ml         250 ml              1 mg               3 mcg            1                  60 min

__ =      ______   x  ________    x    ________  x _______   x  _______   x 87.4 kg    = 78.66 ml/hr

hr            50 mg           1000 mcg             kg                min                 1 hour

or

87.4 kg x 3 mcg/kg/min = 262.2 mcg/min

ml          250ml        1 mg                        262.2 mcg           60 min

__ =    ______  x   _______         x    __________    x   _______     = 78.66 ml/hour

hr           50 mg             1000 mcg                 min                       hour

2.

ml         250 ml                   1 mg                287.7 mcg               60 min

___  x    _____        x   __________  x   __________    x  ___________    = 10.79 ml/hour

hr            400 mg              1000 mcg           1 min                       1 hr

3.

mg = 0.2 mg

        _______   x 26.1 kg = 5.2  mg

        kg
