The healthcare provider prescribes epoetin alfa 50 units/kg subcutaneously (SubQ) twice daily (BID) for a client who weighs 126 pounds. The available vial is labeled, "10,000 Units/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 hundredth.)
The Correct Answer is ["0.29"]
Here's how to calculate the volume (mL) of epoetin alfa the nurse should administer:
1. Client weight conversion:
Client weight: 126 pounds
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) = 126 pounds / 2.205 lbs/kg
Client weight (kg) = 57.14 kg (round to nearest hundredth)
2. Epoetin alfa dosage:
Prescribed dose: 50 units/kg (given)
3. Epoetin alfa concentration:
Vial label: 10,000 Units/mL
4. We need to find the volume (mL) to administer that provides the prescribed dose (50 units/kg) based on the client's weight (57.14 kg) and the medication concentration (10,000 Units/mL).
Calculation:
Total epoetin alfa dose (units): Dose (units/kg) x Client weight (kg)
Total epoetin alfa dose (units): 50 units/kg * 57.14 kg
Total epoetin alfa dose (units): 2857 units (round to nearest whole number)
Volume to administer (mL): Total dose (units) / Concentration (units/mL)
Volume to administer (mL): 2857 units / 10,000 Units/mL
Volume to administer (mL): 0.2857 mL (round to nearest hundredth as requested)
Therefore, the nurse should administer approximately 0.29 mL of epoetin alfa subcutaneously.

Correct Answer is ["1"]
Explanation
First, let’s convert the client’s weight from pounds to kilograms since the dosage is prescribed in mcg/kg.
We know that 1 kg is approximately 2.2 lbs. So,
Weightinkg = 2.2154lbs ≈ 70kg
The prescribed dose is 1.6 mcg/kg.
Therefore, the total dose for this client would be:
Doseinmcg = 1.6mcg/kg×70kg = 112mcg
The medication is available in 112 mcg tablets.
Therefore, to administer a dose of 112 mcg, the nurse should administer 1 tablet
Correct Answer is ["168"]
Explanation
Here's how to calculate the total zidovudine dosage (mg) the nurse should prepare to administer:
1. Convert client weight from pounds to kilograms:
Client weight (kg) = Client weight (lb) / 2.2
Client weight (kg) = 185 lb / 2.2
Client weight (kg) = 84.1 kg (approximately)
2. Calculate the total zidovudine dose based on weight and prescribed dosage:
Dose (mg) = Dose (mg/kg) x Client weight (kg)
Dose (mg) = 2 mg/kg x 84.1 kg
Dose (mg) = 168.2 mg (round to nearest whole number as requested)
Therefore, the nurse should prepare to administer 168 mg of zidovudine.
