Rationale: A triage method commonly used in the emergency department consists of three cate-gories: emergent, urgent, and nonurgent. The emergent category implies that a condition exists that poses an immediate threat to life or limb; an example of a client who fits into this category is the client experiencing crushing substernal pain who is short of breath. The urgent category in-dicates that the client should be treated quickly but that an immediate threat to life does not exist at the moment. The client with a displaced fracture and the client with a temperature of 101 F would fit into this category. The nonurgent category indicates that the client can generally toler-ate waiting several hours for health care services without a significant risk of clinical deteriora-tion. The client with a simple laceration and soft tissue injury would fit into this category.
