What should informed consent address regarding revocation of consent?

• A. Consent cannot be withdrawn.
• B. Limits on revocation of consent.
• C. Revocation only for financial reasons.
• D. Revocation is automatically granted.

Answer: (B)

The key idea is that informed consent is about patient control over decisions and should spell out what happens if they change their mind. It should specifically address limits on revocation, so the patient understands any practical or legal boundaries—such as whether revocation can undo ongoing treatment, or whether actions already taken or irreversible steps can’t be reversed. This clarity protects patient autonomy while setting realistic expectations for what revocation can mean in a real clinical or care context. Statements that claim consent cannot be withdrawn or that revocation is automatic misrepresent how consent functions in practice.
