Nitroglycerin 30 mcg/minute is prescribed for a client who is admitted with chest pain. Nitroglycerin 100 mg is dispensed in a solution of 250 mL of D5W. The nurse should program the infusion pump to deliver how many mL/hour?
(Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["4.5"]
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

Correct Answer is ["133"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (mcg/min) x Weight (kg) x Volume (mL) / Concentration (mcg)
First, we need to convert the weight from pounds to kilograms by multiplying by 0.454. In this case, 132 pounds is equivalent to 59.928 kg.
Plugging in the given values, we get:
Infusion rate (mL/h) = 2 mcg/min x 59.928 kg x 500 mL / 45000 mcg
Simplifying, we get:
Infusion rate (mL/h) = 132.84 mL/h
Rounding to the nearest whole number, we get:
Infusion rate (mL/h) = 133 mL/h
Correct Answer is ["24"]
Explanation
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Dose (units/h) x Volume (mL) / Concentration (units)
First, we need to adjust the dose according to the sliding scale prescription based on the PTT result. In this case, since the PTT is less than 65 seconds, we need to increase the dose by 200 units/hour. Therefore, the new dose is 1,000 units/hour + 200 units/hour = 1,200 units/hour.
Plugging in the given values, we get:
Infusion rate (mL/h) = 1,200 units/h x 500 mL / 25,000 units
Simplifying, we get:
Infusion rate (mL/h) = 24 mL/h
