Which component requires that the participant have adequate knowledge of the treatment, procedures, risks, and benefits?

• A. Capacity
• B. Voluntariness
• C. Confidentiality
• D. Information

Answer: (D)

Providing adequate information about the treatment, procedures, risks, and benefits is what makes consent informed. This information component ensures the participant has the knowledge needed to understand what they are agreeing to and to make a truly voluntary decision. Capacity refers to the person’s ability to understand and reason about the information and to communicate a choice, so without sufficient capacity, even well-presented information can’t lead to valid consent. Voluntariness is about freedom from coercion or undue influence, not the amount of knowledge. Confidentiality is about protecting privacy of information, not about the content or sufficiency of the information itself. In practice, you must present clear, complete information and verify understanding so informed consent is meaningful.
