are you sure you've remembered all the parts of this problem correctly? a solution of 250mg of dobutamine in 250ml of solution would be 1mg per 1ml, or 1000mcg per 1ml. (1 mg = 1000mcg) assuming that it is being given by microdrip tubing, which is how dobutamine is usually given, that would be 250mcg per minute (15 microdrops per 60 seconds reduces to 1/4 of 1000mcg). the ratio 250mcg per 70kg would be 4 mcg/kg of body weight per minute (rounded off). however, you're not supposed to assume anything. so, there is missing information here--like the kind of tubing being used.

Dobutamine is available in 250mg of 250ml of solution. It is being administered at 15gtt/min. The patient weights 70kg.
How many mcg per kg is the patient receiving per minute?
I had this on a test today and couldn't figure it out.
