The healthcare provider prescribes filgrastim 5 mcg/kg subqutaneous (SubQ) for a client who weighs 176 pounds. The available vial is labeled, "Filgrastim 300 mcg/mL. Based on the client's weight, how many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.3"]
Here's how to calculate the volume (mL) of filgrastim the nurse should administer:
Client weight conversion:
Client weight: 176 pounds
Since medication dosage is based on weight per kilogram (kg), we need to convert the weight to kg for accurate calculation.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 176 pounds / 2.205 lbs/kg
Client weight (kg) = 80 kg (round to nearest whole number)
Filgrastim dose per kg:
Dose per kg = 5 mcg/kg (given)
Filgrastim concentration:
The medication vial is labeled 300 mcg/mL. This indicates there are 300 mcg of filgrastim in every 1 mL of solution.
We need to find the volume (mL) containing the prescribed dose (based on weight) of filgrastim (5 mcg/kg) considering the concentration (300 mcg/mL) in the vial.
Total filgrastim dose (mcg): Dose (mcg/kg) x Client weight (kg)
Total filgrastim dose (mcg): 5 mcg/kg * 80 kg
Total filgrastim dose (mcg): 400 mcg
Volume to administer (mL): Total dose (mcg) / Concentration (mcg/mL)
Volume to administer (mL): 400 mcg / 300 mcg/mL
Volume to administer (mL) = 1.33 mL (round to nearest tenth)
Therefore, the nurse should administer approximately 1.3 mL of filgrastim subcutaneously.

Correct Answer is ["17"]
Explanation
Let’s calculate the solution step by step:
Calculate the Total Drops in the IV Bag:
The total number of drops in the IV bag can be calculated using the formula:
Totaldrops = VolumeinmL × DropspermL
Substituting the given values:
Totaldrops = 150mL × 10drops/mL = 1500drops
Calculate the Rate in Drops/Minute:
The rate in drops per minute can be calculated using the formula:
Rateindrops/minute = Totaldrops / Timeinminutes
Substituting the given values:
Rateindrops/minute = 1500drops/90minutes ≈ 16.67drops/minute
Since the problem asks for the rate to be rounded to the nearest whole number if necessary, the final rate is 17 drops/minute.
Correct Answer is ["100"]
Explanation
The medication is to be administered over 30 minutes,
so if we want to find out the rate in mL/hour,
we need to double the total volume because there are 60 minutes in an hour.
Therefore, the infusion pump should be set to deliver
50mL/30minutes × 60minutes / hour = 100mL/hour
So, the answer is 100. The nurse should program the infusion pump to deliver 100 mL/hour
