Which of the following is NOT one of the three elements required for valid informed consent?

• A. Voluntary agreement
• B. Disclosure of information
• C. Patient capacity/comprehension
• D. Physician expertise

Answer: (D)

Valid informed consent hinges on three components: clear disclosure of information, patient capacity to understand, and voluntary agreement without coercion. The statement about the physician’s expertise is not one of these components. A clinician must be competent to perform the procedure and provide accurate information, but the consent itself rests on the patient’s understanding, decision-making ability, and free agreement. If information is missing or unclear, if the patient lacks capacity, or if there’s coercion, the consent isn’t valid—regardless of the clinician’s credentials. So, physician expertise is not one of the three elements of valid informed consent.
