Amidst a late-night shift, Nurse Patel is attending a woman in preterm labor. The physician prescribes Ritodrine IV at a rate of 50 mcg/min. Upon receiving the medication, he observes that the pharmacy has prepared a premixed IV bag with 150mg of Ritodrine in 500mL D5W. As he gets ready to administer the medication, he wonders, "At what rate, in mL/hour, should I set the IV pump?" *
