Informed consent is based on three legal principles: the patient must: one. be competent to give consent, two. give consent freely, three. confer with and agree with family members four. have an adequate understanding of the proposed treatment including potential risks.

Applying ethical principles to medicine-Autonomy influenced by cultural and religious beliefs
-In some cultures, family members have a primary or at least equal, voice about patient's care. Thus, an individual's autonomy is offset by respect for the values of others with whom one has a significant relationship.Ethicsconcerned with the investigation of what is good and what is bad, especially as these concepts relate to moral duties and obligations.Moral principles-The investigation of ethics results in these principles that guide behavior. 
-Essentially what is right and what is wrong.Beneficenceanother fundamental principle in medical care
-involves doing good or conferring benefits that enhance personal or social well-being.Non-maleficenceCounterpart to beneficence

--> physicians are not to abandon a patient even when he/she takes actions that he/she believes are ill advisedAutonomyRefers to an individual's rights to be self-governing. Our personal autonomy is limited by the rights of others to exercise their autonomy, and it may also be limited by society.

-Its antecedents go back hundreds of years to English Common Law
-By the late 1970's, most physicians stated, in a survey, that they would tell their patients the truth in regards to their diagnosis. However, this was found to be somewhat false in certain complicated or sensitive ethical issues.Preferences regarding informed consentLack of Communication may cause DNR (Do Not Resuscitate) orders to be ignored even when they exist.
