What is the difference between primary and secondary surveys in rescue medicine?

• A. Primary assesses life threats and stabilizes; secondary conducts a head-to-toe assessment after stabilization
• B. Primary is a medical imaging test
• C. Primary is performed after transport
• D. Primary and secondary are identical in scope

Answer: (A)

In rescue medicine, the order and purpose of assessments matter: first identify and stabilize life threats, then perform a thorough check for other injuries. The primary survey is a rapid, focused pass that looks for and immediately treats the biggest dangers to life—airway with cervical spine protection, breathing, circulation, disability (neurologic status), and exposure. The goal is to stabilize the patient as quickly as possible so they can be moved or receive definitive care.

Once those immediate threats are managed, the secondary survey begins. This is a detailed head-to-toe examination to uncover injuries that aren’t life-threatening right away, along with gathering history, noting mechanism of injury, rechecking vitals, and continuing reassessment. This sequencing—stabilize first, then a comprehensive assessment—is what makes the described distinction correct.

The other ideas don’t fit: the primary survey is not an imaging test, it occurs before transport, and the two surveys are not identical in scope—the primary focuses on life threats, while the secondary expands to a full injury assessment after stabilization.
