While a nurse manager is conducting a disaster-preparedness drill, they observe nurses applying triage tags to clerical staff who are posing as injured clients. The manager should expect the nurses to apply which of the following tags to a client who has an ankle sprain?

Rationale: A. This option is incorrect because a red tag is reserved for clients with life-threatening injuries who need immediate medical intervention to survive. Examples include severe hemorrhage, airway compromise, or major trauma affecting vital organs. An ankle sprain does not pose a threat to life and does not require urgent treatment, so assigning a red tag would misallocate critical resources. B. This option is incorrect because a yellow tag is used for clients with serious injuries that require care but are not immediately life-threatening. These clients may have fractures or moderate internal injuries that can tolerate a short delay in treatment. While more serious than a minor sprain, an ankle sprain does not meet the criteria for a yellow tag. C. This option is correct because a green tag is applied to clients who have minor, non-life-threatening injuries. These individuals, often called "walking wounded," include those with minor sprains, abrasions, small lacerations, or mild contusions. Green-tagged clients can wait for treatment while healthcare resources are directed toward patients with more critical needs, which is a key principle of triage during disasters. D. This option is incorrect because a black tag indicates clients who are deceased or have injuries so severe that survival is unlikely, even with immediate intervention. An ankle sprain is a minor injury with no threat to life, making the black tag inappropriate.
