2 [latex]\frac {mcg} {kg/min}[/latex] = 1000 mcg/1 mg x 400 mg/250 mL x 15 mL/hr x 1 hr/60 min x 1/72 kg = 5.6 mcg/kg/min

3 [latex]\frac {mcg} {kg/min}[/latex] = 1000 mcg/1 mg x 400 mg/500 mL x 22.5 mL/hr x 1 hr/60 min x 1/60 kg =  5 mcg/kg/min

4 [latex]\frac {mcg} {kg/min}[/latex] = 1000 mcg/1 mg x 300 mg/250 mL x 15 mL/hr x 1 hr/60 min x 1/55.4545 kg = 5.4 mcg/kg/min

5 [latex]\frac {mcg} {kg/min}[/latex] = 1000 mcg/1 mg x 2500 mg/250 mL x 15 mL/1 hr x 1 hr/60 min x 1/65 kg = 38.5 mcg/kg/min
