Which client injury would receive a black tag by the triage nurse during a mass casualty incident?

In a mass casualty incident, the triage process is critical for determining the priority of treatment based on the severity of injuries and the likelihood of survival. The black tag is used for victims who are considered "deceased" or whose injuries are so severe that they are not expected to survive, even with medical intervention.

A client with full-thickness body burns covering 80% of total body surface area (TBSA) would indeed receive a black tag because such an extensive burn is associated with significant physiological damage and a high mortality rate. Patients with this level of injury typically face insurmountable challenges, including shock, respiratory failure, and overwhelming infection, which make it unlikely for them to survive even with intensive treatment. Therefore, in a triage scenario aimed at maximizing the overall survival of victims, this patient would be prioritized as one requiring no immediate lifesaving resources.

The other options presented reflect injuries that may require urgent medical attention but are not considered immediately fatal, allowing for the potential for recovery with appropriate medical care.
