Which statement defines informed consent?

• A. The patient understands the treatment and agrees to proceed
• B. The patient is informed of the options but does not need to consent
• C. The patient understands the treatment, risks, and alternatives — and agrees voluntarily
• D. Consent is not required if the clinician believes it is best

Answer: (C)

Informed consent is about the patient having enough information to make a real choice, truly understanding what will happen, the potential risks, and the alternatives, and then agreeing to proceed of their own free will. In a dental context, this means discussing the nature of the proposed treatment, the possible risks or complications, and viable alternatives (including doing nothing), so the patient can weigh options and decide. The patient must have the capacity to decide, and the clinician should check understanding and answer questions before the decision is documented.

The statement that best defines informed consent says the patient understands the treatment, the risks, and the alternatives — and agrees voluntarily. This captures all essential elements: information, understanding, and voluntary agreement. The other options miss parts of this process—for example, focusing only on understanding and proceeding without explicit discussion of risks or alternatives, or implying consent isn’t needed, which isn’t ethical or legal.
