Dopamine hydrochloride IV at 2 mcg/kg/minute is prescribed to promote renal perfusion for a client weighing 198 lbs. The pharmacy sends a pre-mixed bag of dopamine containing 400 mg in 250 mL dextrose 5% in water (DSW). An IV pump is available that provides a precision infusion rate to a tenth of a mL. The nurse should set the IV pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
