i,- i,- i,- i,- i,- i,- i,- i,- i,-



(Enter numeric value only. If rounding is required, round to the

A client with cardiogenic shock weighs 220 lb and is receiving
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



dopamine at the rate of 3 mcg/kg/minute. The solution strength
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



available is dopamine 400 mg in 250 ml of D5W. The nurse
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



should set the infusion pump to deliver how many ml/hour?
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



(Enter numeric value only. If rounding is required, round to the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-

, First, convert pounds to kg, 220 lb : X = 2.2 lb : 1 kg = 100 kg.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



Next, calculate the dosage per minute, 3 mcg/kg/min x 100 kg =
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



300 mcg/min. Convert mcg/min to mcg/hour, 300 mcg/min x 60
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



min=18,000 mcg/hour. Convert mcg/hr to mg/hour, 18,000 i,- i,- i,- i,- i,- i,- i,-



mcg/hr = 18.0 mg/hour. Calculate the rate, 400 mg : 250 ml = 18
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



mg : X ml 400X = 4500 X = 11.25 = 11.3 ml. So, 18 mg/11.3 ml
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



should be infused at 11.3 ml/hour. i,- i,- i,- i,- i,-




A client with hypertension who weighs 72.4 kg is receiving an

infusion of nitroprusside (Nipride) 50 mg in D5W 250 ml at 75
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



ml/hour. How many mcg/kg/minute is the client receiving? (Enter
i,- i,- i,- i,- i,- i,- i,- i,- i,-



numeric value only. If rounding is required, round to the nearest
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



tenth.) 3.5 i,-i,- i,-




Calculate the mg/hour infusing, 50 mg : 250 ml = X : 75 ml 250X
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



= 3750 and X = 15 mg/hour. Next, convert mg/hr to mcg/hour,
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



15 mg/hour = 1 mg / 1000 mcg = 15,000 mcg/hour, then divide
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



by 60 min = 250 mcg/minute. Lastly, 250 mcg/72.4 kg/min = 3.45
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



= 3.5 mcg/kg/minute.
