1. A community health nurse is planning educational programs for a local high school. Which
of the following activities should be categorized as primary prevention? (Select All That
Apply)
A. Teaching students about the dangers of vaping and tobacco use
B. Providing influenza vaccinations to faculty and students
C. Screening students for scoliosis during physical education classes
D. Discussing healthy nutrition and exercise to prevent obesity
E. Administering insulin to a student diagnosed with Type 1 diabetes
F. Teaching prenatal classes to pregnant adolescents
Correct Answer: A, B, D
Explanation: Primary prevention focuses on preventing the occurrence of a disease or
injury before it happens. In this scenario, tobacco education, vaccinations, and nutrition
counseling are all proactive measures aimed at healthy populations. Screening is secondary
prevention, while insulin administration and prenatal care for existing pregnancies are
considered tertiary or secondary interventions.
,2. A nurse is conducting a windshield survey of a new neighborhood. Which of the following
observations would be most useful in assessing the community’s environmental health?
A. The number of religious institutions in the area
B. Presence of industrial plants and smoke stack emissions
C. Availability of public transportation and sidewalks
D. The age and condition of housing structures
Correct Answer: B
Explanation: Environmental health assessments focus on physical factors in the
environment that can impact human health. Observing industrial plants and emissions
directly relates to air quality and potential toxic exposure within the community. While
transportation and housing are important social determinants, they do not specifically
address environmental hazards as directly as industrial pollution.
3. An occupational health nurse is using the ‘I PREPARE’ mnemonic to assess a patient’s
environmental exposure. What does the ‘P’ in the mnemonic represent?
A. Policy updates
B. Present work
C. Past medical history
D. Primary prevention
Correct Answer: B
,Explanation: The ‘I PREPARE’ mnemonic is a systematic tool used by nurses to identify
environmental exposure history. The ‘P’ stands for ‘Present work,’ which involves asking
about current workplace hazards, chemical exposures, or protective equipment use. This
ensures the nurse gathers comprehensive data regarding the patient’s daily environment.
4. A public health nurse is analyzing the prevalence of a specific disease in the county. How is
prevalence defined in epidemiology?
A. The number of new cases of a disease in a population over a specific time
B. The total number of existing cases of a disease in a population at a given time
C. The number of deaths resulting from a specific disease in one year
D. The ratio of people who are sick compared to the total population
Correct Answer: B
Explanation: Prevalence refers to the total number of cases, both new and pre-existing,
within a population at a specific point in time. This differs from incidence, which focuses
solely on new cases occurring within a certain timeframe. Understanding prevalence helps
health officials allocate resources for chronic disease management and long-term care.
5. Which of the following populations are considered ‘vulnerable’ and are at higher risk for
health disparities? (Select All That Apply)
A. Individuals experiencing homelessness
B. Migrant farm workers
C. Pregnant women living in rural areas
, D. Full-time employed individuals with private insurance
E. Veterans with post-traumatic stress disorder
F. Refugees fleeing political conflict
Correct Answer: A, B, C, E, F
Explanation: Vulnerable populations include groups that are at higher risk for poor health
outcomes due to social, economic, or environmental barriers. Homeless individuals,
migrant workers, rural residents, and refugees often lack access to consistent healthcare
and face unique stressors. Veterans are also considered vulnerable due to specific physical
and mental health risks associated with service.
6. A nurse is caring for a migrant farm worker who presents with respiratory distress and skin
rashes. Which environmental factor is the most likely cause?
A. Exposure to lead-based paint in old housing
B. Inhalation of urban smog and carbon monoxide
C. Lack of access to clean drinking water
D. Chronic exposure to pesticides and herbicides
Correct Answer: D
Explanation: Migrant farm workers are at high risk for pesticide exposure, which can lead
to acute and chronic respiratory and dermatological issues. These workers often handle
