Filgrastim 5 mcg/kg/day subcutaneous is prescribed for a child with cancer who weighs 88 pounds. The medication is labeled 300 mcg/mL. How many mL should the nurse administer daily to this child?
(Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.7"]
To answer this question, we need to convert the child's weight from pounds to kilograms, and then calculate the dose of filgrastim in mcg and mL for each day.
One pound is equal to 0.454 kg, so 88 pounds is equal to 88 x 0.454 = 39.952 kg.
The dose of filgrastim is 5 mcg/kg/day, so for a child who weighs 39.952 kg, the dose is 5 x 39.952 = 199.76 mcg/day.
The medication is labeled 300 mcg/mL, so to find the volume of medication in mL, we need to use a proportion: 300 mcg / 1 mL = 199.76 mcg / x mL
Cross-multiplying and solving for x, we get: x = (1 x 199.76) / 300
x = 0.66587 mL
This is the volume of medication that the nurse should administer daily to this child. Rounding to the nearest tenth, the answer is:
0.7 mL
The rationale for this answer is that we used the child's weight and the prescribed dose to find the amount of medication in mcg, and then used the concentration of the medication to find the volume in mL.

Correct Answer is ["400"]
Explanation
To calculate the infusion rate, we need to divide the total volume of fluid by the total time of infusion. In this case, we have 1,000 mL of 0.9% sodium chloride to be infused over 2.5 hours.
Therefore, the infusion rate is 1,000 / 2.5 = 400 mL/hour.
Correct Answer is ["125"]
Explanation
To answer this question, we need to find the infusion rate in mL/hour that will deliver 1 liter of lactate Ringers in 8 hours. We can use the following formula:
Infusion rate (mL/hour) = Volume (mL) / Time (hour)
We know that 1 liter = 1000 mL, so we can plug in the values into the formula:
Infusion rate (mL/hour) = 1000 mL / 8 hours
Infusion rate (mL/hour) = 125 mL/hour
Therefore, the nurse should program the infusion pump to deliver 125 mL/hour.
