Step-by-step explanation:
The legal procedure mentioned in the question that ensures the patient knows the benefits and costs of treatment before treatment occurs is called informed consent. Informed consent is an essential aspect of medical practice and research, where the patient or research participant is provided with comprehensive information about the proposed treatment or study, including the potential risks, benefits, and alternatives.
For example, when a patient is about to undergo surgery, the surgeon, nurse, and anesthesia professional review aloud the key concerns for the recovery and care of the patient. This process helps to ensure that the patient fully understands the procedure, its potential outcomes, and the associated costs.
Informed consent is a critical ethical requirement in the medical field, as it empowers patients to make informed decisions about their healthcare and protects their autonomy and rights.
