Two school buses carrying 75 children each collide en route to an out-of-state field trip. The emergency department nurse knows that reverse triage will need to be instituted. What principles should the nurse follow when implementing reverse triage?

Select all that apply.
1. When there is a mass casualty event with more than 100 victims, reverse triage may be instituted.
2. Reverse triage works on the principle of the greatest good for the greatest number.
3. A very basic reverse triage system is to categorize or label victims needing the most support and emergency care as red, so they can be treated first.
4. Victims most likely to survive are color-coded black, and are treated first.
5. Reverse triage works on the principle of the greatest good for the most critically ill.

Answer to Question 1

Correct Answer: 1,2

When there is a mass casualty event with more than 100 patients, reverse triage may be instituted. Reverse triage works on the principle of the greatest good for the greatest number. Labeling victims needing the most support and emergency care as red so they can be treated first is a principle of basic triage. Victims who are color-coded black are not likely to survive. Basic triage works on the principle of the greatest good for the most critically ill.

Answer to Question 2

Correct Answer: 1

After a blast injury, damage to the ear can include tympanic membrane rupture or damage to the cochlea. As the patient is expressing difficulty hearing, the tympanic membrane should be assessed. An air embolism would impact the patient's respiratory status. There is no evidence to suggest the patient's oxygen saturation level is impaired. There is no evidence of confusion.
