What should you do for a patient with leukemia who has a valid Do Not Resuscitate (DNR) order?

Providing oxygen and any other supportive care for a patient with leukemia who has a valid Do Not Resuscitate (DNR) order is appropriate because it aligns with the ethical and legal considerations involved in caring for patients with such orders. A DNR order specifically indicates that the patient does not wish to receive CPR or advanced cardiac life support measures in the event of cardiac or respiratory arrest. However, this does not preclude offering other forms of care to ensure patient comfort and quality of life.

In this scenario, supportive care can involve administering oxygen to alleviate any symptoms of hypoxia and ensuring the patient's comfort, which is consistent with respectful palliative care approaches, particularly for patients with terminal conditions like leukemia. This choice recognizes the patient's autonomy and respects their wishes while still providing empathetic and necessary care.

The other options fail to respect the DNR order. Attempting resuscitation contradicts the patient's explicit wishes. Clearing the scene without offering support would demonstrate a lack of compassion and could cause additional distress to the patient and their family. Asking the family if they are sure about the DNR order could be inappropriate and may lead to confusion and distress, as the order is already in place and should be respected by medical professionals.
