A client with cardiogenic shock 11.3
weighs 220 lb and is receiving
dopamine at the rate of 3 First, convert pounds to kg, 220 lb : X = 2.2 lb : 1 kg
mcg/kg/minute. The solution = 100 kg. Next, calculate the dosage per minute, 3
strength available is dopamine 400 mcg/kg/min x 100 kg = 300 mcg/min. Convert
mg in 250 ml of D5W. The nurse mcg/min to mcg/hour, 300 mcg/min x 60
should set the infusion pump to min=18,000 mcg/hour. Convert mcg/hr to mg/hour,
deliver how many ml/hour? (Enter 18,000 mcg/hr = 18.0 mg/hour. Calculate the rate,

ml/hour.
A client with hypertension who 3.5
weighs 72.4 kg is receiving an
infusion of nitroprusside (Nipride) 50 Calculate the mg/hour infusing, 50 mg : 250 ml = X :
mg in D5W 250 ml at 75 ml/hour. 75 ml 250X = 3750 and X = 15 mg/hour. Next,

A client who weighs 176 pounds is 100
receiving an IV infusion with esmolol
