Informed consent validity, which condition must be ensured?

• A. The patient must have the capacity to understand and give voluntary consent without coercion
• B. Consent is optional if the patient agrees verbally
• C. The consent must be obtained only for invasive procedures
• D. The patient’s family can provide consent if the patient is unable

Answer: (A)

Informed consent is valid only when the patient has the capacity to understand the procedure and to give voluntary consent without coercion. Capacity means the patient can comprehend what’s being proposed, including risks, benefits, and alternatives, and can reason about what to choose. Consent must also be voluntary, given free from pressure, manipulation, or threats from others. If a patient cannot make decisions, a legally authorized representative may consent on their behalf, rather than relying on family members who aren’t legally empowered. Verbal consent can be sufficient in many situations, but it still must come from someone who has both understanding and freedom from coercion.
