Expressed consent involves a clear, direct agreement, typically given verbally or in writing, for a specific medical procedure. In this scenario, the patient has not verbally or explicitly stated their consent; instead, they have shown it through their actions. Therefore, expressed consent is not applicable here.

Verbal consent requires the patient to explicitly state their agreement to a procedure through spoken words. In this case, the patient has not provided a verbal acknowledgment but instead has communicated consent through physical action, making verbal consent an incorrect choice for this situation.

Informed consent necessitates that the patient is fully aware of the procedure's risks, benefits, and alternatives before agreeing to it. While the patient's action indicates consent, there is no evidence that they have been informed about the procedure, making this choice inappropriate in this context.
