When obtaining informed consent, what must medical assistants ensure patients understand?

Informed consent is a fundamental principle in healthcare, emphasizing the patient's right to be fully informed about their treatment options. Selecting the option regarding the patient’s right to understand the procedure, associated risks, and alternatives is critical because it encompasses the key aspects of informed consent. Medical assistants must ensure that patients are not only aware of the specifics of the procedure but also understand any potential risks involved and other treatment options available to them. This knowledge allows patients to make educated decisions regarding their healthcare based on a complete understanding of their situation.

Focusing solely on whether the procedure is mandatory, the risks of avoiding treatment, or the cost of the procedure would not meet the criteria for informed consent. Patients need comprehensive knowledge about their care to give valid consent, which reinforces the importance of option C in the context of ethical medical practices.
