Before informed consent may be obtained, what should the investigator provide?

• A. The investigator should provide ample time to inquire about details of the trial and to decide whether or not to participate; all questions should be answered to the satisfaction of the subject.
• B. The subject must decide to participate immediately.
• C. All questions about the trial should be answered only if the subject asks.
• D. The investigator should provide ample time to inquire about details of the trial and to decide whether or not to participate; all questions should be answered to the satisfaction of the subject.

Answer: (D)

Before informed consent is obtained, the investigator must ensure the potential participant has ample time to review the trial details and decide whether to participate, and that all questions are answered to the participant's satisfaction. This protects the person’s autonomy by allowing thorough understanding and a voluntary decision, not a hurried or pressured choice. The discussion should cover what the study involves, potential risks and benefits, alternatives, confidentiality, costs or compensation, and who to contact with questions, with the investigator confirming understanding and offering further clarification as needed.
