Which scenario best illustrates ethical research conduct?

• A. Obtaining informed consent, minimizing risk, protecting participant confidentiality, and ensuring IRB oversight.
• B. Obtaining consent only.
• C. Minimizing risk without consent.
• D. No IRB oversight is required.

Answer: (A)

Ethical research conduct centers on respecting participants, minimizing harm, protecting privacy, and ensuring independent review. Informed consent is essential because it ensures participants understand what the study involves, the potential risks and benefits, and that participation is voluntary. Minimizing risk means designing the study to reduce physical, psychological, or social harm to participants. Protecting confidentiality safeguards the privacy of their data and who has access to it. IRB oversight provides an independent evaluation of the protocol, weighing risk versus benefit, ensuring proper consent materials, and monitoring ongoing safety. When a scenario includes all of these elements—clear, voluntary consent; a plan to minimize risk; strong confidentiality protections; and IRB review and oversight—it best demonstrates ethical conduct in research. Choices that rely on consent alone, or minimize risk without consent, or omit independent review, fail to protect autonomy, safety, or ethical accountability.
