Which type of consent involves explicit agreement from the patient?

• A. Express consent
• B. Implied consent
• C. Advance directive
• D. None of the above

Answer: (A)

Consent can be explicit or inferred. The type that involves explicit agreement from the patient is express consent, meaning the patient gives a clear, affirmative permission to a proposed medical intervention after being informed about what it involves. This can be written on a consent form or stated verbally, showing the patient’s active assent to proceed. Implied consent is inferred from the patient’s actions or the clinical situation (such as showing up for treatment or an emergency where immediate care is needed). An advance directive is a document that outlines future care preferences and isn’t the same as giving explicit consent for a specific procedure right now. Express consent best fits the idea of explicit agreement from the patient.
