A community health nurse is preparing an in-service for staff to define the conditions of causation in epidemiology studies. Which of the following descriptions should the nurse use to define a cessation of exposure to establish causation?
"When the exposure is decreased or eliminated, the risk of disease declines or is eliminated."
"The exposure must come before the disease develops.
"A relationship is biologically possible, and it makes sense."
"Increased exposure increases the risk of developing the disease."
The Correct Answer is A
Choice A: "When the Exposure is Decreased or Eliminated, the Risk of Disease Declines or is Eliminated."
This statement accurately describes the concept of cessation of exposure in establishing causation. According to the Bradford Hill criteria, if a factor is truly causal, reducing or eliminating exposure to that factor should lead to a decrease in the incidence of the disease. This principle helps to confirm the causal relationship between the exposure and the disease.
Choice B: "The Exposure Must Come Before the Disease Develops."
This statement refers to the temporal relationship criterion in the Bradford Hill criteria, which states that for an exposure to be considered causal, it must precede the onset of the disease. While this is an important aspect of establishing causation, it does not specifically address the concept of cessation of exposure.
Choice C: "A Relationship is Biologically Possible, and it Makes Sense."
This statement pertains to the biological plausibility criterion, which suggests that the observed association between an exposure and a disease should be consistent with existing biological and medical knowledge. While biological plausibility is crucial for establishing causation, it does not directly relate to the cessation of exposure.
Choice D: "Increased Exposure Increases the Risk of Developing the Disease."
This statement describes the dose-response relationship, another criterion in the Bradford Hill framework. It indicates that a greater level of exposure to a risk factor should correspond to a higher risk of developing the disease. Although this is an important aspect of causation, it does not specifically address the cessation of exposure.

Correct Answer is C
Explanation
Choice A: "I Think That I Missed Two Math Tutoring Classes Last Week, But I Can Still Catch Up."
This statement indicates that the client is aware of their academic responsibilities and is optimistic about catching up. Missing a couple of classes is not uncommon, and the client's positive attitude towards catching up is a good sign. This statement does not indicate an immediate need for intervention regarding their mental health.
Choice B: "I Have Not Used Drugs in 6 Weeks."
This statement is positive and indicates progress in the client's efforts to stay away from substance use. It shows that the client is making strides towards healthier behaviors, which is a crucial aspect of their overall well-being. This statement does not require immediate intervention but should be acknowledged and supported.
Choice C: "I Don't Have Anyone I Can Talk to About My Problems."
This statement is concerning and indicates a lack of social support, which is critical for someone with a history of depression and suicidal ideation. Feeling isolated and having no one to talk to can exacerbate feelings of depression and increase the risk of suicidal thoughts. This statement requires immediate intervention to ensure the client receives the necessary support and resources to address their feelings of isolation.
Choice D: "I Have Been Participating in My Local YMCA After-School Dance Program Again."
This statement is positive and indicates that the client is engaging in social and physical activities, which can be beneficial for their mental health. Participation in such programs can provide a sense of community, improve mood, and reduce feelings of isolation. This statement does not require immediate intervention but should be encouraged and supported.
Correct Answer is ["A","B","D","E"]
Explanation
Choice A Reason:
a) Assess the community: This is the first step in addressing community health needs. It involves gathering data about the community's health status, resources, and needs. This can be done through surveys, interviews, focus groups, and public forums. The assessment helps to identify the health problems and needs of the community, which is essential for planning effective interventions.
Choice B Reason:
b) Analyze the findings and identify the needs: After collecting data, the next step is to analyze it to identify the community's health needs. This involves looking at the data to find patterns and trends that indicate health problems. By identifying these needs, the nurse can prioritize which issues to address first. This step is crucial for developing a targeted and effective health plan.
Choice C Reason:
c) Decide on educational theories to use: This step is not directly related to the initial assessment and planning process. Deciding on educational theories is more relevant when planning specific health education interventions. While important, it is not a primary step in assessing and addressing community health needs.
Choice D Reason:
d) Use measurable indicators to evaluate the plan: Using measurable indicators is essential for evaluating the effectiveness of the health plan. These indicators help to track progress and determine whether the interventions are achieving the desired outcomes. This step ensures that the health plan is effective and allows for adjustments to be made if necessary.
Choice E Reason:
e) Collaborate with the residents of the community on what interventions will work for that community and prioritize them: Collaboration with the community is vital for the success of any health intervention. By involving community members in the planning process, the nurse can ensure that the interventions are culturally appropriate and accepted by the community. This collaboration also helps to prioritize the interventions based on the community's needs and preferences.
