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.)
The Correct Answer is ["602"]
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

Correct Answer is ["3.5"]
Explanation
To calculate the total volume of diluted medication, we need to use the formula:
Total volume (mL) = Drug volume (mL) + Diluent volume (mL)
First, we need to calculate the drug volume by dividing the dose by the concentration. In this case, 1 mg of hydromorphone is equivalent to 0.5 mL of hydromorphone injection.
Plugging in the given values, we get:
Total volume (mL) = 0.5 mL + 3 mL
Simplifying, we get:
Total volume (mL) = 3.5 mL
