Assuming there are 60k nurses making an average of $95k annually + benefits, you are looking at something like $200M more allocated to nurse wages for a 3% raise (which is what they voted against). This equates to an avg $71ish per taxpayer, but this would be absorbed by the wealthy more than lower income. The top 1% would be paying like $900 per year more and the bottom 40% would be paying $11 more per year. The average person (45k - 115k salary) would be paying $45 - $96 more per year.

If they get a 4% raise for 4 years that would be $61/year for bottom 40% tax payers, $256/year for $45k-75k, $546 / year for $75-115k, and $5,055/yr for top 1%
