Which is NOT an essential element of valid informed consent in end-of-life decisions?

• A. Competence
• B. Voluntary choice
• C. Disclosure of information
• D. Confidentiality

Answer: (D)

What makes informed consent valid is that the patient has the capacity to understand, makes a voluntary choice, and has received adequate information about options, risks, benefits, and alternatives. Competence ensures the person can grasp what’s happening and appreciate the consequences of their decision. Voluntary choice means no coercion or undue pressure. Disclosure of information provides the data needed to make an informed decision.

Confidentiality, while a fundamental ethical obligation in care, is not part of what determines the validity of the consent itself. It protects privacy and restricts who can know or share what the patient has discussed, but the essential elements that render consent valid are capacity, voluntary decision, and sufficiency of information.
