Define DNR and other code status terms commonly used in hospitals.

• A. DNR means Do Not Resuscitate; DNI means Do Not Intubate; "Full code" means resuscitation attempted.
• B. DNR means Do Not Retry; DNI means Do Not Initiate; "Full code" means resuscitation not attempted.
• C. DNR means Do Not Resuscitate; DNI means Do Not Involve; "Full code" means resuscitation advised only if necessary.
• D. DNR means Do Not Resuscitate; DNI means Do Not Inhale; "Full code" means resuscitation attempted.

Answer: (A)

Understanding code status terms used in hospitals. DNR means Do Not Resuscitate; in the event of cardiac or respiratory arrest, CPR and related aggressive resuscitation are not attempted. DNI stands for Do Not Intubate; the patient declines placement of a breathing tube for mechanical ventilation, but other resuscitation efforts may still be pursued depending on the orders. "Full code" means resuscitation is attempted with all available measures, including CPR, defibrillation, airway management, ventilation, and medications.

The other options use terms that aren’t standard for these concepts: Do Not Retry isn’t how DNR is defined, Do Not Initiate isn’t how DNI is defined, and resuscitation not attempted contradicts the meaning of a full code.
