What are valid forms of DNR according to the policies?

The correct choice refers to specific legal documents that have been established to communicate a patient's wishes regarding resuscitation and medical interventions in critical situations. A Do Not Resuscitate (DNR) form is a legally recognized document that indicates a patient’s choice to forego resuscitation efforts in the event of cardiac arrest or respiratory failure. This form must be completed and signed by a physician as part of a comprehensive advance care planning process.

In addition to the DNR form itself, physician orders for life-sustaining treatment (POLST) are also important. These orders provide clear, actionable medical guidelines for healthcare providers regarding treatments the patient wishes to receive or avoid, reinforcing the patient’s previously stated wishes in a medical emergency.

Both the DNR form and POLST reflect a formal, documented consensus about the patient's desires which carry legal authority in emergency medical situations, ensuring that healthcare providers comply with the patient's wishes.

Contrastingly, the other options suggest various forms of communication about DNR status that lack the same legal weight or clarity. A verbal DNR from the patient may not be reliable in an emergency due to potential confusion or lack of documentation. Similarly, while advance health care directives are important, they may not specifically encompass immediate resuscitation decisions
