Assume you currently employ 4 8 nurses per shift who work 1 2 - hour shifts and get 9 0 minutes for breaks during each shift. Nurses are available for rounding ( i . e . , caring for patients ) for 7 5 % of their time. Rounding demand is 1 , 5 1 2 patient visits per shift. How many minutes should a nurse spend with each patient during rounds to keep up with demand? Assume subsequent rounds with the same patient during a shift are counted as a separate patient visit and show all work.
