Which of the following types of consent is the patient demonstrating when they extend their arm to a medical assistant for venipuncture

Expressed consent involves a clear and explicit agreement given verbally or in writing by the patient. In this case, the patient did not verbally communicate their consent; instead, their action of extending the arm serves as a non-verbal cue, which is characteristic of implied consent rather than expressed consent.

Informed consent requires that the patient has been given comprehensive information about the procedure, including risks, benefits, and alternatives, allowing them to make an educated decision. The mere act of extending an arm does not indicate that the patient has received or acknowledged this critical information.

Statutory consent refers to consent that is mandated by law for specific situations, often involving minors or individuals unable to give consent. In this case, the patient is actively participating in the consent process through a physical gesture, making statutory consent irrelevant to this scenario.
