse is teaching residents about herd immunity. Which statement by
a resident demonstrates correct understanding?
A. “Herd immunity means that every individual in the community is
vaccinated.”
B. “Herd immunity can reduce transmission when enough people are
immune to an infectious disease.”
C. “Herd immunity eliminates the need for vaccination.”
D. “Herd immunity occurs only after everyone has been infected.”
Answer: B. “Herd immunity can reduce transmission when enough
people are immune to an infectious disease.”
3
, Rationale: Herd immunity occurs when a sufficiently high proportion
of a population is immune, reducing the likelihood that an infectious
agent will spread. Vaccination is an important method for achieving
population immunity without requiring people to experience the
disease itself.
Question 6
A public health nurse is conducting contact tracing for a person
diagnosed with an infectious disease. What is the primary purpose of
contact tracing?
A. To determine whether the index patient should be hospitalized
B. To identify individuals who may have been exposed and facilitate
appropriate intervention
C. To punish individuals who failed to follow public health
recommendations
D. To determine the financial cost of the outbreak
Answer: B. To identify individuals who may have been exposed and
facilitate appropriate intervention
Rationale: Contact tracing identifies people who may have been
exposed to an infectious disease so they can receive appropriate
testing, monitoring, prophylaxis, treatment, education, or isolation
instructions when indicated. It is a disease-control strategy rather than
a punitive process.
Question 7
A public health nurse is evaluating a community tuberculosis-control
program. Which activity is most appropriate for preventing
transmission?
A. Encouraging clients to discontinue treatment when symptoms
disappear
B. Monitoring adherence to prescribed tuberculosis treatment
