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?

Choice A: Implementing the Teach Back Method When Prescribing Medication
The Teach Back Method is an effective communication strategy where healthcare providers ask clients to repeat back the information given to ensure understanding. While this method can improve medication adherence and health literacy, it does not directly address the broader systemic issues related to poverty. It is a useful tool but not the most impactful intervention for breaking the cycle of poverty.

Choice B: Replacing Medicare Programs with Medigap Policies
Medigap policies are supplemental insurance plans that cover costs not included in traditional Medicare. However, replacing Medicare programs with Medigap policies would not necessarily improve outcomes for clients impacted by poverty. Medigap policies can be expensive and may not be affordable for low-income individuals. This intervention does not address the root causes of poverty or improve access to essential health services.

Choice C: Eliminating the Use of Client Portals or Virtual Visits
Eliminating client portals or virtual visits would likely have a negative impact on client outcomes, especially for those in poverty who may have limited access to transportation. Virtual visits and client portals provide convenient access to healthcare services, allowing clients to communicate with providers, access medical records, and receive care without the need for in-person visits. Removing these options would reduce access to care for many individuals.

Choice D: Opening a Community Health Center in an Underserved Area
This is the correct choice. Opening a community health center in an underserved area directly addresses the lack of access to healthcare services, which is a significant barrier for individuals living in poverty. Community health centers provide comprehensive primary care, preventive services, and support for managing chronic conditions. They often offer sliding scale fees based on income, making healthcare more affordable and accessible for low-income populations. By improving access to healthcare, community health centers can help break the cycle of poverty and improve overall health outcomes.

Choice A Reason:
This statement is incorrect because it describes a true negative, not a false negative. A true negative occurs when the test correctly identifies that a person does not have the disease. In a two-by-two table, this is represented in the cell where both the actual status and the test result indicate no disease.

Choice B Reason:
This statement is incorrect because it describes a true positive, not a false negative. A true positive occurs when the test correctly identifies that a person has the disease. In a two-by-two table, this is represented in the cell where both the actual status and the test result indicate the presence of the disease.

Choice C Reason:
This statement is correct because it accurately describes a false negative. A false negative occurs when the test incorrectly indicates that a person does not have the disease when, in fact, they do. In a two-by-two table, this is represented in the cell where the actual status indicates the presence of the disease, but the test result indicates no disease.

Choice D Reason:
This statement is incorrect because it describes a false positive, not a false negative. A false positive occurs when the test incorrectly indicates that a person has the disease when, in fact, they do not. In a two-by-two table, this is represented in the cell where the actual status indicates no disease, but the test result indicates the presence of the disease.
