The healthcare provider prescribes a hydration intravenous (IV) infusion of normal saline to run over 3 hours at 30 mL/hour for a client who is dehydrated and weighs 154 pounds. The nurse should program the infusion pump to deliver how many mL/hour?
(Enter numerical value only.)
The Correct Answer is ["30"]
To calculate the infusion rate, we need to use the formula:
Infusion rate (mL/h) = Volume (mL) / Time (h)
In this case, the volume and the time are given in the prescription, so we just need to plug in the values:
Infusion rate (mL/h) = 30 mL / 1 h
Simplifying, we get:
Infusion rate (mL/h) = 30 mL/h

Correct Answer is ["0.5"]
Explanation
To calculate the volume of heparin solution, we need to use the formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Plugging in the given values, we get:
Volume (mL) = 5,000 units / 10,000 units/mL
Simplifying, we get:
Volume (mL) = 0.5 mL
Rounding to the nearest tenth, we get:
Volume (mL) = 0.5 mL
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
