The primary healthcare provider (PHCP) prescribes dopamine at 5 mcg/kg/minute. The client weighs 80.9 kg (177.98 lbs). The medication label reads dopamine 800 mg in 500 mL of dextrose 5% water (D5W). How many mL per hour will the nurse administer to the client? Fill in the blank. Round your answer to the nearest whole number.
