A child weighing 52.5 pounds receives a prescription for asparaginase 4,780 IU IV. The vial is labeled, "Asparaginase 10,000 IU single-use vial. For IM use, reconstitute in 2 mL sterile sodium chloride, and for IV use, reconstitute in 5 mL". How many mL should the nurse administer?
(Enter the numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2.4"]
Step 1 is to identify the ordered dose and the correct available concentration based on the route of administration.
Ordered Dose: 4,780 IU
Route: IV (Intravenous)
Available Strength: 10,000 IU
Reconstitution Volume for IV: 5 mL
Step 2 is to calculate the volume to administer in milliliters (mL)
Volume = (Ordered Dose ÷ Available Dose) × Available Volume
Volume = (4,780 ÷ 10,000) × 5
4,780 ÷ 10,000 = 0.478
0.478 × 5 = 2.39
Volume to administer = 2.39 mL
Step 3 is to round to the nearest tenth
2.39 rounds to 2.4
Answer: 2.4

Correct Answer is ["125"]
Explanation
To calculate the infusion rate in mL/hour, we can use the following formula:
Infusion rate (mL/hour) = Volume (mL) / Time (hours)
In this case, the volume is 250 mL and the time is 2 hours. We can calculate the infusion rate as follows: 250 mL / 2 hours = 125 mL/hour
Correct Answer is ["120"]
Explanation
To calculate the infusion rate in mL/hour, we can use the following formula:
Infusion rate (mL/hour) = Dose (mg/minute) x 60 / Concentration (mg/mL) In this case, the dose is 2 mg/minute and the concentration is:
200 mg/40 mL = 5 mg/mL
We can calculate the infusion rate as follows:
2 mg/minute x 60 / 5 mg/mL = 24 mL/hour
However, the total volume of the solution is 200 mL. Therefore, we need to adjust the infusion rate to ensure that the medication is infused over the correct time period. If we divide the total volume by the infusion time, we can calculate the infusion rate required to deliver the medication over that time period:
200 mL / (120 minutes) = 100 mL/hour
So we need to adjust our initial calculation to ensure that we are infusing at a rate of 100 mL/hour. We can do this by using a proportion:
2 mg/minute x 60 / 5 mg/mL = X mL/hour x 1 Solving for X gives us:
X = (2 x 60 x 1) / 5 = 24 mL/hour
So we should program the infusion pump to deliver 6 mL/hour.
