1. A public health nurse is participating in a disaster preparedness planning committee.
Which of the following roles should the nurse include as part of the public health response
team during the mitigation phase? (Select All That Apply)
A. Performing vulnerability assessments to identify at-risk populations.
B. Providing immunizations to victims in temporary shelters.
C. Developing building codes to prevent structural damage during floods.
D. Conducting community education on disaster kits and family plans.
E. Advocating for land-use legislation to prevent building in high-risk zones.
F. Coordinating mental health services for first responders post-event.
Correct Answer: A, C, E
Explanation: Mitigation involves activities to prevent a disaster or reduce the damaging
effects of unavoidable hazards. The public health nurse contributes by identifying risks
through vulnerability assessments and advocating for policies like land-use legislation or
building codes. Education and immunizations are typically part of preparedness and
response, while mental health coordination is often categorized under recovery.
,2. A nurse is assessing a child who has been exposed to high levels of lead in the home. Which
of the following findings should the nurse prioritize?
A. Hyperactivity and distractibility
B. Delayed cognitive development
C. Abdominal pain and constipation
D. Pallor and fatigue due to anemia
Correct Answer: B
Explanation: Lead poisoning has profound effects on the developing nervous system of
children. Delayed cognitive development and intellectual disabilities are serious long-term
consequences that require immediate intervention and environmental remediation. While
gastrointestinal symptoms and anemia occur, the neurologic impact is the most critical
priority for pediatric population health outcomes.
3. In the event of a mass casualty incident, a nurse is using the START triage system. The
nurse identifies a victim who is breathing at 32 breaths/min, has a capillary refill of 3 seconds,
and is unable to follow simple commands. How should this victim be tagged?
A. Green (Minor)
B. Yellow (Delayed)
C. Red (Immediate)
D. Black (Expectant)
,Correct Answer: C
Explanation: The START triage system uses respirations, perfusion, and mental status
(RPM) to categorize victims. A respiratory rate over 30, capillary refill over 2 seconds, or
the inability to follow commands indicates a Red tag (Immediate). This patient meets all
three criteria, necessitating immediate medical attention to stabilize life-threatening
conditions.
4. A community health nurse is calculating the prevalence rate of Type 2 Diabetes in a specific
county. Which of the following data points is required for this calculation?
A. The total number of existing cases at a specific point in time.
B. The number of new cases diagnosed within the last calendar year.
C. The number of deaths attributed to diabetes during the study period.
D. The duration of the illness from onset to recovery or death.
Correct Answer: A
Explanation: Prevalence refers to the total number of all existing cases of a disease in a
population at a given point in time. Incidence, by contrast, only counts new cases appearing
during a specific timeframe. Prevalence is used by public health officials to determine the
burden of chronic diseases on community resources.
5. An occupational health nurse is implementing primary prevention strategies to reduce
workplace injuries. Which of the following actions should the nurse take?
A. Conducting physical therapy for workers with repetitive strain injuries.
, B. Teaching proper lifting techniques to warehouse staff.
C. Screening all employees for hearing loss due to high noise levels.
D. Monitoring lead levels in the blood of factory workers.
Correct Answer: B
Explanation: Primary prevention focuses on preventing the initial occurrence of a disease
or injury. Teaching proper body mechanics and lifting techniques reduces the risk of injury
before it happens. Screening and monitoring are secondary prevention, while physical
therapy is tertiary prevention.
6. A public health nurse is reviewing the ‘Healthy People 2030’ objectives. Which of the
following is considered a social determinant of health (SDOH)? (Select All That Apply)
A. Access to nutritious food and grocery stores.
B. Genetic predisposition to heart disease.
C. Quality of housing and neighborhood safety.
D. Language and literacy skills.
E. Personal lifestyle choices regarding exercise.
Correct Answer: A, C, D
Explanation: Social determinants of health are the conditions in the environments where
people are born, live, learn, work, and age. Access to healthy food, housing quality, and
literacy are all systemic environmental factors that influence health outcomes. Genetics and
