A nurse and a community health team are trying to define key members who should help lead the implementation of a community program. Which of the following individuals would be considered a community influencer?

Choice A Reason:
Assessing the client's wound is a task that requires clinical judgment and expertise, which falls under the scope of practice of a registered nurse (RN) or licensed practical nurse (LPN). Assistive personnel (AP) are not trained or authorized to perform assessments, as these require a higher level of clinical knowledge and decision-making.

Choice B Reason:
Notifying the case manager of the client's wishes for community resources involves communication and coordination of care, which are responsibilities typically handled by an RN or LPN. This task requires understanding the client's overall care plan and the ability to communicate effectively with other healthcare professionals.

Choice C Reason:
Reviewing the client's medications is a task that involves understanding the medications, their purposes, potential side effects, and interactions. This requires clinical knowledge and judgment, which are beyond the scope of practice for AP. Medication review is typically performed by an RN or LPN.

Choice D Reason:
Assisting the client with bathing and oral care is a task that falls within the scope of practice for AP. These activities are part of the basic care tasks that AP are trained to perform. They involve helping the client with daily living activities, which do not require clinical judgment or decision-making.

Choice A Reason:
Increased exposure increases the risk of developing the disease. This statement describes a dose-response relationship, which is another important criterion for establishing causation. It indicates that as the level of exposure to a potential cause increases, the risk of developing the disease also increases. However, this does not specifically address the temporal sequence required to establish causation.

Choice B Reason:
The exposure must come before the disease develops. This is the correct definition of a temporal relationship in epidemiological studies. For causation to be established, it is essential that the exposure to the potential cause occurs before the onset of the disease. This temporal sequence is crucial because it helps to rule out reverse causation, where the disease might influence the exposure rather than the other way around.

Choice C Reason:
When the exposure is decreased or eliminated, the risk of disease declines or is eliminated. This statement describes the concept of reversibility, which is another criterion for causation. It suggests that reducing or removing the exposure should lead to a decrease in the incidence of the disease. While important, it does not specifically define the temporal relationship.

Choice D Reason:
A relationship is biologically plausible, and it makes sense. This statement refers to biological plausibility, which means that the observed association between exposure and disease is consistent with existing biological or medical knowledge. While biological plausibility supports causation, it does not define the temporal sequence necessary to establish a causal relationship.
