13.1 mL/hr. First calculate the dose: 70 kg × 5 mcg/kg/min = 350 mcg/min. Convert to mg/min: 350 mcg divided by 1000 = 0.35 mg/min. Convert to mg/hr: 0.35 × 60 = 21 mg/hr. Calculate concentration: 400 mg in 250 mL = 1.6 mg/mL. Finally: 21 mg/hr divided by 1.6 mg/mL = 13.125 mL/hr, rounds to 13.1 mL/hr.
