, A client with cardiogenic shock weighs 220 lb and is receiving dopamine at the rate of 3
mcg/kg/minute. The solution strength available is dopamine 400 mg in 250 ml of D5W.
The nurse should set the infusion pump to deliver how many ml/hour? (Enter numeric
value only. If rounding is required, round to the nearest tenth.) - CORRECT ANSWERS-
11.3

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.

3(100kg) =300

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
= 400 mg 18 mg
_____________ = ___________
250mL 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 with hypertension who weighs 72.4 kg is receiving an infusion of nitroprusside
(Nipride) 50 mg in D5W 250 ml at 75 ml/hour. How many mcg/kg/minute is the client
receiving? (Enter numeric value only. If rounding is required, round to the nearest
tenth.) - CORRECT ANSWERS-3.5

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

=250X = 3750 and X = 15 mg/hour.

Next, convert mg/hr to mcg/hour
