A physician submits a medication order for a 110-pound patient calling for an intravenous drip (IV infusion) containing 400 mg of dopamine in a 250-mL bag of normal saline solution. The drip is to be run at 5 µg/kg/minute with an IV set that delivers 15 drops per milliliter. The pharmacist decided to use a stock solution of dopamine injection (40 mg/mL) to prepare the infusion. Calculate the infusion rate, in mL/hr, for this patient.
desired dose =5mcg/kg/mt
wt= 110 pound, convert into kg, 110pound=50kg
60minutes=1hr
convert mg into microgram, multiply 400 by 1000( 1mg=1000microgram)
400mg of dopamine added in 250ml NS
step1= convert mg ino microgram
=1600mcg
= 9 ml/hr
