Observers conducting research via the ethnonursing method should interact with the interviewee as:

A) Active observers.
B) Theory authorities.
C) Expert interviewers.
D) Data collection experts.

Ethnonursing is a qualitative research method that involves active observation and interaction with the participants or interviewees. The observer should be actively engaged in the process, carefully observing the participant's behavior, reactions, and non-verbal cues, and asking follow-up questions to gain deeper insights into the participant's experiences and perspectives. Ethnonursing emphasizes the importance of cultural sensitivity, reflexivity, and building trust with the participants to ensure that the research results are respectful, accurate, and meaningful. Therefore, the observer should be an active observer rather than a theory authority, expert interviewer, or data collection expert.
