I always tell my students to verbalize and use hands on approach as if they were teaching patient assessment.
Now which is better? I am checking the head, for injuries such as battles signs, PEARLA" or "I am checking for battle signs, which is bruising behind the ears on the mastoid process, which is an indicator for a basilar skull fracture", "Looking and examining the eyes, not only equal and reactive but the speed if reactivity, as well checking for potential foreign bodies, sclera for jaundice, conjunctiva color, gray which could be an indicator for hemorrhage and shock..."
I would suggest write everything one can potentially observe and find, and rehearse and re-rehearse over and over again. Where you actually know how and what to assess... remember after identifying and acknowledging "crucial areas, and appropriate treatment, rapid transportation".. you can hone into a detail assessment.. If one impresses the evaluator, they might overlook mistakes you had made... as well they see the same routine assessment over and over as well.. so seeing something new and sharp is impressive.
Good luck,
