Calculating New Fentanyl Infusion Rate

A nurse is assessing a patient who has been receiving a continuous infusion of fentanyl for postoperative pain management. The patient reports a pain level of 8 on a scale of 0 to 10. The healthcare provider orders a protocol adjustment for fentanyl, allowing for an increase in the infusion rate by 50%. If the current infusion rate is set at 1.5 mcg/kg/hr and the patient weighs 70 kg, what should the new infusion rate be? Calculate the unit dose as _____ mcg/kg/hr.
