Rn Hesi Dosage Calculations ( 32 Questions)
A continuous intravenous (IV) infusion of morphine at 15 mg/hour for pain control is prescribed for a client with end-stage lung cancer. The medication solution minibag is labeled, "50 mg/250 mL." The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only.)
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mg/h) x Volume (mL) / Concentration (mg)
Plugging in the given values, we get:
Infusion rate (mL/h) = 15 mg/h x 250 mL / 50 mg
Simplifying, we get:
Infusion rate (mL/h) = 75 mL / 2 h
Dividing both sides by 2, we get:
Infusion rate (mL/h) = 37.5 mL/h
