The action that is typically part of the secondary assessment of a conscious patient is formulating a differential diagnosis. This step follows a detailed history and a head-to-toe examination to identify non-life-threatening or less obvious injuries and conditions that may require targeted management.

Key points:

• Secondary assessment aims to uncover injuries not evident during the primary survey and to refine diagnoses after initial stabilization.

• It involves a thorough history, a complete physical examination, and the development of a differential diagnosis based on findings.

• Other actions listed, such as attaching monitors or giving IV/IO fluids, are typically associated with the primary assessment or immediate management rather than the secondary survey.
