Which statement about consent integrity is true?

• A. Consent is invalid if the patient does not understand what they are consenting to
• B. Consent is valid even if the patient is coerced
• C. Consent never needs to be revisited
• D. Written consent is never necessary

Answer: (B)

Consent integrity hinges on voluntary, informed decision making by someone who has the capacity to decide. When a patient does not understand what they are consenting to, they cannot truly appreciate the risks, benefits, and alternatives, so the agreement isn’t valid. Understanding is essential for true informed consent.

Coercion undermines voluntariness, so consent obtained under pressure isn’t valid either, even if the person signs it. Consent isn’t a one-and-done thing: if circumstances change or new information becomes available, consent should be revisited. Written documentation isn't universally required; some situations use verbal consent, while others demand written consent depending on risk and context.
