If nurses at a Jamaican clinic only inform subjects about research opportunities, are they engaged in the research?

The correct answer focuses on the roles and responsibilities outlined in research ethics, particularly regarding participation and consent in research activities. Nurses informing subjects about research opportunities does not constitute engagement in the research itself, as engagement typically involves direct interaction with the participants that falls under the purview of conducting the study.

To be considered engaged in research, individuals must be involved in activities that directly influence the study's design, conduct, or outcomes, such as obtaining informed consent or implementing study procedures. Simply providing information about research opportunities does not meet this threshold, as they are not making decisions nor directly soliciting participation.

Consent is a critical aspect of ethical research, and nurses informing participants merely lays the groundwork for potential participation without crossing into the realm of active research engagement. Thus, the absence of consent-taking or the implementation of research interventions indicates that they are not engaged in the research, validating this answer.
