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 ["0.75"]
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 ["7200"]
Explanation
To calculate the amount of heparin received, we need to use the formula:
Amount (units) = Infusion rate (mL/h) x Time (h) x Concentration (units/mL)
First, we need to calculate the concentration of heparin in the solution by dividing the total units by the total volume. In this case, it is 20,000 units / 500 mL.
Plugging in the given values, we get:
Amount (units) = 15 mL/h x 12 h x 20,000 units / 500 mL
Simplifying, we get:
Amount (units) = 7,200 units
