You should deliver 219.67 mL/hr
Since the physician has ordered a continuous pain medication to be delivered at 25mcg/kg/hr and the available concentration is 8mcg/ml.
The patient weighs 155 lbs = 155 lbs × 1 kg/2.205 lb = 70.295 kg
We need to find the mcg/hr
<h3>mcg/hr</h3>
So, mcg/hr = mcg/kg/hr × weight of patient in kg
mcg/hr = 25 mcg/kg/hr × 70.295 kg
mcg/hr = 1757.37 mcg/hr
<h3>mL/hr</h3>
The mL/hr = mcg/hr ÷ concentration
mL/hr = 1757.37 mcg/hr ÷ 8 mcg/ml
mL/hr = 219.67 mL/hr
So, you should deliver 219.67 mL/hr
