I don't believe that is necessarily the deontological response. Remember that morality is mostly a tool for exclusion; more than one moral choice often remains. A deontological person can still practice triage. Without more information (such as published policies, prior agreements, patient consent, etc.) it is hard to say if the question is even really a moral dilemma. If you are standing on the street and two people get hit by a bus, deciding which one to help is not a question of morality. By helping either, or both, you are acting morally, and perhaps even supererogatorily. Deciding whether or not you should go kick them while they're down, though, is a moral question. It would be moral (though not particularly praiseworthy) to refrain from doing so, and it would be clearly immoral to kick them. Interestingly, Catholics actually believe in the idea of a moral safe harbor. That is, if you've given serious and reasonable consideration to a moral question, and act in accordance with your earnest conclusion, then you will be held blameless regardless of the ultimate righteousness of the action.
