Question

multiple choice question
which of the following statements is true in regard to conducting ethical research?

an institutional review board must approve a study prior to its implementation from an ethical stand - point.

experienced experimenters do not need to have their studies approved by a research ethics commit - tee prior to implementation.

as long as all the participants who might be involved in the research study sign a waiver, then the study does not need any other approval.

only studies involving medications/medical research need approval by an institutional review board.

Explanation:

Ethical research requirements mandate that all human subjects research must receive prior approval from an Institutional Review Board (IRB) or research ethics committee, regardless of the researcher's experience, participant waivers, or the study's focus (not just medical research). The other options are incorrect: experienced experimenters still need approval, participant waivers do not replace formal ethical review, and non-medical human subjects research also requires IRB approval.

Answer:

An institutional review board must approve a study prior to its implementation from an ethical standpoint.
