Which statement lists the five elements that constitute informed consent?

• A. Information disclosure, patient consent, confidentiality, and parental approval.
• B. Voluntariness, competence, disclosure only; no written authorization required.
• C. Disclosure of information, comprehension by the patient, voluntariness, competence to decide, and explicit authorization to proceed with treatment.
• D. Brief explanation of risks, client signature, and clinician determination.

Answer: (C)

Informed consent hinges on ensuring the patient can make a voluntary, well-informed decision about care. The statement that lists five elements—disclosure of information, comprehension by the patient, voluntariness, competence to decide, and explicit authorization to proceed with treatment—embodies this process. Disclosure means providing clear details about the procedure, alternatives, risks, benefits, and likely outcomes. Comprehension means the patient truly understands what has been explained. Voluntariness ensures the choice is made without coercion or pressure. Competence to decide means the patient has the mental ability to weigh the information and make a decision. Explicit authorization means the patient gives a clear, deliberate consent to proceed, typically documented in writing or through a clearly stated verbal agreement.

The other options omit or misstate essential parts: one lacks comprehension or explicit consent and includes unrelated elements like confidentiality or parental approval; another narrows to voluntariness and competence without full disclosure or understanding and wrongly suggests written authorization isn’t required; and the last focuses only on a brief risk explanation, a signature, and clinician determination, missing the patient’s understanding and voluntary decision.
