What describes implied consent?

• A. Consent indicated by a patient’s actions for example sitting in the chair
• B. Written consent required in all cases
• C. Verbal consent only
• D. Consent given by a guardian

Answer: (A)

Implied consent is when agreement to treatment is inferred from what the patient does rather than what they say in words. In practice, if a patient presents for care and cooperates with routine procedures—such as sitting in the chair and allowing the clinician to begin examination or cleaning—that behavior signals they are agreeing to proceed with the standard care. This form of consent works for routine, low-risk actions where asking for explicit, written permission for every step would be impractical.

It's important to contrast this with explicit consent, which is expressed in clear terms for more invasive or higher-risk procedures and is usually documented in writing or clear verbal agreement. Verbal consent can cover many situations, but it isn’t the same as implied consent, which is inferred from actions rather than a spoken agreement. Guardian consent is not implied consent from the patient; it applies when the patient cannot consent themselves, and a guardian or parent provides authorization.

So, the best description is that implied consent is consent inferred from the patient’s actions, such as sitting in the chair and allowing routine treatment to begin.
