Answer:
by showing that the patient has signed a consent form
Step-by-step explanation:
The Consent Form is a basic and fundamental document of medical protocol and ethics. It is the source of clarification that will allow the patient to make his decision as to whether to accept and authorize a particular treatment or medical procedure in a fair and unimpeded way. In addition, this document allows the patient to give consent to the disclosure of their medical information, which is confidential information and can only be disclosed if the patient agrees and signs this document.
