Which of the following is an example of implied consent?

Implied consent occurs in situations where a person's actions or circumstances indicate that they agree to receive medical treatment, even if they are unable to communicate that consent explicitly. In the case of an unconscious person, it is assumed that if they were able to communicate, they would want to receive emergency medical care. This principle is rooted in the ethical obligation to provide care to individuals who are unable to make decisions for themselves, particularly in emergencies where delay in treatment could lead to serious harm or deterioration of health.

Other scenarios such as a person dialing 911 or a guardian signing a consent form involve clear communication or specific permission being granted, which falls under informed consent rather than implied consent. Similarly, a guardian providing care for a minor implies responsibility and consent, but it does not align with the concept of implied consent that pertains to those unable to consent verbally or through actions.
