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 ["12000"]
Explanation
To calculate how many units of heparin a client with DVT should receive in 12 hours, the nurse should know the infusion rate and the concentration of heparin. The infusion rate is 25 mL/hour and the concentration of heparin is 20,000 units in 500 mL of solution.
To calculate the amount of heparin in one hour, multiply the infusion rate by the concentration and divide by the volume of solution. For example, (25 mL/hour x 20,000 units) / 500 mL = 1000 units/hour. To calculate the amount of heparin in 12 hours, multiply the hourly amount by 12. For example, 1000 units/hour x 12 hours = 12,000 units.
Therefore, the client should receive 12,000 units of heparin in 12 hours.
Correct Answer is ["600"]
Explanation
To calculate the infusion rate, we need to divide the volume of fluid by the time of infusion. In this case, we have a bolus of 200 mL of normal saline to be infused over 20 minutes.
Therefore, the infusion rate is 200 / 20 = 10 mL/minute. To convert this to mL/hour, we need to multiply by 60 minutes per hour.
Therefore, the infusion rate is 10 x 60 = 600 mL/hour.
