In medical research involving human subjects, which are key ethical and legal considerations?

• A. Protecting Risk/Benefit Balance and Obtaining Independent IRB Review
• B. Ignoring Informed Consent to Speed Up Research
• C. Excluding Risk Assessment and Relying on Data Anonymity
• D. Avoiding Any Disclosure of Conflicts of Interest

Answer: (A)

The central idea is protecting participants by balancing risks and benefits and ensuring independent oversight of the study. Evaluating whether potential benefits justify the risks, and having an independent IRB review the protocol, consent process, and safety measures, together uphold ethical and legal standards for research with human subjects. This framework embodies respect for persons, beneficence, and justice, plus regulatory accountability.

The other options miss essential protections: ignoring informed consent violates autonomy and legal requirements; excluding risk assessment and relying only on anonymity leaves participants exposed to harm without proper safeguards; and concealing conflicts of interest undermines trust and can bias the study.
