Probably don’t need all caps, plus saying to follow UW flow chart is not useful if you don’t use UW. Better to just remind that below T4 can involve abdomen.
You can follow any resource you want but considering this question is based on a uworld question so it would make sense to use the algorithm of the same source which no one can say it’s wrong
as per my comments on your other suggestion ‘I would also disagree with your sentence about what flow to follow - emphasis on ‘both compartments’ - a pericardial injury is more concerning in the acute sense than a spleen or liver injury.’
