It would make more sense to just use IRT for grading the responses than trying to add more complexity to the answers themselves.
I seem to remember some medical related multiple choice tests in the UK use a mechanism of +1 for correct , 0 for unanswered , -1 for incorrect.
A system like that seems especially appropriate for a practice where the foundational principle is "do no harm."
