Which type of consent involves the patient actively communicating their willingness to receive treatment?

The correct choice involves expressed consent, which is characterized by the patient actively communicating their willingness to receive treatment. This type of consent can be given verbally or in writing and indicates that the patient understands the nature of the treatment and agrees to proceed with it.

Expressed consent is particularly important in medical scenarios where clear communication is essential to ensure that the patient is fully aware of what they are consenting to, including any potential risks involved. It reflects a patient's autonomy in making informed decisions about their healthcare.

In contrast, implied consent refers to situations where consent is assumed based on the circumstances, such as in emergencies where a patient is unable to communicate. Informed consent involves providing comprehensive information about the procedure, including risks and benefits, but may not always require active communication from the patient. Emergency consent typically pertains to lifesaving treatments when immediate action is necessary, and obtaining expressed consent is not feasible.
