Which of the following would be classified as expressed consent?

Expressed consent refers to a clear and direct agreement from a patient to receive medical treatment. This can be verbal or written, and it indicates that the patient understands the proposed treatment and agrees to it.

In this case, the selection of a verbal agreement aligns with the definition of expressed consent because it involves the patient actively communicating their approval for treatment. This is a crucial aspect of informed consent in medical practice, as it ensures that the patient is participating in their own care decisions.

The other options do not meet the criteria for expressed consent. A nod of agreement might imply consent but is not sufficiently explicit or clear on its own, lacking a verbal or formal acknowledgement. The provision of care to an unconscious patient, while sometimes permissible under the concept of implied consent, does not represent expressed consent since there is no communicative indication of agreement from the patient. Lastly, being in a condition that rules out the ability to consent means that consent cannot be obtained, making it impossible for the patient to express their wishes regarding treatment. Thus, the clear and active communication implied by a verbal agreement is what classifies it as expressed consent.
