After explaining all treatment options and the patient verbally agrees to proceed, what type of consent is this?

Correct answer: A. Informed consent

• A. Correct. Disclosure of options/risks/benefits followed by the patient's voluntary agreement constitutes informed consent (here documented as an expressed/verbal agreement).
• B. Implied consent is inferred from actions (e.g., sitting in the chair, opening the mouth) without explicit discussion.
• C. Statutory consent applies to legally mandated situations.
• D. Proxy consent is given by a surrogate when the patient cannot consent.

Note: Because the patient explicitly stated agreement, this can also be called 'expressed consent'; it is a form of informed consent.
