First, convert pounds to kg, 220 lb : X = 2.2 lb : 1 kg = 100 kg. Next, calculate
the dosage per minute, 3 mcg/kg/min x 100 kg = 300 mcg/min. Convert
mcg/min to mcg/hour, 300 mcg/min x 60 min=18,000 mcg/hour. Convert
mcg/hr to mg/hour, 18,000 mcg/hr = 18.0 mg/hour. Calculate the rate, 400
mg : 250 ml = 18 mg : X ml 400X = 4500 X = 11.25 = 11.3 ml. So, 18 mg/11.3 ml
should be infused at 11.3 ml/hour.
A client is receiving Heparin Sodium 25,000 Units in 5% Dextrose Injection 500 ml IV

thromboplastin time (PTT) is 76 seconds. Based on the ACS protocol, the infusion
should be decreased by 100 units/hour for a PTT between 71 to 80 seconds. The nurse
should program the pump to deliver how many ml/hour? (Enter numeric value only.)
