1. A community health nurse is conducting an assessment on environmental health risks for
children in an urban housing development. Which factors should the nurse identify as
contributing to increased susceptibility in children? (Select all that apply)
A. Faster respiratory rate leading to higher inhalation of toxins
B. Immature blood-brain barrier
C. Higher metabolic rate and food intake per pound of body weight
D. Lower proximity to ground-level contaminants
E. Developing organ systems that are less able to detoxify substances
F. Frequent hand-to-mouth behaviors
Correct Answer: A, B, C, E, F
Explanation: Children are at higher risk for environmental exposures because their
physiological systems are still developing and they have unique behaviors. Their faster
breathing rates increase the intake of air pollutants, and their immature kidneys and livers
cannot process toxins as efficiently as adults. Hand-to-mouth behavior and crawling
significantly increase their ingestion of dust, lead, and soil-bound chemicals.
,2. A nurse is reviewing the ‘I PREPARE’ mnemonic for assessing environmental health history.
What does the ‘E’ in the mnemonic represent?
A. Education
B. Environment
C. Employment
D. Exposure
Correct Answer: D
Explanation: The ‘I PREPARE’ mnemonic stands for Investigate potential exposures,
Present work, Residence, Environmental concerns, Past work, Activities, Referrals and
resources, and Educate. The first ‘E’ specifically prompts the nurse to ask about
environmental concerns in the current living area. The second ‘E’ at the end stands for
Educate to ensure the patient understands how to mitigate risks.
3. In the context of the Epidemiological Triangle, which factor represents a ‘Host’ in the
transmission of influenza?
A. An unvaccinated healthcare worker
B. Cold, damp winter weather
C. The Influenza A virus
D. Crowded living conditions
Correct Answer: A
,Explanation: The Epidemiological Triangle consists of the agent, the host, and the
environment. The host is the living being that the agent or parasite influences, which in this
case is the human worker. The virus itself is the agent, while weather and crowding
represent the environment.
4. A nurse is evaluating the incidence and prevalence of diabetes in a specific county. The
nurse understands that ‘incidence’ refers to:
A. The total number of cases in the population at a specific point in time.
B. The proportion of the population that has ever been diagnosed with the condition.
C. The ratio of deaths to the total population in one year.
D. The number of new cases of a disease identified during a specific period.
Correct Answer: D
Explanation: Incidence specifically measures the rate at which new cases of a disease
occur within a population over a period of time. It is used to understand the risk of
contracting the disease and the effectiveness of primary prevention strategies. Prevalence,
on the other hand, measures all existing cases (new and old) to determine the total burden
of the disease.
5. Which of the following interventions represents tertiary prevention for a population
affected by chronic obstructive pulmonary disease (COPD)?
A. Smoking cessation programs for teenagers
B. Pulmonary rehabilitation programs for patients with established COPD
, C. Spirometry screening for individuals at high risk for lung disease
D. Immunizing the elderly against pneumococcal pneumonia
Correct Answer: B
Explanation: Tertiary prevention aims to manage and rehabilitate individuals who already
have a chronic disease to prevent further deterioration. Pulmonary rehabilitation helps
maximize function and quality of life for those already diagnosed with COPD. Secondary
prevention would involve screening, while primary prevention involves education and
vaccines to prevent the onset of disease.
6. A community health nurse is planning a health fair. According to the Social Determinants of
Health (SDOH) framework, which areas should the nurse focus on to improve population
outcomes? (Select all that apply)
A. Economic stability
B. Education access and quality
C. Genetics and biological traits
D. Social and community context
E. Neighborhood and built environment
F. Healthcare access and quality
Correct Answer: A, B, D, E, F
