The first yellow was due to the fractures, and the elevated pulse/decreased BP.
The second I considered yellow. My reasoning (with out looking at any protocols) is that with being pregnant, and the elevated vitals, she will need to go in and get checked out, but not get mixed in with the walking wounded when they make their mass exodus from the scene.
The third is obviously red. In a low manpower/high patient situation, though, she would probably be black.
