Which statement lists the three key elements of valid consent?

• A. Informed, written and voluntary
• B. Informed, voluntary, and given by a competent individual
• C. Voluntary, specific, informed
• D. Competent, witnessed, documented

Answer: (B)

Valid consent hinges on three things: the person has enough information to understand what will happen, they decide freely without pressure, and the person giving consent has the capacity to make that decision at the time. When someone is informed, they know what is proposed, why it’s needed, the risks and benefits, and any reasonable alternatives. Voluntary means they choose without coercion or real-world pressure and feel free to accept or decline. Given by a competent individual means the patient has the mental capacity to understand the information and make the decision themselves (if they lack capacity, a legally appropriate representative or process must be used). While written, witnessed, or documented consent can help evidence that consent was obtained, they are not the defining elements of validity themselves.
