The process used by the nurse to determine which patient is most ill and should be seen by a physician first is called triage. Triage is a process of sorting and prioritizing patients based on the severity of their medical conditions and the urgency of their need for treatment. The goal of triage is to ensure that the most critical patients are seen by a physician first and that patients with less urgent conditions receive appropriate and timely care.

Nurses who perform triage are often called triage nurses or emergency room nurses. They are specially trained to assess patients' conditions quickly and accurately. During the triage process, the nurse will gather information from the patient, such as their symptoms, medical history, and vital signs (such as blood pressure, heart rate, and respiratory rate). The nurse may also order diagnostic tests, such as blood tests or x-rays, to help determine the severity of the patient's condition.

Based on the information gathered, the nurse will assign the patient a triage level, which indicates the urgency of their need for medical attention. Triage levels are typically categorized using a color code, such as red (most urgent), yellow (urgent), green (less urgent), and white (non-urgent).

The patient with the highest triage level will be seen by a physician first, followed by the patient with the next highest triage level, and so on. This ensures that the most critically ill patients receive the care they need in a timely manner.
