Which statement from a student nurse indicates misunderstanding of the disaster triage tag system?

The statement regarding the use of a yellow tag for clients with shock reflects a misunderstanding of the disaster triage tag system. In this system, colors are assigned based on the severity of a patient's condition and the urgency of their medical needs. A yellow tag typically indicates a patient who requires care but has a delayed treatment need, often referred to as "urgent."

In contrast, clients experiencing shock are usually in a critical state requiring immediate medical attention; therefore, they should be categorized with a red tag, which is reserved for patients with life-threatening conditions who need urgent care. Understanding the proper application of the triage tag colors is essential for effective disaster response and prioritization of care during mass casualty incidents.

In this context, the other statements accurately reflect the triage tag categories: green tags do signify those who are walking wounded and can wait for treatment, red tags correctly refer to patients needing immediate care, and black tags are indeed used to denote deceased individuals.
