What is the purpose of a secondary assessment?

• A. To identify life threats during the primary survey
• B. To determine the cause of illness
• C. To identify additional injuries or conditions not found during the primary survey
• D. To decide hospital destination

Answer: (C)

The main purpose of a secondary assessment is to uncover injuries or medical conditions that weren’t obvious during the initial, life-threat focused evaluation. After the primary survey confirms there are no immediate threats to breathing, circulation, or consciousness, you perform a thorough head-to-toe exam and gather a more complete patient history. This helps you spot injuries that may not be evident at first glance—things like hidden abdominal bleeding, a small fracture, or a nonobvious medical issue that could affect how you treat and transport the patient.

Gathering information (like a detailed history using a SAMPLE framework) and reassessing vital signs during the secondary assessment also guides ongoing care and helps you plan what to monitor and what to do en route to the hospital. It’s not about identifying life threats—that’s done in the primary survey—nor about diagnosing the exact cause of illness; instead, it’s about filling in the gaps so nothing important is missed and care is appropriately tailored. The decision on transport destination may be influenced by the overall condition, but identifying additional injuries or conditions is the core purpose of the secondary assessment.
