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.

Explanation
Here's the answer and explanation again:
We know:
Prescribed dose: 2 mg midazolam (given)
Vial concentration: 4 mg/mL (label)
We need to find the volume (mL) in the vial that contains the prescribed dose (2 mg) considering the concentration (4 mg/mL).
Calculation:
Volume to administer (mL) = Dose (mg) / (Concentration (mg/mL) / 2)
We divide the concentration by 2 because we need the volume that delivers 2 mg (half the concentration).
Volume to administer (mL) = 2 mg / (4 mg/mL / 2)
Volume to administer (mL) = 2 mg / 2 mg/mL
Volume to administer (mL) = 1 mL
Therefore, the nurse should administer 1 mL of midazolam from the vial to deliver the prescribed dose of 2 mg.

Explanation
Here's how to calculate the number of levothyroxine tablets the nurse should administer:
1. Convert client's weight to kilograms (kg):
Weight (kg) = Weight (pounds) / 2.205
Weight (kg) = 154 pounds / 2.205
Weight (kg) = 70 kg (rounded to nearest whole number)
2. Calculate the total levothyroxine dose in mcg:
Dose (mcg) = Dose (mcg/kg) x Weight (kg)
Dose (mcg) = 1.6 mcg/kg x 70 kg
Dose (mcg) = 112 mcg
3. Calculate the number of tablets based on the medication strength:
Number of tablets = Total dose (mcg) / Tablet strength (mcg/tablet)
Number of tablets = 112 mcg / 112 mcg/tablet
Number of tablets = 1
Therefore, the nurse should administer 1 tablet.
