Final answer:
A Do Not Resuscitate (DNR) order specifically outlines the exclusion of cardiopulmonary resuscitation (CPR) from medical interventions should the patient's breathing or heart stop.
Step-by-step explanation:
According to the Do Not Resuscitate (DNR) standard, the measure excluded from being performed is b. Cardiopulmonary resuscitation (CPR). A DNR order indicates that medical personnel, such as doctors and nurses, should not initiate CPR if the patient's breathing stops or if the patient's heart stops beating. The DNR is commonly included within an advanced directive or living will, and its implementation is a form of voluntary passive euthanasia that is legal in the United States. It is important to understand that a DNR order specifically addresses the non-initiation of CPR and does not extend to other forms of medical intervention, which may include airway management, oxygen administration, or wound dressing unless specifically stated in an individual's advance directive.
