A client with angina pectoris is receiving intravenous (IV) nitroglycerin 50 mg/250 mL of D5W to be infused over 24 hours via pump. How many mL/hour should the nurse program the infusion pump?
(Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["10"]
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Volume (mL) / Time (h)
Plugging in the given values, we get:
Infusion rate (mL/h) = 250 mL / 24 h
Simplifying, we get:
Infusion rate (mL/h) = 10.42 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 10 mL/h

Correct Answer is ["0.75"]
Explanation
To calculate the volume of interferon beta-1b solution, we need to use the formula:
Volume (mL) = Dose (mg) x Dilution factor (mL/mg)
The dilution factor is the ratio of the volume of sterile water to the amount of powder in the vial. In this case, it is 1.2 mL / 0.3 mg.
Plugging in the given values, we get:
Volume (mL) = 0.1875 mg x 1.2 mL / 0.3 mg
Simplifying, we get:
Volume (mL) = 0.75 mL
Correct Answer is ["0.9"]
Explanation
To calculate the volume of filgrastim solution, we need to use the formula:
Volume (mL) = Dose (mcg) / Concentration (mcg/mL)
First, we need to calculate the dose by multiplying the prescribed rate by the weight in kilograms. To convert the weight from pounds to kilograms, we multiply by 0.454. In this case, 190 pounds is equivalent to 86.26 kg.
Plugging in the given values, we get:
Volume (mL) = 5 mcg/kg/day x 86.26 kg / 480 mcg/mL
Simplifying, we get:
Volume (mL) = 0.897 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 0.9 mL
