Informed consent in health care requires?

• A. Adequate information, voluntary decision, and capacity to decide
• B. A signature only
• C. A witness only
• D. A financial agreement

Answer: (A)

Informed consent hinges on three elements: adequate information, voluntary decision, and capacity to decide. Adequate information means the patient understands what will be done, the risks and benefits, possible alternatives, and what could happen if they decline treatment. Voluntariness means the choice is made freely, without coercion or pressure from clinicians, family, or others. Capacity means the patient has the ability to understand the information, appreciate the consequences, and communicate a clear choice. If any element is missing, the consent may not be valid, and steps should be taken to provide more information, assess understanding, or involve appropriate support. A signature alone does not guarantee understanding or voluntariness; a witness alone does not ensure comprehensive information or voluntary choice; and a financial agreement has no bearing on the patient’s ability to consent.
