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 ["83"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
First, we need to convert the volume from liters to milliliters by multiplying by 1,000. In this case, 1 liter is equivalent to 1,000 mL.
To convert the time from hours to minutes, we need to multiply by 60. In this case, 12 hours is equivalent to 720 minutes.
Plugging in the given values, we get:
Infusion rate (gtt/min) = 1,000 mL x 60 gtt/mL / 720 min
Simplifying, we get:
Infusion rate (gtt/min) = 83.33 gtt/min
Rounding to the nearest whole number, we get:
Infusion rate (gtt/min) = 83 gtt/min
Correct Answer is ["4.5"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Volume (mL) / Concentration (mcg)
First, we need to calculate the concentration of nitroglycerin in the solution by dividing the total amount by the total volume. In this case, it is 100 mg / 250 mL.
Since 1 mg is equal to 1,000 mcg, we need to multiply the concentration by 1,000 to get the same units as the dose. In this case, it is 100,000 mcg / 250 mL.
Plugging in the given values, we get:
Infusion rate (mL/h) = 30 mcg/min x 250 mL / 100,000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 0.075 mL/min
To convert minutes to hours, we need to multiply by 60. In this case, it is 0.075 mL/min x 60 min.
Simplifying, we get:
Infusion rate (mL/h) = 4.5 mL/h
Rounding to the nearest tenth, we get:
Infusion rate (mL/h) = 4.5 mL/h
