Rn Hesi Dosage Calculations ( 32 Questions)
The healthcare provider changes a prescription for nitroglycerin intravenous (IV) infusion from 5 mg/min to 10 mg/min. The IV bag contains nitroglycerin 50 mg in dextrose 5% in water (D5W) 250 mL. The nurse should program the infusion pump to deliver how many mL/h? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mg/min) x Volume (mL) / Concentration (mg)
Plugging in the given values, we get:
Infusion rate (mL/h) = 10 mg/min x 250 mL / 50 mg
Simplifying, we get:
Infusion rate (mL/h) = 500 mL / 50 min
Converting minutes to hours, we get:
Infusion rate (mL/h) = 500 mL / 0.83 h
Dividing both sides by 0.83, we get:
Infusion rate (mL/h) = 602.41 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 602 mL/h
