Question

what is the physicians ethical obligation regarding informed consent?
to ensure the patient and physician agree on a course of treatment
to allow the physician to make all medical decisions for the patient
to help the patient make choices from among the therapeutic alternative
to present the medical information in a manner that affects the decision - making process

Explanation:

Informed consent requires a physician to provide patients with all relevant medical information about therapeutic alternatives so they can make an educated choice. It's not about agreement on treatment (which may not always be reached), nor about the physician making all decisions, and presenting information should not be done in a way to unduly affect decision - making but to inform it.

Answer:

To help the patient make choices from among the therapeutic alternative
