Final answer:
In a community disaster, a nurse uses a triage system to prioritize patient care based on the severity of their injuries. The colors used in the triage system are red, yellow, green, and black.
Step-by-step explanation:
In a community disaster, the nurse uses a triage system to determine the priority of care for patients. The colors used in the triage system are:
- Red: This tag is used for patients with life-threatening injuries who require immediate medical attention.
- Yellow: This tag is used for patients who have serious injuries but are stable and can wait a little longer for medical treatment.
- Green: This tag is used for patients with minor injuries who do not require immediate medical attention.
- Black: This tag is used for patients who are deceased or whose injuries are so severe that they are not expected to survive.
By tagging patients with appropriate colors, the nurse can prioritize the care and allocate resources efficiently during a community disaster.
