Which type of consent involves a patient taking an action that indicates permission for care?

The correct answer is implied consent. Implied consent occurs when a patient's actions suggest that they agree to treatment or care even if they have not explicitly verbalized or documented their consent. For instance, if a patient rolls up their sleeve for a blood draw, their action indicates they are permitting the procedure, demonstrating implied consent.

Expressed consent refers to a situation where the patient explicitly agrees to a treatment or intervention, often in written form, and is not the correct choice in this context. Informed consent involves a thorough understanding of the procedure, risks, and benefits, requiring more than just a simple action; it necessitates that the patient has been adequately informed to give an informed decision. Informed refusal signifies a patient's decision not to undergo a proposed treatment after being informed about it, which does not apply to the question of indicating permission.
